They're taken to the neuro ICU, and they fortunately survive. But the journey does not end there. In fact, in some ways, the journey has just begun. Join us today as we unpack holistic care for ICH patients.  Dr Jones: This is Dr. Lyell Jones, Editor-in-Chief of Continuum. Thank you for listening to Continuum Audio. Be sure to visit the links in the episode notes for information about earning CME, subscribing to the journal, and exclusive access to interviews not featured on the podcast.  Dr Albin: Hello to our audience. This is Dr. Casey Albin. Today, I'm interviewing Dr. Wendy Ziai and Dr. Vishank Shah about their article on intracerebral hemorrhage. This article appears in the April 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast. I am so delighted that both of you are joining. To begin, let's just do a brief introduction of who you are and, and a little bit of how you got interested in the topic.  Dr Ziai: Hi, I'm Wendy Ziai. Thank you for having me on this podcast. I am a professor of neurology at Johns Hopkins. I am a neurointensivist, and I think I got primarily interested in this topic through clinical trials that I have been a part of since my fellowship days.  Dr Shah: Hi, everyone. I'm, uh, Vishank Shah. I am also, uh, very thankful for being invited to be a part of this podcast. I'm also a neurointensivist at Hopkins and the fellowship program director here for neurocritical care, and I'm interested in recovery after ICH, and that's why I'm a part of this work.  Dr Albin: Welcome to you both. It is such a treat for me to get to interview fellow neurointensivist, particularly those who have such a wealth of experience. So, I am delighted to dive into this. All right. So, to set the stage for our audience, intracerebral hemorrhage has long been approached with pessimism. But your article really highlights that there are meaningful advantages in prevention and risk stratification and long-term recovery for these patients. Though you both are neurointensivist, this article really emphasizes primary prevention and the holistic long-term care for the survivors. And so, to begin, Dr. Shah, can you just lay out a little bit for our listeners the scope of intracerebral hemorrhage and its community impact?  Dr Shah: Yeah. So, you know, ICH is the second most common type of stroke. There are more than three million new cases of ICH globally each year, and it accounts for thirty percent of all stroke types, but it is the one that has the highest mortality, with more than forty to fifty percent of the patients dying in the first thirty days, and then continued long-term impact on both functional as well as outcomes, as well as survivorship after the early period. And it also disproportionately impacts lower socioeconomic, and then minority races like Blacks, Asians, as well as Hispanic ethnicity. And so, there's a lot of work that needs to be done to reduce the burden of this disease.  Dr Albin: Absolutely. I mean, these can really be devastating for families, and I really am appreciative of your highlighting that there's a lot of disparities, and there's a lot of work to be done to really increase equity to these patients. I think a lot of this goes into really the AAN's focus on brain health and trying to improve some of what we're doing to maintain brain health. And I really wanted to kind of drill down on this because for ICH, there's a lot that can be done upfront as we think about how do we counsel patients who may walk into the office about strategies to prevent ever becoming an intracerebral hemorrhage patient. So, Dr. Shah, can you walk us through a little bit about what neurologists in the community need to be doing to make sure that no one ends up with us in the neurointensive care unit?  Dr Shah: Yeah, sure. So, I think, you know, one of the most important risk factors is, of course, hypertension and long-standing uncontrolled hypertension. And so really recognizing the need for early onset screening with regular blood pressure monitoring at a very early age, particularly in the races that I discussed earlier. And then I think another big part, obesity, metabolic syndrome, and type two diabetes. And I think there's a lot of interesting new work that with the GLP-1 agonist, you know, in a large multicenter cohort studies showing that patients receiving these had a significantly lower reduction risk of ICH. And so, this might be a really important part that, you know, clinicians need to start increasingly recognizing and using in their practice. And then, of course, other risk factors that are common include smoking, diet high in sodium, exposure to air pollution, both indoor as well as outdoor. And so, mitigating all of these risk factors can also reduce the burden of ICH.  Dr Albin: Absolutely. And I really want to highlight that hypertension plays such an important role and that we as neurointensivist, as community neurologists, really need to be creative about ways that we can help people meet those blood pressure target and meeting people in the community where they are, making sure that they're not suffering from side effects from their medication that would prevent them from sticking with it long term. Dr. Ziai, anything else to add about what we can do in the community?  Dr Ziai: So, we really want to emphasize, even in the acute phase, that patients moving forward need to have targeted interventions to reduce blood pressure, smoking, enhance their physical activity, have a diet that is high in fruits and vegetables and low in alcohol and salt, and then promoting weight loss, of course.  Dr Albin: And Dr. Ziai, I'm gonna ask you a little bit about one of the things that maybe not all of our listeners have heard about is this APOE2, APOE4 genetic risk for intracerebral hemorrhage. What's going on there and, and should clinicians be testing for that? Dr Ziai: That's a great question, and it is not one that we currently test people for at least acute ICH presentation. APOE2 and A4- E4 alleles, these give patients a two to three times higher risk of ICH by increasing cerebral amyloid deposition. And if you happen to have APOE2 carrier ship status, then along with other risk factors like white matter disease and vascular risk factors, these predict the onset of new microbleeds even during very short follow-up periods of about two years. And as we know, having cerebral microbleeds are associated with an increased risk of all strokes, ischemic and ICH, but they are one of many MRI markers of small vessel disease, which along with cortical superficial siderosis, does significantly increase future ICH risk. And so even in people who've never had an ICH, if they happen to have an MRI, it may be reasonable to look at the MRI and incorporate this burden of small vessel disease, and especially these hemorrhagic markers into, uh, decision-making about interventions.  Dr Albin: That's a really excellent point. And so, I think that your article did a really beautiful job of thinking holistically about the patient, incorporating clinical markers of their risk for having ICH, but also those radiographic markers. I'm just gonna ask you to summarize those again one more time because not everyone will be familiar with these. So, when you're looking at an MRI, what are the things that you're particularly clued in on that would increase the patient's risk of future ICH?  Dr Ziai: In the past, what we're looking for really is markers of cerebral amyloid angiopathy, which significantly increase a person's risk for lobar hemorrhage in particular. And so, we have a set of criteria called the Boston Criteria, and there's a new version of these, version 2.0. And these, um, incorporate a number of imaging markers that provide a very high sensitivity and specificity to diagnose CAA after an ICH. But even if someone's never had an ICH, and they evaluate that risk-benefit ratio for different cardiovascular prevention strategies. And so, the markers that we're specifically interested in are, of course, microbleeds. But not just having microbleeds, but are they lobar or are they deep? Lobar having a higher risk for lobar ICH.

    Stroke in Children and Younger Adults With Dr. Thalia S. Field

    Stroke in children and younger adults differs significantly from adult stroke, with varied presentations and a broader range of underlying causes such as congenital heart disease and arteriopathies. This episode highlights key diagnostic considerations and evolving approaches to treatment in these younger populations. In this episode, Aaron L. Berkowitz, MD, PhD, FAAN, speaks with Thalia S. Field, MD, FRCPC, MHSc, coauthor of the article "Stroke in Children and Younger Adults" in the Continuum® June 2026 Cerebrovascular Disease issue. Dr. Berkowitz is a Continuum® Audio interviewer and a professor of neurology in the Department of Neurology at the University of California, San Francisco, in San Francisco, California. Dr. Field is a professor at the University of British Columbia and the Sauder Family Heart and Stroke Professor of Stroke Research, and a stroke neurologist at the Vancouver Stroke Program, Vancouver Coastal Health in Vancouver, British Columbia, Canada.

But stroke can also occur in children, in infants, and even in utero. Today, I have the privilege of interviewing Dr. Thalia Field to talk about pediatric stroke.  Dr Jones: This is Dr. Lyell Jones, Editor-in-Chief of Continuum. Thank you for listening to Continuum Audio. Be sure to visit the links in the episode notes for information about earning CME, subscribing to the journal, and exclusive access to interviews not featured on the podcast.  Dr Berkowitz: This is Dr. Aaron Berkowitz, and today I'm interviewing Dr. Thalia Field about her article on stroke in children and younger adults. This article appears in the June 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast, Dr. Field, and could you please introduce yourself to our audience?  Dr Field: Well, thanks so much. It's a pleasure to, uh, be speaking to you. I'm a stroke neurologist, and I treat adults generally. My wonderful colleague, Thivya Selvanathan, who's a neonatal neurologist, co-wrote the chapter with me. We do, unfortunately, have to treat some children with stroke collaboratively and I do advise on those cases. My practice is about one-quarter clinical, so I treat patients with acute stroke, look after them on the wards, see patients in stroke prevention clinic, and the rest of my time is mainly research and some administrative work and teaching. I run the clinical trials program for the Vancouver Stroke Program, and I do research of my own, mainly focused on stroke in younger adults. We previously did a trial and registry on cerebral venous thrombosis, and more recently, I've been running a national study looking at brain health in adults and children with congenital heart disease.  Dr Berkowitz: Fantastic. Wow, that is a lot that you do, and we'll look forward to the results of some of those studies. So, when adults suffer a stroke, they typically present with sudden onset focal neurologic deficits, very common scenario we're consulted on.  And one thing you and your colleague talk about in the article is that strokes can present differently in infants and in young children. Can you talk a little bit about the differing clinical presentations of stroke in the youngest young as compared to our usual experience treating the older adults?  Dr Field: Sure. So, you know, speaking about this as someone who doesn't see the children directly but has had the opportunity to discuss these patients with my colleagues and, like we all do, learn about it during our training, I think one of the distinctions, especially with neonates, is that it's generally not a presentation with focal neurologic deficits. Often these babies will have seizures or encephalopathy as their main presentation, and sometimes we're only finding out after the fact if they're presenting with developmental delay or early preference for handedness and hypotonia, things like that. So, in very young children, that's a distinction. And in older children, there can be sudden onset deficits and, and unfortunately, sometimes these are mistaken for other conditions that are more common in children, like seizures. But sometimes you can have a more indolent course, say, with something like a focal cerebral arteriopathy or something like that. So, it depends on the scenario, but the big difference primarily is in neonates, as far as I understand.  Dr Berkowitz: Perfect. That's very helpful. So as an adult neurologist, when I think about causes of stroke or teach sort of the categories of causes of stroke to our residents and students, when we think about the evaluation of stroke, I divide them broadly into causes related to the heart, causes related to the blood vessels, and causes related to the blood with, in the adult world, the most common things, of course, being atrial fibrillation for the heart, atherosclerosis for the blood vessels, and then risk factors for atherosclerosis in the blood, diabetes, hyperlipidemia, very rarely picking up a hypercoagulable disorder in the blood column. And reading your article, it seems that, correct me if I'm wrong, stroke in young adults, stroke in the pediatric population can basically be organized into those same broad categories, heart, blood vessels, and blood, just that there's many more conditions on the differential diagnosis that you would consider in young adults to begin with and then children and then neonates as we get into the younger and younger population. So, I'd like to talk about each of these sort of buckets of etiology in turn and ask you about some of the causes we would consider in young adults and children in each of these, and then as they come up, probably ask you more questions about how frequently we find these sorts of things, how frequently they're the cause of stroke treatment, et cetera. So, let's start with the heart. As I said, in adults, we're mostly looking for rhythm disorders, right, atrial fibrillation. Sometimes we'll pick up a patent foramen ovale or PFO or other structural abnormalities, but mostly we're thinking about atrial fibrillation. But reading your paper, I was struck by the huge variety of conditions that you might be looking for in the heart in children or infants with stroke. So, can you tell us a little more about cardiac etiologies of stroke in the young?  Dr Field: Yeah. So, I'd say unlike in older adults, where it tends more often to be a rhythm disorder, in children and adults who are younger, it's primarily a structural cause, and congenital heart disease being the most common. And it changes a little bit from younger adults shifting downwards in age to younger children in terms of the fact that often if we're seeing an adult with stroke related to congenital heart disease, it can be a paradoxical embolism from a previously undiagnosed PFO. Not in all cases, but fortunately this is improving over time. You know, generally people with diagnoses of more severe congenital heart disease are followed up from childhood and people are aware of the diagnosis, and hopefully they're being managed and watched for things like premature arrhythmias or depressed heart function or other things that can develop and require their own distinct antithrombotic management, for example. In young children, however, more severe causes of congenital heart disease tend to more frequently be associated with stroke. And in many cases, those strokes can be early on in life or associated, say, with perioperative complications or other iatrogenic-related causes in, in that way. Again, congenital heart disease can be associated with stroke at, at any point in the life course. But as adult neurologists, most frequently we're seeing very simple lesions like PFO with large shunts, and in children, it tends to be the more complex causes of congenital heart disease.  Dr Berkowitz: Got it. So, let's move on to the blood vessels. Again, in adults, we're usually thinking about atherosclerotic disease, be that of the cervical arteries or of the intracranial arteries. But in your paper, a lot of discussion about the various vasculopathies, arteriopathies that can be cause of stroke in younger adults and in children. Could you talk a little bit more about some of the vasculopathies and vascular conditions that are causes of stroke in the younger population?  Dr Field: Sure. Before I do that, I will say that especially in older younger adults, particularly over the age of thirty-five, and you know, kind of makes me shudder that that's an older younger adult. But, um, in, in any case, certainly conventional vascular risk factors are more common in this population with stroke, especially in those who don't have PFO-associated stroke. Like conventional atherosclerosis, you know, certainly is a cause of stroke in younger adults. But that being said, certainly other vascular causes and vasculopathy in particular is a much more common cause of stroke in younger adults and, and children than it is in older adults. In particular, dissection is an extremely common cause of stroke in younger adults. Generally cervical artery dissection from non-inflammatory vasculopathy, usually on, sometimes on the FMD fibromuscular dysplasia spectrum and, and sometimes, you know, provoked by minor trauma or something post-infectious that may make the vessels a little bit more suscep

    Thrombolysis, Thrombectomy, and Antithrombotic Therapy for Acute Ischemic Stroke With Dr. Christopher R. Leon-Guerrero

    Rapid advances in acute ischemic stroke care have expanded treatment windows and improved patient outcomes through thrombolysis, mechanical thrombectomy, and optimized antithrombotic strategies. This episode highlights evolving approaches to patient selection, the growing role of tenecteplase, and the importance of team-based systems of care in delivering timely, effective treatment. In this episode, Casey S. Albin, MD, FAAN, speaks with Christopher R. Leon Guerrero, MD, author of the article "Thrombolysis, Thrombectomy, and Antithrombotic Therapy for Acute Ischemic Stroke" in the Continuum® June 2026 Cerebrovascular Disease issue. Dr. Albin is a Continuum® Audio interviewer, associate editor of media engagement, and an assistant professor of neurology and neurosurgery at Emory University School of Medicine in Atlanta, Georgia. Dr. Leon Guerrero is an associate professor of neurology and the adult neurology residency program director at Atrium Health Carolinas Medical Center in Charlotte, North Carolina, where he also serves as outpatient stroke director.

Thank you for listening to Continuum Audio. Be sure to visit the links in the episode notes for information about earning CME, subscribing to the journal, and exclusive access to interviews not featured on the podcast.  Dr Albin: Hello and welcome. This is Dr. Casey Albin. Today, I'm interviewing Dr. Christopher Leon-Guerrero about his article on Thrombolysis, Thrombectomy, and Antithrombotic Therapy for Acute Ischemic Stroke. This article appears in the April 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast. I always like to start by just having you introduce yourself so our listeners know a little bit about you.  Dr Leon-Guerrero: Thanks for the introduction, Dr. Albin. Really glad to be here today. My name is Chris Leon-Guerrero. I'm a vascular neurologist at Atrium Health in Charlotte, North Carolina, at Carolinas Medical Center. I'm an associate professor in the Department of Neurology. I serve as our Neurology Residency Program Director, and I also wear the hat of an outpatient stroke director in our clinics.  Dr Albin: So, you are wearing a lot of hats and balancing a lot of things, and it's a really exciting time to be talking about this. For our listeners, we are recording this right after the launch of the American Heart Association, American Stroke Association just released their new guidelines on acute ischemic care. So, no better time to kind of dive into some of this. And really, when I think about acute ischemic stroke care, it's dramatically transformed in the last two to three decades. I mean, from lengthening time windows for IV thrombolysis to expanded thrombectomy eligibility, this is really, I think, some of the most exciting stuff in neurology. And your article did a fantastic job of distilling those rapid advancements and clarifying some of the evidence behind some of these new evolving treatment selections and imaging modalities, and it's exciting. So, let's just start with thrombolysis. Where are we now with IV thrombolytics and the time windows there?  Dr Leon-Guerrero: So, a lot has changed in the last decade, since that initial trial with NINDS, nearly thirty years ago. We're still giving intravenous thrombolysis in the traditional time window up to 4.5 hours, and really emphasizing we should be selecting patients for treatment early and quickly as possible. In most of those cases, a non-con head CT is sufficient to rule out bleeding and initiate treatment as quickly as possible. Where things have gotten really exciting is using advanced neuroimaging to help select patients beyond that traditional 4.5 hour window, and we're able to treat patients even up to twenty-four hours from symptom onset.  Dr Albin: Which is really exciting. It has really totally shifted the paradigm here. You know, I think most listeners are going to be pretty familiar with three to four and a half hours. Like, that's sort of our standard. What can you tell us about some of the advanced imaging we're using for that later selection period?  Dr Leon-Guerrero: It's around the principle of you want to be able to, uh, rescue significant salvageable tissue without a lot of core. So, this large profusion deficit and small core is really how you're trying to select out these patients. And two types of modalities are used. One is going to be MRI, and a lot of those imaging protocols, you know, are outlined in the WAKE UP trial and basically are looking for patients with DWI hyperintense lesions and FLAIR negative lesions to suggest that patients in an early time window that's treatable for thrombolysis. And then in the other category, we'll be using profusion imaging, whether that's CT profusion or MR profusion, to look for patients with large salvageable tissue.  Dr Albin: Yeah. And I think that this has been one of the things that, to me, has been really impactful is I think when WAKE UP came out, it was exciting. It was fun to sort of think about, "Hey, we're going to be able to use MRI." But MRI can be very challenging to get acutely, especially in community centers where they don't have the capabilities to get someone from the emergency department into an MRI rapidly enough to make thrombolysis decisions. So, to see some of that expand to CT profusion has been really exciting. How are you going about sort of counseling patients or thinking about their risk when you're using some of those, like, advanced imaging techniques?  Dr Leon-Guerrero: Yeah. I think it's similar to the conversations we've had with patients even within the traditional 4.5 hour window. The risk for intravenous thrombolysis is hemorrhage, and counseling patients on the, you know, the risk and benefits of hemorrhage and the potential clinical benefit of receiving thrombolytics is important. And then providing patients with that information to make an informed decision, so that they can make the best decision for their own care.  Dr Albin: Totally. And it's, again, time sensitive, but trying to give families enough information and enough time to sort of process those, especially when it's a little bit beyond the standard that we're so used to consenting for. The other big area that's really changed is that tenecteplase has become the star of the show. It's really gained momentum, so what should clinicians understand about this?  Dr Leon-Guerrero: Yeah. There's been an explosion of data over the last decade on tenecteplase supporting its use for clinical practice. You know, there was recent updates even from the neurology journal with a large meta-analysis with all of the data showing good clinical outcomes and perhaps even lower risk of bleeding. And so, I think you're seeing a lot of centers across the country switching from alteplase to tenecteplase. There's some practical advantages. So tenecteplase is a one-time bolus dose. And then biologically, it seems to have better fibrin specificity, longer half-life, which may ultimately make it a more attractive drug and may make it even more effective. But I think the practical aspects of tenecteplase are not to be understated. I think there's a lot of advantages for speed and efficiency and for centers to make that switch.  Dr Albin: Yeah. I remember when our health system made the pivot from alteplase to tenecteplase. Like any changes, that obviously created some adjustments with the new workflow. But, the fact that this could be given just as a one-time dose and not with the "we got to calculate the bolus, and now we got to get the infusion on board," like really simplified workflow. So, I think that's been pragmatically one of the nicest things we've done in stroke care. Really exciting.  Dr Leon-Guerrero: Yeah. And, you know, it's a doable thing. I think you have to be, very deliberate about it at whatever center you're at to make sure that all stakeholders are aware of that change. I think that's helpful to get everybody involved and have a lot of planning to avoid wrong dosing errors or inadvertently dosing as alteplase versus tenecteplase. But it's certainly doable, and I think in the long term, centers that have switched have been pretty satisfied with tenecteplase.  Dr Albin: And you know, initially when this came out, there really was sort of a debate about, is it gonna be 0.25? Was it gonna be 0.4? Where have we landed with that debate?  Dr Leon-Guerrero: So, I think we found the correct dose is 0.25 milligrams per kilogram is the recommended dose with a max out of 25 milligrams. There's some within the American Heart Association guidelines that were just published. They mentioned even tier dosing based on 10 kilograms, so intervals. So, that may be an easier way for centers to do it. But that cap out dose of 25 milligrams at 0.25 milligrams per kilogram, I think, is the sweet spot.  Dr Albin: Yeah. That's great, and I think that that has helped, you know, say, "This is what we're doing. There's not a debate that's happening anymore." And that really just got codified in the new ASA guidelines, so really exciting there. So, there is a lot of guidance for these patients,

But for some, medical complications such as stroke can lead to devastating disability and sometimes even death. Today, we're going to learn about pregnancy and postpartum stroke, including stroke risk evaluation and best practices in management and risk reduction to help our pregnant and peripartum patients reduce stroke risk and achieve best possible outcomes.  Dr Jones: This is Dr. Lyell Jones, Editor-in-Chief of Continuum. Thank you for listening to Continuum Audio. Be sure to visit the links in the episode notes for information about earning CME, subscribing to the journal, and exclusive access to interviews not featured on the podcast.  Dr Nevel: Hello, this is Dr. Kait Nevel. Today, I'm interviewing Dr. Michelle Leppert about her article on pregnancy and stroke risk. This article appears in the June 2026 Continuum issue on cerebrovascular disease. Michelle, welcome to the podcast, and please introduce yourself to the audience.  Dr Leppert: My name is Michelle Leppert. I'm a stroke neurologist, and I currently work at the Tufts Medical Center in Boston, Massachusetts.  Dr Nevel: Thank you so much for being here, Michelle, and I'm looking forward to talking to you about your article. I always love starting with the question, what's the most important takeaway from your article for the practicing neurologist?  Dr Leppert: I think in this article, I'm trying to highlight that during pregnancy and especially postpartum, there's a heightened risk of stroke for women, and that's important for clinical neurologists to understand that this is a particularly vulnerable time for the population that we take care of. I think that one of the few of the things that could be informing this heightened stroke risk are the physiological changes that women undergo during pregnancy. So, that includes coagability, where there's an increased likelihood of clotting, and also the cardiovascular adaptations, including increased cardiac output and having an increased cardiac volume. And all of these mechanisms all contribute to the increased risk of strokes around pregnancy and postpartum.  Dr Nevel: Great. Thanks for that. What are some of the unique aspects of stroke types in etiology in pregnancy that we should be aware of?  Dr Leppert: When we think of strokes overall, generally the majority of our strokes are ischemic. So, for the overall population, about eighty-seven percent of strokes are ischemic, while the remainder are hemorrhagic. However, interestingly, during pregnancy, what we're seeing is about half of our strokes become hemorrhagic strokes, and now only a half of our strokes are ischemic, and this is in contrast to what we see in the overall population. One of the reasons is because pregnancy is associated with preeclampsia, and preeclampsia increases the risk of hemorrhagic stroke during pregnancy.  Dr Nevel: Can you tell us just more about headache in general in pregnancy and association of headache with secondary causes of headache and how that relates to stroke risk in this patient population? It seems like in this patient population that when somebody has a headache, we need to be very careful in our headache questions and evaluation.  Dr Leppert: Yeah. And I think the most concerning symptom that we're finding in this population is headaches, and the reason is because headaches is one of the clinical signs of having preeclampsia, which dramatically increases your risk of having a stroke, and especially a hemorrhagic stroke. So just to back up, we can talk about blood pressure for a little bit and some of the pathophysiologic changes during pregnancy. What most people may not know is that there's a dramatic vascular expansion that occurs during pregnancy. And somewhere during the second trimester, your blood pressure is actually the lowest. So, it can drop below pre-pregnancy levels and make your blood pressure appear low for the baseline. However, during the third trimester, as the baby is growing, there is increased vascular volume. The blood pressure starts to increase. We're seeing some of the highest prevalence of blood pressures, which is a sign for preeclampsia, and headaches develop during that third trimester, and particularly during the time around delivery and postpartum. And one of the most concerning signs, the most common sign of preeclampsia is having a headache. So, I think that with any patient that's presenting with a headache, especially during the third trimester or after delivery, that we really need to pay attention and take their blood pressure. That's one of the easiest clinical indicators that something could be going very wrong. Some of the other red flags clinically that we look for in headaches is that acute onset of a severe headache. That headache quality is different from what they usually have. Any woman with focal neurological symptoms associated with their headache, kind of excessive nausea and vomiting that's not characteristic for them. Not getting any relief with medications, and then lastly, checking that blood pressure is very important.  Dr Nevel: And what are the thoughts on blood pressure management in this patient population? I know that there is a little bit of difference in guidance in some of the obstetric societies on how we should manage blood pressure in this patient population. And then, is there anything beyond blood pressure management that we should be thinking about doing for this patient population to reduce their stroke risk?  Dr Leppert: I think that's a good question, and I hadn't really understood that this could be an area of controversy, cause my practice is mostly in stroke, and for most of adult population, the guidelines for blood pressure is very clear. We treat everybody over 130/80. If you're elderly, then your blood pressure limit might be a little higher. However, there's disagreement in the OBGYN guidelines from the American guidelines to the European guidelines. So, what the current American guidelines suggests is that if you have a history of chronic hypertension, then we would want your blood pressure treated during pregnancy below 140/90. However, if you don't have a history of chronic hypertension, then we allow the blood pressure to be higher and then it's an acute intervention if it's anything over 160. One of the issues with this strategy that is concerning is we had just mentioned that the pathophysiology of a pregnancy where you have the lowest blood pressure in that second trimester, and so your blood pressure may be abnormally good. [laughs] And it appears that it's better than your baseline. And so, by the OBGYN definition, any gestational blood hypertension is considered at 20 weeks and later. Sometimes these blood pressures are masked in some women who are pregnant. I think regardless of the controversy and what the practice should be, the focus is that most of the strokes are happening actually peripartum and postpartum, right? So, the woman's no longer pregnant. It is these time periods of the highest risk that we wanna make sure that the blood pressure is controlled. So, after the woman delivers the baby, we're no longer, you know, hampered by the whatever is chronic or gestational. We should be treating that blood pressure to 140/90. I think that not focusing on the controversy until the science catches up is probably what we should do. But like, really, the message here is that we should be checking women around the time of delivery and also postpartum, that we can't forget about their blood pressures postpartum, cause it actually doesn't peak until day five after they deliver the baby.  Dr Nevel: Does knowing that, that blood pressure peaks around day five, do you think that that should impact how we counsel patients in checking their blood pressure at home? Cause most women at day five are home. They're not still in the hospital.  Dr Leppert: Yeah, I think that's a really good point. One of the best interventions has been having a blood pressure at home for pregnant women. So even during their pregnancy and then postpartum, allow them to check their blood pressures, cause there's... Most of the cases, to be honest, that I've seen of preeclampsia and intracranial hemorrhage has happened postpartum. And I think what's unfortunate is that the woman is at home, they're distracted cause they have a newborn baby. They have a headache. They're just taking some Tylenol. And then if you have that blood pressure cuff readily accessible, that's a, a really easy way for

    Stroke Prevention With Dr. Mitchell S.V. Elkind

    Primary stroke prevention is a critical opportunity for neurologists, with most stroke risk driven by modifiable factors such as hypertension and lifestyle behaviors. This episode highlights practical tools and strategies, including Life's Essential 8 and contemporary risk calculators, while also exploring evolving approaches to shared decision making and secondary prevention. In this episode, Katie Grouse, MD, FAAN, speaks with Mitchell S. Elkind, MD, MS, FAAN, author of the article "Stroke Prevention" in the Continuum® June 2026 Cerebrovascular Disease issue. Dr. Grouse is a Continuum® Audio interviewer and a clinical assistant professor at the University of California, San Francisco in San Francisco, California. Dr. Elkind is the Chief Science Officer for Brain Health and Stroke at the American Heart Association in Dallas, Texas, and a professor of neurology and epidemiology at Columbia University in New York, New York.

Today, I have the opportunity to interview Dr. Mitchell Elkind, who wrote the article on stroke prevention in the newest Continuum issue on cerebrovascular disease.  Dr Jones: This is Dr. Lyell Jones, Editor-in-Chief of Continuum. Thank you for listening to Continuum Audio. Be sure to visit the links in the episode notes for information about earning CME, subscribing to the journal, and exclusive access to interviews not featured on the podcast.  Dr Grouse: This is Dr. Katie Grouse. Today, I'm interviewing Dr. Mitchell Elkind about his article on stroke prevention. This article appears in the June 2026 Continuum issue on cerebrovascular disease. Welcome to the podcast, and please introduce yourself to the audience.  Dr Elkind: Thank you so much, Katie. So, my name is Mitch Elkind, and I'm the Chief Science Officer for Brain Health and Stroke at the American Heart Association and a stroke neurologist by background.  Dr Grouse: Well, I just want to start by saying that I really enjoyed reading this article. I think this is just a really wonderful article I recommend strongly. Such a high yield, an important topic for a lot of us who see patients who are interested in learning about their stroke risks or need help with, uh, stroke prevention after having a stroke. So, I wanted to start. What's changed in the last couple of years? You know, what are some big highlights that you really want to stress that are different from maybe the last time we reviewed this topic?  Dr Elkind: Sure. Well, there's been a lot of development in the field of secondary stroke prevention, for one thing. But even beyond that, I think we increasingly appreciate how important it is to control what we call the social drivers of health on the earlier side, primordial or primary prevention. And that has been a big advance, I'd say. And I would also say, I think it's really important for neurologists to understand some of those questions about primordial and primary prevention. You know, we tend to get involved with patients after they've had a stroke or maybe a TIA, some kind of event. But sometimes we find people who are following for, you know, non-stroke related conditions who have risk factors also. And we can really play an important role in identifying those risk factors and helping to prevent a first stroke or vascular event as well. So, I think it's real important for us to be doctors even before we're neurologists. So, you know, Katie, about ninety percent of stroke risk is modifiable, so we can do a great job as neurologists in preventing stroke. And one of the most important things that we can do is to identify and treat high blood pressure. And recently, actually, the American Heart Association, American College of Cardiology guidelines on the management of hypertension have said that treatment of high blood pressure not only prevents stroke, but it can also help to prevent cognitive decline and dementia. And this is the first time that we've had a class of recommendation one and level of evidence A, the highest level of recommendation we give for the use of blood pressure treatment to prevent dementia. And that's largely based on the results of some large trials that have come out recently showing that you can prevent dementia with blood pressure control. So that's a really exciting link, I think, between cardiovascular risk factor control and subsequent brain health. It just illustrates the role that neurologists can play in, so many conditions outside of stroke as well.  Dr Grouse: That's a really great point, and I want to get a little more into the idea of primordial stroke prevention. Can you tell us a little bit more about what that might be?  Dr Elkind: So primordial prevention refers to addressing how we can prevent risk factors from occurring in the first place, and how can we improve the environments in which people live. You know, we know that only about twenty percent of health outcomes is dependent on what happens between the patient and their doctor in the office. About eighty percent of it is due to what happens in the environments in which we live, work, pray, and play. And so that's what we mean when we refer to the social drivers of health. What is the neighborhood like where somebody lives? Do they have access to healthy food? Do they have places where they can go to exercise? Is there air pollution in the area that may affect their health? You know, one really interesting fact that's become apparent in the last few years is that air pollution is a major risk factor for stroke. Something like a sixth of all strokes can be attributed to the quality of air. And so, what are the things we can do at the broader public policy, community level to reduce the risk of risk factors like high blood pressure and diabetes even before somebody has an event that brings them to the attention of the doctor? So that's what we're thinking about with regard to primordial prevention. It's the earliest stage in prevention.  Dr Grouse: And that's really fascinating. You know, I think an area that we haven't, as neurologists, really put a lot of our time thinking about, but clearly a very important thing. I really appreciated reading your article about how you incorporated the fact that, you know, a lot of these risk factors overlap very, very closely with all the risk factors for various types of cardiovascular events. And I would imagine that the work you've done as the Chief Clinical Science Officer for the American Heart Association has informed a lot of the way you've thought about-Trying to bring all these risks together and think a little bit more holistically about the whole thing. Could you tell us a little bit more about that and the work that you've done on the American Heart Association's Life's Essential 8 score?  Dr Elkind: Sure. I can't take credit for it. It's really work that was done by others at the Heart Association, particularly a cardiologist and epidemiologist named Don Lloyd-Jones. But many other volunteers participated. Life's Essential 8 is our approach to primary stroke prevention and cardiovascular prevention more broadly. We say Life's Essential 8 because it includes four health behaviors and four health factors that people can observe to reduce their risk of cardiovascular disease. The four factors are kind of things like know your numbers, your blood pressure, your blood sugar, your body mass index, right, which is a combination of weight and height, and your cholesterol level. So, know those numbers and keep them within the recommended ranges, and talk to your doctor if they're not. And then four lifestyle behaviors. So, one of them is to eat a healthy diet, and typically that means the Mediterranean diet. It means getting regular exercise, and we recommend 150 minutes a week of moderate to vigorous physical activity. Of course, it means abstinence from smoking or other tobacco products. And the last one, the eighth one, which I was so excited about when we added this, is sleep, recommending at least seven hours of sleep a night. So, I was really excited about this because we used to talk about Life's Simple 7, and then the last iteration of our recommendations included this recommendation for adequate sleep because of the mounting evidence of the importance of sleep to cardiovascular health. But sleep is really a brain function, right? And so, it was really the first, in a way, specific brain function that was added to our recommendations. So that's Life's Essential 8. People can read about it online at heart.org and recommend it to your patients as a simple way for people to understand the best approach to reducing their risk of cardiovascular disease, including stroke.  Dr Grouse: I checked it out myself after reading the article. It's very accessible to patients. It's a great education tool. And they can, you know, see their own score and use that in their own way to, to think about what their risks are and how they can help mitigate and then rescore themselves down the line. There's also, though, on the kind of more the clinician side, the PREVENT calculator as well. Could you tell us a little bit more about how we could use that in approaching this patient population?  Dr Elkind: Yeah. So, I think of Life's Essential 8 as being a patient-focused t

    Social Determinants of Health and Their Impacts on Stroke Prevention and Outcomes With Dr. Nneka Ifejika

    Social determinants of health, including housing, food access, insurance status, and structural inequities, significantly influence stroke prevention, recovery, and long term outcomes. These factors affect biological risk, treatment adherence, and disparities in care, even when traditional clinical measures are addressed. This episode highlights practical strategies for integrating screening, leveraging multidisciplinary teams, and identifying opportunities for advocacy to improve patient outcomes. In this episode, Teshamae Monteith, MD, FAAN, speaks with Nneka L. Ifejika, MD, MPH, author of the article "Social Determinants of Health and Their Impacts on Stroke Prevention and Outcomes" in the Continuum® June 2026 Cerebrovascular Disease issue. Dr. Monteith is the associate editor of Continuum® Audio and an associate professor of clinical neurology at the University of Miami Miller School of Medicine in Miami, Florida. Dr. Ifejika is an adjunct professor of physical medicine and rehabilitation at UT Southwestern Medical Center in Dallas, Texas, and the chief scientific officer of the Division of Academics at Ochsner Health System in New Orleans, Louisiana.

Dr Monteith: This is Dr. Teshamae Monteith. Today I'm interviewing Dr. Nneka Ifejika about her article on social determinants of health and their impacts on stroke prevention and outcomes. This article appears in the June 2026 Continuum issue on cerebrovascular disease. How are you? Welcome to our podcast. Dr Ifejika: Thanks for having me. I'm doing great. Dr Monteith: Great. So, can you introduce yourself to our audience? Dr Ifejika: Sure. I'm Dr. Nneka Ifejika. I am the Chief Scientific Officer of Ochsner Health System in New Orleans, Louisiana. But I'm also a cerebrovascular rehabilitation doctor. I've been practicing for about nineteen years, and am happy and honored to be a contributor to this Continuum Neurology article. It's a really important topic. Dr Monteith: Great. So, what got you into this field, first of all? Dr Ifejika: Well, I was deciding between PM&R and neurology, and I was putting in both match lists. And I thought about it and I leaned toward PM&R, but stroke still had a grasp on my heart and my mind. And so, after I finished my residency, I joined the UT Houston stroke team, and I did a, thankfully did a two-year fellowship and became cross-trained in stroke as well as physical medicine rehab. So, I am a jack of both trades. Dr Monteith: So, you got your way in a way. Dr Ifejika: I did. Dr Monteith: You know, we have a lot of learners that are listening, so it's always, uh, nice for them to be inspired, I think, by people's career paths. So why don't we talk about the objectives of your article? Dr Ifejika: Sure. So, one of the most important things that we wanted to do was make sure that medical students, residents, faculty, and fellows understood the impact of social determinants of health on stroke recovery and stroke rehabilitation. It's not as simple as you have hypertension, hyperlipidemia, we're going to manage your stroke risk factors. Oh, you had an ischemic stroke. You presented in time for the window. We're going to give you endovascular therapy and then modified Rankin scale at hospital discharge in ninety days. No, no, no. The stroke survivor and their caregivers and their family have a lot more to deal with outside of what we look at during the acute stroke hospitalization and post-acute rehabilitation. Things like, can they afford the medication that we're prescribing? Antiplatelet agents or anticoagulation can be extremely expensive. Do they have housing insecurity? Is there food insecurity? What's going on behind the scenes that we are not addressing that can directly impact the admission rate and the readmission rate after we take care of a stroke survivor? Dr Monteith: I love the article because you took a real deep dive into social determinants of health, what they are, why they matter, and what we can do about them. And so why don't we talk a little bit about the NINDS framework for social determinants of health? I think many of us might not be familiar with the framework per se. Dr Ifejika: So, the framework consists of multiple domains specifically that relate to social determinants of health that were published in Neurology a couple of years ago. So, I do hope that people who are hearing this recording actually read them. There are interpersonal domains, there are classic medical domains, there are indeterminate domains, and there are six total domains. And health domains are the last domain. So, things like when it comes to housing insecurity, food insecurity, that's a domain of social determinants of health. When it comes to chronic racism, when it comes to biases that patients experience, those actually impact outcomes. So, there are six separate indices that we're going to get into in detail and how we address them as clinicians, whether it be at the medical student level, resident level, faculty level, to integrate the social determinants of health in our care plans, because we could be doing a much better job. And I think it'll be really important from the interpersonal perspective when we really relate to our patients and their families that we ask these questions. For example, if we're prescribing someone to have treatment for their diabetes mellitus and ha- and, and be taking insulin, if they have housing insecurity and they're in a homeless shelter, they have to leave the homeless shelter during the day. So, what happens to the insulin that we prescribe? These are variables that we are not considering on a regular basis, but they directly relate to compliance. Dr Monteith: Great. So that was one thing I wanted to bring up. We're very good at measuring blood pressure and trying to determine, uh, the association between stroke outcomes and things that we can measure, glucose, lipids, blood pressure. What is the evidence for social determinants of health and stroke outcome? Dr Ifejika: The evidence is growing, and there have been many publications that have come out that are, are going to be highlighted in this article related to structural determinants of health inequities, like structural racism, as well as disparities related to ethnicity and race. There's geographical disparities. For example, a lot of patients are, are primarily concerned about rural versus urban, whether you have access to different post-acute rehabilitation, whether you have access to secondary stroke prevention because you simply don't have the transportation from a, a rural area to get to a drugstore to get things available to you. Social status. There are actually publication related to socioeconomic status and the concerns when it comes to air pollution. So particulate matter 2.5, we know that that has a direct impact on stroke outcomes and health overall, but we don't really think about it as a structural determinant of health inequity. There's several multiple layers of research that have gone on specifically that have been cited in the literature that relate directly to social determinants of health and how we can address them moving forward. Dr Monteith: And what I found interesting in your article in that you gave at least a few examples where social factors like income, education were controlled for, and maybe in large part it is, but even when you control for some of these very obvious social risk factors, you still have inequities. Dr Ifejika: Absolutely. And I think it was really important to show that we had strong peer review evidence behind this, as it wasn't just something that we were creating or hypothesizing about. There have been studies that have been done over this over decades of time, showing the impacts of social determinants of health on outcomes. But the question and concern that we have is we know this growing body of literature continues to expand. What are we doing about it when it comes to education of the future generations of providers who will be caring for this population? Dr Monteith: Before we get into how, you know, what we're going to do about that, let's just kind of put that link, cause the evidence is there. How does it drive biology? Dr Ifejika: It's a great question. So, for example, particulate matter 2.5 in air pollution has been shown to have an existing impact on hypertension, raising your blood pressure. So that's a direct effect of a social determinant of health related to socioeconomic status because people who live in areas with higher air pollution are... They're not green spaces. They live near highways. Those are areas that unfortunately are also impacted by food deserts. Food deserts, if you're not able to get fresh fruits, vegetables, whole foods, increases your risk of developing diabe

But what do we have to learn about preventing them altogether? The science of stroke prevention, acute treatment, and recovery are evolving rapidly, and it's hard to keep up. Today, we're speaking with Dr. Cheryl Bushnell, guest editor of our latest Continuum issue on Cerebrovascular Disease, to discuss these topics and much more.  Dr Jones: This is Dr. Lyell Jones, editor-in-chief of Continuum. Thank you for listening to Continuum Audio. Be sure to visit the links in the episode notes for information about subscribing to the journal, listening to verbatim recordings of the articles, and exclusive access to interviews not featured on the podcast.  Dr Jones: This is Dr. Lyell Jones, editor-in-chief of Continuum: Lifelong Learning in Neurology. Today, I'm interviewing Dr. Cheryl Bushnell, who is Continuum's guest editor for our latest issue on Cerebrovascular Disease. Dr. Bushnell is a professor of neurology and the director of the Center for Transformative Stroke Care at the Wake Forest University School of Medicine in Winston-Salem, North Carolina, where she specializes in the care of stroke patients and their social and functional determinants of recovery and health, and is an internationally recognized expert on those topics. Dr. Bushnell, welcome. Thank you for joining us today. Why don't you introduce yourself to our listeners?  Dr Bushnell: Absolutely. Thank you for the invitation. It's really an honor to be here. So, as you mentioned, I am the director of the Center for Transformative Stroke Care at Wake Forest. It's a really fun transition for me to be involved with different care models for stroke, and I think a lot of the Continuum topics are directly relevant to some of the things that I'm doing now as an administrator and sort of a facilitator of new research. So, thanks again for having me.  Dr Jones: Yeah, and, and you have a wonderful perspective, and we're gonna pull that out today in our interview questions, and I'm looking forward to sharing that with our listeners. But before we get to the questions, we're gonna start off today's podcast with another Continuum Audio trivia question for our listeners. Anticoagulation has played a critical role in secondary ischemic stroke prevention for a long time now. While direct oral anticoagulants have taken on a greater role in the treatment of prevention of stroke, there are still some use cases for vitamin K antagonists like warfarin. The trivia question for our listeners is this: How was warfarin discovered, and how did it get its name? Stick around and we'll share the answer to that question toward the end of our interview today. So, Dr. Bushnell, let's get right to it. You alluded to your various roles, and your leadership in the field has been exemplary. The interventions for acute ischemic stroke have really exploded over the last decade or so, and they get a lot of attention and discussion, but prevention and recovery are just as important in the care of these patients. Tell us a little more about how you approached this issue, about the article topics you chose, etc.  Dr Bushnell: Well, once I was chosen to lead the guest editorship, I wanted to come up with a group of topics that were maybe a little bit different from previous issues. So, I kind of looked at the previous issues and saw, as you said, an emphasis on acute stroke, and that's really important because it has been evolving. But my thought was, how about what happens to patients after they get the intervention and they're discharged home? And because a lot of trainees may not get to see these patients ever again, or it's months before they might see them, or if they're readmitted, which is what we don't want to see, but that certainly is a lot of the exposure is in the inpatient setting. So, I thought I would kind of transport the education into the outpatient and transitional setting, as well as prevention, not only secondary, but primary prevention, with an emphasis on brain health. Some of the populations that may not get as much attention. So, sex differences, stroke in women, pregnancy, the transitions of care, and also the emphasis on holistic view of patients and their challenges, which includes the non-medical factors that drive health, otherwise known as social determinants of health.  Dr Jones: I appreciate that perspective, and obviously th-this is an area of your deep expertise, and it's great to have an issue that really digs into some of those topics a little more deeply. As an educator, I'm really glad you mentioned that about the trainee's perspective. You know, especially junior neurology trainees that are in the hospital all the time. They're seeing patients in the middle of a cerebrovascular catastrophe. But there's a long tail of recovery, right? And they'll get to see that in continuity clinic, but it's a good message to share from an evidence and, um, experiential perspective in the issue. So, appreciate that perspective. You've just read all these articles and edited them. Was there anything that you ran across that was a surprise to you?  Dr Bushnell: Well, I personally chose a lot of the authors based on my knowledge of their work. So, I wouldn't say that it was completely surprising, but I do think that I was just genuinely impressed with the quality of the writing and the synthesis of information. I just was incredibly proud of the work that these co-authors have put together. I'd say that that was-- it wasn't surprising so much as just a sense of pride that I had with the product that's coming out. But of course, there have been some new trials that had to be incorporated at the last minute, some of which were presented at the International Stroke Conference just a few weeks ago.  Dr Jones: Yeah. We try to be as up-to-date as we can, and I will completely agree with you. We have some really good writers in our field, and it's really just a pleasure when you read an article that's by an expert, and it's a joy to read. I can tell you it's one of the best parts of this job, and you get to learn a lot. I think one of the more challenging scenarios that I hear about from colleagues in recent years has been optimal management of patients with asymptomatic extracranial atherosclerosis. The pivotal trials that inform how we manage those patients were from a long time ago, decades ago, predating a lot of the more intensive medical management tools that we have today. In that scenario, Dr. Bushnell, what's the latest on that, and what should our listeners know?  Dr Bushnell: Well, obviously, the CREST 2 trial has been long awaited. It's been going on for over ten years, I believe. Of course, it's, uh, two different trials all in one, the carotid stenting and angioplasty versus intensive medical management. And of course, each of the carotid vascularization arms of the trial also had intensive medical management. And then the other trial is the carotid endarterectomy as the form of revascularization. And it interestingly did not show any benefit of carotid endarterectomy compared to intensive medical management. But of course, the somewhat surprising result was that carotid angioplasty and stenting truly was superior, although it was a small number of events in the trial overall. But that stenting plus intensive medical management was somewhat better than intensive medical management alone. And I think stenting has come a long way in terms of safety, and so I think that's been part of the evolution of the field. I do wanna say that I'm a huge fan of the intensive medical management, and I think that what the protocol does in terms of blood pressure management, cholesterol management is very much above and beyond what's done in private practice even. And the health coaching for all the other things related to diabetes and weight loss and smoking cessation and physical activity, that is what we need to be doing to actually decrease the risk of stroke, and I think that it's very effective. I can't say enough about the design of the study for that reason, that everyone gets the intensive medical management, and then you just layer on the type of revascularization on top of it. So, I wouldn't have been surprised if this was a completely negative trial overall. They just happened to have some better outcomes in the stenting arm.  Dr Jones: I recall a few years ago when the series of endovascular therapy trials for acute stroke came out, and I think there was a, a period of time where the field had to adapt to that. I wonder what you think about with the CREST 2 findings on stenting. I mean, is that gonna be a big change? Because obviously atherosclerosis is highly prevalent. Is that gonna be a big change? Is the field ready for that? How much adjustment do we have in store?  Dr Bushnell: I'm not sure it's gonna be a really big change. If you read th
