    Repurposing Medications to Slow Progression of PD

    Repurposing Medications to Slow Progression of PD

    Until the ultimate goal of finding a cure for Parkinson’s disease (PD) is achieved, researchers are taking various approaches to developing a treatment that significantly slows its progression. Here, clinical science and basic science come together to understand the underlying biological mechanisms of PD and then using that knowledge to test medications that target those mechanisms. Having discovered such molecular and cellular malfunctions, scientists may tailor the development of medications to target the underlying causes of the disease.
     
    Another approach has also relied on knowing the mechanisms of the disease but then searching through the vast array of current drugs to treat all sorts of conditions and rationally choosing ones that may work to slow progression of PD – so-called drug repurposing. Dr. Patrik Brundin, Director of the Parkinson’s Disease Center at Van Andel Institute in Grand Rapids, Michigan, explains that this is the approach that the International Linked Clinical Trials (iLCT) program for Parkinson’s has taken. Since its inception in 2010, the iLCT has become one of the most comprehensive drug repurposing programs focused on a single disease. Under this program, seven clinical trials have been completed, and 15 are ongoing, testing 16 potential candidate drugs to slow the progression of PD. The advantage is that the drugs under consideration have already been tested for safety and how they act in the body, speeding up the process of applying them to Parkinson’s.

    Gene-Based Therapies for Parkinson’s Disease

    Gene-Based Therapies for Parkinson’s Disease

    Gene-based therapies for Parkinson’s disease, while still in the developmental stage, are under active investigation. For this potential therapy, genes are engineered in a laboratory and then injected into specific parts of the brain. The genes may function either to induce cells in the brain to produce dopamine, or to code for the production of enzymes that then lead to the production of dopamine.
     
    This episode is the second part of our conversation with Dr. Roger Barker, Professor of Clinical Neuroscience at the University of Cambridge in the United Kingdom. In our previous podcast with him, he discussed cell therapy for Parkinson’s. Here, he explains what gene-based therapy is, plans for the execution of the treatments, what symptoms they are aimed at, where the field currently stands, and how it compares to developments in cell-based therapies. As the field is still in the experimental stages, he again offers advice to people with Parkinson’s who are considering entering a clinical trial of gene-based or cell-based therapy and what they may expect in terms of symptom management and disease progression.

    Cell-Based Therapies for Parkinson’s Disease

    Cell-Based Therapies for Parkinson’s Disease

    Researchers have been investigating cell-based therapies for treating Parkinson’s disease (PD) for some time now, using a variety of materials and methods. Two approaches have been to implant dopamine-producing cells or to induce cells already in the brain to become dopamine-producers. We asked Dr. Roger Barker, Professor of Clinical Neuroscience at the University of Cambridge in the United Kingdom, to summarize what has been learned so far and based on that, to give his perspective on where the field may be headed. The field is still in the experimental stages, and he cautions about what people with PD should ask when considering entering a clinical trial of cell-based therapy and what they may expect in terms of symptom management and disease progression.

    Non-pharmaceutical Treatments for PD: DBS and Focused Ultrasound

    Non-pharmaceutical Treatments for PD: DBS and Focused Ultrasound

    Not all medical interventions for Parkinson’s disease (PD) involve drugs. Two other main treatments are deep brain stimulation (DBS) and focused ultrasound (FUS). DBS uses a surgically implanted electrical pulse generator connected to electrodes placed in the brain to stimulate areas involved in PD. FUS does not require surgery but aims ultrasound –  high frequency sound waves – at a specific area of the brain to relieve Parkinson’s symptoms.
     
    Each technology has its uses, advantages, and disadvantages. In this podcast episode, Kyle Mitchell, MD of Duke University in North Carolina discusses the two treatments, how each works, which patients may do best with either of them, and some caveats. He also looks ahead at what is in development.

    Alone in a Crowd: Overcoming Isolation

    Alone in a Crowd: Overcoming Isolation

    Social isolation may affect many people as they age, and COVID has exacerbated the problem for everyone. Isolation can have negative effects on physical as well as mental health. People with Parkinson’s disease (PD) are especially at risk for social isolation because of progressive physical changes, mood disturbances, a shrinking social circle, and secluding oneself due to fear of how people may perceive them. Apathy is also a common non-motor symptom, affecting people with Parkinson’s and making it difficult for them to get involved in activities. Other non-motor symptoms such as anxiety and depression can further limit social engagement.
     
    In this podcast episode, Aaron Daley, Coordinator for the Parkinson’s Disease Clinic and Research Center at the University of California, San Francisco, discusses social isolation and ways to overcome it, whether you live in an urban or rural area. He recommends seeking out support at the first sign of the problem, exercising regularly, or just establishing a routine of activity with a companion.

    Social Isolation and Loneliness

    Social Isolation and Loneliness

    Social isolation can have harmful effects on health and often increases with age because of loss of friends, acquaintances, or a spouse, hearing or vision deficits, or loss of mobility. In addition to being a risk factor for poor health, social isolation has been associated with an increased risk of death. Loneliness may lead to poor sleep and depression, two problems that already affect a proportion of people with Parkinson’s disease (PD). On top of all this, for more than a year social distancing to limit the spread of COVID-19 has added to problems of mental and physical health for many people.
     
    In the face of a lack of research on social isolation in PD, Dr. Indu Subramanian, Director of the Parkinson’s Disease Research, Education and Clinical Center at the West Los Angeles Veterans Affairs Medical Center, conducted a survey of people with Parkinson’s to see if social isolation is associated with the severity of their symptoms and with their quality of life.
     
    The survey was done before the pandemic. It showed that people reporting loneliness had 55% higher symptom severity, but individuals with a lot of friends had 21% fewer symptoms as compared with people reporting having few or no friends. (These are associations, and one should not assume a cause-and-effect relationship.) These results support the need for people with Parkinson’s to be socially engaged to prevent loneliness. In this podcast, Dr. Subramanian discusses loneliness and social isolation and offers suggestions for keeping them at bay.

Grouchy PD husband

Thank you for your very informative podcast. My husband was diagnosed 5 years ago. His mother also had Parkinsons but it was a very mild case. My question is this: Are mood changes common with this disease? My sweet, loving husband has turned into a grouchy complainer. I can’t seem to do anything right in his opinion. I look forward to your answer.

A wonderful way to get a diverse perspective and info on the many different facets of living with PD. or loving someone with PD.
