Talking Sleep AASM

There are a handful of direct-to-consumer devices that claim to improve the quality of our sleep by using acoustic stimulation. What is the science behind these devices? Dr. Roneil Malkani is an associate professor of neurology in the Feinberg School of Medicine at Northwestern University. He collaborates with others to study acoustic stimulation during sleep and its impact on sleep architecture. He describes how these devices work and how clinicians should approach them.

While CPAP devices are similar across manufacturers, there are more significant differences in the advanced modalities of ventilatory support. Dr. Lisa Wolfe is well known for her granular knowledge of mechanical ventilation, including noninvasive ventilation (NIV). She discusses some aspects of NIV that may become pertinent as both sleep labs and patients transition off devices recalled by Philips Respironics. She also addresses concerns related to patients who have complex conditions such as chronic obstructive pulmonary disease (COPD), obesity hypoventilation syndrome, and neuromuscular disease.

We know that CBT-I is the gold standard treatment for insomnia, but it remains inaccessible for many due to cost or the limited availability of trained professionals. For patients with comorbid mental health disorders, insomnia treatment may improve their sleep and mental health, but sleep restriction therapy may not be the most appropriate modality. Dr. Chris Bojrab is a psychiatrist who has embraced sleep care as a vehicle to improve the mental health of his patients, and he has expertise in neurotransmitters. He discusses pharmacologic treatment of insomnia and some important considerations in those with mental health disorders.

While sleep disorders are associated with numerous health complications, one area that doesn’t receive much attention is the impact of sleep and sleep disorders on those with sickle cell anemia. A study published in Sleep and Breathing found that children with sickle cell disease and comorbid obstructive sleep apnea had 47% more health complications than those with sickle cell disease who had a lower risk for OSA due to negative OSA screenings or exams. These complications seemed to be related to nocturnal hypoxia. Pain from a sickle crisis also can lead to sleep fragmentation. Dr. Sonal Malhotra discusses the many ways in which she tries to optimize sleep for her patients with sickle cell anemia.

Johns Hopkins colleagues Dr. Rachel Salas and Dr. Sara Benjamin discuss the basics of treating restless legs syndrome (RLS), focusing on an updated algorithm published in the Mayo Clinic Proceedings in 2021 by the Scientific and Medical Advisory Board of the Restless Legs Syndrome Foundation. Topics of discussion include pharmacological treatment options, the risk of augmentation, potential impulsivity, and non-pharmacologic treatments.

We routinely see patients with dementia in our sleep clinics but often do not meet them until they present with a sleep complaint such as insomnia or obstructive sleep apnea. We know that sleep and dementia have a bidirectional relationship. Is there a way to identify those who are at higher risk of dementia and intervene earlier? Is there a polysomnographic fingerprint? Should polysomnography be performed in those who are felt to be at higher risk of dementia? How can we, as sleep clinicians, potentially impact the course of dementia? Are there special considerations for our patients who have dementia and a comorbid sleep disorder? Dr. Brendan Lucey help us explore these issues further.
