Sleep Technology

This blog is based off of the AAST 2019 Annual Meeting Session "Parasomnias." For more information on this session and other session recordings click here. From nightmares to sleepwalking to REM sleep behavior disorder (RBD), parasomnias can occur in many forms without the patient even knowing they are experiencing an event. For sleep professionals, it is imperative they can educate patients with parasomnias as these sleep disorders can have lasting and physically damaging effects.

The neurocognitive disorder Alzheimer’s disease affects an estimated 5 million Americans. Its prevalence is expected to triple by 2060. People affected by Alzheimer’s disease have increasing problems with memory, judgement and doing daily tasks of living as the disease progresses. Various studies have indicated that obstructive sleep apnea (OSA) is associated with an increased risk of developing Alzheimer’s disease and that people with OSA have increased levels of certain biomarkers (e.g., amyloid beta protein) associated with Alzheimer’s disease. Scientists have recently noted increased levels of biomarkers associated with Alzheimer’s disease in young children with OSA.

Sleepwalking, yelling in your sleep, violently thrashing in bed and hurting those you love. No, it’s not a demonic possession; it is REM sleep behavior disorder, or RBD. RBD is a sleep disorder that common presents itself in older men and causes people who suffer from it to physically act out their dreams. Its cause is unknown, but its effects can be terrifying.

On Feb. 20 and 21, the National Safety Council (NSC) presented its first annual Workplace Fatigue Conference. It convened a diverse cross-section of leaders in the field of workplace fatigue management.

What does a German fairytale and a severe sleep disorder have in common? A lot, apparently.

Drowsy watchkeepers on vessels navigating open waters can be a major hazard during military and commercial shipping operations. The sinking of the H.M.S. Bonetta, a 19th century British warship, was a dramatic example of human error related to hypersomnolence at sea (HSS). The consequences resulting from a sailor who fell asleep during his shift on the ship’s bridge are preserved in a historical account. This article surveys the significance of HSS based on the  findings of an extensive research study and subsequently highlights events surrounding the loss of the Bonetta. Reviews of subjective scales used to identify HSS, and a computer application that estimates likelihood of drowsiness during the night shift, conclude this two-part series.

  Mary McKinley, R. EEG T., RPSGT, MA, is presenting the breakout session “Complementary and Integrative Therapies for the Management of Insomnia in Chronic Disease” at the AAST 2018 Annual Meeting, Sept. 28-30, 2018, in Indianapolis. We caught up with McKinley to discuss her background and the future of sleep medicine.

  I was a postdoctoral fellow at Argonne National Laboratory and had the pleasure of working with George Sacher. At the time, he was president of the Gerontological Society of America and had spent his life working on ways to increase lifespan. He was a proponent of hormesis, the idea that moderation was the path to a longer life. Of course, some things should be off the list, like a moderate amount of murder. 

The advent of actigraphy in the 1990s made it possible to indirectly record a person’s sleep-wake cycles based on the person’s activity level, with increased activity indicating wakefulness and decreased activity indicating sleep. In actigraphy, a device — an actigraph — which is typically worn on the wrist, continually records movement data over a prolonged time — one week or more. 

Every healthcare professional walks into the examination room with predetermined biases regarding the patients they see. Fifty-year-old obese man? OSA, of course. Twenty-year-old woman with daytime sleepiness? Could be narcolepsy. A man comes to the sleep center with his wife and she has a black eye? REM behavior disorder (RBD) is suddenly on your radar.
