Trauma Associated Sleep Disorder: How PTSD Patients Might Be Suffering From This New, Proposed Parasomnia

By: Kate Jacobson
June 24th, 2021

While working at the Madigan Army Medical Center in Washington state, Vincent Mysliwiec, MD, FAASM, and his colleagues started to notice a unique phenomenon. Soldiers coming into the sleep lab were experiencing disruptive nocturnal behaviors and nightmares following traumatic experiences associated with their deployment. These symptoms which occurred frequently at home, would at times occur in the sleep lab where the patients would have REM without atonia (RWA) during polysomnography. It was odd — unlike other instances of PTSD-induced nightmares he had seen — and it made Mysliwiec think there was something more there. “It was definitely something distinct,” Mysliwiec said. “Everyone always goes, ‘That’s just PTSD.’ Yes, those with PTSD very frequently have nightmares, but nowhere in the PTSD criteria do they have disruptive nocturnal behaviors or dream reenactment.” Mysliwiec and his colleagues called the phenomenon “Trauma Associated Sleep Disorder” and classified it as a potential parasomnia. Their first paper on it was published in October 2014 in the Journal of Clinical Sleep Medicine. Since then, there are a growing number of clinicians and researchers finding evidence in their own labs that young soldiers, as well as veterans, might be experiencing something more intense than symptoms commonly associated with PTSD. Moreover, they believe further study of this proposed parasomnia could be a major preventative measure for long-term PTSD complications. “If you can actually say to a solider, veteran — or anyone suffering from traumatic exposure — that we have an established diagnostic criteria for the severe sleep disturbances you are experiencing, then you can begin to evaluate treatments for this disorder and prevent long[1]term adverse outcomes. We could potentially treat them for this potential parasomnia and improve their sleep and that of their bed partner.” he said. “It’s an important question — and we need researchers to develop the criteria.”

Parasomnias

September 17th, 2020

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.

Alzheimer’s Disease Biomarkers in Children With OSA

By: Regina Patrick, RPSGT, RST
June 20th, 2019

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.

Hypersomnolence at Sea, Part I

By: Reg Hackshaw, EDD
November 21st, 2018

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.

Bad News for Slugabeds

By: Richard Rosenberg, PhD
August 20th, 2018

  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.
