Sleep Technology

Circadian rhythm sleep disorders (CRSDs) are neurological disorders in which the sleep-wake cycle is out of sync with the day-night cycle. This article focus on three: delayed sleep phase disorder, advanced sleep phase disorder and non-24-hour sleep-wake disorder.

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.

There are few things as frustrating in the sleep lab as a patient who can’t — or won’t — sleep. Barring the use of a sleeping pill, how can this situation be avoided? Consider the role of cognitive behavioral therapy for insomnia (CBTI) techniques and how these may ease insomnia during an overnight sleep study.

An overlooked symptom in people with obstructive sleep apnea (OSA) is olfactory dysfunction (i.e., impairment in the sense of smell) such as an inability to detect or distinguish between odors. A finding that the sense of smell improves soon after a person with OSA begins continuous positive airway pressure (CPAP) treatment corroborates a possible link between olfactory dysfunction and OSA.

This is the fourth article in a series on the changing face of sleep technology. The past three articles focused on technology and the economy. This article focuses on how all these changes could directly impact the future sleep technologist.

As a graduate student at the University of Chicago, I had the distinct pleasure to work with Allan Rechtschaffen. He famously said, “If sleep doesn’t serve an absolutely vital function, it is the biggest mistake evolution ever made.” But he was pessimistic that his research in sleep deprivation and the physiology of sleep would ever find that function.

I’m a big fan of Sleep Review. It’s a good way to keep up with all things sleep related like technology developments, business prospects and scientific advances. It’s attractive and well-written. But a recent headline sent me into full-out grumpy old man mode.
