For people with chronic insomnia, a good night's sleep is elusive. But what if insomnia symptoms could be alleviated by simply listening to one's own brainwaves? Researchers at Wake Forest Baptist Health conducted a clinical trial that showed reduced insomnia symptoms and improved autonomic nervous system function using a closed-loop, acoustic stimulation neurotechnology.

Researchers at Rensselaer Polytechnic Institute anticipate a future in which a combination of smart wearables and algorithms assess each person’s circadian rhythm and provide personalized feedback as to what light, sleep, and work schedule would be ideal for their particular internal clock. In a foundational step toward that goal, a team of engineers aims to develop reliable mathematical models that can estimate individuals’ circadian rhythms. With the support of a grant from the National Science Foundation (NSF), the team will also develop wearable hardware and software that incorporate various sensors capable of capturing useful biometric information. That data will be used to help build and test the team’s mathematical models.

As you drift into unconsciousness before a surgery, general anesthetic drugs flowing through your blood are putting you to sleep by binding mainly to a protein in the brain called the ɣ-aminobutyric acid type A (GABAA) receptor. Now UT Southwestern scientists have shown exactly how anesthetics attach to the GABAA receptor and alter its three-dimensional structure, and how the brain can tell the difference between anesthetics and the psychoactive drugs known as benzodiazepines – which also bind to the GABAA receptor. The findings were published online today in the journal Nature.

Getting more sleep, and establishing a regular sleep schedule, is a common recommendation for maintaining and improving health, including for people with Type 1 diabetes. Short sleep patterns may affect how the body uses insulin, and irregular sleep schedules can affect glucose through changes in one's circadian rhythm or biological clock.

Disturbed sleep patterns do not cause Alzheimer’s disease but people who are at high genetic risk of developing Alzheimer’s disease may be more likely to be a “morning person,” have shorter sleep duration and other measures of sleep disturbance and are less likely to have insomnia. The study is published in the August 19, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
