Sleep Apnea Common in Patients With Memory Problems by Angela Mohan on March 1, 2021 at 12:14 PM
Obstructive sleep apnea is found to be common in people with cognitive impairment, as per the study that will be presented at the American Academy of Neurology s 73rd Annual Meeting being held virtually April 17 to 22, 2021.
Cognitive impairment includes memory and thinking problems that affect concentration, decision making and learning new things. The risk of cognitive impairment increases as people age. Better sleep is beneficial to the brain and can improve cognitive skills. Yet in our study, we found that over half of the people with cognitive impairment had obstructive sleep apnea, said study author Mark I. Boulos, M.D., of the University of Toronto in Canada and member of the American Academy of Neurology.
Wanna Be Productive? Sleep for 6 Hours: Elon Musk by Hannah Joy on February 17, 2021 at 5:25 PM
Sleeping at least for six hours every night increases your total productivity, says Tesla and SpaceX CEO Elon Musk in a podcast.
In an episode of the podcast The Joe Rogan Experience Musk confessed that he tends to work a lot and even schedule meetings at one or two in the morning. I tried sleeping less, but then total productivity decreases. I don t find myself wanting more sleep than six (hours), he said.
‘Tesla employees told Business Insider in 2018, that they frequently see their boss asleep while curled under tables, desks, and even on the factory floor.’
Muscle Paralysis During Sleep
Narcolepsy (excessive daytime sleepiness), cataplexy (sudden loss of muscle tone), and rapid eye movement (REM) sleep behavior disorder are serious sleep-related disorders. The researchers have found neurons in the brain that link all three disorders and could provide a target for treatments.
The research led by Professor Takeshi Sakurai at the University of Tsukuba is published in the
Journal of Neuroscience.
Most of the dreams occur during REM sleep in which the eyes move back and forth, but our bodies remain still. This
near-paralysis of muscles while dreaming is called REM-atonia. In patients with REM sleep behavior disorder, REM-atonia is absent due to which the muscles move around often leading to stand up and jump, yell, or punch. Researchers have found neurons in the brain that normally prevent this type of behavior during REM sleep.
Sleep Disturbances may Contribute to Alzheimers Disease by Karishma Abhishek on December 17, 2020 at 1:02 PM
Sleep disturbances like fractured sleep and daytime sleepiness are the worsening complaints of people with Alzheimer s disease (AD), as the disease progresses. But the exact link between Alzheimer s and circadian dysfunction remains masked.
A brain protein - YKL-40 that is regulated by clock genes is also a well-known biomarker of Alzheimer s disease, involved in clearing away the toxic buildup of Alzheimer s protein plaques in the brain, as per a study at Washington University School of Medicine in St. Louis published in the journal Science Translational Medicine.
