A new study finds older adults who received positive airway pressure therapy prescribed for obstructive sleep apnea may be less likely to develop Alzheimer's disease and other kinds of dementia. Researchers from Michigan Medicine's Sleep Disorders Centers analyzed Medicare claims of more than 50,000 Medicare beneficiaries ages 65 and older who had been diagnosed with […]
A new Northwestern University study provides the first evidence that infants’ increasingly precise perceptual tuning to the sounds of their native language sets constraints on the range of human languages they will link to cognition. According to the researchers, this reveals that as early as 3 to 4 months, infants’ advances in speech processing play […]
Even among sleep researchers, it is a widely held belief that sleep quality can be improved by avoiding exercise in the evening. However, as researchers from the Institute of Human Movement Sciences and Sport at ETH Zurich have demonstrated, it is not generally true. The scientists combed through the literature on the subject and analysed […]
Sleep disruptions are associated with many brain disorders, including anxiety, dementias, and traumatic brain injury. While these disruptions are sometimes viewed as a side effect of brain disorders, new findings presented today suggest that aberrant sleep-wake cycles can also drive brain pathology. The studies were presented at Neuroscience 2018, the annual meeting of the Society […]
Researchers at Michigan State University conducted the largest experimentally controlled study on sleep deprivation to date, revealing just how detrimental operating without sleep can be in everything from bakers adding too much salt to cookies to surgeons botching surgeries. While sleep deprivation research isn’t new, the level at which distractions hinder sleep-deprived persons’ memories and […]
Some patterns of electrical activity generated by the brain during sleep are inherited, according to a study of teenage twins published in JNeurosci. Pinpointing the relative contributions of biology and experience to sleep neurophysiology could inform therapies for numerous psychiatric disorders in which alterations in brain activity during sleep can be detected. Leila Tarokh and […]
Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But it’s not just an issue of logging at least seven hours of Z’s. A new study on sleep patterns suggests that a regular bedtime and wake time are just as important for heart and metabolic health among older adults. […]
Biological markers responsible for extreme exhaustion in patients with cancer have now been linked to fatigue in those with Parkinson’s disease, according to new research from Rice University. “Inflammation and fatigue in early, untreated Parkinson’s disease” will appear in an upcoming edition of Acta Neurologica Scandinavica. It is one of the first studies to link […]
