Sleep Deprivation Taxes Neurons, Racks Up Brain Amyloid-beta?

While the occasional all-nighter to cram for exams or finish a grant proposal may seem like no big deal, losing sleep night after night could take its toll on brain health in later life, two new studies suggest. Based on microdialysis experiments in live mice, Dave Holtzman, Washington University, St. Louis, Missouri, and colleagues report in the current issue of Science that extracellular amyloid-beta levels in the brain fall during slumber and rise with wakefulness.

Sleep Deprivation And Dementia

A study published in Science has found that levels of amyloid beta, a protein fragment associated with Alzheimers disease, rose and fell in association with sleep and wakefulness in mice. 'It is interesting that there may be a link between sleep and the build up of the protein associated with the development of Alzheimer's disease.

Increase In Alzheimer’s Plaques And Sleep Loss Linked

Chronic sleep deprivation in a mouse model of Alzheimer's disease makes Alzheimer's brain plaques appear earlier and more often, researchers at Washington University School of Medicine in St. Louis report online this week in Science Express. They also found that orexin, a protein that helps regulate the sleep cycle, appears to be directly involved in the increase. Neurodegenerative disorders like Alzheimer's disease and Parkinson's disease often disrupt sleep. Tags: Insomnia Sleeping problems Insomnia information Sleepin

Alzheimer’s Society Comment On Longer Sleep Duration Being Associated With An Increased Risk Of Dementia

Alzheimer’s Society Comment On Research Suggesting That Sleep Disorder May Be An Early Sign Of Dementia Or Parkinson’s Disease

People who act out their dreams through kicking and crying out in their sleep may go on to develop dementia or Parkinson's disease, according to a study published in the online issue of Neurology. In the research 93 people with REM sleep behaviour disorder who had no signs of a neurodegenerative disease were followed for an average of five years.

Sleep And Memory Problems In Elderly African-Americans Linked In Landmark Study

A landmark study led by North Carolina State University researchers shows that African-American seniors who have trouble falling asleep are at higher risk of having memory problems - raising the possibility that identifying and treating sleep difficulties in the elderly may help preserve their cognitive functioning. The study is the first to examine the link between sleep and cognitive functioning in older African-Americans. The study, led by NC State psychology Ph.D. Tags: Insomnia Sleeping problems Insomnia information Sleepin
