Image via Wikipedia University of California Irvine researchers have identified a novel mechanism in the brain that boosts memory. In collaboration with scientists at Germany’s University of Munster, the UCI team found that a small protein called neuropeptide S can strengthen and prolong memories of everything from negative events to simple objects.

A new study shows that a sleep disorder may be a sign of dementia or Parkinson’s disease up to 50 years before the disorders are diagnosed. The research was published in the July 28, 2010, online issue of Neurology, the journal of the American Academy of Neurology. Using Mayo Clinic records, researchers identified 27 people [...]
Metabolic disorders such as obesity and diabetes appear to share risk factors with and may influence the development of Alzheimer’s disease and other forms of dementia, according to several reports published in the March 2009 issue of Archives of Neurology, one of the JAMA/Archives journals.
Women with the cluster of cardiovascular risk factors known collectively as the metabolic syndrome appear likely to develop cognitive impairment over a four-year period. Kristine Yaffe, M.D., of the University of California, San Francisco, and the San Francisco Veterans’ Affairs Medical Center, and colleagues assessed 4,895 older women (average age 66.2) who did not have cognitive impairment at the beginning of the study.
Continuous positive airway pressure (CPAP) treatment seems to improve cognitive functioning in patients with Alzheimer’s disease who also suffer from obstructive sleep apnea, according to the results of a randomized clinical trial conducted at the University of California, San Diego.
The study led by Sonia Ancoli-Israel, Ph.D., professor of psychiatry at the University of California San Diego School of Medicine and one of the nation’s preeminent experts in the field of sleep disorders and sleep research in aging populations was published in the November 2008 issue of the Journal of the American Geriatrics Society.
Snorers may be sending their partners to an early grave by pushing up their blood pressure, according to a new study.
Scientists have found that blood pressure increases in response to noises at night, whether you are awake or asleep.
Mayo Clinic researchers and a group of international collaborators have discovered a correlation between an extreme form of sleep disorder and eventual onset of parkinsonism or dementia. The findings appear in the current issue of the journal Brain.
Clinical observations and pathology studies, as well as research in animal models, led to the findings that patients with the violent rapid eye movement sleep (REM) behavior disorder (RBD) have a high probability of later developing Lewy body dementia, Parkinson’s disease or multiple system atrophy (a Parkinson’s-like disorder), because all of these conditions appear to stem from a similar neurodegenerative origin.

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.
