Research on the sleeping brain has revealed some fascinating stage-dependent interactions between areas involved in formation and storage of long term memories. The study, published by in the the journal Neuron, may also provide a framework for further understanding the role of sleep in memory.
Mammalian sleep occurs in two discrete stages, slow-wave sleep (SWS) and rapid eye movement (REM) sleep. One of the many ways in which SWS and REM sleep differ is in the level of synchronous firing in the hippocampus. Previous research has suggested that coordinated activity between the hippocampus?a brain area critical for memory formation where long-term memories are stored?—?may be critical for memory formation.

Rapid eye movement sleep behavior disorder (RBD) appears to be a predictor of neurodegenerative disease in more than 50 percent of cases, according to a recent study
According to the latest study by Dr. Ronald Postuma, of the Research Institute of the MUHC, and Dr. Jacques Montplaisir, of the Université de Montréal and the Hospital of the Sacred Heart of Montreal, 52.4 per cent of patients with Rapid eye movement sleep (REM) sleep behavior disorder develop a neurodegenerative disease within 12 years following their initial diagnosis.

Children and teens who get less sleep, especially those who spend less time in rapid eye movement (REM) sleep, may be more likely to be overweight, according to a report in the Archives of General Psychiatry.
The obesity rate has more than tripled among children six-to-11 years in the past 30 years, and approximately 17 percent of U.S. adolescents are now overweight or obese, according to background information in the article.

Research engineers and sleep medicine specialists from two Michigan universities have joined technical and clinical hands to put innovative quantitative analysis, signal-processing technology and computer algorithms to work in the sleep lab. One of their recent findings is that a new approach to analyzing sleep fragmentation appears to distinguish fibromyalgia patients from healthy controls.
Joseph W. Burns, a research scientist and engineer at the Michigan Tech Research Institute (MTRI); Ronald D. Chervin, director of the University of Michigan’s Michael S. Aldrich Sleep Disorders Laboratory; and Leslie Crofford, director of the Center for the Advancement of Women’s Health at the University of Kentucky, report the results of their study in the August 2008 issue of the journal Sleep Medicine.

Treating pediatric obstructive sleep apnea (OSA) with either orthodontic expansion or adenotonsillectomy improves symptoms, but most young children need both treatments to have complete resolution of OSA symptoms, according to a study published in the July 1, 2008 issue of the journal Sleep.

Children with a migraine headache are more likely to have sleep disorders, such as obstructive sleep apnea and lack of sleep, than children without a migraine, according to a research abstract on the effects of headaches on children’s sleep patterns at Sleep 2008.
For this study, 90 children with headache and sleep problems underwent a polysomnogram, a sleep test that monitors the brain, eye movements, muscle activity, heart rhythm, and breathing. Of the participants, 60 had a migraine, 11 had a chronic daily headache, six had a tension headache and 13 had a non-specific headache.

There is new promise on the horizon for those who suffer from REM Sleep Behavior Disorder (RBD), according to researchers at the University of Toronto.
RDB, a neurological disorder that causes violent twitches and muscle contractions during rapid eye-movement (REM) sleep, can lead to serious injuries.

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.

Interesting Apnea Statistics
~~ Apnea in United States ~~
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.
~~ Apnea around the world ~~
As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the world population
was 6,777,286,604. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 474,410,062 apneics in the world.
