Brain responds same to acute & chronic sleep loss

Burning the candle at both ends for a week may take an even bigger toll than you thought. Researchers at the University of Wisconsin-Madison have found that five nights of restricted sleep – four hours a night — affect the brain in a way similar to that seen after acute total sleep deprivation.

Apnea therapy helps cognition in Alzheimer’s patients

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.

Primary snoring in children impacts cardiovascular functioning

Primary snoring in children may have an impact on cardiovascular functioning equivalent to that of moderate obstructive sleep apnea, according to a research abstract.

The study, authored by Angela Jackman and colleagues at the University of Melbourne and Monash University, Melbourne, Victoria, Australia, focused on 40 children who were referred for clinical assessment of a sleep-related breathing disorder and matched controls.

Sleep deprivation affects ability to make sense of what we see

Neuroscience researchers at the Duke-NUS Graduate Medical School, located in Singapore, have shown for the first time what happens to the visual perceptions of healthy but sleep-deprived volunteers who fight to stay awake, like people who try to drive through the night.

This study has implications for a whole range of people who have to struggle through night work, from truckers to on-call doctors.

CPAP use may boost apneics’ memory

A study recently published demonstrates that individuals diagnosed with obstructive sleep apnea (OSA) may have hope of regaining cognitive functions once they begin treatment for the apnea.

Study results, published in the December 2006 issue of CHEST, show the majority of trial participants who suffered memory-impairment prior to treatment demonstrated normal memory performance after three months of optimal continuous positive airway pressure CPAP use.

A CPAP is a medical device, which, in the simplest of terms, is an air generator set to deliver a prescribed, constant flow of air, keeping the airway open and preventing apnea.

Research questions use of sleep meds for apneics

Prescription sleep aids may do little to improve the use of continuous positive airway pressure devices (CPAP) among patients with obstructive sleep apnea (OSA).

A new study published in the November issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians (ACCP), finds that patients with OSA who were given prescription sleep aids were no more likely to use their CPAP machines than patients with obstructive sleep apnea taking a placebo.

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.
