Bruxism, the medical term for the grinding of teeth during sleep, is prevalent in Caucasians with sleep disorders, a study has found. There is a high prevalence of nocturnal teeth grinding, or bruxism, in patients with obstructive sleep apnea, particularly in Caucasians.
Loss of sleep, even for a few short hours during the night, can prompt one’s immune system to turn against healthy tissue and organs.
A new article in the September 15, 2008 issue of Biological Psychiatry, by the UCLA Cousins Center research team, reports that losing sleep for even part of one night can trigger the key cellular pathway that produces tissue-damaging inflammation. The findings suggest a good night’s sleep can ease the risk of both heart disease and autoimmune disorders such as rheumatoid arthritis.
Study results published in the September 1, 2008 issue of the journal Sleep shows that daytime sleeping during a rehabilitation stay predicts less functional recovery for older adults, with effects lasting as long as three months.
Results show that a higher percentage of daytime sleep during rehabilitation was significantly associated with less functional recovery from admission to discharge even after adjusting for other predictors such as mental status, hours of therapy received and reason for admission. More daytime sleeping during rehab remained a significant predictor of less functional recovery at a three-month follow-up.
People with obstructive sleep apnea have been reported to have increased markers of oxidative stress and exhibit architectural changes in their brain tissue in areas involved in learning and memory. Chronic intermittent hypoxia in rats produce similar neurological deficit patterns.
“Obstructive sleep apnea has been increasingly recognized as a serious and frequent health condition with potential long-term morbidities that include learning and psychological disabilities,” wrote David Gozal, M.D., professor and director of Kosair Children’s Hospital Research Institute at the University of Louisville, lead author of the article.

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.

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.
