Two New Studies Analyze Menopause-Related Sleep Problems
Two studies in the July 1 issue of the journal Sleep analyze menopausal sleep problems, finding that complaints may differ according to the stage of menopausal transition and the ethnicity of the woman, and identifying risk factors that may predict sleep problems at any stage of menopause. A multi-ethnic study of more than 3,000 women shows that the odds of having trouble falling asleep and staying asleep increase through the menopausal transition.

Study Provides Evidence Of Brain Damage In Adults With Obstructive Sleep Apnea
A study in the July 1 issue of the journal Sleep provides visual evidence of the severe structural damage that occurs in numerous regions of the brain in people with obstructive sleep apnea (OSA). Results show that OSA patients have extensive alterations in "white matter," nerve tissue in the brain containing fibers that are insulated with myelin - a white, fatty sheath.

Study Shows That Milder Forms Of Sleep-Disordered Breathing Are Associated With Hyperglycemia
A study in the July 1 issue of the journal Sleep shows that episodes of sleep-disordered breathing accompanied by mild oxygen desaturations of as little as two percent are associated with hyperglycemia. Adults with 11 or more apnea-hypopnea events per hour with an oxygen desaturation of 2.0 percent to 2.9 percent had an adjusted cumulative odds ratio of 1.41 for impaired fasting glucose or diabetes.
