Schizophrenia could be revealed by distinctive sleep pattern
When people with schizophrenia sleep, their brain waves show a distinctive pattern that may someday lead to one of the first biological markers for this devastating mental illness.

Obstructive sleep apnea linked with later risk of heart disease
DALLAS, July 12, 2010 — Severe obstructive sleep apnea (OSA) raised the risk of heart failure for middle-aged and older men — and significantly raised the risk of coronary heart disease in men up to age 70, according to research reported in Circulation: Journal of the American Heart Association.
After adjusting for known heart risk factors, researchers found that men with the most severe OSA faced a 58 percent higher risk of developing heart failure than those without OSA. And those ages 40 to 70 with the most severe OSA had a 68 percent higher risk of developing coronary heart disease than those without OSA.
“The Sleep Heart Health Study is the first to demonstrate prospectively that sleep apnea is associated with an increased incidence of heart failure,” said Daniel J. Gottlieb, M.D., M.P.H., lead study author and associate professor at Boston University’s School of Medicine. “It’s also the first large community-based study specifically designed to examine the association of sleep apnea with either coronary heart disease or heart failure. Previous work has focused more narrowly on patients receiving care at sleep clinics.”
In obstructive sleep apnea, the airway collapses during sleep, leaving patients struggling to breathe.

Lack Of Deep Sleep May Increase Risk Of Type 2 Diabetes
ScienceDaily (2008-01-02) -- Suppression of slow-wave sleep in healthy young adults significantly decreases their ability to regulate blood-sugar levels and increases the risk of type 2 diabetes. This study found that after only three nights of selective slow-wave sleep suppression, young healthy subjects became less sensitive to insulin. ... > read full article
