Insomnia Research

A study in the May 1 issue of the journal Sleep is the first to examine sleep issues in a large sample of exceptionally old adults, including nearly 2,800 people who were 100 years of age and older. Results show that about 65 percent of the sample reported that their sleep quality was...

At 30 years old, male testosterone levels drop by one to two percent annually. By age 40, men's quality of sleep begins to diminish. Could there be a link between decreased testosterone and reduced sleep?

Sleep apnea may cause metabolic changes that increase insulin resistance, according to researchers from the University of Pittsburgh Medical Center. The intermittent hypoxia associated with sleep apnea causes a...

Sleeping consistently for less than six hours a night may cause an early death, but too much sleep could also mean problems, according to a study that claims to have found unequivocal evidence of the potential harm from abnormal sleep patterns.

Individuals with chronic insomnia have an elevated risk of death, according to a research abstract presented June 7, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Excessive sleepiness is more common in the U.S. than in Europe, which raises concerns for public health and safety, according to a research abstract presented June 8, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.

Scientists at The University of Manchester have solved a mystery connected with why people die from sudden cardiac arrest during sleep -- potentially saving thousands of lives.

In the initial stages of sleep, energy levels increase dramatically in brain regions found to be active during waking hours, according to new research in the June 30 issue of the Journal of Neuroscience. These results suggest that a surge of cellular energy may replenish brain processes needed to function normally while awake.

Drugs commonly taken for a variety of common medical conditions including insomnia, allergies, or incontinence negatively affect the brain causing long term cognitive impairment in older African-Americans, according to a study appearing in the July 13, 2010 print issue of Neurology, the medical journal of the American Academy of Neurology.
