Sleep loss may be a sign of early Alzheimer

(March 11, 2013 - Insidermedicine)

From St. Louis – Sleep loss can be an early sign of Alzheimer’s disease, according to research published in JAMA Neurology. Researchers studied nearly 150 volunteers, aged 45-75 years old. All participants were cognitively normal at the outset of the study.

Results showed that 32 participants had preclinical Alzheimer’s disease—and that these individuals had much worse sleep efficiency than individuals without the Alzheimer’s markers.
