Day-dozing may sign Alzheimer’s disease, as it may lead to develop harmful plaque in the brain known as beta-amyloid – accumulation of a protein, especially in the cases older adults, as researchers just found.

Earlier researches have been indicating that a poor sleep is associated with a major risk of dementia, but the latest research disclosed in the JAMA Neurology – medical journal suggests that excessive drowsiness during the daytime mainly in cognitively normal older people may be promoting buildup of an amyloid plaque.

Director at the Alzheimer’s Prevention Clinic at the New York-Presbyterian / Weill Cor- nell Medical Center, Dr. Richard Isaacson said in a statement that, “While further research is necessary, this study adds a new question that doctors can ask patients to assess risk and potentially intervene. In fact, the findings will change the way i care for patients, as I will now proactively ask about excessive daytime sleepiness as one of the many potentially modifiable risk factors for the disease.”

However, the research released by the journal Brain last year, discovered that healthier middle-aged people having poor sleep just for a night developed a profusion of beta-amyloid, as a leading author of the published study, Dr. Yo-El Ju said, who is an assistant neurology professor from the Sleep Medicine Center at the Washington University.

Bryce Mander, assistant professor of human behavior and psychiatry from the University of California, Irvine School of Medicine, said that, “These findings, however, further support the idea that sleep is critical for mental health, and that chronically disturbed sleep may facilitate the development of Alzheimer’s disease or accelerate its progression.”
