Stephen: Excessive napping could be sign of Alzheimer’s, study suggests

New findings published Monday say that people who find themselves dozing off during the day, may be more at risk for Alzheimer’s disease, UPI reports. The study, published in the journal Alzheimer’s and Dementia, revealed that parts of the brain related to wakefulness are damaged in the early stages of Alzheimer’s, which is why people with the disease often start taking long naps even before the memory-robbing symptoms of the disease appear. Researchers also noted the role a protein called tau has in making Alzheimer’s patients feel sleepy during the day. Tau buildup was found to cause significant damage to areas of the brain related to daytime wakefulness. The findings suggest that excessive daytime napping could be an early symptom of the disease. Study author Dr. Lea Grinberg notes that the “research adds to a growing body of work showing that tau burden is likely a direct driver of [mental] decline.”
