Taking a frequent or prolonged nap during the day can be a sign of Alzheimer’s or dementia, reveals an American study published on Thursday.
Older people who took at least one nap a day or more than an hour were 40% more likely to develop Alzheimer’s disease than those who did not nap or nap less.
The study was published this Thursday in the publication “Alzheimer’s Disease Journal“. The data was collected over 14 years by the “Memory and Aging Projectto more than 1,400 people between the ages of 74 and 88. For 14 days a year, participants wore a device that tracked their movements.
“I think people haven’t realized yet that Alzheimer’s disease is a brain disease that often causes changes in mood and sleep quality,” said Richard Isaacson, director of Schmidt College of Medicine in Florida Atlantic University.
“Sleeping too many hours during the day could be one of many clues to possible cognitive decline,” he added.
Napping increased by an average of 11 minutes per year for adults who did not develop suspicious behavior. However, people diagnosed with Alzheimer’s nearly tripled their nap time to an average of 68 minutes a day.
“We found that the association between excessive naps and dementia persisted after sleep adjustment,” said one of the study authors, Yue Leng, a physician and assistant professor at the University of California.
In another study, Leg concluded that those who slept two hours a day had an increased risk of cognitive impairment compared to those who slept less than 30 minutes.
What to do?
Adults should limit daily naps to 15-20 minutes before 3:00 p.m. for more restful sleep that doesn’t disrupt nighttime sleep. Caregivers of people with Alzheimer’s disease should be aware of these people’s daily naps.
In addition, a significant increase in the number and duration of naps should be discussed with a doctor. Prioritizing sleep is also part of Dr. Richard Isaacson’s advice.
