Daytime sleepiness contribute to Alzheimer's disease - Study

Your daily sleeping habit would changed if you read the recent study about Alzheimer's disease.

According to a new study, those people who's very sleepy during day time were nearly three times more likely to have beta-amyloid deposits on their brain about 16 years later, according to study published in the journal sleep.

Adults who reported napping during the day were also slightly more likely to have beta-amyloid deposits on their brain.



The study published in journal Sleep, included 124 mentally healthy men and woman, average age 36-80 , who reported on their own daytime sleepiness and napping habits. An average of 15 years later, researchers administered PET and M.R.I. scans to detect the presence of beta-amyloid, the protein that clumps together to form plaques.

The study has revealed that poor quality sleep at nighttime could encourage this form of dementia, suggesting to improved nighttime sleep could be away to help prevent Alzheimer's disease. 

Diet and exercise have been widely recognized as important potential targets for Alzheimer's disease prevention, said Adam Spira in Science Daily, lead author and associates professor in the Department of Mental Health at the Johns Hopkins Bloomberg School of Public Health.

"If you're falling asleep when you'd rather be awake, that's something that needs to be investigated," Spira added.

The study started in 1958, with participants periodically filling out surveys about their sleeping habits and began brain imaging in 1994.

Alzheimer's is a progressive, neurodegenerative condition - is characterized by memory loss and cognitive impairments. Early warning signs include confusion regarding habitual tasks and severe changes to behavior.
