Study finds lack of sleep can lead to brain damage

Posted: Updated:
NEW YORK (MYFOXNY) -

A study conducted by researchers at Duke-NUS Graduate Medical School found that the less older adults sleep, the faster their brains age.

The study examined 66 Chinese adults aged 55 years and older in Singapore. 

The brains of the adults were scanned to measure brain volume and assess cognitive function. Sleep duration was recorded through a questionnaire and the evidence showed those who slept less had a decline in brain functionality.

Researchers concluded the decline in brain functionality could lead to dementia and suggest seven hours of sleep for adults. 

“Seven hours a day for adults seems to be the sweet spot for optimal performance based on cognitive tests,” said Dr. June Lo, the lead author and a research fellow at Duke-NUS.

The study was published in the journal SLEEP.
