The less older adults sleep, the faster their brains age

Researchers have found evidence that the less older adults sleep, the faster their brains age. These findings, relevant in the context of a rapidly ageing society, pave the way for future work on sleep loss and its contribution to cognitive decline, including dementia.

"Our findings relate short sleep to a marker of brain aging," said Dr June Lo, the lead author and a Duke-NUS Research Fellow. "Work done elsewhere suggests that seven hours a day(2) for adults seems to be the sweet spot for optimal performance on computer based cognitive tests. In coming years we hope to determine what's good for cardio-metabolic and long term brain health too," added Professor Michael Chee, senior author and Director of the Centre for Cognitive Neuroscience at Duke-NUS.
