Poor sleep in middle age could affect the brain in a surprising way, study finds

In a new study led by University of California, San Francisco, poor sleep was linked to faster brain aging in middle-aged adults. Researchers and doctors weigh in on the risk and how to reduce it.......                    ...                        ...There are some obvious signs of a You are not allowed to view links.

Register or Login......When evaluating sleep quality, the researchers looked at six poor sleep characteristics: short sleep duration, bad sleep quality, difficulty falling asleep, difficulty staying asleep, early morning awakening and daytime sleepiness.......Middle-aged participants with two to three poor sleep characteristics had a brain age that was 1.6 years older than those with no more than one poor sleep characteristic, according to Cavaillès.......Those with more than three poor sleep characteristics exhibited a brain age of 2.6 years older. ......The findings were published in Neurology, the medical journal of the American Academy of Neurology......."These findings are critical because they demonstrate that the link between sleep disturbances and brain health extends beyond older adulthood, suggesting that poor sleep in early midlife may already contribute to accelerated brain aging," he said.......Advanced brain aging is associated with cognitive decline and You are not allowed to view links.
