A new study on sleep and brain aging in midlife, first-authored by Clemence Cavailles, PhD, has been published in Neurology. The study found that an increased number of poor sleep characteristics - such as bad sleep quality or difficulty initiating and maintaining sleep - in early midlife were associated with faster brain aging by late midlife. These findings emphasize the importance of sleep quality in midlife (as opposed to merely sleep quantity) and the impact of long-term exposure to poor sleep quality on the brain.
