“Elite sleeper” gene study offers hope for novel dementia treatment

Posted on by

New research indicates people with the ability to sleep as little as four hours a night and remain healthy may harbor gene variants that can slow neurodegeneration

Are you one of those lucky people who seem to be able to thrive on between four and six hours of sleep per night? You may be what UC San Francisco researchers have dubbed an “elite sleeper,” and a new study reports the same genes associated with healthy short sleep patterns may also slow the onset of neurodegenerative diseases such as Alzheimer’s.
