Irregular circadian rhythm in older adults associated with increased risk of Parkinson's disease

Older men who have a weak or irregular circadian rhythm guiding their daily cycles of rest and activity are more likely to later develop Parkinson's disease, according to a new study by scientists at the UC San Francisco Weill Institute for Neurosciences who analyzed 11 years of data for nearly 3,000 independently living older men.
