Circadian abnormalities linked to later Parkinson’s diagnosis

Written by Sharon Salt, Senior Editor

According to a recent study from scientists at the University of California San Francisco Weill Institute for Neurosciences (CA, USA), older men who have a weak or irregular circadian rhythm may be more likely to develop Parkinson’s disease later in life. The results, which have been published in JAMA Neurology, indicated that reduced circadian rhythmicity was associated with an increased risk of incident Parkinson’s disease, suggesting that circadian abnormalities could represent an important prodromal feature for Parkinson’s. “Parkinson’s is a disease that probably takes decades to develop, and apart from changes in movement, earlier signs might be critical in understanding...
