Disrupted circadian rhythms linked to later Parkinson’s diagnoses

This shows a brainCircadian rhythm disruptions in older men have been linked to an increased risk of developing Parkinson’s disease. The findings suggest circadian disruptions may reflect the neurodegenerative processes already affecting the brain’s internal clock prior to the diagnosis of Parkinson’s. Circadian disruptions, researchers say, could be considered an early warning sign of Parkinson’s.
