Associations of epigenetic age acceleration with motor impairment: Evidence from the Parkinson's Progression Markers Initiative cohort.

Biological aging clocks linked to movement problems in Parkinson's disease may help predict who will decline faster and need closer monitoring.

This study from the PPMI cohort demonstrates that epigenetic age acceleration is associated with motor impairment in Parkinson's disease. The finding links biological aging clocks to PD progression, potentially useful for prognosis and stratification.
