A landmark seven-year study published October 7, 2026, in Neurology — the official medical journal of the American Academy of Neurology — has found that physical activity offers two powerful, simultaneous benefits for people living with Parkinson’s disease: slowing the decline of both movement abilities and cognitive function.
The study, led by Dr. Dong-Woo Ryu, MD, PhD, of the University of Cincinnati in Ohio, followed 294 adults with mild to moderate Parkinson’s disease, with an average age of 66. Participants tracked their weekly physical activity — from brisk walking and swimming to vigorous activities like jogging and cycling. The results were striking: those who exercised more than eight hours per week showed almost no average cognitive decline over the study period.
“Parkinson’s disease is a brain disorder that causes movement and cognitive problems that gradually worsen, leading to disability and a loss of independence,” said Dr. Ryu. “Our study found physical activity may have dual benefits, with associations with slower declines in movement and cognition.” Researchers note the study identified a strong connection but does not yet prove that exercise directly causes slower disease progression — further clinical trials are needed. Still, the findings offer compelling, practical hope for millions living with Parkinson’s worldwide, reinforcing the role of everyday movement as a cornerstone of disease management and healthy aging.
