Long-Term Physical Activity Associated With Slower Progression of Parkinson's Symptoms

Parkinson's disease is a progressive neurological disorder that affects movement and can also affect memory, thinking, sleep and mood. Exercise is often recommended as part of supportive care because it can help maintain mobility, strength, balance and general physical health. The reported seven-year study compared activity levels with changes in cognitive tests and measures of Parkinson's symptoms. People in the most active group showed much smaller average declines in thinking and memory scores, while movement symptoms worsened more slowly than in the least active group. These results suggest that maintaining activity over time may be beneficial for people living with Parkinson's disease. However, the study is observational: it cannot prove that exercise alone caused the differences. People with milder symptoms may be more able to remain active, and other health or lifestyle factors could influence the results. Exercise should be adapted to each person's mobility, balance, cardiovascular health and risk of falling. Physiotherapists can help develop safe programmes that may include walking, strength exercises, balance training or other activities suited to the individual. The findings support physical activity as a potential part of comprehensive Parkinson's care, not as a cure or replacement for prescribed treatment.
