High-Intensity Exercise Can Reverse Neurodegeneration in Parkinson’s Disease

A new study suggests that high-intensity exercise may not only slow down but also potentially reverse neurodegeneration in Parkinson’s disease by preserving and enhancing dopamine-producing neurons. This finding is significant as it demonstrates, for the first time via brain imaging, that intense exercise can positively alter the brain's biology in Parkinson’s patients.

The study involved 10 patients and showed that after six months of high-intensity aerobic exercise, their dopamine signals and neuron health improved, indicating a protective and possibly restorative effect on the brain. Aerobic means “with oxygen.” When you participate in a continuous activity that increases your heart rate, your cells use oxygen to produce energy. Examples of aerobic exercise include walking, jogging, using cardio equipment, and swimming.
