Regular aerobic exercise has been shown to strengthen brain networks between spared regions, improve grey-matter volume, and enhance movement control in individuals with Parkinson's disease. The study published in Annals of Neurology suggests that exercise can stimulate compensatory capacity in the brain, leading to reduced symptoms.

Researchers found that the direct and indirect pathways in the basal ganglia play a crucial role in controlling actions, with the direct pathway sustaining action and the indirect pathway allowing switching between actions. This new model could have therapeutic implications for treating diseases like OCD and ADHD.
