Correct answer: C — Regular structured exercise significantly improves motor function (gait speed, balance, UPDRS scores), non-motor symptoms (cognition, mood, sleep, fatigue), and may have neuroprotective effects — it is one of the most effective interventions in PD management
Exercise in PD has overwhelming evidence of benefit: (1) improves motor function (gait speed, balance, UPDRS scores), (2) reduces falls, (3) improves cognition (particularly executive function), (4) improves mood and reduces depression/anxiety, (5) improves sleep quality, (6) may slow disease progression (emerging neuroprotective evidence from animal models and human observational studies). NICE NG71 recommends exercise as a core part of PD management. Types: aerobic, resistance, balance, tai chi, boxing, dance, Nordic walking. A: Strong evidence of benefit. C: Exercise improves symptoms. D: All types are beneficial with appropriate supervision. E: Should start early.
