Correct answer: C — Non-motor symptoms of Parkinson's disease

Non-motor symptoms (NMS) of PD include autonomic dysfunction (constipation, urinary symptoms, orthostatic hypotension, sialorrhoea), sleep disturbance, mood disorders, cognitive impairment, pain, and fatigue. They are often underrecognised but significantly impact quality of life and may dominate the clinical picture in advanced PD. NICE NG71 emphasises the importance of systematically assessing and treating non-motor symptoms. A: Motor complications are dyskinesia and fluctuations. C: Some may be drug-related but most are intrinsic to PD. D: These are core PD non-motor features. E: These occur in idiopathic PD, not exclusively Parkinson-plus.
