Options:
Answer:
Solution:
Parkinson's disease is a progressive nervous system disorder that affects movement. It is caused by the degeneration of dopamine-producing neurons in the substantia nigra of the brain.
Typical symptoms of Parkinson's disease include:
1. Tremors (involuntary shaking, often starting in the hands or fingers).
2. Muscle stiffness or rigidity.
3. Bradykinesia (slowness of movement).
4. Postural instability leading to difficulty in walking and impaired balance.
Voluntary jerky movements are not a symptom of Parkinson's disease. The movements in Parkinson's are typically slow and rigid, while any jerky movements (like tremors or dyskinesia) are involuntary.
Answer: Voluntary jerky movements
