Question

Which of the following is a characteristic feature of Parkinson’s disease?

• A. Bradykinesia
• B. Chorea
• C. Myoclonus
• D. Dystonia

Hint:

Parkinson’s disease core triad: Tremor (resting), Rigidity, Bradykinesia.

Answer 1

The Correct Option is A

Bradykinesia (slowness of movement) is a hallmark symptom of Parkinson’s disease, along with resting tremor, rigidity, and postural instability. It results from degeneration of dopaminergic neurons in the substantia nigra, leading to basal ganglia dysfunction.
- Chorea: rapid, jerky movements (seen in Huntington’s disease)
- Myoclonus: sudden, brief muscle jerks
- Dystonia: sustained muscle contractions causing abnormal postures
