Which symptom is not typical of Parkinson’s disease?

• A. Unsteady gait
• B. Bradykinesia
• C. Expressive aphasia
• D. Muscle rigidity

Answer: (C)

Parkinson's disease centers on motor features arising from loss of dopamine in the nigrostriatal pathway. Typical signs include bradykinesia (slowness of movement), muscle rigidity, and gait or postural disturbances such as an unsteady gait. Expressive aphasia—difficulty producing language—is not a motor symptom of PD; it stems from damage to language areas in the cerebral cortex and is more often associated with stroke or other cortical lesions. So, while the motor signs listed fit the Parkinsonian pattern, expressive aphasia does not, making it not typical for Parkinson's disease.
