_____________ is a nervous disorder characterized by involuntary tremors, diminished motor power and rigidity?
Correct answer: D. Parkinson's disease
- A. Epilepsy
- B. Meningitis
- C. Alzheimer's disease
- D. Parkinson's disease
Explanation
Parkinson's disease results mainly from degeneration of dopamine-producing neurons involved in motor control, causing resting tremors, rigidity and reduced movement. Epilepsy is the most likely alternative because it is also a nervous disorder, but it is characterized mainly by recurrent seizures rather than progressive motor rigidity.
