_____________ 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.
