A 50-year-old patient showing, symptoms of tremor, loss of motor movement, and muscle rigidity, is diagnosed with the death of neurons in the midbrain that normally releases dopamine.
Correct answer: D. Parkinson's disease
- A. Epilepsy
- B. Graves' disease
- C. Alzheimer's disease
- D. Parkinson's disease
Explanation
Parkinson's disease is the correct answer because it is a neurodegenerative disorder characterized by symptoms such as tremor, muscle rigidity, and bradykinesia (slowness of movement). These symptoms are due to the loss of dopamine-producing neurons in the substantia nigra region of the midbrain. The other disorders listed do not primarily exhibit these symptoms:Epilepsy involves seizures and is not associated with the motor symptoms described.Graves' disease affects the thyroid and is unrelated to the neurological symptoms in the question.Alzheimer's disease affects cognitive function and memory rather than motor control.
