Answer: (d) Parkinson’s disease

Parkinson’s disease is a progressive disorder of the nervous system caused by degeneration of the dopamine-producing neurons (of the substantia nigra of the midbrain). Shortage of dopamine leads to tremors, muscular rigidity, slowness of movement and loss of balance. Alzheimer’s disease involves loss of memory; Addison’s disease (adrenal cortex) and Graves’ disease (thyroid) are endocrine disorders.
