a. huntingtons disease
b. tay - sachs disease
c. meningitis
d. cerebral aneurysm

Explanation:

Huntington's disease is a genetic disorder that causes the progressive breakdown (degeneration) of nerve cells in the brain. It has a broad impact on a person's functional abilities and usually results in movement, thinking (cognitive) and psychiatric disorders. Tay - Sachs disease mainly affects the nervous system, especially in infants with symptoms like loss of motor skills etc., but the description in the question is more in line with Huntington's. Meningitis is an inflammation of the meninges (membranes covering the brain and spinal cord) usually due to infection. A cerebral aneurysm is a bulge in a blood vessel in the brain, which is different from the described cell - degeneration - related symptoms.

Answer:

A. Huntington's disease
