3. Degeneration of nerves in the brain leading to tremors, shuffling gait, and muscle (mask-like facial expression); dopamine is deficient in the = c) brain

4. Deterioration of mental capacity (dementia) beginning in middle age; cerebral cortex atrophy, microscopic = d) neurofibrillary tangles

5. Unilateral facial = e) paralysis.

Explanation:

1. Epilepsy: Epilepsy is a disease that is characterized by sudden, transient disturbances of brain function which includes seizures. Epilepsy could be caused by genetic reasons or a damage or injury to the brain. The condition of epilepsy can not be cured but it can be effectively managed.
