Which of the following is a hereditary disease of the cerebral cortex?

Answer options

• A. Huntington chorea.
• B. Lou Gehrig disease.
• C. Bell’s palsy.
• D. Guillain-Barre syndrome.

Correct answer: C

Explanation

The correct answer is C, Bell’s palsy, which is characterized by sudden, temporary weakness in the muscles on one side of the face and can have hereditary factors. A is Huntington chorea, which is a genetic disorder but affects the basal ganglia rather than the cerebral cortex. B, Lou Gehrig disease, is a neurodegenerative condition, and D, Guillain-Barre syndrome, is an autoimmune disorder, neither of which are classified as hereditary diseases of the cerebral cortex.
