Which finding is most characteristic of Bell's Palsy?

• A. One-sided facial droop
• B. Bilateral facial droop
• C. Slurred speech
• D. Headache with neck stiffness

Answer: (A)

Bell's palsy is an acute dysfunction of the facial nerve (CN VII) that causes weakness of the muscles on one side of the face. The finding most characteristic is a one-sided facial droop, often with inability to close the eye or smile on that side. This focal facial weakness helps distinguish it from conditions that affect other parts of the body or cause different symptoms. A bilateral droop would suggest a more diffuse process, slurred speech points to a central problem such as a stroke or intoxication, and headache with neck stiffness suggests meningitis or another CNS issue rather than isolated facial nerve palsy.
