Which option best describes the typical facial presentation in Parkinson disease?

• A. Expressive facial movements
• B. Masklike facial expression
• C. Drooping eyelids with ptosis
• D. Wide, animated facial gestures

Answer: (B)

In Parkinson disease the facial muscles move slowly and with limited range, leading to a reduced ability to convey emotion through the face. This phenomenon, called hypomimia or masked facies, gives the face a blank or expressionless look even when the person is speaking or reacting. So the description that fits best is a masklike facial expression. This contrasts with expressive or animated facial movements, which would imply more rapid or open facial activity. Ptosis can occur in some conditions, but it isn’t the defining facial feature of Parkinson’s, and wide, animated gestures aren’t characteristic of it.
