A patient with Parkinson's disease shows several characteristic facial features.


Facial features of a patient with Parkinson's disease:

(1) hypokinesia or akinesia of facial muscles, resulting in an absence of facial expression ("mask-like")

(2) blank stare with unblinking eyes, often seeming to be peering upward

(3) forward flexion of the head and trunk

(4) preserved eye movements

(5) tremor in the head and/or jaw

(6) a soft, monotonous voice with loss of modulation

(7) variable drooling (sialorrhea, due to decreased swallowing of saliva)
