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)
