Definition
A decrease in facial animation that may be seen in Parkinson’s disease or with parkinsonism. It is felt to be a manifestation of bradykinesia in the face.
Current Knowledge
Facial movements are present, but a decrease in their frequency and amplitude gives the appearance of the patient wearing a mask. Patients may appear to family members as serious or depressed. Patients with masked facies may complain of dry eyes due to decreased eye blinking and of drooling from an associated decrease in the frequency of swallowing.
