Hypomimia

Definition
Hypomimia, a Medical sign, is a reduced degree of facial expression. It can be caused by motor impairment (for example, weakness or paralysis of the facial muscles), as in Parkinson's disease, or by other causes, like psychological or psychiatric factors (for example, if a patient actually doesn't feel emotions, and thus doesn't show any expression).
