A lack of facial expressions can occur in various conditions. Catatonia is a term that is used to describe a state of stupor or unresponsiveness in a person who is otherwise awake. Lack of facial expressions is one sign of catatonia, which can occur in association with a psychiatric disorder, like schizophrenia. Diseases that cause damage to the brain and its function can also lead to a lack of responsiveness, including a lack of facial expressions. Examples include brain trauma and encephalitis.
