title: Involuntary emotional expression disorder: definition, diagnosis, and measurement scales.
abstract: Involuntary emotional expression disorder (IEED) is a syndrome in which emotional or affective motor control becomes dysregulated as a result of brain damage from neurological disease or as a result of brain injury. A debilitating disorder with persistent symptoms, IEED has a significant impact upon the lives of patients and caregivers, but is often overlooked or misdiagnosed. IEED is a clinically well-defined disorder, and specific criteria may be used when making a diagnosis. It must be distinguished from depression or other psychological and neurological conditions. Several assessment scales have been validated for use in IEED, in order to evaluate the baseline severity and to track the course of the disorder and response to treatment.
