Echothymia is stimulus-bound affective behavior, an echophenomenon in the domain of affect. Like echolalia and echopraxia, it is a concomitant of the environmental dependency associated with dysfunction of the frontal-striatal systems that mediate so-called frontal lobe functions. The authors introduce the definition and phenomenology of echothymia, overview its differential diagnosis and clinical significance, and suggest ways in which understanding echothymia may contribute to clinical management.
