Amok syndrome is an aggressive dissociative behavioral pattern derived from Malaysia that led to the English phrase, running amok. The word derives from the Malay word amuk, traditionally meaning "an episode of sudden mass assault against people or objects, usually by a single individual, following a period of brooding, which has traditionally been regarded as occurring especially in Malaysian culture but is now increasingly viewed as psychopathological behavior". The syndrome of "Amok" is found in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV TR). In the DSM-V, Amok syndrome is no longer considered a culture-bound syndrome, since the category of culture-bound syndrome has been removed.
