A 41-year-old Malaysian man is referred to the PMHNP following an incident at work. He says a coworker insulted him, and the next thing he knows the police were called. He does not remember attacking the coworker, but he was arrested for assault. Which culture-bound syndrome should the PMHNP include in the differential diagnosis?

Choice A reason: Ataque de nervios is a culture-bound syndrome observed in Latin American populations, characterized by episodes of crying, trembling, and aggression, usually in response to family stress, not common in Malaysian men. Choice B reason: Khayal is a Malaysian syndrome associated with anxiety, palpitations, and fear of death, but it does not involve violent outbursts with amnesia. Choice C reason: Possession syndrome involves a belief of being controlled by spirits, usually with stereotyped behaviors, but does not fit the sudden aggressive episode with amnesia described here. Choice D reason: This is correct. Amok is a culture-bound syndrome primarily described in Malaysia and other Southeast Asian countries, characterized by sudden outbursts of violent behavior, often in response to perceived insult, followed by amnesia of the event.
