A 39-year-old Cambodian man presents to the PMHNP for an evaluation following an event that he refers to as "Khayal." Which culture-bound syndrome should the PMHNP include in the differential diagnosis?

Choice A reason: Fright syndromes typically involve transient anxiety and sadness but do not include the physical manifestations associated with Khayal. Choice B reason: Weakness of the nervous system, such as neurasthenia, is associated with chronic fatigue and somatic complaints but does not reflect the acute episodic presentation of Khayal. Choice C reason: Khayal is a Cambodian culture-bound syndrome characterized by a wind attack or sudden anxiety episode with physical symptoms, including tinnitus, palpitations, and neck soreness. It resembles a panic attack culturally contextualized. Choice D reason: Excessive rumination or “thinking too much” is associated with some African or Caribbean syndromes but does not describe Khayal.
