Certain cultural syndromes seem to increase the risk of panic attacks by generating catastrophic cognitions about symptoms of autonomic arousal. These schemas create a constant anxious scanning of the body, hence facilitating, maintaining, and producing panic. As a case in point, a Khmer fainting syndrome,'wind overload' (kyol goeu), results in dire expectations concerning the autonomic symptoms experienced upon standing, thus contributing to the high rate of orthostatically induced panic observed in this population.

This study surveys Khmer refugees attending two psychiatric clinics to determine both the prevalence of panic disorder as well as panic attack subtypes in those suffering panic disorder. A culturally valid adaptation of the SCID-panic module, the Cambodian Panic Disorder Survey (CPDS), was administered to 89 consecutive Cambodian refugees attending these psychiatric clinics. Utilizing culturally sensitive panic probes, the CPDS provides information regarding both the presence of panic disorder and panic-attack subtypes during the month prior to interview. Of 89 patients surveyed at two psychiatric clinics, 53 (60%) currently suffered panic disorder. Among the 53 patients suffering panic disorder, the most common panic attack subtypes during the previous month were the following: "sore neck" [51% of the 53 panic disorder patients (PDPs)], orthostatic dizziness (49% of PDPs), gastrointestinal distress (26% of PDPs), effort induced (21% of PDPs), olfactory induced (21% of PDPs), and "while-sitting dizziness" (16% of PDPs).

Kyol goeu (literally, 'wind overload') is an orthostatically triggered syncopal syndrome often found among Khmer refugees in the US. In the present study, 36 of 100 (36%) Khmer patients attending a psychiatric clinic were found to have suffered a kyol goeu episode in the past, whereas 60 of 100 (60%) patients had experienced a near-kyol goeu event in the last six months. Following a surveybased characterization of kyol goeu, as well as the presentation of case vignettes, the article discusses six mechanisms resulting in the high prevalence of the syndrome. The article concludes by comparing kyol goeu and ataque de nervios.

According to the Khmer conception, a person suffering 'weak heart' (khsaoy beh daung) has episodes of palpitations on slight provocation (e.g. triggered by orthostasis, anger, a noise, worry, an odor or exercise) and runs the risk of dying of heart arrest during these periods of palpitations; too, the sufferer typically has other symptoms attributed to the purported cardiac dysfunction: fatigue, shortness of breath, and orthostatic dizziness. Many Khmer refugees suffer this cultural syndrome, an anxious-dysphoria ontology, most probably of French colonial provenance. The syndrome demonstrates considerable overlap with those Western illness categories that feature panic attacks, in particular post-traumatic stress disorder (PTSD) and panic disorder. In a psychiatric clinic survey, 60 percent (60/100) of those assessed believed themselves to currently suffer 'weak heart'; 90 percent (54/60) of those considering themselves to suffer from 'weak heart' thought that palpitations (e.g., those resulting from a loud noise or orthostasis) might result in death. The article illustrates the profoundly culturally constructed nature of 'cardiac sensations,' located in a specific historical trajectory and episteme; too, the article suggests that trauma may result more in panic disorder than 'PTSD' when autonomic arousal symptoms (in the present case, palpitations) are considered potentially life-threatening.
