The content analysis of the selected articles was made using a script based on the proposed review of culture bound syndromes by Guarnaccia and Rogler (16): a) description of the characteristics of culture bound syndromes based on ethnographic and epidemiological data; b) socio-demographic characterization of those affected by culture bound syndromes; c) identification of comorbidities among individuals affected by culture bound syndromes and other psychiatric disorders.
This can be connected to the concept of PTSD itself-which could be still flawed or incomplete, or because the pattern of symptoms/behaviors triggered by stress are culturally mediated and PTSD was not originally described in cultures linked to the culture bound syndromes Susto, Nervios and Ataques de Nervios.
This review of epidemiological studies of low and medium income countries showed that low education, hunger, housing and financial problems, and socioeconomic status were related to higher rates of common mental diseases, defined as depression, anxiety and somatoform disorders, whose symptoms overlap with those presented by the culture bound syndromes Susto, Nervios and Ataques de Nervios.
Data on a North American sample of Hispanics indicate that those with higher levels of acculturation showed a higher prevalence of Ataques de Nervios episodes (44), which might indicate the influence of acculturation on culture bound syndromes. There is also no uniformity in the excluded articles about level of acculturation.
More studies are needed about psychiatric conditions related to stress, such as PTSD, and the culture bound syndromes Nervios, Susto and Ataques de Nervios, as well as studies about these syndromes in other LAC.
