This review explores the possible correlation between psychological trauma and catatonia, with initial data suggesting a link between intense fear responses associated with trauma and PTSD and some forms of catatonic responses. Future studies may change our understanding of the etiology of a subtype of catatonia and point to potential targets for further research on the underlying biological mechanisms.
Although catatonia is related to several medical conditions, catatonia as a response to trauma and posttraumatic stress disorder (PTSD) is less clear. The aim of this review is to explore the small emerging body of preliminary evidence that suggests a possible correlation between psychological trauma and catatonia. Initial data suggests a correlation between episodes of intense fear associated with trauma and PTSD and some forms of catatonic responses. Although this relationship is still speculative to be causative, it can have important implications if confirmed. This is especially salient when it is examined alongside existing studies of the response to fear in animals and the phenomenon of tonic immobility, which bears a striking resemblance to catatonia in humans. If prospective studies further support the initial findings, it could change our conceptual understanding of the etiology of a subtype of catatonia substantially while pointing to likely targets of further research to understand the biological mechanisms that underlie the illness.
