Can Trauma Condition Vulnerable Individuals to Develop Catatonic Symptoms?

Limited research has been done on the risk and predisposing factors of catatonic symptoms induced by traumatic events. There seem to be two types or constructs of conditioning that predispose an individual to catatonic symptoms in response to traumatic events: external conditioning and internal conditioning. Here, we review a study that found a significant correlation between the Bush–Francis Catatonia Scale and the Adverse Childhood Experience questionnaire; we also review studies of rats that were conditioned to expect an electric shock who developed catatonia-like immobility without the shock being applied. We also review the clinical case report of a previously traumatized individual.
