Studies of psychiatric out-patients from India have found that diagnosis of some of the subcategories of the dissociative and conversion disorders of the ICD and DSM classificatory systems are rarely made in this setting. Moreover, it was found that a significant percentage of patients seen in psychiatric practice may not fit into the defined subcategories of dissociative (conversion) disorders of these systems of classification. We studied the prevalence of various ICD-10 and DSM-IV categories of dissociative (conversion) disorders and our own proposed category of 'brief dissociative stupor' (BDS), among all the in-patients of a psychiatric unit in a general teaching hospital, over a 2-year period. There were 18 patients who fulfilled our criteria for BDS and 18 patients in the second group which included all of the remaining subjects with a diagnosis of any other subcategory of dissociative disorder according to ICD-10. Our analysis revealed that there were no patients with a diagnosis of dissociative amnesia, fugue, stupor, trance and possession disorders or identity disorders. There were significantly more female patients in the BDS group, and they also had significantly more comorbid Axis-I diagnoses and panic attacks. Since 50% of our patients fulfilled the criteria for BDS, there is clearly a need for further studies to establish the prevalence of this subcategory in patients from other centres. The classification of these patients with this phenomenology is problematic. Inclusion of a subcategory of dissociative non-epileptic seizures, instead of dissociative convulsions, should improve the classification of dissociative (conversion) disorders.
