Abstract
Dissociative convulsions or pseudoseizures are a difficult to treat common psychiatric condition. In a subset of these patients, the chief complaint is clenching of teeth with apparent nonresponsiveness alone. Neither drugs nor psychotherapeutic interventions have been found to be of much help in its management. Report of two such subsets of cases is presented, in which patients with dissociative convulsions showed sudden, dramatic, and sustained good response to the addition of a muscle relaxant eperisone.
