Dexamethasone suppression test and primary obsessional compulsive disorder.

This report explores the role played by DSM-III Major Depression in the Nonsuppressor status of a sample of 29 subjects suffering from DSM-III Obsessive Compulsive Disorder (OCD). Five subjects were found to be Nonsuppressors. Further analysis showed that it is likely that Nonsuppressor status depended upon the concomitant presence of Major Depression rather than upon the OCD itself.
