Pen-y-fai Hospital, Bridgend.
The performance of the dexamethasone suppression test was assessed in 90
consecutive admissions with a diagnosis of depression, categorised
according to two classification systems (DSM-III and ICD-9). Non-
suppression was found in most of the diagnostic categories, but there was a
highly significant association with the DSM-III classification 'major
depressive episode with melancholia' (52%) in comparison with the ICD group
'manic-depressive illness-depressed' (29%).
