Physical disorder among day hospital patients.

During a six-month period, physical disorder was found among 50 per cent of the 133 patients at a day hospital. Few of these cases (5) had organic brain syndromes. Among the remainder (62) physical disorder was not associated with sex, formal psychiatric diagnosis or time of referral to the hospital; of those 33 patients with a neurological disorder, one-third had previously been diagnosed to be hysterical. For this 'hysterical' group, however, associations with folate deficiency, organic brain disease, and depression were noted. The need is demonstrated for routine investigations among day hospital patients with particular attention for those with atypical features.
