Abstract
Psychogeriatric patients have a number of associated neurological conditions, many of them not apparent clinically. This survey looks at the usefulness of cranial CT scan to identify them and its clinical implications. 64 out of 398 (16%) referrals from the Department of Psychiatry for cranial CT scanning over a 20-month period belonged to patients aged 60 years and above. Over 12 per cent of all new registrations belonging to this age group during the period were advised CT scanning. The commonest indication was suspected organic etiology of the clinical presentation. 1/3 of the entire sample of patients showed a significant finding on the scan in the form of infarcts, subdural haematoma or space-occupying lesion. Nearly 27 per cent of the patients with functional psychiatric illnesses had a significant finding on the scan. In 31 per cent of patients the scan influenced the management. Hypertension and diabetes mellitus did not increase the probability of abnormal CT scan.
