title: Cranial computed tomography of elderly patients: an evaluation of its use in acute neurological presentations.
abstract: We assessed the use of cranial computed tomography (CT) in elderly patients with acute neurological deficit and its influence on patient management. Clinical notes from 100 consecutive CT referrals from geriatric admissions presenting with acute neurological deficit were reviewed and categorized according to clinical presentation. CT results and subsequent therapy were recorded. Twenty of the patients had treatable lesions (in 6 out of 14 patients with signs atypical of stroke and 7 out of 19 patients with acute confusion). These two groups contained 68% of all treatable lesions found. Forty-four scans yielded no new diagnostic information; these included all scans for transient ischaemic attacks and for progression of stroke. The remaining scans yielded information regarding pathology but did not alter patient management. CT is a valuable first-line investigation in elderly patients presenting with signs atypical of stroke and unexplained confusion but may be less useful in patients with other presentations.
