The CT and median somatosensory and brainstem auditory evoked potentials (SEP and BAEP) were studied in 80 patients with spontaneous putaminal hemorrhage for their values in the early prediction of functional outcome. The CT scan was performed within 2 days and EPs within a week after the onset of symptoms. The activities of daily living was assessed at 6 months. Patients with good functional recovery had the following findings: 1) the hemorrhage had not involved the thalamus or the posterior limb of the internal capsule; 2) the SEPs were normal or had prolonged central conduction time; and 3) the BAEP was normal. When the cortical SEPs were absent, the majority of patients were moderately or severely disabled. Attenuation or absence of BAEP wave V always forecast a grave prognosis. It is concluded that the combined use of CT, SEP and BAEP is an objective and reliable method for the early prediction of functional outcome in patients with putantinal hemorrhage.
