The diagnosis of intracerebral hemorrhage (ICH) has become precise with the advent of computerized tomography (CT). Little, however, is known concerning the long-term prognosis. Seventy consecutive patients with primary intracerebral hemorrhage (all known etiologies except hypertension excluded) proven by CT scan were studied. Follow up, averaging 2 1/2 years, was successful in all cases. The status of alertness, EKG, and clinical impression on admission were significant prognostic factors. As expected, mortality increased with size of the hematoma and ventricular rupture. Acute in hospital mortality was 40%. Another 17% died during the long-term follow up, but none of them from cerebrovascular disease. Ninety-two percent of the survivors were ambulatory at follow up. Hypertensive intracerebral hemorrhages, unlike aneurysms, rarely, if ever, rebleed. Patients are not likely to have a second bleed in another location. Hypertensive intracerebral hemorrhage is more common in blacks, especially young adult males with severe hypertension, but overall mortality is lower than thought prior to the CT scan. Most survivors can achieve independence and deserve aggression rehabilitation efforts.
