Original abstract
The medical records and autopsy data of patients over the age of 70 years at death with a diagnosis of cortical artery infarction (CAI) in the Yokufukai Geriatric Hospital were reviewed. Among 690 autopsied cases from 1981 to 1988, there were 45 cases (21 men and 24 women) with CAI available for this study. Fourteen cases (31.1%) suffered CAI while hospitalized for another disorder. Their ages at death ranged from 70 to 102 years with a mean of 82.4 years. From the results of this neurological and psychological analysis, the residuals of senile stroke were classified into six subtypes: 1) cerebrovascular dementia, 2) cerebrovascular Parkinsonism, 3) pseudobulbar palsy, 4) chronic stage of aphasia, 5) slowly-progressive decreased motivation or spontaneity without dementia, 6) the so-called bedridden state (prolonged vegetative or apallic state). Sixty-nine percent had anamnetic hypertension before the stroke. The ages at which they became bedridden ranged from 69 to 102 years with a mean of 81.8 years. Within one year after becoming bedridden, 83.3% of all patients died. The bedridden state in the elderly with residual CAI indicated a poor prognosis within one year after stroke. Causes of death included brain death in 22.3% of all patients, pneumonia in 20.0%, and digestive bleeding in 8.9%.
