[Clinical and pathological study of cerebrovascular disease in the 60-101 age group].
The purpose of this study is to clarify the clinical and pathological characteristics of cerebrovascular disease in nonagenarians and centenarians. In all autopsied cases from 1981 to 1986 (60-101 years old, 138 men and 157 women), cerebrovascular disease was observed in 32 cases (90-101 years old, 8 men and 24 women) and 174 cases (60-89 years old, 95 men and 79 women) in our hospital. The incidence of cerebrovascular disease was 58.3%, 68.8%, 75.1% and 64%, pathologically, in their sixties (60's), seventies (70's), eighties (80's) and over nineties (90's) respectively. In those who had cerebrovascular disease, cerebral infarctions were found in 79.9% of the cases of the under-90 group and 81.2% of cases of the over-90 group. In both groups, infarction was mainly found in over 2 regions, in the putamen, caudate, thalamus and in the white matter and cortex of the frontal lobe. In the over-90 group, the medium-sized infarctions decreased and small-sized infarctions increased. Cerebral hemorrhages were found in 16.1% of cases in the under-90 group and 12.6% of cases in the over-90 group. In the over-90 group, large-sized hemorrhages were found in 75%, and the incidence of hemorrhages was 50%, 50% in the lentiform nucleus and the subcortex respectively. The frequency of mental symptoms, frontal signs and oral dyskinesia in the over-90 group was significantly higher than in the under-90 group. The onset of cerebrovascular attacks was unknown in 43.8% cases.(ABSTRACT TRUNCATED AT 250 WORDS)
