Decreasing trend in incidence and mortality from stroke in Hisayama residents, Japan.

The incidence and mortality from stroke during the period 1961 to 1976, among 1,621 subjects aged 40 and over at entry, in Hisayama community, Kyushu Island, Japan, were analyzed. A major age-related decline in the incidence of cerebral infarction occurred in both sexes. The average annual incidence of cerebral infarction also fell continuously in both sexes throughout the whole observation period. The 5-year annual mortality rate from cerebral hemorrhage also showed a decrease in men, but fluctuated in women. The 5-year mortality from cerebral infarction slightly increased in both sexes.

Pathological studies on the intracerebral and retinal arteries in cerebrovascular and noncerebrovascular diseases.

Histological examinations of the intracerebral and retinal arteries were preformed in patients who had cerebrovascular disease and in those cases who did nott. Fibrinoid degeneration, fibrous nodule, and splitting, which are most frequently found in putamen, thalamus and pons, are thought to be the main changes in cerebral hemorrhage and infarction. Fibrous and fibro-hyalinoid thickenings of the retinal arteries were found mainly in the neighboring region of the optic disk, which reflects the changes of the intracerebral arteries. Hyalinoid thickening was found in the ora serrata, which does not reflect the changes of the intracerebral arteries. Our results suggest that patients with these retinal artery changes in the region near the optic disk if moderate to severe have an increased risk of having or incurring cerebral hemorrhage and infarction, but the arterial changes in the ora serrata do not always indicate risk of cerebral hemorrhage and infarction.
