Formarly patients of stroke received treatments at their home, because it is generally said that those people who had a stroke had to take absolute rest. But recently these patients have come to have the need of medical cares for respiratory distress and the surgical treatment for the stroke has been surprisingly improved, so the number of stroke patients who are sent to the hospital is gradually increasing.
According to our investigation the number of inpatients of stroke has increased 0.8%to 2.2%these ten years and the ratio of cerebral hemorrhage and cerebral ischemic disease among them has become less. In 1969 the ratio of these patients is 32:18 and in 1979, 34:94.
Until the introduction of the computerized tomography (CT), stroke has been diagnosed by clinical symptoms, signs and several diagnostic procedures, for example, carotid angiography and brain scintigraphy. Utilizing CT, the most accurate anatomical localization and definition of the pathological sequelae to occlusive or hemorrhagic disorder are obtained. Among our recent 100 cases who have been diagnosed as cerebral infarction and examined with CT, 64 have been decided in less than 4 weeks after the disease was taken. Lately the infarct cases have been subdivided into two groups; the first consisted of those which were examined in less than 7 days after the disease was taken, the second, the infarct dated back 8 to 28 days before the examination.
