Abstract
Cerebral blood flow (CBF) was measured in 180 patients one to eight weeks after sustaining an acute episode of cerebrovascular ischaemia. The patients were divided into four groups in relation to their performance of daily activities at the time of CBF study: score 0 - full previous activities; 1 - slight; 2 - moderate; and 3 - severe disability. There was a statistically highly significant difference between the flow values of these groups. The patients were regrouped according to their rehabilitation status (score 0 to 3 as above, score 4 - dead) after a mean observation period of 34 months. The differences between flow values were even higher now, significant contingency coefficients being found between flow values and final social scores. When the patients were grouped according to changes in performance scores there again were statistically significant differences in flow values between the groups. The relationship between flow values and social re-integration after cerebrovascular ischaemia indicates the value of CBF measurements for prognosticating a patient's rehabilitation ability after stroke.
