[Epidemiologic aspects of cerebrovascular accidents in Tunisia].

We report the results of 3 epidemiological studies of stroke in Tunisia. In Tunis urban population, the crude annual incidence rate of stroke has been estimated at 0.54/1,000 and the prevalence rate at 6 to 14/1,000. The incidence rate adjusted to population at risk (greater than or equal to 45 years old), is around 1.92/1,000. A door-to-door survey conducted in Kelibia, according to a WHO protocol, showed a prevalence rate of 7.2/1,000 when adjusted to population at risk. CT diagnosed infarction and haemorrhage and excluded non-stroke cases (10 p. 100). Cerebral haemorrhage was more frequent than in other published studies (28 p. 100).
