Among the neurologic diseases,C.V.A(Cerebro Vascular Accident) is

   the  most  prevalent  cause of fatality, that makes also a great number of

   patients disable to do their daily activities.So we can reduce the mortality

   rate by knowing the risk factors.In this study we tried to find frequency rate

   of Ischemic C.V.A and its risk factors.

         In this study  we used  386 patients folders, the diagnosis was generally

   based on clinical  symptoms  and  CT- scans in 1994-1995. The  studied risk

   factors  were: blood pressure,diabet , age , sex ,  hyperlipidemia, smoking

   and heart diseases.

         Analysis of the data showed that the most prevalent kind of C.V.A was

   Ischemic and the greatest risk factor was blood pressure.

         As the known risk factors of Ischemic  C.V.A  are  the  same  kind  that

   can be investigated and  treated  simply, so it is probable that we will be

   able to avoid  occuring it, by controlling these factors.
