[Appointment of correlation between stroke and serum level of homocysteine, folic acid and vitamin B[12]]

ABSTRACT

Background: a stroke, or cerebrovascular accident [CVA], occurs when blood supply to part of the brain is disrupted, causing brain cells to die. Often by a blood clot or a fatty deposit due to atherosclerosis. CVA is third cause of death in the world and the most common causes of neurologic dysfunctions. There are different risk factors associated with CVA including systolic or diastolic hypertension, hyperlipidemia, smoking, alcohol abuse. Moderately increased concentration of homocysteine without homocystuinoria associated with increase of atherosclerosis, CVA and over ally mortality. The most common form of hyperhomocysteinemia is genetic. Increased serum level of homocysteine may reflect deficiency of folate, vitB6 and vitB[12]
