Association between Serum GGT and Acute stroke
Among all the neurologic diseases of adult life, stroke ranks first in frequency and importance. The common mode of expression of stro ke is a relatively sudden occur rence of a focal neurologic def icit. Strokes are broadly cate gorized as ischemic or hemorrhagic. Ischemic stroke is due to occlusion of a cerebral blood vessel and causes cerebral infarction . Ischemic strokes are classified by the underlying cause of the vascular occlusion. One of three main processes is usually operative: (1) atherosclerosis with superimposed thrombosis affecting large cerebral or extra cerebral blood vessels, (2) cerebral embolism, and (3) Occlusion of small cerebral vessels within the parenchyma of the brain. There are many other pathologic processes that lead to ischemic brain damage, not all associated with occlusion of cerebral vessels, including arterial dissection, infla mmatory condi tions such as vasculitis, thrombosis of cerebral veins and dural sinuses, in...
