Shaik Sameena*

ABSTRACT

Cerebrovascular attack is caused by either Ischemic or Hemorrhagic stroke. The major chief complaints in CVA patients includes Aphasia and Slurred speech which is caused due to formation of Infarcts or lesions in Frontal lobe, Parietal lobe, Temporal lobe. Type of Aphasia can be known by Assessment tools such as Multilingual Aphasia Examination, Boston Diagnostic Aphasia Examination. Site or Regions of Infracts can be known by MRI and CT scans. Infracts of Wernicke’s Aphasia are seen in Parietal and Temporal lobes due to inferior middle cerebral artery occlusion [MCA] most often that develops in older people. This review article has reviewed 49 patients with CVA and chief complaints of Aphasia are taken as subjects with age of 25-89, out of which 38 patients with Ischemia stroke developed Infracts under Group I. 11 patients with Hemorrhagic stroke of which 7 develop Intra cerebral Hemorrhage [ICH] under Group II and 4 develop Aneurysmal Subarachnoid hemorrhage [SAH] under Group III. The main causes of Wernicke’s Aphasia in older people caused by brain injury or lesions in posterior part of brain due Inferior MCA occlusion.
