LEFT HEMISPHERE CVA Right sided weakness/hemiplegia Aphasia Slow performance Visual field deficits RIGHT HEMISPHERE Left sided weakness/hemiplegia Spatial-perceptual deficits o Increased vulnerability to accidents Tends to minimize problems Short attention span Impaired judgement Impaired time concept TYPES OF CVAs Occlusion of an artery by an atheroma o Atheroma = fatty deposits and scarring that leads to tissue breakdown of the artery walls o Often develop in large arteries o Can trigger the formation of thrombosis ( THROMBUS )(blood clot) o Onset is gradual o May be preceded by transient ischemic attacks (TIAs) Sudden obstruction caused by an embolus ( EMBOLUS ) o Lodging in a cerebral artery o Localized unless multiple emboli are present Intracerebral hemorrhage ( HEMORRHAGE ) o Caused by rupture of a cerebral artery in patient with severe hypertension Effects are evident in both hemispheres. Complicated by secondary effects of bleeding Types of CVAs

Signs and symptoms o Loss of visual field or visual disturbances o Headache and photophobia o Intermittent periods of dysfunction o Nuchal rigidity caused by meningeal irritation o Vomiting, seizures, loss of consciousness in case of massive rupture; rapidly followed by death o Treatment Surgical treatment before rupture Antihypertensive drugs
