The following are the most common forms of cerebrovascular disease:
Cerebrovascular disease occurs when there is restrictions in blood flow due to vessel narrowing, clot formation, blockage or blood vessel rupture. Lack of sufficient blood flow affect brain tissue and may cause a stroke.
The symptoms of cerebrovascular disease depend on the location of the hemorrhage, thrombus or embolus and the extent of cerebral tissue affected. General symptoms of a hemorrhagic or ischemic event include motor dysfunction, such as paralysis of one side (hemiplegia) and weakness on one side of the body (hemiparesis). Early in a cerebrovascular attack (CVA), you may experience weakness (flaccid paralysis) followed by increased muscle tone and spasticity; you could also lose your gag reflex or ability to cough. You could also lose half of your visual field (homonymous hemianopia) and the ability to recognize an object (agnosia).
Other symptoms of a cerebrovascular attack may include:
Communication deficits may occur such as:
Your physician will look for specific neurological, motor and sensory deficits that include changes in vision or visual fields, abnormal reflexes, abnormal eye movements, muscle weakness, decreased sensation and other changes. Other tests can include:
Blood platelet inhibitors including aspirin, dipyridamole, ticlopidine, and clopidogrel are effective in reducing the risk of stroke. Cholesterol-lowering medications called statins are usually given to reduce the risk of ischemic stroke.
A stroke is a medical emergency and should be evaluated immediately when symptoms occur by calling 911.
