Please explain CVA
CVA stands for cerebrovascular accident. A CVA is commonly called a stroke. There are basically two types of CVA's, hemorrhagic and ischemic.
A hemorrhagic stroke is when a blood vessel somewhere in the brain ruptures and you have bleeding into the brain tissue. Any blood vessel can rupture but most commonly it is an artery. This rapid loss of blood from the vascular space can cause neurologic symptoms such as headache, blurred vision, hemiplegia or paraplegia. This event is a true emergency.
An ischemic stroke is when a blood vessel in he brain is partly occluded resulting in decreased blood flow to the distal areas past the ischemic foci. Symptoms are similar to a hemorrhagic stroke but usually not as severe.
CVA is Cerebro-Vascular Accident which is a medical emergency, and may result in permanent damages and other complications, even death. Commonly called a 'Stroke', CVA is caused by disturbance in the supply of blood in the brain due to a blocked or a burst vessel. The affected part of the brain is unable to function, leading to symptoms like inability to move one or more limbs, inability to understand and formulate speech, loss of vision in one side of the visual field, head-ache and many more.
Advanced age, diabetes, high cholesterol, tension & stress, smoking are some of the major factors behind CVA. Strokes are basically of two types--Ischemic and Hemorrhagic. The first type refers to sudden decrease in blood-supply because of thrombosis or embolism. The second type refers to sudden rupture in a vessel and hemorrhage either inside or outside the brain.
