Strokes are commonly caused by some blockage that occurs within the arteries. Such blocks impair the function of arteries which is to carry blood to the brain.
This causes severe damage to certain parts of the brain and the body loses control of those activities which are controlled by that particular part of the brain. The affected person finds it difficult to speak or lose control over the movement of his arm or leg. The damage thus caused to the brain can be either partial or complete.
However, if immediate treatment is provided, there is minimal chance of damage as blood can be artificially provided to the brain.
