Stroke Basics

A stroke occurs when an artery carrying blood to the brain gets clogged or bursts disrupting blood supply. The brain, deprived of oxygen, begins to die. The majority of strokes result from clogging of arteries; artery bursts account for less than 20% of strokes.

lead to memory loss. When the stroke damages the left part of the brain, the results are different. The victim’s
right body can be paralyzed. Also, the victim can suffer speech problems or memory loss.

Some of the common symptoms of stroke are: sudden numbness or weakness in the face, arm or leg, especially on one side of the body; sudden problems in speaking; sudden blurring of vision in one or both eyes; sudden trouble in walking, dizziness or loss of balance. Anyone who experiences these symptoms must immediately seek medical help.

The strokes are of two kinds. These are: ischemic strokes that result from the clogging of arteries and hemorrhagic
strokes that are caused by the bursting of arteries in the brain. The hemorrhagic stroke requires surgical intervention because the blood flows out of the ruptured artery and starts exercising pressure on the brain. The ischemic stroke is treated by removing or dissolving clots.
