Stroke
A stroke happens when blood stops flowing to any part of your brain, damaging brain cells. The effects of a stroke will depend on the part of the brain that was damaged, and the amount of damage done. [1] Strokes can happen at any point of your life, from infancy to adulthood. [2]

Symptoms of a Stroke

Other signs of a stroke include a sudden numbness or weakness of the face, arm, or leg, especially on one side; sudden confusion, trouble speaking or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, loss of balance or coordination; and sudden severe headache with no known cause. [5]
Stroke Treatment
The type of treatment depends on the type of stroke.
For an ischemic stroke, the treatment involves breaking down or removing the clot in the blood vessel. [6] For a hemorrhagic stroke, the treatment is to stop the bleeding. Depending on how much bleeding there is, the doctor may use a small tube called a catheter in your artery to put something, such as a coil, to prevent the blood vessel from rupturing further. Sometimes, surgery is required.6
