Stroke is a sudden loss of brain function caused by a disruption of the blood supply to the brain.
This can happen when a blood clot blocks an artery in the brain or when an artery in the brain ruptures.
There are two main types of stroke:
⦁ Ischemic stroke. ⦁ Hemorrhagic stroke. |
Ischemic stroke: is caused by a blood clot that blocks an artery in the brain. This is the most common type of stroke, accounting for about 87% of all strokes.
This can happen due to a number of factors, including high blood pressure, smoking, diabetes, and heart disease.
Hemorrhagic stroke: is caused by a blood vessel in the brain that ruptures and bleeds into the brain tissue. This is the less common type of stroke, accounting for about 13% of all strokes.
This can happen due to high blood pressure, aneurysms, and head injuries.

⦁ Weakness or paralysis on one side of the body. ⦁ Difficulty speaking or understanding speech. ⦁ Vision problems. ⦁ Problems with thinking or memory. |
