Causes of stroke Oh No!  Strokes are caused by four things.

 When blood vessels are claughted with plaque blood cannot flow to the brain, causing less oxygen and blood to the brain, the pain causes of artery blockages are
 * 1. Blockage of artery**
 * The arteries in the brain become narrow
 * The brain arteries harden
 * Blood claughts from the heard can travel to the brain causing a stroke
 * high blood pressure (hypertension),
 * high cholesterol,
 * diabetes, and
 * smoking.


 * 2. Rupture of an artery (hemorrhage)**

When blood vessels in the brain start to bleed usually caused by high blood pressure


 * 3. Embolic stroke**

Embolic stroke is when there's is a clot in another part of the body breaks off and travels to the brain, clotting the brain causing a stroke. Usually these clots are in big arteries and harmless, but they travel to the brain and cloting the small arteries in the brain.


 * 4.** **Cerebral hemorrhage**

Celebral hemorrhage is when there is bleeding on the brain vessels causing blood and oxygen to only get to some parts of the brain. The brain could also become swelled because of the bleeding giving more stress on the brain, the brain will push towards the skull causing further brain issues


 * 5.** **Subarachnoid hemorrhage**

Subarachnoid hemorrhage is when blood accumulates in the space beneath the membrane that lines the brain. The blood originates from an abnormal blood vessel and start to leak blood. This will causes sudden headaches and severe brain damage if not treated quickly
