Stroke

**Stroke**

A stroke occurs when blood flow to a part of the brain is interrupted, depriving it of oxygen and nutrients. This can cause permanent damage to the brain tissue and lead to a range of disabilities, including paralysis, speech problems, cognitive impairment, and vision problems.

**Types of Strokes:**

* **Ischemic stroke:** Caused by a blockage in an artery leading to the brain, most often by a blood clot.
* **Hemorrhagic stroke:** Caused by a rupture in an artery or vein in the brain, leading to bleeding.

* Sickle cell disease

**Symptoms:**

* Sudden numbness or weakness on one side of the body
