STROKE
Strokes can occur due to various factors, and they generally fall into two main categories: ischemic and hemorrhagic strokes.
1. Ischemic Stroke:
This is the most common type, caused by a blockage in a blood vessel supplying blood to the brain. Common causes include:
a: Atherosclerosis: Buildup of fatty deposits in the arteries.
b: Blood Clots: These can form in the heart or arteries and travel to the brain.
2. Hemorrhagic Stroke: This occurs when a blood vessel in the brain bursts, leading to bleeding. Causes include:
-High Blood Pressure: Chronic hypertension can weaken blood vessels.
- Aneurysms: Weak spots in blood vessel walls that can rupture.
- Arteriovenous Malformations (AVMs): Abnormal connections between arteries and veins.
Risk Factors:
- High blood pressure
- Diabetes
- High cholesterol
- Smoking
- Obesity
- Sedentary lifestyle
- Family history of stroke
