Stroke (Cerebrovascular Accident - CVA)
What is a Stroke?
A stroke, medically known as a Cerebrovascular Accident (CVA), occurs when the blood supply to a part of the brain is interrupted or reduced, preventing brain tissue from receiving oxygen and nutrients. Brain cells begin to die within minutes, making stroke a medical emergency that requires immediate treatment.
Types of Stroke
1. Ischemic Stroke
The most common type of stroke.
Occurs when a blood vessel supplying the brain becomes blocked by a clot.
2. Hemorrhagic Stroke
Occurs when a blood vessel in the brain ruptures and causes bleeding.
3. Transient Ischemic Attack (TIA)
Often called a "mini-stroke."
Causes temporary symptoms and serves as a warning sign for a future stroke.
Causes of Stroke
- High blood pressure (Hypertension)
- Diabetes
- High cholesterol
- Heart diseases
- Smoking
- Obesity
- Excessive alcohol consumption
- Physical inactivity

For Hemorrhagic Stroke:
Medications to control bleeding
Surgery if necessary
