Stroke: A Comprehensive Overview
Table of Contents
Stroke is a major cause of death and disability worldwide. Understanding its causes, symptoms, and treatments can be lifesaving. This article provides a comprehensive overview of stroke for the general public.
What is a Stroke?
A stroke occurs when blood flow to a part of the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die.
Strokes can be categorized based on their cause: ischemic and hemorrhagic.
- Ischemic stroke: Occurs when a blood vessel supplying blood to the brain is obstructed, often by a blood clot.
- Hemorrhagic stroke: Occurs when a blood vessel in the brain ruptures or leaks blood.
Stroke symptoms vary depending on the affected region of the brain, but they usually begin suddenly. Common symptoms include:
- Difficulty speaking or understanding speech
- Paralysis or numbness of the face, arm, or leg
- Blurred or blackened vision in one or both eyes
- Dizziness or loss of balance
If someone shows symptoms of a stroke, it's crucial to seek medical attention immediately. Doctors may use several tests to diagnose stroke:
- Physical examination: Checking for high blood pressure and using a stethoscope to listen to the heart.
- Blood tests: To check sugar levels and other vital metrics.
- CT or MRI scans: To view an image of the brain.
Stroke treatment depends on its type:
- For ischemic strokes: Doctors often use clot-dissolving drugs. Another option is a procedure where doctors remove the clot with a device.
- For hemorrhagic strokes: Treatment focuses on controlling the bleeding and reducing pressure in the brain.
Rehabilitation is vital after a stroke, helping patients relearn skills lost due to damage to their brain.
