Understanding Stroke: Early Signs, Causes, Prevention & Recovery
A stroke is a medical emergency that occurs when the blood supply to part of the brain is interrupted or reduced. According to the World Health Organization (WHO), stroke is the second leading cause of death globally, responsible for over 6 million deaths each year. It can strike without warning and leave a lasting impact on physical and cognitive abilities. This article explores everything you must know about stroke—including causes, early signs, prevention, and treatment—based on research, statistics, and expert insights.
🧠 What is a Stroke?
A stroke happens when blood flow to the brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Brain cells begin to die within minutes. There are three main types of stroke:
- Ischemic Stroke: Caused by a blockage in an artery supplying blood to the brain. It accounts for about 87% of all strokes.
- Hemorrhagic Stroke: Caused by bleeding in or around the brain due to a burst blood vessel.
- Transient Ischemic Attack (TIA): Also known as a mini-stroke, it results from a temporary clot and serves as a warning for a future full-blown stroke.
🚨 Early Warning Signs of Stroke (Use the FAST Method)
Recognizing the early signs of a stroke can save lives. Use the acronym FAST to detect warning symptoms:
- F - Face Drooping: One side of the face droops or feels numb.
- A - Arm Weakness: One arm becomes weak or numb.
- S - Speech Difficulty: Slurred or unclear speech.
- T - Time to Call Emergency: Call emergency services immediately if any of these signs appear.
Other symptoms include sudden dizziness, blurred vision, severe headache, and confusion.
📊 Stroke Risk Factors and Causes
- High blood pressure (leading cause)
- Diabetes and insulin resistance
- High cholesterol levels
- Obesity and physical inactivity
- Smoking and alcohol abuse
- Family history of stroke
According to a 2024 study published in The Lancet, lifestyle-related risk factors contribute to over 70% of strokes globally.

🩺 Diagnosis & Treatment Options
Diagnosis includes MRI, CT scan, and carotid ultrasound. Treatments depend on stroke type:
- Ischemic Stroke: Treated with clot-busting medications like tPA (Tissue Plasminogen Activator).
