Stroke: Every Bangladeshi Should Know These Warning Signs — Your 4.5 Hour Window
Stroke is Bangladesh's second leading cause of death. Recognizing symptoms in the first few hours can mean the difference between recovery and disability.
A stroke happens when blood supply to part of your brain is suddenly cut off. Brain cells start dying within minutes. In Bangladesh, stroke kills more people than any disease except heart disease — and many survivors are left permanently disabled.
The tragedy? Most stroke deaths and disabilities in Bangladesh are preventable, either through risk factor control or by getting treatment within the critical 4.5-hour window.
Remember FAST
This is the most important acronym you'll ever learn:
F — Face: Ask the person to smile. Does one side of the face droop?
A — Arms: Ask them to raise both arms. Does one arm drift downward?
S — Speech: Ask them to repeat a simple phrase. Is their speech slurred or strange?
T — Time: If you observe ANY of these signs, call for help IMMEDIATELY.
The 4.5-Hour Window
There is a clot-busting drug (tPA) that can reverse stroke damage if given within 4.5 hours of symptom onset. After that window closes, the treatment becomes less effective. Many hospitals in Dhaka and Chittagong can now administer this — but only if you arrive in time.
Do NOT wait to see if symptoms improve on their own. Do NOT try home remedies. Do NOT drive slowly in case they 'feel better.' Rush to the nearest hospital with a neurology department.
Who Is at Risk?
- Uncontrolled high blood pressure (the #1 risk factor)
- Diabetes
- Smokers (especially bidi/cigarette)
- Heart disease (especially atrial fibrillation)
- Obesity and sedentary lifestyle
- Family history of stroke
- Men over 55, women over 65
Prevention
80% of strokes are preventable:
- Control blood pressure (aim for below 140/90)
- Control blood sugar
- Stop smoking — this single change dramatically reduces risk
- Exercise 30 minutes most days
- Reduce salt intake
- Take prescribed blood thinners if you have atrial fibrillation
Learn FAST. Teach it to your family. In a stroke, you ARE the first responder.
