CARE, RECOVERY & REHABILITATION
Understanding the Golden Hour in Stroke Care
By Dr Aarati Kulkarni
Imagine you’re driving to work when the person beside you suddenly says their arm feels weak. Their smile looks uneven. They try to speak, but the words come out slurred and confused. It may last only a few seconds, but what happens next could determine whether they make a full recovery or live with permanent disability.
This is where the Golden Hour comes into play.
Doctors often say, “Time is Brain.” It’s not just a slogan—it’s a medical reality. During an ischaemic stroke, which accounts for nearly 85% of all strokes, a blood clot blocks the supply of oxygen-rich blood to a part of the brain. Brain cells begin to die within minutes. Researchers estimate that almost two million brain cells are lost every minute a stroke goes untreated. The longer treatment is delayed, the greater the loss of brain function.
The Golden Hour refers to the first hour after stroke symptoms begin. This is the most critical period for recognising the warning signs, calling for emergency medical help, reaching a hospital equipped to treat stroke, undergoing brain imaging and beginning appropriate treatment. Although clot-busting medicines (thrombolysis) may be given up to 4.5 hours after symptom onset in selected patients, and mechanical clot removal (thrombectomy) may benefit certain patients even later, earlier treatment almost always leads to better outcomes. Every minute saved improves the chances of preserving brain tissue, reducing disability and returning to an independent life.
So how do you recognise a stroke quickly?
Remember the simple B.E.F.A.S.T. test:
- B – Balance: Sudden loss of balance or coordination.
- E – Eyes: Sudden blurred vision or loss of vision in one or both eyes.
- F – Face: One side of the face droops or feels numb.
- A – Arm: Weakness or numbness in one arm or leg.
- S – Speech: Slurred speech or difficulty understanding words.
- T – Time: Time to call emergency medical services immediately.
One of the biggest mistakes people make is waiting to see if the symptoms improve. Some strokes begin with mild or temporary symptoms, but delaying medical care can mean missing the opportunity for life-saving treatment. Never try to drive yourself to the hospital if an ambulance is available, and never ignore symptoms simply because they disappear after a few minutes. Even a brief episode may be a Transient Ischaemic Attack (TIA)—often called a “mini-stroke”—which is a serious warning that a major stroke could follow.
At ASTRA Stroke India Foundation, our message is simple: Don’t wait. Don’t watch. Act immediately. Learn the B.E.F.A.S.T. signs, know the nearest Stroke-Ready Hospital in your area, and encourage your family, friends and colleagues to do the same. Every minute counts. Acting within the Golden Hour can mean the difference between recovery and lifelong disability, between independence and dependence, and in many cases, between life and death.
Remember: Time is Brain. The sooner treatment begins, the greater the chance of saving both the brain and the person.
