Brain Stroke: A Complete Guide to Causes, Treatment and Recovery

The Two Main Types of Stroke

Most strokes are ischaemic — a clot blocks an artery feeding the brain. A smaller proportion are haemorrhagic — a blood vessel bursts and bleeds into or around the brain. The two are treated very differently, which is why an urgent brain scan is the first step: giving the wrong treatment can be harmful. A "mini-stroke" or TIA is a temporary warning that must never be ignored.

Recognising Stroke: The FAST Test

FAST captures the commonest signs: Face drooping on one side, Arm weakness, Speech that is slurred or strange, Time to call emergency immediately. Sudden numbness, confusion, trouble seeing, severe headache or loss of balance can also signal stroke. Our detailed FAST test guide walks through each sign.

The Golden Window and Emergency Treatment

For ischaemic stroke, treatments to reopen the blocked artery — clot-dissolving medication and, for large clots, mechanical clot removal (thrombectomy) through a catheter — work best within a limited time window from symptom onset. The earlier treatment begins, the more brain is saved. This is why "wait and see" is the most dangerous response to stroke symptoms.

Preventing a Stroke Before It Happens

Most strokes are preventable. The key measures: control blood pressure — the single biggest risk factor; manage diabetes and cholesterol; stop smoking; treat atrial fibrillation (an irregular heart rhythm that throws clots to the brain) with the right medication; and stay active. Many people carry a silent, treatable risk — an irregular heartbeat or a narrowed neck artery — that can be found and managed before it ever causes a stroke.

What Thrombectomy Means for Major Strokes

For a stroke caused by a large clot, mechanical thrombectomy — physically removing the clot through a catheter threaded up to the brain artery — has transformed outcomes over the last decade. Performed by an interventional neurology team within the treatment window, it can restore blood flow and dramatically reduce disability in strokes that clot-dissolving medicine alone cannot fix. Access to this capability is a defining feature of a genuine stroke centre.

Why a Specialised Stroke Centre Matters

Stroke outcomes depend on speed and expertise — rapid scanning, a team ready to deliver clot-busting treatment or thrombectomy, and neuro-critical care afterwards. Health1's interventional neurology programme is built around this pathway, led by a US-trained stroke specialist.

Recovery and Rehabilitation

Recovery varies widely — some regain function quickly, others need months of rehabilitation involving physiotherapy, speech therapy and occupational therapy. The brain's ability to relearn is real, and structured rehabilitation started early makes a meaningful difference. Preventing a second stroke — controlling blood pressure, diabetes, and heart rhythm — is part of the plan.
