Overview

A stroke happens when blood flow to part of the brain is blocked or a blood vessel in the brain bursts. Brain cells start to be damaged within minutes, so a stroke is always a medical emergency.

Common symptoms

Sudden drooping or numbness of one side of the face
Sudden weakness or numbness of an arm or leg, usually on one side
Sudden slurred speech or difficulty understanding speech
Sudden loss of vision, dizziness, or loss of balance

Get urgent help if

Any of the symptoms above, even if they go away — call 112 immediately
A sudden, severe headache unlike any before

How doctors evaluate it

An urgent brain scan (CT or MRI) to see whether the stroke is caused by a clot or bleeding
Blood tests, heart rhythm monitoring and blood-vessel imaging

Treatment pathways

For some clot-related strokes, clot-busting medicine or clot removal — these work best when given as early as possible
Treatment of the cause and prevention of another stroke
Rehabilitation: physiotherapy, speech therapy and occupational therapy

Frequently asked questions

Can young people and children have a stroke?

Yes. Stroke is more common in older adults, but it can happen at any age, including in children.

What if the symptoms went away?

Symptoms that go away can be a warning stroke (TIA). It still needs urgent medical assessment.
