Stroke: What To Do
Interruption of blood supply to part of the brain, from a clot or a bleed.
Last revised
Treatment is time-critical to the hour, which is why the recognition test is a public campaign rather than a clinical one.
Key takeaways
- FAST test: Face, Arms, Speech, Time to call 999
- TIA: symptoms resolve but risk of full stroke is highest in the following days
- Most useful single change: Learn the FAST test and use it without hesitating.
- Commonest mistake: Waiting to see whether symptoms resolve.
- See a doctor if any of the signs under "When to get help" below apply to you.

When to get help
Call 999 immediately for facial drooping, arm weakness, or slurred or confused speech — even if symptoms resolve. A TIA is an emergency because the risk of a full stroke is highest in the following days. Also call 999 for sudden severe headache, sudden vision loss, sudden loss of balance, or sudden numbness on one side.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
