The NHS has reminded the public that any sign of a stroke is an emergency and that the first symptom should prompt an immediate call to 999.
In a post on X for World Stroke Day on Thursday, October 29, the health service said the first sign of a stroke might not seem like much, such as being unable to raise an arm, struggling to smile or slurring when speaking. It warned that any sign of a stroke is always an emergency and that at the first sign of face, arm or speech problems, it is time to call 999.
What the FAST test covers
Images shared alongside the post explain the FAST test, which stands for Face, Arms, Speech and Time. The NHS uses the acronym to help people remember three key warning signs and the need to seek emergency assistance.
According to NHS guidance, facial weakness may cause one side of the face to droop when a person tries to smile. Someone having a stroke may also struggle to lift both arms, while slurred or confused speech is another potential sign.
Other symptoms to watch for
Other warning signs listed by the NHS include sudden weakness or numbness on one side of the body, blurred vision or loss of sight. Confusion, dizziness, difficulty finding words and a sudden, severe headache may also occur, although symptoms vary between individuals.
Symptoms can sometimes disappear after a short period, but that does not mean the danger has passed. The NHS explains that a temporary episode may be a transient ischaemic attack, often called a mini-stroke, which needs urgent medical assessment because it can signal an increased risk of a full stroke.
Why early help matters
A stroke occurs when blood supply to part of the brain is interrupted, depriving brain cells of oxygen and nutrients. NHS guidance stresses that rapid treatment can limit the damage, making it important to get emergency help as soon as symptoms appear.
The message from health officials is not to wait for several warning signs to develop or for a person's condition to worsen. If you suspect someone is having a stroke, call 999 and follow the emergency call handler's instructions.
