A stroke can happen suddenly.

Recognising the warning signs quickly can help a person receive urgent medical assessment and treatment.

One of the easiest ways to remember the main warning signs is FAST:

F — Face
A — Arms
S — Speech
T — Time

Stroke is a medical emergency. The NHS and emergency medical services advise seeking emergency help immediately when stroke symptoms occur.

What Is a Stroke?

A stroke occurs when blood supply to part of the brain is interrupted, or when bleeding occurs in the brain.

Because brain tissue depends on a continuous supply of oxygen and nutrients, a stroke requires urgent assessment.

There are different types of stroke, and the treatment depends on the type and timing.

Remember FAST

F — Face

Ask the person to smile.

Look for:

• Drooping on one side of the face
• A crooked smile
• Difficulty moving one side of the face

Sudden facial weakness can be a warning sign of stroke.

A — Arms

Ask the person to raise both arms.

Look for:

• Weakness in one arm
• Numbness
• One arm drifting downward
• Difficulty lifting or holding one arm up

Sudden one-sided arm weakness is another key warning sign.

S — Speech

Ask the person to speak.

Listen for:

• Slurred speech
• Difficulty speaking
• Difficulty finding words
• Difficulty understanding speech
• New confusion

Sudden speech difficulties can occur with stroke.

T — Time

If any of these symptoms appear suddenly, time matters.

Do not wait to see whether the symptoms improve.

Seek emergency medical care immediately.

Other Possible Stroke Symptoms

FAST covers the most commonly recognised signs, but stroke can cause other sudden symptoms, including:

• Numbness or weakness on one side of the body
• Sudden vision loss or blurred vision
• Sudden confusion
• Difficulty understanding speech
• Sudden dizziness
• Difficulty walking or maintaining balance
• A severe headache
• Nausea or vomiting

These symptoms can have other causes, but sudden neurological symptoms require urgent assessment.

What If the Symptoms Go Away?

Do not assume that everything is fine simply because the symptoms disappear.

A transient ischaemic attack, or TIA, can produce stroke-like symptoms that resolve after a short period.

The symptoms of a TIA can resemble those of a stroke, and urgent medical assessment is still important.

A TIA can be a warning that a person is at increased risk of a future stroke, so it should never be ignored.

What Should You Do If You Suspect a Stroke?

If you recognise sudden FAST symptoms:

1. Seek emergency medical help immediately

Do not wait for symptoms to disappear.

2. Note when the symptoms started

The timing of symptom onset can be important to medical professionals.

If you don’t know the exact time, tell the emergency team when the person was last known to be well.

3. Do not delay for a routine appointment

A suspected stroke requires emergency evaluation rather than a normal clinic appointment.

4. Follow emergency medical instructions

Emergency professionals can advise what to do while help is being arranged.

Why Does Timing Matter?

Stroke treatment can be time-sensitive.

The sooner a stroke is assessed, the sooner clinicians can determine whether emergency treatment is appropriate.

This is why the final letter in FAST is T for Time.

It is not about diagnosing the stroke yourself. It is about recognising a potential emergency and getting the person to appropriate medical care quickly.

Who Is at Higher Risk of Stroke?

Stroke risk can be influenced by factors such as:

• High blood pressure
• Diabetes
• High cholesterol
• Smoking
• Certain heart conditions
• Previous stroke or TIA
• Increasing age
• Other medical and lifestyle factors

Having a risk factor does not mean that a person will necessarily have a stroke.

Managing recognised risk factors and following appropriate medical advice can be an important part of preventive care.

Can a Health Check-Up Help With Stroke Prevention?

A health check-up cannot predict or prevent every stroke.

However, preventive assessments can help identify certain cardiovascular and metabolic risk factors, such as high blood pressure, diabetes or abnormal cholesterol levels, which can then be managed appropriately.

The aim is not simply to collect test results. It is to identify health risks and discuss appropriate next steps with a healthcare professional.
