Stroke: Learn first aid

Learn adult first aid for someone experiencing a stroke including signs, symptoms and what to do in an emergency

What is a stroke?

Strokes are caused by problems in the blood supply to the brain. Brain cells become damaged and begin to die. This brain damage affects the body’s functions, resulting in facial or limb weakness. Sometimes only one limb or one side of the body is affected.

Signs and symptoms of a stroke

Signs and symptoms may include:

  • dribbling from the mouth
  • numbness
  • blurred vision
  • a sudden severe headache
  • difficulty maintaining balance
  • dizziness or feeling light-headed
  • difficulty expressing themselves or understanding other people.

First aid steps for someone having a stroke

1. Use the FAST test to identify a stroke:

  • Face: is there weakness on one side of their face?
  • Arms: can they raise both arms?
  • Speech: is their speech easily understood?
  • Time: to call 999.

Strokes usually happen because of a blockage of the blood supply to the brain. This damages part of the brain, which can affect people’s appearance, bodily functions, speech and sight.

2. Call 999. 

A stroke needs immediate attention. The faster a person having a stroke gets medical help, the less damage there will be.

3. Reassure them while you wait for the ambulance.
