What is a stroke?
A stroke is a serious medical and potentially life-threatening emergency caused when something interrupts or stops the blood supply to the brain.
If you suspect someone is having a stroke, use the following NHS advice FAST to check for symptoms and call for help.
The main symptoms of stroke can be remembered with the word F.A.S.T.:
- Face – the face may have dropped on one side, the person may not be able to smile, or their mouth or eye may have dropped.
- Arms – the person with suspected stroke may not be able to lift both arms and keep them there because of weakness or numbness in one arm.
- Speech – their speech may be slurred or garbled, or the person may not be able to talk at all despite appearing to be awake.
- Time – it's time to dial 999 immediately if you see any of these signs or symptoms.
Time really is a key factor in how serious the stroke survivor may be affected. The faster you get help, the better their chances of a good recovery.
