Overview
A stroke happens when part of the brain does not get enough blood, either because a vessel is blocked (ischaemic stroke) or because it bleeds (haemorrhagic stroke). Brain cells begin to die within minutes, so fast treatment is critical.
Recognise a stroke: BE FAST
- Balance: sudden loss of balance
- Eyes: sudden loss of vision
- Face: drooping on one side
- Arms: weakness or numbness in one arm
- Speech: slurred or strange speech
- Time: get emergency help immediately
Causes and risk factors
- High blood pressure
- Diabetes and high cholesterol
- Atrial fibrillation
- Smoking
- Older age and a family history of stroke
Diagnosis
An urgent CT or MRI scan of the brain shows the type of stroke. Further tests look for the cause, such as heart rhythm monitoring and scans of the blood vessels.
Treatment
Treatment depends on the type of stroke and how quickly the patient reaches hospital. It may include clot-dissolving medicines, procedures to remove a clot, or control of bleeding. Rehabilitation helps people regain lost function.
When to see a doctor
