What causes stroke?
Stroke is caused by a blockage of blood supply to, or a bleed within, the brain.
How to recognise stroke and transient ischemic attack
- Many people are not aware of the symptoms of stroke or transient ischemic attack (TIA) and often do not go to hospital if either of these events happen.
- Symptoms of stroke are sudden. Common ones include:
- numbness or weakness of face, arm or leg – especially on one side of the body
- vision problems
- loss of coordination
- confusion or trouble speaking or understanding
- severe headache.
- Symptoms of a TIA are similar to stroke, but last only minutes or hours. Only a doctor can tell the difference between a TIA and a stroke. Do not wait to see if it goes away. If someone has the symptoms, phone for emergency medical help immediately.
What to do if stroke happens
- Stroke is a medical emergency. If someone has a stroke, phone for emergency medical assistance urgently.
- Even though the symptoms of a TIA are short-lasting and may not seem severe, a TIA is a medical emergency. Seek medical assistance urgently. Do not wait to see if ‘it goes away’.
Why is stroke a major health issue?
- There are over 13.7 million new strokes each year*. Globally, one in four people over age 25 will have a stroke in their lifetime.**
- Almost 60% of all strokes each year are in people under the age of 70 years.
- 8% of all strokes each year are in people younger than 44 years.
- 52% of all strokes each year occur in men.
- 48% of all strokes each year occur in women. (Source: Global Stroke Fact Sheet, World Stroke Organization)* V. Feigin et al. Global, regional, and national burden of stroke, 1990 to 2016: A systematic analysis for the Global Burden of Disease study 2016. The Lancet Neurology, 2019, forthcoming
