Around 16,000 people in Switzerland suffer a stroke every year. Around one in four sufferers is no longer able to lead an independent life following a stroke. A stroke may be caused by a narrowing of the carotid artery or cerebellar artery, a blockage in the blood vessels or a brain haemorrhage. Particularly at risk are people with high blood pressure or special forms of cardiac arrhythmia (atrial fibrillation). Factors such as drinking, smoking and diabetes can result in a stroke because they lead to calcification of the arteries.
Because every second counts when someone has a stroke, it’s very important to recognise the symptoms correctly. Acting quickly can save lives and prevent long-term disability.
How do I recognise the signs of stroke?
The symptoms of a stroke commonly include problems seeing, speaking or understanding, paralysis and numbness, headache and dizziness.
Even if you have no medical knowledge you can do an easy test to check whether the symptoms indicate a stroke. If you suspect someone is having a stroke, ask them to
- raise their arms
- speak a very simple sentence (e.g. “the weather is fine”)
If they have problems with any one of these tasks you must call an ambulance immediately. Until the ambulance arrives, make sure the person’s lying comfortably with their upper body raised. They shouldn’t eat or drink anything, as a stroke can often lead to problems swallowing. It’s very important for family members to keep calm.
