When stroke strikes, part of your brain shuts down, and so does a part of you. The race to give the best medical treatment starts from the moment 999 is called. Paramedics will take you to the most appropriate hospital, you might have a brain scan, and then the rush will be on to find the best treatment.
The chances are – as in 80 per cent of cases – you will have a blood clot that is blocking the blood flow in your brain. This is called an ischaemic stroke, and every minute 1.9 million neurons and seven miles of axonal fibres die.
