Stroke

Stroke is an abrupt interruption of constant blood flow to the brain causing a loss of neurological function. This may be due to blockage or bleeding. The former causes the more common ischemic stroke which causes about 87% of all strokes. The latter causes the haemorrhagic stroke which, although rarer, is considered infinitely more dangerous.

Often there is very little warning of an impending stroke but the effects of it can be debilitating to fatal. Starved of blood flow, brain cells which require constant oxygen and nutrients can be damaged or even die within minutes. Once dead, brain cells typically don’t regenerate and this can result in mental and even physical diasbilities. Thus, it is of vital importance that oxygen and blood flow be restored as quickly as possible.
