What is a stroke?

A stroke occurs an area of the brain is deprived of oxygen, either as the result of a burst blood vessel or because a blood vessel has become blocked by a blood clot.

Causes of a stroke

Atherosclerosis or hardening and narrowing of the arteries causes an ischaemic stroke and a haemorrhagic stroke occurs when an artery inside the brain suddenly starts bleeding (cerebral haemorrhage).

Symptoms of a stroke

It is incredibly important to be able to identify the symptoms of a stroke to ensure that the victim receives medical attention as soon as possible.

Diagnosing a stroke

Quick diagnosis of a stroke is important to minimise long-term or permanent damage and to identify the affected areas of the brain.

Treating a stroke

Many patients who have suffered a stroke may need to be hospitalised immediately. Sometimes emergency neurosurgery is necessary to remove blood clots or to repair a ruptured aneurysm. Rehabilitation may be necessary.
