Stroke, also called brain attack, cerebral infraction or cerebrovascular accident (CVA), is a very serious condition in which the entire brain or some parts of it stop functioning due to disturbance in the blood supply. This can be due to ischemia (an obstruction in the vessels) or due to haemorrhage (bleeding in to the brain cranial cavity). As a result, a part of the brain stops functioning properly, which may result in difficulty or inability to move limbs or the entire side of the body. The patient may also feel difficulty in understanding or formulating speech.

An aneurysm is a medical condition caused by abnormal widening of an artery, anywhere in the body, due to the weakness in the walls of the blood vessels. Aneurysm mostly occur in the cerebral vessels, the abdominal aorta and popliteal arteries. When cerebral vessels are affected, it is called a subarachnoid haemorrhage as it gives symptoms similar to a stroke. The management of a ruptured aneurysm depends on the location of the affected vessels but it mostly requires medical management with surgical intervention.
