Stroke

Stroke is another name for cerebral infarction (blood clot in the brain) and cerebral hemorrhage, in which cerebral infarction dominates with roughly 85% of the cases.

As a result, the affected area of the brain does not function normally, which can lead to paralysis, inability to understand or formulate speech, seeing things with impaired quality of life and ability to fend for himself.

In 2014, 33 million people worldwide had a stroke, of which nearly 17 million consisted of people who had their first stroke1. Stroke is the second biggest cause of death worldwide after heart attacks and amounts to more than 11 percent of deaths in the world. Stroke is the leading cause that disability occurs.2 In the United States a person suffers a stroke every 40 seconds3. In 2014, 27,500 people had an acute cerebral infarction in Sweden.4

Cerebral infarction (ischemic stroke) is a thrombosis-related damage in the brain caused by lack of oxygen that provides acute shortage of blood supply to all or parts of the brain. The infarction may be either thrombotic which means that it is caused by a blood clot formed in the brain or embolic which means that it is caused by a blood clot formed elsewhere but got stuck in a blood vessel in the brain.
