I63: Cerebral infarction

Cerebral infarction, also known as a stroke, is a group of conditions that occur when the blood supply to a part of the brain is interrupted or severely reduced, depriving brain tissue of oxygen and nutrients. This can result in brain cells dying within minutes. Cerebral infarctions are often caused by a clot blocking the flow of blood in a vessel inside the brain, or by a vessel in the brain rupturing. This can result from health problems like high blood pressure, obesity, high levels of cholesterol, and conditions that make the blood more likely to clot, like atrial fibrillation. Common symptoms include weakness, lack of coordination, difficulty speaking, loss of vision, and severe headaches. The progression of the condition depends on the site and size of the infarction. Effects can range from minor alterations to significant impairment in bodily functions or even death. A cerebral infarction primarily affects the brain, but it can also affect the entire central nervous system and have long term effects on physical and mental abilities.
