Cerebral infarction
Cerebral Infarction
Cerebral infarction (pronounced: /səˈriːbrəl ɪnˈfɑːrkʃən/) is a type of stroke that results from the blockage or narrowing of the blood vessels supplying blood and oxygen to the brain.
Etymology
The term "cerebral infarction" is derived from Latin, where "cerebrum" refers to the brain and "infarction" means tissue death due to lack of oxygen.
Causes
Cerebral infarction is most commonly caused by atherosclerosis, a condition where the arteries are narrowed by fatty deposits. Other causes include embolism, where a blood clot or other particle forms in one part of the body and travels to the brain, and thrombosis, where a blood clot forms in an artery that supplies the brain.
Symptoms
Symptoms of cerebral infarction can vary depending on the area of the brain affected, but may include sudden numbness or weakness of the face, arm, or leg, especially on one side of the body, sudden confusion, trouble speaking or understanding speech, sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, loss of balance or coordination, or sudden severe headache with no known cause.
Treatment
Treatment for cerebral infarction aims to restore blood flow to the brain as quickly as possible to minimize damage. This can be achieved through medication, such as thrombolytics, which dissolve blood clots, or through procedures such as angioplasty and stenting, which open up blocked arteries.
Prevention
Prevention of cerebral infarction involves managing risk factors such as high blood pressure, diabetes, and high cholesterol, as well as lifestyle changes such as quitting smoking, eating a healthy diet, and getting regular exercise.
