It is a type of ischemic stroke resulting from a blockage in the blood vessels supplying blood to the brain. It can be atherothrombotic or embolic. Stroke caused by cerebral infarction should be distinguished from two other kinds of stroke - cerebral hemorrhage and subarachnoid hemorrhage. The symptoms are determined by the parts of the brain affected which include:
1. weakness and loss of sensation on the opposite side of the body
2. abnormal pupil dilation
3. light reaction
4. lack of eye movement on opposite side
5. speech will be slurred if the infarction is on the left side of the brain
HOW IS CEREBRAL INFARCTION DIAGNOSED?
A neurologist diagnoses cerebral infarction by using the following imaging tests of the brain:
1. CT Scan
2. MRI scan
HOW IS CEREBRAL INFARCTION TREATED?
Intravenous rtPA therapy is usually used by the neurosurgeon to treat this condition. Also, the doctor may prescribe thrombolytic drugs. Further, stents and angioplasty have also emerged as possible treatments for this condition. A carotid endarterectomy can also help in decreasing the risk of infractions by surgically removing the stenosis.
