Cerebral thrombosis is caused by a blood clot blocking an artery supplying the brain that occurs in the brain itself.

Cerebral embolism is caused by a blood clot blocking an artery supplying the brain that forms elsewhere in the circulatory system that breaks free. It is commonly cause by atrial fibrillation.

Intracerebral hemorrhage occurs when a blood vessel within the brain itself breaks either from trauma or excess internal pressure.

Subarachnoid hemorrhage occurs when a blood vessel at the brain surface just below the arachnoid membrane breaks either from trauma or excess internal pressure.

What else can I help you with?
