It consists of an abnormal connection between an artery, vein, or both and includes venous angiomas and arteriovenous malformations. These malformations can irritate the surrounding brain tissue and cause seizures and headaches. If the malformation ruptures, it will bleed into the brain.

A TIA occurs when there is a temporary disruption in blood flow to the brain. Approximately 30 percent of all people who suffer a stroke experience a stroke first.

A sudden, severe and unusual headache can be a warning sign for a hemorrhagic stroke and requires immediate medical attention.
