- 2. Hemorrhagic Stroke

Hemorrhagic stroke occurs when a blood vessel in the brain leaks or ruptures. Intracerebral bleeding may result from several conditions that affect the blood vessels. Factors associated with hemorrhagic stroke include:

Uncontrolled hypertension.

Excessive anticoagulant therapy (blood-thinning medications).

Bulging at weak points in blood-vessel walls, known as aneurysms.

Head injury, such as trauma caused by a motor-vehicle accident or a blow to the head.

Protein deposits within blood-vessel walls that weaken the vessel, known as cerebral amyloid angiopathy.

Hemorrhagic transformation of an ischemic stroke. A less common cause of intracerebral bleeding is rupture of an arteriovenous malformation (AVM), an abnormal tangle of thin-walled blood vessels.
