In brief: High blood pressure
Most commonly high blood pressure (hypertension), which puts a toll on small brain blood vessels which can rupture and bleed, usually at older age.
Other causes include brain aneurysms, vascular malformations, tumors, head injury, amyloid angiopathy, use of stimulants including street drugs, medications such as blood thinners, brain surgery, cerebral venous thrombosis etc.
