What are the major types of hemorrhagic strokes?
Hemorrhagic strokes include subarachnoid hemorrhage (SAH, usually due to aneurysm rupture) and parenchymal intracerebral hemorrhage (ICH).
Overall, approximately 6% of strokes are due to deep ICH, 3% are due to lobar ICH, and 3% are due to SAH. Although ischemic strokes are more frequent, hemorrhagic strokes have a higher morbidity and mortality.
Because subdural and epidural hematomas are extra-axial, these bleeds are not considered strokes
