Detailed explanation-1: -Hemorrhagic stroke is due to bleeding into the brain by the rupture of a blood vessel. Hemorrhagic stroke may be further subdivided into intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Hemorrhagic stroke is associated with severe morbidity and high mortality.

Detailed explanation-2: -Intracerebral haemorrhage (ICH) is where blood leaks out of a blood vessel into the brain tissue, sometimes deep inside the brain. ICH is the most common type of haemorrhagic stroke, and around two thirds of all haemorrhagic strokes are ICH.

Detailed explanation-3: -A hemorrhagic stroke happens when an artery in the brain leaks blood or ruptures (breaks open). The leaked blood puts too much pressure on brain cells, which damages them.

Detailed explanation-4: -A hemorrhagic stroke occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels usually cause hemorrhagic stroke: aneurysms and arteriovenous malformations (AVMs).
