Ischemic versus hemorrhagic stroke


The clotting or bleeding events that affect the blood flow to the brain are known as strokes. There are commonly 2 types of strokes, one is ischemic stroke and another is hemorrhagic stroke. (, 2021).

Ischemic stroke:

An Ischemic stroke happens when there is a blockage of blood vassal of the neck and brain. The blockage can occur due to blood clotting in the neck and brain which is commonly known as thrombosis. Embolism is another reason for Ischemic heart stroke where the blood clot travels from the heart to the brain. Stenosis can also cause ischemic stroke where there is a narrowing of the artery that can be seen heading to or in the brain. The 5 signs and symptoms of ischemic stroke are dizziness, severe headache, balance loss, weakness, speaking, and understanding problems (Randolph, 2016, p.1).

Hemorrhagic stroke:

A hemorrhagic stroke happens when there is bleeding into the brain due to the rapture of blood vassal. The two subdivisions of hemorrhagic stroke are subarachnoid and intracerebral hemorrhage. Bleeding into the brain parenchyma is commonly known as intracerebral hemorrhage. When there is bleeding into subarachnoid space that is commonly known as subarachnoid hemorrhage.

The most common reason for hemorrhagic stroke is hypertension. Prolonged hypertension causes elastic lamina breakage, media degeneration, and smooth muscle fragmentation of the arteries. In older adults, another important reason for intracerebral hemorrhage is cerebral amyloid angiopathy. It causes when the amyloid-beta peptide is deposited in arterioles, capillaries, and other arteries of the cerebellum and cerebral cortex. Smoking Cigarettes, cerebral microbleeds, and chronic liver disease are the other causes of hemorrhagic stroke. The symptoms of this kind of stroke are headache, facial palsy, aphasia, and hemiparesis (Unnithan & Mehta, 2021, p.2).


To avoid further disability and severity of the stroke, immediate action is required. For the categorization of the stroke, the doctors generally suggest a computerized tomography scan or other brain imaging.
