the length of the blockage both affect the specific effects of an ischemic

stroke.

ii. Haemorrhagic Stroke

Haemorrhagic strokes occur when a blood artery in the brain ruptures,

producing bleeding into the surrounding brain tissue and account for
around 20% of all strokes (Bamekhlah et al., 2019). This bleeding may

result in more strain on the brain, causing brain cell damage. A

haemorrhage occurs when blood leaks from a blood artery into the
brain tissue. The pressure from the bleeding can harm brain tissue and

put pressure on the brain.

Blood can cause greater tension, compression of adjacent tissues, and
disturbance of regular brain function in the brain tissue. The location,

and amount of the bleeding, as well as the patient's overall condition,

all play a role in how much brain tissue is damaged and how severe the
symptoms are in haemorrhagic strokes. Blood can build up in the brain,

which can cause swelling and inflammation and worsen the injury.
Furthermore, the presence of blood and the outcomes of its breakdown

in the brain tissue can cause inflammation and lead to subsequent harm.

2.1.3 Cause and Risk Factors of Stroke

Understanding stroke causes and risk factors is critical for establishing

effective preventative strategies. There are two types of risk factors,
modifiable and non-modifiable risk factors.
