Ischaemic stroke
Definition:
The most common subtype of stroke; Ischaemic stroke is triggered by a sudden blood circulation loss to areas of the brain, which corresponds to a loss of neurologic function. This occurs when an artery to the brain is blocked. The two main causes of Ischaemic stroke are thrombosis – when the blood clot is formed within the brain, and embolism – when the clot is formed elsewhere. (The internet stroke center)
(Blood clot deprives the brain of oxygen and important nutrients)
Incidence & risk factors:
Accounting for nearly 88 percent of all type of strokes, Ischaemic stroke is by far the most common (American Heart association, 2014). In Australia, ischaemic …show more content…

The major risk factors for intracerebral haemorrhage includes:
- Age: As intracerebral haemorrhage occurs more frequently with advanced age
- Race: ICH is more common with African Americans and Japanese than other racial groups
- Sex: ICH sufferers are slightly more often male than female
- Hypertension (high blood pressure): As an elevation of blood pressure may easily cause the rupture of the tiny arteries inside the brain.
- Tumor: Angiomas and metastatic are both highly vascularized tumors which are able to bleed into the brain tissue
- Problems with the arterial wall: e.g Amyloid angiopathy (a degenerative disease of arteries) or Aneurysm (weakening of arterial walls)
- Drug usage
(Zuccarello, 2013)
Acute presentation & diagnosis:
Prognosis:
Intracerebral haemorrhage has a high rate of morbidity and mortality as more than one third of the patient suffering from intracerebral haemorrhage will pass away with only 20 % of patient regaining full functional independence. (Counsell C, …show more content…
