A stroke occurs when a problem with the blood supply ascends to the brain. The disturbance can either be the cause of a blood vessel within the brain being ruptured or the blood supply is blocked. This leaves the brain deprived of the essential oxygen and nutrients it acquires to function and survive. Minutes after a stroke, the brain cells begin to disintegrate; this causes a decline in the motor and cognitive abilities in the surrounding area of the brain resulting in a loss of cells. Stroke is a heterogeneous disease with various causes that is diagnosed and divided into a hypernym of cerebrovascular disorders. However, the two major mechanisms causing brain damage in a stroke is caused either by ischemia and infarction of the brain or intracranial haemorrhaging (UK Stroke Association 2015).

The effects following an ischemic attack are fairly rapid due to the brain’s capacity to store glucose; preventing anaerobic metabolism. Less commonly, Strokes that originate from deeply penetrating vessels and cause injury to brain tissue, by disrupting connecting pathways and causing localized pressure injury. These are labelled under the category of haemorrhagic stroke. The UK Stroke Association (2015) states these uncommon numbers fall under 15% of
