What Is Stroke?
A stroke happens when blood flow is disrupted in a part of the brain.1 The resulting lack of oxygen damages brain cells, which can have potentially disabling effects on the patient.2

There are two main types of stroke, ischaemic and haemorrhagic, while there is a third more minor stroke called a transient ischaemic attack (TIA).2 An ischaemic stroke can be caused by a blood clot that formed in the heart and travelled to the brain or by atherothrombosis.3 Conversely, haemorrhagic strokes are caused by a rupture in the blood vessels, resulting in bleeding within the brain.2 A TIA is a blood clot that temporarily interrupts blood flow in the brain and is a risk factor for future strokes that could cause more serious damage.1
