    Cerebral Vascular Accident (CVA) is one of the most common causes of death and the most common cause of disability in the western world. It is the largest killer in the age group of 65 and over. Stroke occurs when there is a sudden disruption to the brain’s blood supply and brain cells are affected by the lack of oxygen. Unlike other organs, the brain is more susceptible to oxygen shortage therefore cells will start dying within minutes causing irreparable damage. There is no such thing as a typical stroke, each casualty will present with different recognition features.

    below are a few causes,
    • Cerebral artery blockage – due to blood clot (most common cause), fat, air or foreign material.
    • Cerebral artery rupture – due to haemorrhage into the brain tissue (least common cause).

    Recognition features

    • Numbness, weakness or paralysis of the arms and/or legs, localised to one side of the body.
    • Drooling and difficulty with speech.
    • Visual disturbances.
    • Loss of bladder and bowel control.
    • Severe headache.
    • Flushed warm skin.
    • Alteration in levels of consciousness.
    • Pupils unequal in size.
    • Irregular breathing and slow, strong pulse.
