1. Ischaemic stroke (blocked artery)
OR
2. Haemorrhagic stroke (bleed in the brain)
When blood is blocked, the brain cannot get the oxygen it needs, brain cells in the area die and the brain can become permanently damaged. Brain cells usually die within an hour from the beginning of the stroke but can carry on, at times, up to a few hours after the stroke starts. Areas of brain where the blood contribute is reduced but not completely cut off are areas that can survive for some hours. These cells are in a position of shock and can either recover or die depending on what happens in the minutes and hours that follow. Without immediate medical treatment, this area of brain cells will also die.
