Stroke Main page

An Ischaemic Stroke occurs when there is a blood clot in one of the blood vessels and this blocks of the blood supply to a part of brain. Population based studies will suggest that about 2/3rds (68%) of all strokes are Ischaemic in nature.

It is important to note that despite the lack of blood supply that part of the brain does not immediately die; instead it remains in a state of shock but still viable and is still able to recover for up to a period of 4.5 – 6 hours. If within this time period the blood supply to the brain can be restored (Treatments are available at specialist centres) then the damage and brain death can be limited and reversed to certain extent.
