Recognising a Stroke

When a person suffers a stroke, the blood supply to their brain tissue has been stemmed and cells die due to lack of oxygen.  This can cause brain damage and possibly death.

A stroke occurs when the brain tissue is starved of oxygen.  When you have high blood pressure, your heart must make a sustained effort to ensure blood is circulated around the body.  This puts added strain on your heart, and the blood vessels that supply all body tissue; including the vessels that supply oxygen to your brain.  The continual strain on blood vessels can cause them to become clogged up or weaken, which can in turn lead to narrow blood vessels and blood clots.

When a blood clot forms a blockage in an artery leading to the brain, or in a blood vessel inside the brain, it can result in a stroke or transient ischaemic attack (TIA or ministroke).

Whilst strokes are more common in over 65's, they do still occur in any age group.  A number of factors can make you more likely to have a stroke, including:

  • Smoking
  • Obesity
  • Poor diet
  • Excessive alcohol consumption
