Stroke (TIA)

A stroke, also known as a TIA (transient ischemic attack), occurs when the blood supply to part of the brain is suddenly interrupted. As a result, brain cells do not receive enough oxygen and nutrients, causing them to become damaged or die within a short period of time. Prompt medical treatment is essential to minimise the risk of permanent brain damage.

There are two main types of stroke:

  • Ischemic stroke: A blood vessel in the brain becomes blocked by a blood clot. This is the most common type of stroke.
  • Hemorrhagic stroke: A blood vessel in the brain ruptures, causing bleeding into the brain tissue.

The symptoms that remain after a stroke vary depending on which part of the brain has been affected.
