This disease is a major cause for invalidity and mortality in the world.

  • Strokes are ranked third in the world in regards to mortality.

A stroke is a vascular disorder which occurs in the brain:

  • when a blood vessel ruptures and the blood leaks into the surrounding area, or
  • when a blood vessel becomes blocked and does not allow for the circulation of blood in a particular area of the brain.

A stroke can occur at any time, at any age, but those above 65 years of age are particularly susceptible.

It is possible to recover completely from such a condition, but often patients may suffers from varying degrees of disability.
About 50% of survivors of stroke will suffer from some level of functional disability for around 6 months.
