STROKE

DEFINITION

Stroke is the common term is used to describe a condition in which the blood supply to part of the brain is suddenly and seriously impaired by a blood clot (cerebral thrombosis) or a ruptured artery (cerebral haemorrhage).

Strokes are more common in later life, and in those who suffer from high blood pressure, or some other circulatory disorder.  The effect of a stroke depends on how much, and which part, of the brain is affected.  If a series of small blood vessels (micro-aneurisms) rupture at different times, there is progressive disability.  Rupture of a large blood vessel may cause extensive loss of function.  Major strokes can be fatal, but many people make complete recoveries from minor strokes.

The effects of strokes can include paralysis of a limb or one side of the body and disturbances in speech and vision.  A stroke suffered on the right side of the brain will affect the left side of the body and vice versa.
