                          CIRCULATION - STROKE
   ----------------------------------------------------------------------

   This term is used to describe a condition in which the blood supply
   to part of the brain is suddenly and critically impaired by a blood 
   clot ( Cerebral Thrombosis ) or when a ruptured artery leaks blood
   into the brain ( Cerebral Haemorrhage ). The latter is more likely
   in people who have high blood pressure. In either case, the affected
   brain cells cease to function altogether.

   Each area of the brain controls a different system or part of the 
   body and any deficiency resulting from a Stroke depends on how much,
   and which part of the brain is affected.

   Major Strokes are often fatal, but many people make sucessful 
   recoveries from minor Strokes.

   Strokes are more common in people over 55, in those who are known
   to suffer blackouts or circulatory disorders or in those who have
   had previous Strokes.
 
   N.B. The Signs and Symptoms may be confused with drunkeness.


   Depending on the severity of the Stroke, one or more of the following
   physical defects may be apparent:


   Paralysis of the mouth - the corner of the mouth may droop, saliva
   may dribble from it, and speech is often slurred.

   Weakness and decreased sensation in one or both limbs and on one 
   side of the body.

   Flushed face with hot dry skin.
 
   Pupils may be unequally dilated.

   Loss of bowel and bladder control.


   Treatment
   ---------

   1:  If conscious, lay the casualty down with the head and shoulders
       slightly raised and supported. Position the head on the side to
       allow saliva to drain from the mouth

   2:  Loosen any costricting clothing around the neck, chest and waist
       to assist circulation and breathing.

   3:  If casualty becomes unconscious place in the Recovery Position.
       ( See diagram - and section Resusitation )

   4:  If breathing and heartbeat stop begin Resusitation immediately.

   5:  Remove to Hospital immediately. Transport as stretcher case
       maintaining the treatment position.
