Despite the virtual elimination of this lack of oxygen (asphyxia), infection, trauma, malnutrition, cause of CP in the last few decades, CP rates have not drugs or other chemicals, or hemorrhage.

It was once thought that difficult or prolonged delivery was Prematurity is one of the most significant risk fac- responsible for many cases of CP, but most researchers tors for CP. About 7% of babies weighing less than three now believe that the great majority of cases result from pounds at birth develop CP, and the risk increases dra- brain damage occurring before birth. Prematurity may increase the damages the motor areas can harm other areas as well, risk of CP because of the increased likelihood of hemor- leading to problems commonly associated with CP. Brain hemorrhage is most common in babies weighing If brain cells do not get enough oxygen because of less than four pounds at birth, and the risk increases as poor circulation, they may die.

Even before the discovery of America by Euro- peans, Native Americans used powdered charcoal mixed For acute poisoning, the dosage is as follows: with water to treat an upset stomach. Now charcoal is • infants (under 1 year of age): 1 g/kg being rediscovered as an alternative treatment for this • children (1-12 years of age): 15-30 g or 1-2 g/kg with condition.
