When my son, Joey, was in high school he had very challenging behavior. He has autism; diagnosed at age two with classic infantile autism (now referred to as Level 3 – the most severe form of autism). At age 11 he acquired the additional diagnosis of Bi-Polar Disorder (rapid cycler). This dual diagnosis, along with the frustrations of being non-verbal and fluctuating hormones resulted in destructive and self-injurious (headbanging) behavior. In fact, he never attended school for longer than 3 hours a day.
