William Walsh, PhD, in his book Nutrient Power:  "The reality is that most children with terrible behavior were born with chemical imbalances that predispose them to this conduct.  Flawed life circumstances can aggravate this condition, but the underlying cause is usually bad chemistry.  The best way to reduce crime and violence is to identify children with antisocial tendencies and to provide effective treatment before their lives are ruined.  Until this capability is achieved, behavior-disordered children will continue to develop into criminals and our nation's horrific rate of crime and violence will persist . . ."  Giving psychotropic medications, especially to children, is not the best solution.  Resources spent properly diagnose and treat children's underlying disorders such as methylation, pyrrole, or copper overload could prevent issues later on.   http://www.walshinstitute.org/nutrient-power.html & http://www.mensahmedical.com/.
