Homeopathic treatment of children with attention deficit hyperactivity disorder: a randomised, double blind, placebo controlled crossover trial
An increasing number of parents turn to homeopathy for treatment of their hyperactive child . Two publications , a r and omised , partially blinded trial and a clinical observation study , conclude that homeopathy has positive effects in patients with attention deficit hyperactivity disorder ( ADHD ) . The aim of this study was to obtain scientific evidence of the effectiveness of homeopathy in ADHD . A total of 83 children aged 6–16 years , with ADHD diagnosed using the Diagnostic and Statistical Manual of Mental Disorders-IV criteria , were recruited . Prior to the r and omised , double blind , placebo controlled crossover study , they were treated with individually prescribed homeopathic medications .  62 patients , who achieved an improvement of 50 % in the Conners ’ Global Index ( CGI )  , participated in the trial . Thirteen patients did not fulfill this eligibility criterion ( CGI ) . The responders were split into two groups and received either verum for 6 weeks followed by placebo for 6 weeks ( arm A ) , or vice-versa ( arm B ) . At the beginning of the trial and after each crossover period , parents reported the CGI and patients underwent neuropsychological testing . The CGI rating was evaluated again at the end of each crossover period and twice in long-term follow-up . At entry to the crossover trial , cognitive performance such as visual global perception , impulsivity and divided attention , had improved significantly under open label treatment ( P<0.0001 ) . During the crossover trial , CGI parent – ratings were significantly lower under verum ( average 1.67 points ) than under placebo ( P = 0.0479 ) . Long-term CGI improvement reached 12 points ( 63 % , P < 0.0001 ) . Conclusion : The trial suggests scientific evidence of the effectiveness of homeopathy in the treatment of attention deficit hyperactivity disorder , particularly in the areas of behavioural and cognitive functions
