Approximately 30% of children diagnosed with attention-deficit/hyperactivity disorder (ADHD), the most prevalent mental health disorder in children worldwide, do not respond to conventional pharmaceutical treatments. Most people anyway don't want to deal with allopathic medicine with their wide range of side-effects.  Homeopathy is a safe and proven system of alternative medicine, one of the most popular in the world, which can remove old patterns in a very short period of time. We'd like to focus on concentration and behavioral issues in children.  **** A recent study in Toronto showed that: 1) There was an improvement in ADHD symptoms as measured by the Conner 3 Global Index-Parent T-score in the two groups that received consultations with a homeopathic practitioner when compared with the usual care control group. 2) Parents of the children in the study who received homeopathic consultations also reported greater coping efficacy compared with those receiving usual care. ****
