It is possible to treat ADHD without drugs. There are a number of natural approaches to help with ADHD, like:
* Behavioural Therapy
* Dietary changes (removing food colourants, food additives, being careful with sugar, taking fish oils)
* See an Osteopath or Chiropractor (hands-on work can help if there is a disruption in the nervous system)
One proven method is behavioral therapy, or what is also referred to as "psychosocial treatment." This approach requires an experienced therapist or educator to teach specific techniques geared toward the child and their parents, as well as the child's teachers and extended family. While these methods are aimed at improving the child's behaviors, they have also been known to improve the child's symptoms and, therefore, some of the resulting problems. Unlike medication, this method takes more time, needs to have goals where achievements are measured in small steps, requires consistency throughout the day in whatever environment the child happens to be (school, home, friend's house, others) and needs to be in force for the "long haul," and not for just a few weeks. 
Another site says, "ADHD treatments that don't involve medication have a proven track record. And here's a surprise: One of the most beneficial options treats the parents, not the child. For children, skills training programs and ADHD summer camps can help teach techniques to overcome everyday problems that often make life miserable, such as remembering to bring assignments home from school or to listen without interrupting.
...Parent skills training has been used for years to improve the behavior of children, and multiple clinical trials have validated its effectiveness. Those same programs improve the behavior of kids with ADHD. Although it may seem odd to be changing parents' behavior to treat what's considered a medical condition in children, research has found that for children with ADHD, having parents who use effective parenting techniques is one of the best predictors of success in adulthood. These programs teach parents to make clear, specific requests of children, for instance, and to use praise and rewards for good behavior far more often than punishment.
Eric Taylor, a professor of psychiatry at King's College Hospital and an ADHD authority who helped write the new standards for the National Institute for Health and Clinical Excellence says that "For milder cases, we recommend starting with behavioral therapy,"
