It's shocking how much superstition can make it into what should be a more formalized method of treatment. ADHD is a quantifiable proven phenomenon. If someone you trust to be a positive influence to your health doesn't "believe" in it, they don't have a reliable method of sense-making and generally shouldn't be thought of as an authority. They lack they ability to be authoratative about anything except by councidence because they lack the ability to base their claims on reliable evidence since that appears not to be a factor for them.
