Prior to our doctor consulting with Dr. Matthews, we had tried numerous medications, therapies, discipline strategies, and none of them seemed to be making an impact. Within months of working with Dr. Matthews, I had my sweet, lovable boy back. In the past year he's gone from being incapable of being in a public school environment to thriving. Our entire family has changed for the better. I would recommend any family of a child with DMDD to have cognitrace testing done and consult with him. It has made a world of difference.
