I agree with kidzpsychapn. Children with Bipolar Disorder are often diagnosed with ADHD and ODD at first. My child was diagnosed in 2nd grade but was not diagnosed with Bipolar Disorder until 6th grade after he had to be hospitalized because his emotions were completely out of his control. Both Stimulants and Antidepressants, can increase Bipolar symptoms. My son had to be taken off of his ADHD medication until the Dr’s were able to stabilize his mood, then after time we were able to reintroduce a low dose of Focalin XR to treat his ADHD. Everyone reacts to medications differently, but we could not use Concerta or Vyvyvanse, they both made him irritable and aggressive. I suggest reading The Bipolar Child by Demitri Papolos, M.D. and Janice Papolos, as well as What Works for Bipolar Kids by Mani Pavuluri, MD, PhD.
