I had difficulty getting a diagnosis for my son. I ended up paying out of pocket for consultation at the Amen Clinic (run by Dr. Daniel Amen of PBS fame). We did the full SPECT brain imaging. We started with natural supplements and within the year transitioned to medications. We are still struggling to achieve a balance with the medications, but remain connected to a psychiatrist that understands the disease and is knowledgeable about treatments. it was an expensive option, but finally gave us answers.
