My son is 10. He was thought to be ADHD from ages 5-8. He had tics at age 7 and was diagnosed with Tourette. He went to a psychiatrist in So CA and was referred to the Amen Clinic in Newport Beach where his primary diagnosis was changed according to his SPECT scan to Bipolar Disorder, with ADHD, Sensory Integration issues, Obsessive Compulsive Disorder and Autistic Spectrum Disorder. Yep! they are all related.
