I think I first noticed when difficult child was almost 3 years old and going for his upteenth test to see if he was hearing impaired or not, since pediatrician doctor kept saying there was nothing wrong with him. The medication they used to do the test would had knocked out a typical child and many adults, but mine fought it all the way through, after that test and the results of him being deaf, other professionals kept saying that our child was difficult, but none could/would give us any answers. When we moved to PA for the deaf school it seemed he calmed down some and the school always complimented he was an *angel*, what they didn't see was the major tantrums he'd have at home. When he was 7, things got a little more volatile, still nothing at school, in fact when I explained some of the things that were going on at home, the school thought I was talking about a different child. pediatrician docs still said that he seemed more difficult than other children his age and that it wasn't just from his deafness, when we asked about testing though we were blown off. When he was 10, that is when the school finally began seeing what we had been seeing at home for years. The school psychologist didn't feel that difficult child had adhd, but wasn't sure what he had. When he was 11, that was his first stay in psychiatric hospital, they diagnosed him with anxiety not otherwise specified, depression not otherwise specified, odd and Obsessive Compulsive Disorder (OCD). They put him on Klonopin, Lexapro and Abilify. His psychiatrist then added Effexor to the regimen. A few months later he was back in the hospital, a different one this time where they diagnosed him with ADHD. They took him off the Klonopin, Effexor and Lexapro and put him on Concerta and Ritalin, leaving the Abilify there. A few months after, psychiatrist prescribed Remeron to help him sleep. It keeps going to where we are now. We're still looking for answers and correct diagnosis, correct medications, etc.
