I have a 4yr old boy who was diagnosed this year with ADD. He was evaluated by a neuropsych who gave the diagnosis. She also recommended a neurological eval. We took him to a pediatric neurologist, who suggested he may have PDD/NOS. He can be aggressive at times, especially in school. Gets easily frustrated and at school he starts throwing chairs, would not talk or be very selective with who he talks to. Does not like to transition into different activities unless he wants to. Sometimes he may hide under the table, and come out not remembering why he was there in the first place. I also have a 9 yr old diagnosed with ADHD at age 7. Although he experienced aggressive behavior in the beginning, his behavior is completely different from the 4yr old. We recently moved to US, and all the neuro exams were not finished to rule out or comfirm PDD/NOS on the 4yr old. He gets easily frustrated, can be very head strong and conflictive but also when he wants can be well behaved. He has this emotional outbursts that can be caused by the simplest things. Don't know how to deal with him, we get calls everyday from the preschool to pick him up early because his behavior is too disruptive, aggresive or may be dangerous for the other children. We have tried doing reward chart, but it may work for one day then we are back to square one.
He's had speech therapy and occupational therapy, which needless to say drove us almost bankrupt, it seem to help him a little to focus and to be more tolerant. Now, he is not getting any help and don't know where to get him help here. Went to the Special Ed. Office for my school district to get both boys registered. They said that once they go over the evaluations I provided they will give us a call. For the 9 yr old, they said that it would most likely not be a problem, but the 4 yr old is enrolled on a private preschool so the services would be more difficult to provide.
