Such instability in a young child can be a challenge when it comes to pinpointing a particular diagnosis. The aggressive behavior, while not out of the question in a child with
AspergerAsperger syndrome's, does not typify
AspergerAsperger syndrome children. The nature and circumstamnces of the angry/aggressive behavior would determine the appropriateness of the O.D.D. diagnosis. In any case, when it comes to medication, the key is to focus on the targets of the medication. It's the symptoms, not the diagnosis, that are the focus of the medication. Since you've had some input already, including a very helpful type of testing, it would make sense to schedule an evaluation with a child psychiatrist. Be sure to share the results of the previous evaluations. Part of your discussion can focus on possible pharmacological interventions.
