I'm not sure if your evaluation is a full neuropscychological evaluation, but there could be a number of things going on such seeing shades of gray, difficulty with empathy or seeing things from another's point of view, anxiety and a need to have complete order and so on. These difficulties can be related to or as a result of ADHD or other mental health diagnosis.

Often times a child can be taught strategies to deal with these things. For instance how to label problems as very important, medium, and not important so that he can actively think about how he should respond.

Be sure to ask your evaluator to look into this and to address it in the recommendations.
