My son has been given a diagnosis of CDD before and PDD before that but the truth is he has GERD and reacts to wrong food so I keep him on a special diet. He still though seems to have digestive issues now and then and they affect his behavior. I am wondering if there is something someone has missed. He is not the same in communication skills and/or as pleasant as he used to be and sometimes it seems to come back occasionally. He has lost fine motor skills but still has very good coordination when it comes to sports. Does not seem to fit into any category or diagnosis.
