He sounds very similar to my daughter. Emotions and the like. We started to notice trouble in Kindergarten (in 2nd grade now). She has diagnoses of ASD (high functioning and a provisional diagnosis), SPD, and ADHD. We had the school do a full evaluation on her in first grade after a lot of pushing to get them to do it. She now has an educational diagnosis of dyslexia along with anxiety and depression related to school. She also qualified for counseling and social skills classes. I believe that the anxiety can be a hallmark sign of dyslexia (along with many other issues) and since you have a family history I would request an eval from the school (in writing). You can do a full neuropsych, but they are costly and as others have said, the IQ part may not be as stable at this age, so you may want to save that as your backup if you can't get the school to comply. I would look up dyslexia laws in your state to request and eval from the school.
