We have an appointment with- our 3- year old's pediatrician on Friday, and we will be asking for a referal for a neuropsychologist evaluation. I am very anxious about this, and also very hopeful. husband and I will discuss our concerns about our little guy's development, and I also have a letter from his teacher to give him insight into what our son's school days are like. The letter is pretty good, I think it displays a lot of what we see at home. She put a lot of emphasis on the fact that he is a very high energy child, always running indoors and out, and very hyperactive. She also put things in there about him not being appropriate with- peers... knocking over their towers and projects, clearing toys of tables onto the floor. Towards the end she talked about how he usually responds well to deep pressure, joint compressions, as well as other sensory input. I wish I could just post the letter on here, but I'm not sure if that would be allowed? I would not put names, places, etc. in it. What husband and I observe with- our son, and his teacher's letter, do you think that will be sufficient for the doctor to give the referal? My fear is that he will just assume ADHD, and want to try stims. We do not want him on medication at this young of an age. I did the brainchild test, (I think that's what it's called), through a link posted on here, and result was mild Pervasive Developmental Disorder (PDD)-not otherwise specified. My instincts tell me that this is probably pretty accurate, he displays some signs of autism. Are there any suggestions for anything else I could bring to the doctor that would be helpful?
