My son has had comprehensive neuro-psychiatric testing done twice, once when he was 4, and again when he was 11. Both times he was diagnosed with NonVerbal Learning Disorder (NVLD), but Aspergers was never mentioned to me the first time, and the second time the psychologist ruled it out. However, from reading posts here on this board, it sounds like some docs are now saying it is one in the same? I would like to get your thoughts and feedback on this. What do you think the differences are between AS and NonVerbal Learning Disorder (NVLD)? What are the determining factors for AS after you have already gotten a NonVerbal Learning Disorder (NVLD) diagnosis? Is there a way to really know for sure either way? Thanks for your help in my enlightenment.
