Nonverbal Learning Disorder
One thing which might be useful to keep in mind is that NLD is not a diagnostic category in the DSM-IV-TR. NLD developed within neuropsychology, not within psychiatry. (The DSM is a psychiatric publication.) Consequently, I would speculate that most people who, from a neuropsychological standpoint, would be treated as NLD would, from a psychiatric standpoint, be treated as either Asperger’s or PDD-NOS.
