Nonverbal learning disorder
It is described as something pretty similar to Asperger syndrome or ASD without intellectual development disorder and without serious functional language issues and I have "obsession" that I have merely nonverbal learning disorder, not pervasive developmental disorder and autism spectrum disorder. I would think that non-autistic nonverbal learning disorder is not similar to Asperger syndrome and it should not have social atypicality, but it would present with dyscalculia, dysgraphia and impairment in reading maps and charts in elementary school, so the person with NLD and without AS would be not "weird", but would have serious problems in learning because of problems with arithmetics, writing and reading of nonverbal information and there would be significant, early problems with mathemathics and with subjects in which maps are used, like geography and history. I would think that many people with autism have more or less NLD symptoms, but social-behavioral atypicality differentiates autistic people with NLD traits than people with NLD who do not have a pervasive developmental disorder.
