I think that someone with "mild NVLD" could be more in need of disability pension than someone with "high-functioning" ASD.
I would say that NVLD is a serious and complex developmental disability. Especially when there are traits of other disorders present in a person with NVLD.
ASD without NVLD impairs mostly "soft skills" while NVLD (even without meeting ASD criteria present in the DSM-V classification) impairs both "hard skills" and "soft skills". A person with ASD can be highly technical while NVLD impairs technical skills. People with NVLD have dysharmony between significantly better verbal skills (like memory for facts and spelling) and significantly worse visual-spatial skills (like visual imagination and precise visual memory). Someone with ASD can have balanced IQ profile or dominance of visual-spatial skills over verbal skills.
I would say that verbal skills are more useful academically than occupationally and performance skills are more useful occupationally than academically.
I would be interested in relationships between ASD, NVLD, ADHD and FGR (fetal growth restriction), LBW (low birth weight) and PTB (pre-term birth).
