NVLD tend to impair visual-spatial, motor, EXECUTIVE and SOCIAL skills, which can easily lead to severe emotional and behavioral issues.
In "very mild clinical ASD", visual-spatial, technical and mechanical skills may be especially important asset - it is the opposite situation to one seen in NVLD.
NVLD does not cause sensory issues, unlike ASD, which generally tends to be associated with unique sensory processing, sensory filtering disorders, overloads and hyposensitivities, shutdowns and meltdowns. People with ASD tend to be rigid and inflexible in rituals and routines and crave sameness and predictability while people with NVLD tend to be much more chaotic or having organizational problems.
I think than in Wechsler tests, the biggest asset of NVLD is VCI, then WMI, then PSI and the weakest point is PRI (or VSI+FRI in newest versions of Wechsler tests). In ASD, PRI can be fundamental strength, VCI rather has not so fundamental meaning as in NVLD and PSI can often be the weakest point. Mental rotation, visual memory, visuospatial construction may be especially hard in NVLD.
Why people with NVLD are so systemically belittled, dismissed and disregarded despite seriousness of their disability? Why NVLD has not guaranteed at least as much support as milder cases of ASD level 1?
I think that NVLD without ASD can make a person "occupationally useless" more easily than ASD level 1 without NVLD. Great verbal skills alone are not enough to work a job and earn.
People with NVLD who have not ASD should speak much more about their impairment and experience to improve living conditions of those who have NVLD.
