I think my son's disability, motor dyspraxia and hypotonia, would cause a big discrepancy between his verbal scores and performance scores, so he would have a lower FSIQ than his highly gifted half brother even though they seem so much alike intellectually. It always seemed to me that if a child has a disability and is able to learn and comprehend at very high levels in spite of the disability he should be considered to have a higher IQ, certainly not less, than the child who was able to learn and achieve at the same high level but didn't have to deal with the disability. I don't think my son's motor learning disability affects his intellectual ability in any negative way. I think he understands things that a lot of adults don't because of his disability, yet his FSIQ would probably be less than that of a child with a similar mental age and intellectual ability because of his disability.
I try not to think too much about all of this. I am trying to keep my blood pressure down and focus on things that really matter and focus on the positive. My son is homeschooling and is able to learn more on his own than he would in our public school so we don't have to worry about it.
