AS and NVLD?

Post Reply New Topic

I found a very interesting article: http://www.nldontheweb.org/Dinklage_1.htm

It talks about the relationship between NVLD and AS. 80% of Aspies seem to have NVLD (non verbal learning disorder). The overlap between the symptoms of the two syndromes are very strong: impared socialization, motor coordination, difficulty in communication, strong ability in rote memorization, problems with gestault thinking, and so on. As far as diagnoses go, AS is considered more as a socialization problem, while NVLD is seen as more of an academic/cognitive problem.

A major difference between the two seems to be that those with NVLD tend to think verbally while aspies and autistics think more in pictures? Another major difference is that NVLDs do not lack a "theory of the mind" or suffer from "mindblindess" (whatever that means). Borh groups have IQs in the normal and superior range, though NVLDs tend to score really high on the verbal subscore but significantly lower on the performance subscore (they have the greatest problems in dealing with spatial relations). The diagnoses for the two are very similar, so it makes one wonder if there are people who are diagnosed with AS who are really just NVLD or vice versa. (Unlike AS, NVLD is not on the autistim spectrum. The cause seems to be brain damage to the right hemisphere when the person is really young (toddler/baby). AS probably has a much stronger genetic component.)

From what I've read, at least some experts feel that nonverbal learning disability, Asperger's syndrome, schizoid personality of childhood, developmental right-hemispheric disorder, and pragmatic-semantic language disorder are just different names for the same underlying condition, essentially. The different concepts emphasize different somewhat different criteria because they originate from different specialties and research backgrounds. For example, schizoid personality of childhood comes from personality type psychology.

I know, when I was very young, I thought in pictures instead of in words. The reverse is true now, though. Mental rotation and manipulation of complex imagery is difficult for me. I don't know if it's from post-natal brain trauma (there are many possible causes of that for me) or simple atrophy, but visualization is now a weakness for me. I still carry traces of visualization in my cognitive preferences, though. I am good with aesthetics and can tell if a word is misspelled by how it looks. I can create caricatures that aren't necessarily visually true to life but can sometimes be funny.

My verbal IQ is and has been much higher than my performance IQ for many years now.

The two sound so closely related, Im not sure that there is a marked difference.

As I understand it, NVLD implies reading difficulties

In that case then...

Question: would the rdos apie quizes distinguish between an aspie and a person who has NVLD? It has already been shown that the quiz does a good job of telling between aspie and NT nerdiness. I'm wondering how accurate it would be at telling the difference between Asperger's Syndrome and related disorders.
