Non Verbal Learning Disorder

Post Reply New Topic

I am not certain if I have NVLD. My lowest performance IQ result was about 23th percentile and it was Picture Arrangement. Even my worst result was above 15th percentile. If I will hav in all PIQ subtest the same result as in Picture Arrangement, my PIQ would be 89.

In addition, the gap between VIQ and PIQ was not so profoundly large - only 22 points and it would be only about 10 when Arithmetic would be in PIQ section, not VIQ. I read that about 3,1% of population have VIQ higher at least 22 points than PIQ. Does it mean that everybody with at least 22 points higher VIQ than PIQ have NVLD?

My Arithmetic result (141 if I would have all VIQ subtest result at the same level) is about 99,68th percentile (https://www.iqcomparisonsite.com/iqtable.aspx). My VIQ (126) is about 95,8th percentile and FSIQ about 87th percentile. My PIQ is about 60th percentile. Difference between VIQ and PIQ is about 35 percentiles.

I scored better in Coding (13) than in Digit Span (11), although Coding is in performance section and DS in verbal section of IQ test.

I scored much better in Information than in Object Assembly (and Picture Completion), which looks very "eneldic". The difference is about 2,67 SD. How common is the situation in which at least one of above: Information, Vocabulary or Similarities is at least 8 "large" points higher than at least one of the above: Block Design, Coding or Object Assembly?

I found interesting fragment on https://climbingthecindercone.com/ (emphasis mine):

So it might be possible that one on five persons have NVLD? What should be the criteria for NVLD? Estimates vary very greatly - from 0,1% to 20%. I suppose that NVLD-like IQ profile (VIQ significantly higher than PIQ) might be relatively common (about 8-9% of population may have VIQ at least 15 points higher than PIQ). Does VIQ 22 points higher than PIQ means NVLD? I did not think about looking at eyes when I was a child, to about 16th year of life.

I estimate that aucorigia (developmental condition characterised by social inadequacy and peculiarity) occurs at about 3-5% of general population. The name is from "autocontrast" and "originality". Main types of aucorigia are NVLD, ASD and schizoaucorigia.

Another concept which can be associated with NVLD is dyssemia - impairment of nonverbal communication. I might read that it occurs in about 10% of population.

I can relate to these symptoms and scored 110 in verbal IQ and 82 in performance IQ. Always made excellent grades in college with needing tutoring in math in high school and tutoring in chemistry in college. Really seems like I have poor visual spatial and never understood why I felt so socially awkward. Now it makes sense, don’t read nonverbal cues and facial expressions well.

Are you diagnosed with NVLD or ASD or pervasive developmental disorder, like Asperger's syndrome?
I had revalidational hours (some sort of extra lessons) from mathematics and physics when I was about 17 years old.
I score 100% in mathematics and chemistry (both on basic level) in secondary school-leaving examination (SSLE).
I scored 97% on advanced SSLE in geography and 92% on advanced SSLE in mathematics. I had generally very good grades in geography and chemistry in school.

What were your results in subscales? For example in Vocabulary, Similarities, Information, Digit Span, Arithmetic, Comprehension (VIQ) and in Block Design, Object Assembly, Coding, Picture Completion, Picture Arrangement (PIQ)?

https://www.researchgate.net/figure/Mea ... _243968890 - here a group of individuals with AS has average PIQ 101.8, average VIQ 105.9 (4.1 points higher than PIQ). NVLD group has VIQ 113.1 and PIQ 96.3 (only 16.8 points lower). I had PIQ 22 points lower than VIQ and have AS diagnosis.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756758/ - long article with the table in which one of subgroups of mentally healthy individuals has average VIQ 15 points higher than average PIQ. So VIQ at least 15 points higher than PIQ not always means a mental disorder?

Here (http://www.icd-code.de/icd/code/F74.-.html) I found a page in German which says that there is such a condition as "Dissoziierte Intelligenz" characterised by at least 15 points split between VIQ and PIQ or vice versa. Such a disorder is classified here as F74.

https://nvld.org/faqs/ - I found such a fragment, text (with my emphasis):

I was not so interested in having friends, being loved so much, although I wanted to have the female partner when I was about 7-9 years old. Maybe it was just evil lust or a need of romantic relationship? Now I am without friends and colleagues and I am not so sad because of it (and I do not have depression).

I think that NVLD can be more disabling than ASD lvl 1 or mild ID in some cases.
NVLD is not like dyslexia, it is more like autism spectrum disorder and in my opinion it has to be counted as a pervasive developmental disorder, not a specific one. Most of NVLDers can be (by extension) named as "autistic" in my opinion. NVLD is something like "autism-type disorder", "autismotypal disorder", which is analogous to schizotypal disorder, schizoprenia-type disorder. The same with SCD.
I think that the definition of PDD has to be broaden to include NVLD, especially or at least NVLD with social ineptitude or peculiarity. SCD should also be in one subgroup of developmental disorders with ASD.

NVLD is interesting and does seem to fit the he PDD diagnosis very closely.

I strongly disagree with the opinion seen on that page: https://www.quora.com/What-do-you-think ... in-the-DSM (Question: What do you think about the way that all forms of NVLD have been grouped under ASD in the DSM?)

I think that preventing NVLD individuals to be in one category of developmental disorders with ASD is a disservice to NVLDers because it underestimates the severity of NVLD. I have rather NVLD than ASD and have no friends and colleagues (and may even not have so much need to have them), my nature appears to not crave for social acceptation and being loved. I am rather verbal thinker and have VIQ significantly higher than PIQ and think that in USA I would not be diagnosed with ASD/PDD.

Maybe not all, but many NVLD forms could be named "autism" in my opinion. So I would disagree (at least in some way) with the opinion that NVLD is NOT autism. For me "social communication disorder" from DSM-V is a sort of autism. For me everything which makes a child socially inadequate and peculiar is "autism". Schizoid childhood disorder is also "autism" for me.
