Do I have NLD?

https://www.sciencedirect.com/science/a ... 6714000889 - Comparison of the cognitive profiles and social adjustment between mathematically and scientifically talented students and students with Asperger's syndrome. Mathematically and scientifically talented students with average IQ (below 97th percentile) (MSTAIQ) and mathematically and scientifically talented students with high IQ (above 97th percentile) (MSTHIQ) have, on average, significantly higher scaled score in Block Design than in Picture Completion, Object Assembly and Picture Arrangement and no considerable weakness in Digit Symbol Coding, Symbol Search and Processing Speed Index, according to this Taiwanese study (which used WAIS-III). This description of mathematically and scientifically talented students fits to my WAIS-R results from 2016! Block Design 14, Coding 13, Picture Completion 9, Object Assembly 9, Picture Arrangement 8. So my "NVLD signature" from test done when I was 24 years old (VIQ 126, PIQ 104, POI 100, VCI 125, PSI 117(?), WMI 128(?)) appears to be a sign of mathematical-scientific orientation of my mind...

I saw a somewhat larger VIQs and lower PIQs in individuals diagnosed with PDD in Wechsler tests, such as in the situation when the author of this post (viewtopic.php?t=252601#p5925697) was 15 years old. Fragments NOTE: I took Block Design on the WISC-III, not WAIS-IV. When I was 8, it was my highest subscale score at 19 (and the only one on the performance IQ that was at 10 or higher). At 15, however, the subscale score dropped to 12 and was not my highest score (and again, it was the only one on the performance IQ that was at 10 or higher) and age 15, verbal IQ = 131, performance IQ = 93, total IQ = 113.

I read than in WISC-V Arithmetic is not a Working Memory Index subscale, but a Quantitative Reasoning Index (QRI) subscale and in WAIS-R test in 2016 extremely high Arithmetic (scaled score 18) lifted my WMI to possibly 128 (slightly better than Verbal Comprehension Index which was 125) despite having scaled score 11 in Digit Span and problems with backward Digit Span (Digit Span scaled score was my lowest VIQ subscale). There were no FRI subtests (Matrix Reasoning, Figure Weights) in WAIS-R. Figure Weights in WISC-V is both a FRI subscale and a QRI subscale.

I suppose that I can have a subtype of NVLD because I have problems with mental rotation tasks despite scoring 14 on Block Design in WAIS-R. My Coding scaled score was also not bad (13). But I performed poorly in Benton Visual Retention Test and very poorly in Wisconsin Card Sorting Test. My working memory may be significantly poorer than my Verbal Comprehension Index, I have quite poor memory for details, at least short-term memory. In WISC-V WMI subtests are Digit Span and Picture Span. I scored extremely high in Information in WAIS-R in 2016 (17) and Information is a VCI subtest.

I may have ASD, NVLD, ADHD and CDS (cognitive disengagement syndrome) traits, but I do not know how many of these disorders I have clinically... I have Asperger syndrome diagnosis from ICD-10, but there are no Asperger syndrome and pervasive developmental disorder in DSM-V and ICD-11.The terms "Asperger syndrome" and "pervasive developmental disorder" do not contains the word "autism". "I do not know if I am really neuroatypical, maybe I am just a NT with personality disorders and emotional problems"?

Despite scoring 14 in Block Design in WAIS-R, when I looked on mental rotation tests some moments ago, "all figures appeared the same for me where not all were the same"... I was "clueless" about how to choose correct answers in mental rotation tests. I do not see the difference and I have some sort of visual thinking "dyspraxia". In WAIS-R I scored 14 in Vocabulary, 13 in Similarities and 13 in Coding... So my results in Vocabulary and Similarities had the same scaled scores as my results in Block Design and Coding. But I "do not see the differences in mental rotation tests". Every options may look for me to be the same figures rotated somehow... "I can't spot the differences".

In WISC-V Arithmetic is not a Working Memory subtest, but Quantitative Reasoning Subtest (along with Figure Weights, which is also a Fluid Reasoning Index subtest). In WAIS-R I scored much better in Arithmetic than in Digit Span (I had marked problems with Digit Span backwards). Thanks to extremely high Arithmetic my WMI was a bit higher than my VCI (VCI was elevated by Information with scaled score 17). All VCI subscales were located "between" Arithmetic (18) and Digit Span (11). Block Design and Coding were also "between" Arithmetic and Information. Below Digit Span there was marked "POP valley" in PIQ consisting of one-digit scaled scores for Picture Completion (9), Object Assembly (9), Picture Arrangement (8). It looks quite impressively poor in comparison to scaled score in Block Design (14).

I think that I have "low phantasia", not aphantasia and not hypophantasia, because I can generate visual thoughts and my visual thoughts are somewhat sharp and vivid, not always merely dim and vague. But amount and usefulness of visual thinking may be considered not less important than its vividness and in my case, amount and usefulness of visual thinking is low because I have quite low amount of visual thoughts and I am "clueless" in mental rotation tests, do having not aphantasia and having not hypophantasia does not help me in these tasks which look difficult for me. I have not developmental topographical disorientation. Having Block Design with the same score as Vocabulary and even with minimally higher scaled score than Similarities does not look to be a NVLD trait.

I already noticed that I did not remember the sequence of color stripes of quite many country flags (Germany, Hungary, Slovakia, Lithuania, The Netherlands, India), although I would easily recognize them (maybe with the exception of Dutch flag, which has three colors similar to Russian flag and stripes on both flags are horizontal). I have poor precise visual memory for details. Just a moment ago I noticed that I confused positions of blue and red stripes on the Luxembourg flag. And I totally confused the sequence of colors on the Estonian flag.

I have hypophantasia-like condition (small amount of visual thinking, small precision of visual thinking although not necessarily dim or vague visual thinking (my visual thinking can be somewhat sharp and vivid, I think), fleetingness of visual thinking).
