NVLD - bad, misleading, inadequate name

Post Reply New Topic

I consider communication disorders and Autism Spectrum Disorder to be Developmental Communication Angosia.

I call it Developmental Communication Angosia Spectrum Disorder.

Inadequate problem.

Why not just name Aspergers and autism the same thing?

Kind of.

Autism and Aspergers are now the same diagnosis: Autism Spectrum Disorder. This is true for both the DSM 5 which is primarily used in the United States and the ICD 11 which is used in the rest of the world. (Note that the ICD 11, though published, does not take effect until January 2022. The current version in use is the ICD 10 which does separate Autism and Aspergers, but this will change next January.)

PDD include Asperger's Syndrome, Childhood Disintegrative Disorder, and Rett's Syndrome. Children with PDD vary widely in abilities, intelligence, and behaviors according to National Institute of Neurological Disorders and Stroke.

Other forms of PDDs includes, PDD-NOS and Autistic Disorder as well.

All Pervasive Developmental Disorders are treated as Autism Spectrum Disorder with severity and with or without Intellectual Disabilities.

I am the original poster here and I "refresh" this topic.

I think that NVLD is a real thing, but I also think that many people with NVLD (also among those who were diagnosed with NVLD without co-morbid PDD/ASD) in fact have a pervasive developmental disorder or an autism spectrum disorder.

Autism is developmental social-emotional-behavioral disorder, NVLD is a neurodevelopmental learning disability. I suppose that many people with autism have co-morbid NVLD and maybe even more people with NVLD have co-morbid autism.

I would say that there are two main kinds of NVLD:

- hyperverbalia (term analogous to hyperlexia; relative dysharmony and imbalance in cognitive skills and profile; early or at least normal speech development, verbal skills and VIQ, VCI significantly higher than visual-spatial and visualizational skills and than PIQ, POI),
- developmental visual-spatial disorder (DVSD, qualitative impairment, not relative imbalance or relative dysharmony associated with visual-spatial abilities; impairment in reading nonverbal informations, especially spatial or visual, impaired reading of maps, graphs, clocks...).

A person can have hyperverbalia and may not meet criteria for DVSD or vice versa.

None, one or both: hyperverbalia and DVSD may be present in an autistic person.

I also would say that there are three main types of ASD/PDD-NVLD relationship:

1. ASD/PDD with NVLD (nonverbal communication imairment, social ineptitude and problems with interpersonal relationships, "quirkiness" and "peculiarity", one-sided interactions, content-flooding, "expansive mood" or social disinterest (sometimes being "aplatonic-like"), special interests or hyperfixations, hyperactivity or more typical self-stimulating behaviors, sensory discomfort intolerance or idiosyncratic sensory processing, punding or high-content thinking or peculiar customs, behaviors, rituals or routines - all or quite many of them are present since childhood and autisticity is present in adolescence and adulthood).
2. NVLD with non-clincal autism-like symptoms (social ineptitude due to visual-spatial impairment and difficulty reading nonverbal informations like visual messages).
3. NVLD without social ineptitude and without social awkwardness which does not look autistic.

Probably vast majority of NVLDers are in ASD/PDD with NVLD group or NVLD with nob-clinical autism-like symptoms group.

Subtypes.

"C. Subtype: Predominant Deficiency in Social Perception" is in my opinion a kind of autism/PDD which may not met DSM-V ASD criteria. "Rule-bound (when the rules change, they have difficulty accommodating; very literal; rigid" and "Difficulty with transitions; novelty" look to be a kind of meeting routines/rituals criterion of PDD/ASD which would give diagnosis of Asperger syndrome from ICD-10 even when restricted interests are not present. I am even not certain if people with this developmental disorder would meet social communication disorder criteria from DSM-V because SCD criteria require impairment of understanding of metaphors, hidden meanings (I am rather normal in deciphering metaphors and hidden meanings despite being diagnosed with Asperger syndrome when I was nearly 17 years old!).

I think that is easier to get support and help for PDD/ASD than for specific learning disabilities. Dyslexia and dyscalculia may be quite common and the term "pervasive developmental disorder" or the word "autism" appear to describe something severe which requires substantial support.

I think that there should be one subcategory of neurodevelopmental disorders associated with social ineptitude, atypical emotionality and odd behaviors and typical ASD would have to be not the only disorder in this category (such a category might be named "developmental social-emotional-behavioral disorders" or even considered "autism" in very broad sense of this word). I think that many people who should be considered as having autism are misdiagnosed as non-autistic and (or) not having a pervasive developmental disorder. Not every bright autistic person is like Temple Grandin!
