Merger with Autism[edit]

As the terms Autism and Autism spectrum are increasingly used in reference to the same condition, I recommend a merger of both articles. ADeviloper (talk) 16:18, 8 February 2015 (UTC)

I looked in the archive and saw that this was briefly discussed back in 2011, here. It was also discussed briefly in the autism article back in 2008 here. ADeviloper has also currently proposed this at the Autism article here. I am going to propose that formally by tagging the articles. I will direct discussion to this thread.
My reasoning (and I may be wrong) is that ASD is the broad diagnosis in DSM V, and autism is one classification within that, and much of the content in autism is about the spectrum. It seems to me that much of the content from autism should be merged here, and this article should have WP:SUMMARY sections from each of autism, asperger's, and the other classifications, to knit the related articles together.
In any case, I don't see that this has ever been thoroughly discussed and it perhaps should be. I do acknowledge that Autism is a featured article and that editors like SandyGeorgia have worked heroically to keep it that way. Nonetheless, this seems ripe for discussion. Tagging now. Jytdog (talk) 17:05, 8 February 2015 (UTC)
  • Oppose. As clearly explained at the autism article, the Featured article refers to classic autism, not the full spectrum (which includes other conditions). Articles on both are necessary, they are separate concepts, the autism article is about classic autism, and in any case, a Featured article -- vetted by a community process -- is not going to be merged away via a merge request. SandyGeorgia (Talk) 22:44, 8 February 2015 (UTC)
hey sandy. i know you are very very close to the Autism article (and it has been a great accomplishment to get it there and even a greater one to keep it there). Can you see that there is a bunch of content in the autism article that is really about ASD? In my view, there is a bunch. Jytdog (talk) 23:43, 8 February 2015 (UTC)
If you give me samples of any text at autism that doesn't apply to classic autism, we can discuss moving it to autism spectrum, but we can't merge away a featured article, particularly when the two terms are notable and worthy of their own articles. PS, I think this discussion is on the wrong page. Autism is an FA-- a discussion of doing away with a featured article belongs on its page. SandyGeorgia (Talk) 00:40, 9 February 2015 (UTC)
sorry i am being unclear. i never meant to merge the whole thing - just the general parts. But that is only if folks agree that this article should be the top article in the suite. I think that is where the field is -- ASD is the top, and autism is one category within that. am i wrong? if you don't agree with that there is no point in continuing (I am sure you and others who regularly work here know the literature better than i) Jytdog (talk) 01:08, 9 February 2015 (UTC)
but to answer your question, when i read the Causes section, and the Mechanism section, of the autism article, i see nothing there specific to the autistic classification per se.... Jytdog (talk) 01:12, 9 February 2015 (UTC)
OK, so I'm still not clear on what you are proposing, or that you are understanding the consequences and process. I have no idea what you mean by "top article" ... ?? What has happened here is that this article is junk because no one cares, while autism is in good shape because it is watched because it is featured, comprehensive, and vetted. This article has been junked up (here is what it looked like when Eubulides-- who authored the entire autism suite-- last edited it.) Our article naming convention has nothing to do with a "top" article ... so I'm lost on what you mean by that ... We have two separate topics that meet notability, and one of them is in good shape, comprehensive, well written because it is featured, while the other is the usual Wikipedia garbage dump, deteriorated from when Eubulides maintained the entire suite. Perhaps we aren't following what each other is saying.

To merge away a Featured article means to defeature it. (There have been three such cases in the history of Featured articles.) Yes, autism is one kind of ASD; if you are saying that autism is a content fork from ASD, and that content is in the wrong article, then we have to go to FAR and propose delisting autism as a featured article. Then you move good content from a featured article into this crap article, and we end up with one large bad article. Just to be sure you understand the process ... by merging content to here, you don't end up with a featured article ... you lose a featured article, and then folks unwatch, and then we get even more deterioration.

I don't know the literature better than you, because you have better journal access than I do. The autism article was written about classic autism by Eubulides; in the older versions of this article, it was only about the spectrum (who knows what all garbage is in here now since Eubulides left). The article organization once worked; if you are saying it no longer does, then we lose the Featured article. One less article for me to watch over is OK with me :) :) But it was my understanding then that nothing in the autism article was not about classic autism.

However, I would recommend renaming the other article to Classic Autism as laymen may easily confuse the two - and it seems even professionals sometimes use 'autism' to reference the entire ASD.--Humorideas (talk) 19:49, 22 October 2015 (UTC)


Would it be worth mentioning on this article (and the Autism one) that "classic autism" is also sometimes referred to as Kanner's Autism to differentiate it from other forms of autism? Iridi (talk) 22:39, 10 March 2015 (UTC)

ABA therapy NPOV[edit]

Saying that ABA is universally considered effective is at the very least an NPOV issue. Many prominent autistic rights' organizations and autistic bloggers have made public statements condemning the practices as abusive and denying their effectiveness as therapies. (talk) 00:25, 7 May 2015 (UTC)

The effectiveness of therapies would fall under WP:MEDRS which none of those do. Dbrodbeck (talk) 01:08, 7 May 2015 (UTC)

What I intend to do with the article, and what new information will I add? Subtitle: Serotonin regulation I intend to add the link between low serotonin levels in the brain and the development of autism spectrum. Serotonergic system malfunction is one of the most associated causes of autism [1]. Vitamin D binds to the Vitamin D receptor which heterodimerizes to the retanoid receptor, creating the Vitamin D response (VDR) which regulates many genes including ones coding for Tryptophan hydroxylase 1 and 2 (TPH1 and TPH2) [2], which are the rate limiting enzymes responsible for converting Tryptophan into seratonin in the gut and the brain, respectively. [3]. The vitamin D response element binds sequences in the DNA that either indicate to the complex to recruit co activators thereby turning on genes or core repressors which results in turning off genes [4]. The vitamin D response turns off the enzyme TPH1 which regulates production of serotonin in the gut, and turns on TPH2 which converts tryptophan into Serotonin in the brain [5]. Without this regulation, higher than optimal levels serotonin may be produced in the gut, and lower than optimal levels may be produced in the brain. IDO, another enzyme produced in the placenta converts Tryptophan into Kynurenine which is converted to T regulatory cells. Both IDO and tryptophan are expressed in the placenta [6]. T regulatory cells are known to prevent immune cells from attacking host tissue [7]. Female mice have strong immune resonse against fetus if IDO does not exist [8]. Tryptophan is known to have a greater binding affinity to TPH1 compared to IDO, therefore low Vitamin D levels result in TPH1 being produced, and binding to tryptophan and IDO having a suppression of activity [9]. It is known that Mothers of Autism spectrum children have a greater chance of having antibodies against fetal brain proteins in their blood compared with mothers of nonautistic children [10]. Moreover, autoantibodies target the fetal brain during pregnancy [11]. Therefore, maternal blood levels of vit d are imporant for the delivery through placenta and serotonin production in the developing fetus. 2-3 sentences on your topic that will be in the final article Jump up ^ Zafeiriou, D.

autism spectrum and violence[edit]

I've heard that most studies don't support a correlation between autism and violent crimes (or was it just AS?) but on the other hand ASD is also associated with tantrums, violent outbursts and reactive aggression, and I noticed it seems a disproportionate number of recent mass shootings in the US have been committed by people diagnosed with ASD/AS. Then I found this study: Haven't read through it but seems like it might have some valid points. Any thoughts?--Humorideas (talk) 19:55, 22 October 2015 (UTC)

WikiProject Medicine - Proposed Edits[edit]

Hi all, I'm part of the WikiProject Medicine course at UCSF and have identified a few areas I'd like to work on for this page. Outline is below - looking forward to hearing everyone's input!

General changes: 1-2 more photos; Inserting references where flagged and/or deleting statements for which references cannot be found; Simplifying language (per Acrolinx report); Consistency between person-first and identity-first language (ideally would like to change all to identity-first)

Lead section: Less medical jargon while still maintaining a neutral point of view

Classification: Clarification of DSM-5 vs. DSM-4 and language no longer being a criteria (still mentioned in differentiation between autism and Asperger syndrome)

Characteristics: Will potentially remove and or streamline "Developmental Course" to take out specific prognosticating language

Associated conditions: Will be merged with "comorbid conditions"

Management: Will incorporate discussion from Talk page re: ABA therapy

Peer Review[edit]

Great, thorough article that is well organized. Overall, no obvious problems jumped out, except perhaps the complicated sentences and expressions, making the information more challenging to understand to the lay person. In this regard, I know you have made substantial improvements to the original content. I liked the links under many headings to other main articles.

Some notes, section by section:

Intro: Succinct, but some information is repeated in the Classification section. I would copy this detailed information into the Classification section, and instead write something simpler here: Autism spectrum or autistic spectrum describes a range of conditions classified as neurodevelopmental disorders in the fifth revision of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5), encompassing diagnoses of autism, Asperger syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS), Rett's disorder, and childhood disintegrative disorder.

Classification: Very thorough. Some sentences could use simplifying/shortening. This is the most confusing, IMO: Rather than categorizing these diagnoses, the DSM-5 has adopted a dimensional approach to diagnosing disorders that fall underneath the autism spectrum umbrella. Some have proposed that individuals on the autism spectrum may be better represented as a single diagnostic category, because they demonstrate similar types of symptoms and are better differentiated by clinical specifiers (i.e., dimensions of severity) and associated features (i.e., known genetic disorders, and intellectual disability). Here, "in turn" could be taken out (not needed): ASD, in turn, is a subset of the broader autism phenotype (BAP), which describes individuals who may not have ASD but do have autistic-like traits, such as avoiding eye contact.

Characteristics: This is an excellent section that is very easy to read.

Developmental Course: "Although autism spectrum disorders are thought to follow two possible developmental courses, most parents report that symptom onset occurred within the first year of life." - try to rewrite, maybe not start the sentence with "although". Try this?: Most parents report that symptom onset occurred within the first year of life. Autism spectrum disorders are thought to follow two possible developmental courses.... etc.

Causes: "While a specific cause or specific causes of autism spectrum disorders has yet to be found, many risk factors have been identified in the research literature that may contribute to the development of an ASD." - Just simplify to "a specific cause", don't think you need single vs plural

Genetic risk factors: "Instead, there seem to be multiple genes involved, each of which is a risk factor for part of the autism syndrome through various groups" - sentence unclear. What various groups? Maybe link to terms like "prevalence" vs "incidence", etc.

Prenatal and perinatal risk factors: Great.

Vaccine controversy: Great, slightly wordy.

Pathophysiology: minor change: "enlargement in some areas and brain reduction in others". This would make little sense to a non-medical person: "In neuroanatomical studies, when performing Theory of Mind and facial emotion response tasks, the median person on the autism spectrum exhibits less activation in the primary and secondary somato-sensory cortices than does the median member of a properly sampled control population. This discrepancy is consistent with reports of abnormal patterns of cortical thickness and grey matter volume in those regions of autistic persons' brains."

Mirror Neuron System: Maybe there are pages that could be linked to define the brain areas?

Temporal Lobe: Great.

Mitochondrial Dysfunction: Great.

Vitamin D: Great.

Diagnosis: Evidence-Based Assessment: Great as is - a comprehensive list of diagnostic tools

Comorbidity: Great.

Management: I don't know if there is a rule about using "likelier" vs "more likely", but I think more likely sounds better. I would rearrange the first sentence, so the sentence does not start with "although". "It has been argued that no single treatment is best and treatment is typically tailored to the child's needs." - this sentence is repeated twice in the paragraph, with minor variation. Remove one. Maybe change this sentence to: "OTHER Available approaches include: developmental models, structured teaching, speech and language therapy, social skills therapy, and occupational therapy." - just so ABA is not repeated again. Maybe change this to: "Applied behavioral analysis is one of the most empirically supported intervention approaches... etc", just so it does not sound like you are introducing ABA for the first time.

Epidemiology: Link to "prevalence"

History: This sounds more like "Causes", and could maybe be moved there? Or maybe preface these two interesting bits with some kind of summary statement, about why this is included.

Society and Culture: "Families who care for an autistic child face added stress from a number of different causes. One study found that half of parents who had a child with any kind of developmental disability were still caring for their child by age 50, while only 17% of parents that age would typically be caring for children." This sentence is very out of place. The information flows much better without it. However, this is a powerful statement, so just try to move it elsewhere. (talk) 03:42, 18 November 2015 (UTC)

Thanks so much for your review! You picked up on a lot of areas for clarification of language that I never would have noticed. Just to summarize my response to each section and what I changed/left:

Intro: Left as is. I agree that merging the two intro sentences might be more concise, but think that might be a little less readable than two shorter sentences.

Classification: Removed "in turn," and attempted to clarify the "dimensional approach" sentences. Thanks!

Developmental Course: Switched order of phrases in first sentence.

Causes: Chose to go with "causes" rather than "cause," but agree that only one was needed!

Genetic risk factors: Attempted to clarify last sentence, and added lots of links. Thanks!

Vaccine controversy: Found one awkward/unclear phrasing ("supported by multiple lines of evidence..." and changed to "and further evidence continues to refute them")

Pathophysiology: Linked to lots of neurology jargon terms - as paraphrasing would make the reporting of the findings less accurate.

Mirror Neuron System: Linked!

Management: Oops - definitely didn't see that "likelier" before. I agree! I see many others have been editing this section as well since I last worked on it, so I tried to remove repetition/consolidate between them while preserving all of the ideas/evidence shared. I also broke up into shorter paragraphs.

Epidemiology: "Prevalence" linked!

History: I toyed around with the idea of moving this into a subheading of "Other causes proposed in history" in the Causes section, but thought this would cause more controversy/confusion and would make people more likely to think that these are still currently thought to be causes. So I left as is.

Society and Culture: Good catch! I agree it is a necessary point but breaks the flow of the paragraphs about ARM. Split up the section into "Autism Rights Movement" and "Impact on Caregivers."

edits re rural and interactive TV[edit]

The following was added today in this series of diffs.

moving it here for discussion and review. headers have been changed to bold to keep this in one section.

Interactive Television

Children with ASD who live in rural and poorer areas are diagnosed at a later age compared to those in urban or suburban areas.[1] The interagency Autism Coordinating Committee (IACC) is currently trying to focus on accessing services, reducing inequities, and promoting earlier detection and intervention for individuals in rural and underserved areas.[2]

In order to improve outcomes for children with ASD, families should be afforded equal opportunities to access high quality health care. Earlier detection and intervention should be promoted for the families in rural and underserved areas. One possible solution is using the video conferencing (VC) to aid in assessment and diagnostic procedures.[3] It is an easier means to reach families in rural and underserved areas. The study shows excellent inter-rater agreement on diagnoses between clinicians in the VC setting and the interdisciplinary team. It suggests that VC may be a viable method to increase access to autism diagnostic services and possibly early intervention for families in rural and underserved areas.[4]

Reese created the Integrated Systems Using Telemedicine (ISUT) Model, which links families, trained early intervention providers and educators, and university-based medical professionals. One non-randomized study reported that the ISUT Model was both well-received and cost-effective for families in rural areas requiring access to ASD diagnostic services.[5]

There was a study comparing the clinical utility and validity between interactive VC and an in-person assessment that uses standardized ASD diagnostic tools (e.g., the Autism Diagnostic Observation Schedule-Module 1, the Autism Diagnostic Interview-Revised). The results suggested that there were no significant differences in either the diagnostic accuracy or reliability when assessment obtained in-person or remotely. Even more, parents reported equally satisfied with both of the observational conditions.[6]

content added today[edit]

content below was added in this dif, which also deleted the infobox. refs need to be fixed (pmid added), formatting, and copyediting, before this goes live

Role of Copy Number Variable Genes

Around 5-10% of autism spectrum disorders (ASDs) are observed to be the results of rare (<1%frequency) De nova or inherited copy number variations (CNVs). Genes involved with CNVs tend to be synapse-related genes that to have copy-number dosage-dependent effects on either the behavior or cognition of affected individuals[1]. Some studies have found the number of De novo CNVs to be fivefold higher in families with an individual with an ASD when compared to those who do not[2]

. Recent studies have identified hundreds of possible CNV regions related to ASDs. Data supports an association between rare De novo events at specific loci and the risk of ASDs. ASD has a highly heterogenic genetic background, and the majority of either common or rare CNVs do not necessarily lead to ASDs, but may increase the risk of developing one[3]. Most likely, the clinical presentation of ASD is the result of multiple variants acting in concert.

While scientists have identified hundreds of candidate CNVs associated with ASD, CNVs with the strongest evidence associating them to ASD, have been identified, isolated and studied more vigorously[2]. Research focuses on many De novo events, the most common of which occur at three separate loci, 7q11.23, 15q11.2-13.1, and 16p11.2.

Mutations to the 16p11.2 region of chromosome 16 are associated with hyperactivity in clinical ASD. Given that the mutation is found at a relatively high frequency, 1%, in ASD cohorts and rarely found in the siblings of ASD individuals, there is strong evidence supporting the large effect of duplications and deletions to this locus[1]. This locus is also related to schizophrenia, bipolar disorder and obsessive-compulsive disorder (OCD).

The 7q11.33 locus, found on the long arm of chromosome seven, is associated with Williams-Beuren syndrome, which is characterized by a reciprocal deletion in this region and related to highly social personalities[3]. The most common occurring De novo mutation to this region of the chromosome presented in ASD seems to have a very different effect than that of Williams syndrome. As opposed to deletions, the mutation involves four recurrent De novo duplications and presents as increased behavioral problems.

The de novo CNV occurring at 15q11.2-13., on chromosome 15, is the most commonly cited cytogenetic abnormality identified in idiopathic ASD. Duplications in this region are not only associated with ASD, but also with general intelligence disorders (IDs), while deletions to this region are strongly associated with schizophrenia and epilepsy. CNVs in this region, alone, have only moderate or mild effects, and it is most likely that some other genetic factors are required for this phenotype to reach ASD threshold[1].

Ok, I will suggest this again once the ICD 11 is out of beta. I did not know it had to be in WHO's current criteria, last updated in the 90s. The other main one, the DSM V, was updated more recently, 2013, and has merged, which is why I suggested it. [1] I am sorry for my mistake, I will wait until 2018 next time. —

Where did I say it was? I am not even American, and my country uses ICD 10 as a result of that. My point is that the more recently updated manual, the DSM V, has merged (2013 knowledge vs 1992 knowledge), and that the ICD 11 is going to follow that merge (which you can view by going to their beta page). If this is a problem, that is ok, I will post this suggestion again in 2018 once they follow that merge. —
