Anybody with enough will and persistence can find support for almost any viewpoint they desire concerning autism, depending especially on (lower) quality of source material. However, if you read enough, consistent patterns will emerge in the literature. This issue of Dialogues in Clinical Neuroscience is all about autism. Although all of it is valuable, I ...

The Flynn effect refers to the tendency over the last century or so for IQ scores to increase each generation by a few points. There is no link between vaccination and autism. It is pseudo-scientific myth, which has dangerous consequences for public health. see discussion here. I'm no expert in autism research, but in general, children with autism have ...

In light of a recent question in MedicalSciences.SE, I thought I would update this answer to include some information from my answer there. Autism spectrum disorder (ASD) now affects one in 68 births in the United States and is the fastest growing neurodevelopmental disability worldwide (Edmiston, et al. 2017) [free access paper with links to cited papers]. ...

It is important to remember when reading this question and answer is that Autism Spectrum Disorder (ASD) does not develop in adulthood, but symptoms can change for individuals over time because learning occurs. Symptoms of ASD come in all shapes and forms because this is a spectrum disorder and therefore people present somewhere on a spectrum, often ...

Difficulties with language is not actually a symptom of autism. Autism Spectrum Disorder involves difficulties in social communication and interaction, as well as restricted and repetitive interests or behaviours (DSM-V, 2013). The term "social communication" is referring to difficulties in the social aspects of language and other communication, such as ...

I don't know what the author(s) or editors intended this to mean exactly, but I would guess that examples could include smiling, shrugging, head-scratching, pointing, holding out one's hand to invite a handshake, management of personal space, etc. I'd love to know if I'm incorrect on any of these, but I'm a little pessimistic about finding out TBH. There may ...

Asperger's being "subsumed" in DSM-5 is not the whole story. There's indeed a new DSM-5 coding for the severity of the disorder. But applying the DSM-5 actual clinical criteria results in fewer people being diagnosed with autistic spectrum disorders, and the reduction is more significant for the mild versions (such as Asperger's): A 2014 mini-review looking ...

Symptoms of Asperger’s Syndrome difficulty recognizing social cues awkward body language social isolation aloofness fixation on certain objects The picture (and idea) that “stacking cans” is in itself a sign of Asperger’s is misleading at best. One could just as easily say this child is making “a tower”, a common activity amongst children. Asperger at ...

You don't say what language you want the tests to be in, so I'm assuming English. In the book Evidence-Based Assessment in ASD (Autism Spectrum Disorder), author Kenneth J. Aitken "describes and analyses a wide range of available Autism Spectrum Disorder (ASD) assessment measures". The chapter on "Attention" lists the following tests: Conners' Continuous ...

Why might sleeping on the floor alleviate PTSD symptoms? Question: Does sleeping on the floor have similar neurotransmitter effects, as sleeping under a weighted blanket might? Psychiatrically, would it be expected that a person having PTSD would find similar results sleeping under a weighted blanket as they do when they sleep on the floor? There is also a ...

The evidence in support of binaural beats as a therapeutic tool is sketchy: Is there scientific evidence on the benefits of binaural beats? Given our lack of understanding of if binaural beats can cause entrainment in the brain, never mind how they cause entrainment, it is not possibly to make conclusions about how the binaural beat would affect the autistic ...

Clark et al, 2008 show impairment in ASD individuals for detection of the emotional content of microexpressions. In general, ASD individuals have trouble discriminating the nuance of facial expressions (though some argue otherwise: see for example Ozonoff et al 1990), for example the differences between genuine smiles and posed smiles (for example, Boraston ...

They may be referring to hyperlexia (rather than hyperverbal ability): Hyperlexic children are characterized by word-reading ability well above what would be expected given their age. ... Some experts believe that most children with hyperlexia, or perhaps even all of them, lie on the autism spectrum. But as far as verbal ability goes, since autism is a ...

As an Autistic person myself, and as a person knowing many autistic people, I can assure you we indeed are capable of language. Even very low functioning autistic individuals are at least somewhat capable of speech, this is not true in all cases, of course; but it is not, in the majority of cases, to the degree of them being incapable of language ...

"The more you do something (whether you particularly "enjoy" it or not) the more likely you are to build it up as a habit" This simply is not the case. "So in this regard, it can be addictive behavior in the same way a "bad habit" can." Bad habits can not be "addictive". That is not what either word means. ...

What is Autism? Psychologists, psychoanalysts and neuroscientists all commonly apply a triune model of the brain : The Reptilian complex (aka “instinct” aka “the Id”) : where primitive subconscious emotions (such as sadness, anger, fear and happiness) reside and which is correlated to primitive neurochemical algorithms that measure one’s capacity to take ...

Robot-assisted therapy doesn't automatically mean that it is separate kind of therapy. You may for example teach an imitation by ABA principles with the robot. In other words, you are following traditional therapies but also using a robot. Kids may benefit from robot-assisted therapy primarily because robots are usually reinforcement for them, i.e. kids ...

There are many issues packed into this question. I am pretty sure the answers will lead to many more questions. People diagnosed with autism tend to perform worse than the average population on standard IQ tests, but there is evidence that alternative measures of "intelligence" (whatever that is) are more accurate and demonstrate that autistic persons, as a ...

No. I can't seem to find a specific study into professional mathematicians or graduate students so far, the studies always seem to group the occupations together. However, Baron-Cohen's team has done an impressive national survey (Ruzich et al., 2015) and recruited nearly half a million people through a UK TV show. They managed to get over 450,394 survey ...

There was a study which examines the exact question you posed. This study, which was conducted by Stone et al. (1999) compared accuracy of diagnosis of autism and a pervasive developmental disorder not otherwise specified (PDD-NOS). With regard to autism, the study suggested 2 conclusions: (1) the identification of an autism spectrum disorder can be made ...

It is difficult to identify autism definitively in other species, especially since autism encompasses a very diverse group of people who have different experiences. However, because there is so much interest in studying autism, researchers have developed models for autism in model organisms, specifically in mice, which share some of the diagnostic features ...

The source of the image (which also appears here, here, and here) is the Walter Schneider lab at the University of Pittsburgh. They have a webpage about an episode of 60 Minutes that featured their research (including high density fiber tracking of Temple Grandin's brain) related to Grandin's book, The Autistic Brain. The images can be found under FAQ #5 ("...

High-functioning autism along with Asperger's syndrome were both subsumed by Autism Spectrum Disorder in the DSM-5 in 2013. The Autism Society has a good page on the distinctions and history of these various diagnoses.

What you propose Is it possible that someone has level-3 (severe) autism yet on superficial look or talk the disability does not appear? is nonsense by the usual (DSM) definition of autism, which is based on several criteria which are behaviorally defined, i.e. from an observer's standpoint, to start with a child must have persistent deficits in each of ...

No. The key term that will help you look for research about this is the word "biomarker". There are certainly correlations with autism and some of the measurement techniques, but they aren't specific enough to be used for diagnosis. Plitt et al 2015 compared fMRI classification to a behavioral scale in high-functioning ASD vs IQ-matched typically ...

Yes, this may happen with Asperger subtype of autism. AS had already been described in 1981 by Lorna Wing, who first proposed the term to refer to a special subgroup of children who, according to Asperger’s original description, were characterized by: social isolation and lack of reciprocity in social interactions; normal or precocious language acquisition, ...

It can range from savant-like skills to extreme dyscalculia, some are very mean or average. The savant stereotype is caused mostly by many Western films which is applicable only for a small fraction of ASD population; for the others in ASD spectrum it is misleading and unhelpful.

There is some evidence that pet therapy are effective for individuals with autism. The studies did not differentiate between children and adult though it is likely that the studies are focused on children. This 2012 systematic review by O'Haire found increased social interaction and communication as well as a decrease in problem behaviors, autistic ...
