psychiatry spectrum Autism has long been thought to cover a wide spectrum, ranging from individuals with severe impairments—who may be silent, developmentally disabled, and prone to frequent repetitive behavior such as hand flapping and rocking—to high functioning individuals who may have active but distinctly odd social approaches, narrowly focused interests, and verbose, pedantic communication. 1 Because the behavior spectrum is continuous, boundaries between diagnostic categories are necessarily somewhat arbitrary 2 classification why did "DSMV" compress "DSMIV autism subgroups"? (treatment) researchers found that these separate diagnoses were not consistently applied across different clinics and treatment centers 3 related : internal validity Diagnostic and Statistical Manual of Mental Disorders DSM5 vs. DSM4 developmental psychology ...it is an important change from DSMIV criteria, which was geared toward identifying school-aged children with autism-related disorders, but not as useful in diagnosing younger children 4 2. The restricting of onset age has also been loosened from 3 years of age to "early developmental period", with a note that symptoms may manifest later when social demands exceed capabilities. 5 insurance state intervention may be required to ensure that these individuals who may lose or fail to receive an ASD diagnosis will have continued access to public health support services; therefore, future research is needed to determine how states respond regarding insurance coverage and services for individuals without an ASD diagnosis but who still may require assistance 6 DSM5 vs. DSM4 psychiatric epidemiology the DSM5 criteria were tested in real-life clinical settings as part of DSM5 field trials, and analysis from that testing indicated that there will be no significant changes in the prevalence of the disorder 7 More recently, the largest and most up-to-date study, published by Huerta, et al, in the October 2012 issue of American Journal of Psychiatry, provided the most comprehensive assessment of the DSM5 criteria for ASD based on symptom extraction from previously collected data. The study found that DSM 5 criteria identified 91 percent of children with clinical DSMIV PDD diagnoses, suggesting that 2 DSM5 Autism Spectrum Disorder Fact Sheet most children with DSMIV PDD diagnoses will retain their diagnosis of ASD using the new criteria. Several other studies, using various methodologies, have been inconsistent in their findings. autism vs. social communication disorder the latter contains the former and a restricted pattern of behavior the diagnosis of SCD can only be given if autism has been ruled out. 8 did the generalization of autism in DSMV cause it to be less specific? why no e.g. some people are now getting the diagnosis of social communication disorder (instead of e.g. PDDNOS the specificity of classification increased, in this example 9 neuroscience neurophysiology dynamic functional connectivity dynamic functional connectivity → autism research into causes has been hampered by the inability to identify biologically meaningful subgroups within the autistic population 10 and by the traditional boundaries between the disciplines of psychiatry, psychology, neurology and pediatrics. 11 newer technologies such as fMRI and diffusion tensor imaging can help identify biologically relevant phenotypes (observable traits) that can be viewed on brain scans, to help further neurogenetic studies of autism; 12 one example is lowered activity in the fusiform face area of the brain, which is associated with impaired perception of people versus objects. 13 it has been proposed to classify autism using genetics as well as behavior. 14 → biological specificity neurodiversity it emerged as a challenge to prevailing views that certain neurodevelopmental disorders are inherently pathological and instead adopts the social model of disability, in which societal barriers are the main contributing factor that disables people 1516 The subsequent neurodiversity paradigm has been controversial among disability advocates, with opponents saying that its conceptualization doesn't reflect the realities of individuals who have high support needs. 171819 https://en.wikipedia.org/wiki/Autism#cite_note-113 ↩ https://en.wikipedia.org/wiki/Autism#cite_note-Geschwind-200952 ↩ https://web.archive.org/web/20131006210933/http://www.dsm5.org/Documents/Aut ism Spectrum Disorder Fact Sheet.pdf ↩ https://web.archive.org/web/20131006210933/http://www.dsm5.org/Documents/Aut ism Spectrum Disorder Fact Sheet.pdf ↩ https://en.wikipedia.org/wiki/Autism_spectrum#cite_note-IACC28 ↩ https://link.springer.com/article/10.1007%2Fs1080301420652 ↩ https://web.archive.org/web/20131006210933/http://www.dsm5.org/Documents/Aut ism Spectrum Disorder Fact Sheet.pdf ↩ https://en.wikipedia.org/wiki/Social_communication_disorder#cite_note-DSM56 ↩ https://www.autismspeaks.org/dsm-5-and-autism-frequently-asked-questions ↩ https://en.wikipedia.org/wiki/Autism#cite_note-109 ↩ https://en.wikipedia.org/wiki/Autism#cite_note-110 ↩ https://en.wikipedia.org/wiki/Autism#cite_note-111 ↩ https://en.wikipedia.org/wiki/Autism#cite_note-Lev200920 ↩ https://en.wikipedia.org/wiki/Autism#cite_note-112 ↩ https://en.wikipedia.org/wiki/Neurodiversity#cite_note-2 ↩ https://en.wikipedia.org/wiki/Neurodiversity#cite_note-Bloomsbury-3 ↩ https://en.wikipedia.org/wiki/Neurodiversity#cite_note-4 ↩ https://en.wikipedia.org/wiki/Neurodiversity#cite_note-5 ↩ https://en.wikipedia.org/wiki/Neurodiversity#cite_note-6 ↩
