Don't take it from me, take it from the first link on a cursory google search: > Autism Spectrum Disorders (ASDs) are a heterogeneous group of neurodevelopmental disorders that are diagnosed solely on the basis of behaviour. A large body of work has reported neuroanatomical differences between individuals with ASD and neurotypical controls. Despite the huge clinical and genetic heterogeneity that typifies autism, some of these anatomical features appear to be either present in most cases or so dramatically altered in some that their presence is now reasonably well replicated in a number of studies. One such finding is the tendency towards overgrowth of the frontal cortex during the early postnatal period. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5192959/ My interest in this thread is exhausted, so I'll agree to disagree with you on the biological deterministic aspects of autism, and let you dig down that rabbit hole. My guess is that either you have no lived experience with autism, don't know many people in the autistic community, or have a lack of sensitivity to the very real nature of the disabilities it entails, even in the undiagnosed cohort—enthusiastic misdiagnoses aside. The difficulties from dyspraxia are of very real consequence, regardless of social interpretation. Stimming and regulating behaviours are a real thing, regardless of whether or not it is frowned upon in a social context. Meltdown, i.e., the consequences of not being able to regulate congruently to one's environmental stimulation and fatigue, is a real thing, whether it is accommodated for or not, in the same way that an epileptic fit is a real thing. One could say that a majority of the population is affected by this, and it doesn't change my argument. One could say that some people are so barely affected by their meltdowns, and it doesn't change my argument; they are still real adverse effects of real consequence experienced by people—actual disability—and no amount of equivocating makes them go away. There's perhaps people who are slightly hypochondriac and are looking to pathologize themselves, but this doesn't change my argument, because they aren't autistic, they're just making false claims. There's perhaps some practitioners who are either incompetent or corrupt, and this doesn't change my argument, because they are misdiagnosing. > ASD-only vs ADHD-only vs OCD-only Strictly my opinion: the kitchen-sinking of ADHD, OCD, ASD, dyspraxia, meltdowns etc. is due to the gaining traction on the idea that there's a neurological commonality that drives these behaviours, and their attendant comorbidity. Occam's razor. |
