The amygdala, cerebellum, and many other brain regions have been implicated in autism. [15]Unlike some brain disorders which have clear molecular hallmarks that can be observed in every affected individual, such as Alzheimer's disease or Parkinson's disease, autism does not have a unifying mechanism at the molecular, cellular, or systems level.
Among these measurements, the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) are considered the "gold standards" for assessing autistic children. [ 24 ] [ 25 ] The ADI-R is a semi-structured parent interview that probes for symptoms of autism by evaluating a child's current behavior and ...
A meta-analysis demonstrated that polymorphism of the MTHFR C677T genotype is correlated with an ASD diagnosis in children from countries lacking food fortification. [ 39 ] While MTHFR is a proposed genetic factor for ASD, there is limited clinical evidence from testing for MTHFR gene polymorphisms in the diagnostic setting. [ 40 ]
TreeHouse – a United Kingdom charity working to improve the quality of life of children diagnosed with autism and their families, and to inform the general public about autism spectrum disorders. Wrong Planet – an online community designed for people with autism, people with ADHD, PDDs, and other neurodivergent traits.
Unusual responses to sensory stimuli are more common and prominent in individuals with autism, and sensory abnormalities are commonly recognized as diagnostic criteria in autism spectrum disorder (ASD), as reported in the DSM-5; although there is no good evidence that sensory symptoms differentiate autism from other developmental disorders.

Additionally, children living in higher resources settings in the United States tend to experience earlier ASD interventions than children in lower resource settings (e.g. rural areas). [29] A difficulty for academic performance in students with autism is the tendency to generalize learning. [30]
It's a common refrain when adults (and children) receive their autism diagnosis. "Society does a very good job of making you feel 'crazy' or useless if you don’t function or behave in a way that ...
[37] [38] The WHO estimates about 1 in 100 children had autism between 2012 and 2021, as that was the average estimate in studies during that period, with a trend of increasing prevalence over time. [b] [9] [10] This increasing prevalence has contributed to the myth perpetuated by anti-vaccine activists that autism is caused by vaccines. [39]
