In the UK the National Autism Plan for Children recommends at most 30 weeks from first concern to completed diagnosis and assessment, though few cases are handled that quickly in practice. [6] Lack of access to appropriate medical care, broadening diagnostic criteria and increased awareness surrounding ASD in recent years has resulted in an ...
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder characterized by repetitive, restricted, and inflexible patterns of behavior, interests, and activities; deficits in social communication and social interaction; and the presence of high or low sensory sensitivity.
Research-determined cut-offs identify the potential diagnosis of autism spectrum disorder, allowing a standardized assessment of autistic symptoms. The Autism Diagnostic Interview-Revised (ADI-R), a companion instrument, is a structured interview conducted with the parents of the referred individual to cover the subject's full developmental ...
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.

Refrigerator mother – an accusing label for mothers of children diagnosed with autism or schizophrenia, now widely understood to be a myth. Thiomersal and vaccines – describing discredited claims that vaccines containing the mercury-based preservative thiomersal contribute to the development of autism and other brain development disorders.

Rett syndrome brain samples and autism brain samples show immaturity of dendrite spines and reduction of cell-body size due to errors in coupled regulation between MECP2 and EGR2. [62] However, because of the multigene involvement in autism, the MECP2 gene has only been identified as a vulnerability factor in autism. [63]
