Lack of access to appropriate medical care, broadening diagnostic criteria and increased awareness surrounding ASD in recent years has resulted in an increased number of individuals receiving a diagnosis of ASD as adults. Diagnosis of ASD in adults poses unique challenges because it still relies on an accurate developmental history and because ...
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.

The mirror neuron system (MNS) theory of autism hypothesizes that disrupted development of the MNS impairs autistic people's ability to imitate others, leading to core autistic features of social impairment and communication difficulties. In animals, the MNS activates when an animal performs an action or observes another animal perform the same ...

The protocol consists of a series of structured and semi-structured tasks that involve social interaction between the examiner and the person under assessment.
[9] [10] For adult diagnosis, clinicians identify neurodevelopmental history, behaviors, difficulties in communication, limited interests and problems in education, employment, and social relationships. Challenging behaviors may be assessed with functional analysis to identify the triggers causing them. [11]
Autism, or autism spectrum disorder [a] (ASD), is a neurodevelopmental disorder characterized by repetitive, restricted, and inflexible patterns of behavior, interests, and activities, as well as deficits in social communication and social interaction, and the presence of high or low sensory sensitivity.
The ICD-10 equivalents also became part of its definition of autism spectrum disorder, as of the ICD-11. PDD-NOS included atypical autism, a diagnosis defined in the ICD-10 for the case that the criteria for autistic disorder were not met because of late age of onset, or atypical symptomatology, or both of these.

The Autism Treatment Evaluation Scale (ATEC) is a 77-item diagnostic assessment tool that was developed by Bernard Rimland and Stephen Edelson at the Autism Research Institute. The ATEC was originally designed to evaluate the effectiveness of autism treatments, but it may also be beneficial as a screening tool for children.
