Autism is included in the Diagnostic and Statistic Manual 5 (DSM5, 2013) under the broad category of Neurodevelopmental Disorders. It is now diagnosed with a dyad of impairments instead of a triad and is termed Autism Spectrum Disorders. The term Pervasive Developmental Disorders is no longer in use.
The following points contain the Diagnostic criteria for Autism Spectrum Disorder according to DSM V:
1. Persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following, currently or by history (examples are illustrative, not exhaustive):
2. Restricted, repetitive patterns of behaviour, interests, or activities, as manifested by at least two of the following, currently or by history (examples are illustrative, not exhaustive;)
3. Symptoms must be present in the early developmental period (but may not become fully manifest until social demands exceed limited capacities, or may be masked by learned strategies in later life).
4. Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.
These disturbances are not better explained by intellectual disability (intellectual developmental disorder) or global developmental delay. Intellectual disability and autism spectrum disorder frequently co-occur; to make comorbid diagnoses of autism spectrum disorder and intellectual disability, social communication should be below that expected for general developmental level. This might be a cohesive explanation of autism but is not explanation enough to describe children or people have it. Autism may have a pattern but does not reincarnate in every child in identifiably similar ways. The variation in the degree of autism is proof to their uniqueness. Hence, the truth of children with autism lies far beyond the mere identification of the disorder.
