What Is Autism?

The Center for Disease Control (CDC) defines Autism as: “a group of developmental disabilities that can cause significant social, communication and behavioral changes”.

The definition of Autism provided by Autism Speaks states that: “Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. With the May 2013 publication of the DSM-5 diagnostic manual, all autism disorders were merged into one umbrella diagnosis of ASD. Previously, they were recognized as distinct subtypes, including autistic disorder, childhood disintegrative disorder, pervasive developmental disorder-not otherwise specified (PDD-NOS) and Asperger syndrome. ASD can be associated with intellectual disability, difficulties in motor coordination and attention and physical health issues such as sleep and gastrointestinal disturbances. Some persons with ASD excel in visual skills, music, math and art.”

Similar to the CDC and Autism Speaks definitions of Autism, the definition of Autism provided by the Mayo Clinic states: “Autism spectrum disorder is a serious neurodevelopmental disorder that impairs a child’s ability to communicate and interact with others. It also includes restricted repetitive behaviors, interests and activities. These issues cause significant impairment in social, occupational and other areas of functioning. Autism spectrum disorder (ASD) is now defined by the American Psychiatric Association’s Diagnosis and Statistical Manual of Mental Disorders (DSM-5) as a single disorder that includes disorders that were previously considered separate — autism, Asperger’s syndrome, childhood disintegrative disorder and pervasive developmental disorder not otherwise specified. The term “spectrum” in autism spectrum disorder refers to the wide range of symptoms and severity. Although the term “Asperger’s syndrome” is no longer in the DSM, some people still use the term, which is generally thought to be at the mild end of autism spectrum disorder.

Lastly, Autism is defined in the Merriman Webster Dictionary as: “a developmental disorder that appears by age three and that is variable in expression but is recognized and diagnosed by impairment of the ability to form normal social relationships, by impairment of the ability to communicate with others, and by stereotyped behavior patterns especially as exhibited by a preoccupation with repetitive activities of restricted focus rather than with flexible and imaginative ones.”

In summary, it can be said that, Autism is a neurologically based developmental disability that seriously affects a person’s ability to communicate, socialize, make judgments, and understand the perspectives of others. Autism is a spectrum disorder that affects every individual differently. The degree to which autism symptoms affect each person varies greatly.
