The Diagnostic and Statistical Manual of Mental Disorders, Fifth Addition (DSM-5) identifies countless mental disorders, such as autism (“DSM-5 Development of American Psychiatric Association).

(“Prevalence”). This statistic reveals an increasing frequency of the disorder, since the prevalence just two years ago was 1 in 88, and thirty years ago the disorder was present in 1 in 10,000 (“Prevalence”). With such increasing rates of pervasiveness, it is in people's best interest to become familiar with this disorder. Autism can be diagnosed based on symptoms that can vary widely in severity. Most cases can be identified between 6 and 18 months of age, with notable disruptions in areas such as developmental rates and sequence of motor, social, and cognitive skills.
