With such increasing rates of pervasiveness, it is in the interest of populations to familiarize themselves with this disorder. Autism can be diagnosed based on symptoms that can vary widely in severity. Most cases can be identified by the age of 6-18 months, with notable disturbances in areas such as developmental rates and sequencing of motor, social and cognitive skills.
