What Is Autism? Autism and autism spectrum disorders are complex brain disorders with a multi-factorial etiology. According to estimates from the Centers for Disease Control, 1 in 88 children in America are on the autism spectrum. Boys are 4 times more likely to have autism than girls.There is a strong genetic component to autism and 90% of autism is "idiopathic autism". Psychiatric comorbidity including mood, anxiety, and sleep disorders, schizophrenia, and movement disorders are extremely common in this population. One percent of the population meets DSM-IV criteria for intellectual disability, of which 85% is mild. Eating disorders like anorexia nervosa and bulimia nervosa are common. The lifetime prevalence of anorexia nervosa is around 1%, with 90% of the patients being female and Caucasian.
This section has clinically relevant and evidence-based videos on the diagnosis, etiology, comorbidity, treatment and symptoms of autism, eating disorders, personality disorders, and intellectual disability in children and adolescents. Extensive use of data from randomized controlled trials, meta-analyses, and the Cochrane Reviews is made for the discussion when applicable. Cochrane Reviews are systematic reviews of primary research in human health care and health policy, and are internationally recognized as the highest standard in evidence-based health care.
