Diploma in Special Education (Autism Spectrum Disorder) - Autism spectrum disorders (ASDs) is a neurological disorder. It is defined as a group of developmental disorders mainly characterized by atypical development in socialization, communication, cognitive and behavioral functioning, learning, attention, and sensory processing. Indicators of developmental problems typically are present prior to 3 years of age and become significantly visible/prevalent after 36 months of age. Experienced clinicians using accurate standardized methods can diagnose autism reliably in children as young as age 2 years.The term "spectrum disorders" is used to indicate that ASDs encompass a wide range of behaviorally defined conditions, which are diagnosed through clinical observation. These conditions all have some of the same or similar symptoms, but they differ in terms of when the symptoms kick-in, how severe they are, and the exact nature of the symptoms. Individuals with Asperger's disorder and PDD-NOS have fewer diagnostic symptoms of ASDs compared with autism, and their symptoms often are of a more mild impairments in nature. ASDs occur in all racial, ethnic, and socioeconomic groups and seemed to appear 4 times more likely in boys than in girls.
