According to the Diagnostic and Statistical Manual of mental Disorders, Fifth Edition (DSM-5), Autism Spectrum Disorder (ASD) is a brain disorder affecting communication and social interactions. It occurs before three years of age. Signs of autism include: repetitive behaviors, impairments in verbal and non-verbal communication and difficulties with socialization.
Autism Spectrum Disorder is a general term used to communicate an individual’s challenges. Persons functioning on the autism spectrum share similar features but their skills and deficits may vary widely. A person living on the autism spectrum will display varying degrees of challenges in the area of social functioning, verbal and nonverbal communication and repetitive behaviors. Until recently, subtypes of ASD were used to further communicate areas of functioning. These subtypes of Pervasive Disorder Not Otherwise Specified (PDD-NOS), Asperger Syndrome, autistic disorder and childhood disintegrative disorder are not included in the DSM-5 and are no longer used in the classification of ASD.
Autism is treatable.
