Decisions about the best treatment, or combination of treatments, should be made by the parents with the assistance of a trusted expert diagnostic team. Autism (a developmental brain disorder characterized by impaired social interaction and communication skills, and a limited range of activities and interests) is the most characteristic and best studied PDD. Dive into the research topics of Autism and pervasive developmental disorders. There is no single best treatment package for all children with ASD. When an affectionate, babbling toddler suddenly becomes silent, withdrawn, self-abusive, or indifferent to social overtures, something is wrong. The first signs of an autism spectrum disorder can also appear in children who had been developing normally. It refers to individuals who do not meet the diagnostic criteria for any of the four other pervasive. In some cases, the baby seemed "different" from birth, unresponsive to people or focusing intently on one item for long periods of time. Pervasive developmental disorders include five different conditions: Aspergers syndrome, autistic disorder, childhood disintegrative disorder (CDD). PDD-NOS can often be referred to as Atypical Autism.
Parents are usually the first to notice unusual behaviors in their child. The Centers for Disease Control and Prevention (CDC) estimates that 1 in 68 American children has ASD.
They also include two rare disorders, Rett syndrome and childhood disintegrative disorder. Pervasive developmental disorder is a type of autism. These disorders are usually first diagnosed in early childhood and range from a severe form, called autistic disorder, through pervasive development disorder not otherwise specified (PDD-NOS), to a much milder form, Asperger syndrome. Autism spectrum disorders (ASD), also known as pervasive developmental disorders (PDDs), cause severe and pervasive impairment in thinking, feeling, language, and the ability to relate to others.
