Children with PDD or autism vary widely in abilities, intelligence, and behaviors. Some children do not speak; others have limited language that often includes repeated phrases or conversations. People with more advanced language skills tend to use a small range of topics and have difficulty with abstract concepts. Repetitive play skills, a limited range of interests, and impaired social skills are generally evident as well. Unusual responses to sensory information are also common. Some or all of the following characteristics may be observed in mild to severe forms: communication problems; difficulty in relating to people, objects, and events; unusual play with toys and other objects; difficulty with changes in routine or familiar surroundings; and repetitive body movements or behavior patterns. The following disorders all fall under PDD: Autistic Disorder, Childhood Disintegrative Disorder, Retts Syndrome, Aspergers Continuum Syndrome and Pervasive Developmental Disorders – Not Otherwise Specified.
a developmental disability similar to autism but with fewer abnormal symptoms
Disorders characterized by severe and pervasive impairments in several areas of development such as social skills, communication skills, or sterotyped behaviors, interestes, and activities. PDDs include several disorders including austim and Asperger disorder.
Category includes children who behave in egocentric ways, but do not have the language issues or meet the other criteria of Asperger's or autistic disorder. If the disorders were compared to a virus, PDD is milder than Asperger's or autistic disorder which are more virulent.
is used as a non-specific, generic term referring to a group of related disorders which share certain essential features: qualitative impairments in both verbal and non-verbal communication, difficulty with reciprocal social interaction and a restricted stereotypic pattern of behaviours. The most well known example of PDD is autism.
A broad class of severe developmental disorders with onset during infancy or early childhood characterized by stereotyped behaviors and impairments in numerous developmental areas of functioning, including communication skills and social interactions with peers
The category of special education services for students with delays or deviance in their social/language/motor and/or cognitive development.
Characterized by severe and pervasive impairment in several areas of development: reciprocal social interaction skills, communication skills, or the presence of stereotyped behavior, interests and activities. The qualitative impairments that define these conditions are distinctively deviant relative to the individuals' developmental level or mental age. These disorders consist of Autistic Disorder, Rett Syndrome, Childhood Disintegrative Disorder, Asperger Syndrome, and Pervasive Developmental Disorder Not Otherwise Specified.
1. Extreme distortions or delays in the development of social behavior and language. 2. A term used to describe drug exposure to children while in the womb. Results of this exposure can cause extremely short attention spans. Behavior disorders, limited or no processing skills, and/or difficulty understanding spoken words.
a neurobiological disorder that affects a child’s social, mental, linguistic, and physical development. Examples include autism, Rhett’s disorder, conduct disorder, oppositional defiant disorder as well as motor, speech and language needs. Children with PDD often experience behavioral, emotional, occupational, physical, and other therapies.
A defined category of disability that involves problems in social interaction and verbal and nonverbal communication. PDD includes autism, childhood disintegrative disorder, Rett Syndrome, Asperger's syndrome, and PDD-not otherwise specified as diagnostic entities. PDD not otherwise specified (PDD-NOS) refers to children who have autistic symptoms but do not formally qualify for that diagnosis.
a neurobiological disorder that affects a child's social, mental, linguistic, and physical development. Examples include autism, Rhett's disorder, conduct disorder, and oppositional defiant disorder. Children with PDD often experience behavioral, emotional, and motor problems, and need speech, language, occupational, physical, and other therapies.
a group of disorders characterised by severe and pervasive impairments is several areas of development: reciprocal social interaction skills; communication skills; or the presence of stereotyped behaviour, interests, and activities. Also called Autism Spectrum Disorders.
The diagnostic category pervasive developmental disorders (PDD), as opposed to specific developmental disorders (SDD), refers to a group of disorders characterized by delays in the development of multiple basic functions including socialization and communication. The most commonly known PDD is autism. Parents may note symptoms of PDD as early as infancy and typically onset is prior to 3 years of age.
