Delusional or unconventional perception of the world.Difficulty regulating behaviors and emotions, which may result in temper tantrums, anxiety, and aggression.Repetitive body movements or behavior patterns, such as hand flapping, hair twirling, foot tapping, or more complex movements.Paranoia, a characteristic form of social anxiety, derealization, transient psychosis, and unconventional beliefs if environment or routine are changed without notice.Unusual play with toys and other objects.Difficulty relating to people, objects, and events for example, lack of eye contact, pointing behavior, and lack of facial responses.Difficulty using and understanding language.Symptoms of PDD may include behavioral and communication problems such as: Both approaches contribute to confusion about the term, because the term PDD actually refers to a category of disorders and is not a diagnostic label. Others use the general category label of PDD because they are hesitant to diagnose very young children with a specific type of PDD, such as autism. Many use the term PDD as a short way of saying PDD-NOS ( pervasive developmental disorder not otherwise specified). There is a division among doctors on the use of the term PDD.

Parents may begin to question the health of their child when developmental milestones are not met, including age appropriate motor movement and speech production. The onset of pervasive developmental disorders occurs during infancy, but the condition is usually not identified until the child is around three years old. ICD-10 on the other hand labels ASD as a pervasive developmental disorder with the subtypes previously mentioned. DSM-5, removed PDD as a diagnosis and replaced it with ASD and the relative severity of the condition.

The two have overlapping definitions but are defined differently by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), and the International Classification of Diseases, 10th edition (ICD-10). The terminology PDD and ASD is often used interchangeably and varies depending on location. The first four of these disorders are commonly called the autism spectrum disorders the last disorder is much rarer, and is sometimes placed in the autism spectrum and sometimes not. The pervasive developmental disorders include autism, Asperger syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS, i.e., all autism spectrum disorders ), childhood disintegrative disorder (CDD), overactive disorder associated with mental retardation and stereotyped movements, and Rett syndrome. The diagnostic category pervasive developmental disorders ( PDD), as opposed to specific developmental disorders (SDD), is a group of disorders characterized by delays in the development of multiple basic functions including socialization and communication.
