Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS)
Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), pronounced as /pərˈveɪsɪv dɪˈvɛləpməntəl ˈdɪsɔːdər nɒt ˈʌðərwaɪz ˈspɛsɪfaɪd/, is a type of Autism Spectrum Disorder (ASD) that is characterized by delays in the development of socialization and communication skills. The term PDD-NOS is often used when the full criteria for other specific disorders, such as Autism or Asperger Syndrome, are not met.
Etymology
The term "Pervasive Developmental Disorder Not Otherwise Specified" is derived from the Diagnostic and Statistical Manual of Mental Disorders (DSM), where "pervasive" refers to the widespread nature of the developmental delays, "developmental disorder" refers to the onset during childhood, and "not otherwise specified" indicates that the symptoms do not fully meet the criteria for any other specific disorder within the ASD category.
Symptoms
Symptoms of PDD-NOS can vary widely, but typically include difficulties with social interaction, communication, and repetitive behaviors. These may include problems understanding and using language, difficulty relating to people, unusual play with toys, and difficulty with changes in routine or familiar surroundings.
Diagnosis
Diagnosis of PDD-NOS is typically made by a multidisciplinary team, including a psychologist, psychiatrist, neurologist, and/or pediatrician. The team will use a variety of assessment tools, including observation, parent interviews, and standardized tests.
Treatment
Treatment for PDD-NOS often involves a combination of behavioral therapy, speech therapy, occupational therapy, and physical therapy. Medication may also be used to manage associated symptoms such as anxiety or hyperactivity.
