Pervasive developmental disorder (PDD) is a group of neurodevelopmental disorders that affect an individual’s ability to communicate, socialize, and engage in repetitive behaviors. PDD is a broad term that encompasses several different types of disorders, including autism spectrum disorder, Asperger’s syndrome, childhood disintegrative disorder, Rett syndrome, and pervasive developmental disorder not otherwise specified (PDD-NOS). In this article, we will explore what PDD is and the different types of disorders that fall under this umbrella term.
Definition of Pervasive Developmental Disorder
Pervasive developmental disorder is a term that refers to a group of neurodevelopmental disorders that are characterized by impairments in social interaction, communication, and behavior. PDD is a broad term that encompasses several different types of disorders, each with its own set of symptoms and diagnostic criteria.
Types of Pervasive Developmental Disorder
There are several different types of PDD, each with its own set of symptoms and diagnostic criteria. The different types of PDD include:
Autism Spectrum Disorder (ASD): Autism spectrum disorder is a neurodevelopmental disorder characterized by difficulties in communication and social interaction, as well as repetitive behaviors and restricted interests. Symptoms of ASD can range from mild to severe, and can have a significant impact on an individual’s social, academic, and occupational functioning.
Asperger’s Syndrome: Asperger’s syndrome is a type of PDD characterized by difficulties in social interaction and communication, as well as restricted interests and repetitive behaviors. Individuals with Asperger’s syndrome typically have average or above-average intelligence, and may have difficulty with nonverbal communication and social cues.
Childhood Disintegrative Disorder: Childhood disintegrative disorder is a rare type of PDD characterized by a significant loss of previously acquired skills in communication, social interaction, and play. This loss typically occurs between the ages of 2 and 4, and can have a significant impact on an individual’s social, academic, and occupational functioning.
Rett Syndrome: Rett syndrome is a rare genetic disorder that primarily affects females. Symptoms of Rett syndrome typically appear between 6 and 18 months of age, and can include a loss of previously acquired skills, difficulties with communication and social interaction, and repetitive hand movements.
Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS): PDD-NOS is a type of PDD that does not meet the diagnostic criteria for autism, Asperger’s syndrome, or other specific PDDs. Individuals with PDD-NOS may have some symptoms of PDD, but not enough to meet the diagnostic criteria for a specific disorder.
Symptoms of Pervasive Developmental Disorder
The symptoms of PDD can vary widely depending on the individual and the specific disorder that is present. However, some common symptoms that have been associated with PDD include:
- Impairments in social interaction, such as difficulty with making and maintaining friendships, lack of interest in socializing, and difficulty with understanding social cues
- Impairments in communication, such as difficulty with verbal and nonverbal communication, delayed language development, and difficulty with understanding and using language appropriately
- Repetitive and stereotyped behaviors, such as rocking back and forth, flapping hands, and lining up objects
- Unusual interests or preoccupations, such as an intense interest in a specific topic or object
- Difficulty with transitions or changes in routine
- Sensory sensitivities, such as being overly sensitive to certain sounds or textures
How is pervasive developmental disorder treated
Early Intervention
Early intervention is key for individuals with PDD. Research has shown that early identification and intervention can lead to better outcomes for individuals with PDD. Early intervention services may include speech therapy, occupational therapy, and behavioral therapy. These services can help individuals with PDD to develop important skills in communication, social interaction, and behavior.
Behavioral Therapy
Behavioral therapy is a common treatment for PDD. Behavioral therapy focuses on teaching individuals with PDD new skills and behaviors, while also addressing problematic behaviors. Behavioral therapy can be delivered in a variety of settings, including the home, school, or clinic. Common types of behavioral therapy for PDD include applied behavior analysis (ABA) and cognitive behavioral therapy (CBT).
Medication
Medication is not a primary treatment for PDD, but it may be used to treat specific symptoms or co-occurring conditions. For example, medication may be used to treat anxiety, depression, or hyperactivity. It is important to note that medication should only be used under the guidance of a licensed healthcare provider.
Educational Support
Individuals with PDD may benefit from educational support, such as special education services or individualized education plans (IEPs). Educational support can help individuals with PDD to develop important academic and social skills, while also addressing their unique needs and challenges.
Parent Training and Support
Parent training and support can be an important aspect of treatment for PDD. Parents of children with PDD may benefit from training on how to effectively manage problematic behaviors, communicate with their child, and support their child’s development. Parent support groups can also provide a valuable source of emotional support and information.
Conclusion
Pervasive developmental disorder is a group of neurodevelopmental disorders that affect an individual’s ability to communicate, socialize, and engage in repetitive behaviors. Autism spectrum disorder, Asperger’s syndrome, childhood disintegrative disorder, Rett syndrome, and PDD-NOS are all types of PDD, each with its own set of symptoms and diagnostic criteria. If you or someone you know may have a PDD, it is important to seek the advice of a licensed mental health professional for an accurate diagnosis and appropriate treatment.
