Final answer:
Pervasive Developmental Disorders (PDD) are a group of neurodevelopmental disorders that affect communication, social interaction, and behavior. Examples of PDD include Autism Spectrum Disorder (ASD), Asperger syndrome, and Childhood Disintegrative Disorder.
Step-by-step explanation:
Pervasive Developmental Disorders (PDD) are a group of neurodevelopmental disorders that affect communication, social interaction, and behavior. They are characterized by deficits in social skills, language development, and repetitive patterns of behavior or interests. PDD includes conditions such as autism spectrum disorder (ASD), Asperger syndrome, and childhood disintegrative disorder. These disorders can vary in severity and can have a significant impact on an individual's daily functioning and quality of life.
- Autism Spectrum Disorder (ASD): ASD is a complex disorder that affects social interaction, communication, and behavior. Individuals with ASD may have difficulty with social skills, such as making eye contact or understanding nonverbal cues. They may also have repetitive behaviors or intense interests in specific topics.
- Asperger Syndrome: Asperger syndrome is on the milder end of the autism spectrum. Individuals with Asperger syndrome usually have average or above-average intelligence, but they may struggle with social interactions and understanding social norms.
- Childhood Disintegrative Disorder: Childhood disintegrative disorder is a rare condition where a child shows significant loss of previously acquired skills, such as language, social skills, and motor abilities.
Individuals with PDD may benefit from early intervention, therapy, and support to improve their social and communication skills, manage behaviors, and enhance their overall quality of life.
