Autism, Rett syndrome, and Asperger syndrome are just a few of the conditions that are classified as a pervasive developmental disorder (PDD). This term covers a wide range of behaviors and abilities, as people with PDD differ greatly in the way they act and what they can do. In addition, a symptom might be mild in one person and severe in another.
Some examples of PDD symptoms include problems with:
- Speech, language, and communication
- Social skills
- Repeated routines and behaviors.
When treating PDD, a person's therapy should be specialized according to need. For example, medications can be used to address certain behavioral problems. Managing a child's educational environment through small class sizes or one-on-one instruction can also be helpful.
