Quizplus · Accepted Answer

The disorder described is Rett syndrome, which is characterized by normal development for up to 4 years, followed by regression and intellectual disabilities. It is a genetic disorder that primarily affects girls. Asperger syndrome is a type of autism spectrum disorder characterized by social difficulties and repetitive behaviors, but without significant delay in language and cognitive development. Childhood disintegrative disorder is a rare condition in which a child develops normally for several years, but then experiences significant loss of previously-acquired skills. Pervasive developmental disorder is a term used to describe a group of disorders that include autism spectrum disorders, but is not a specific diagnosis.
