How is Rett syndrome associated with autism?

ANSWER

Rett syndrome previously fell under the autism spectrum, but we now know that Rett’s syndrome is caused by genetics. It no longer falls under ASD guidelines. Children with Rett syndrome, primarily girls, start developing normally but then begin losing their communication and social skills. Beginning at the age of 1 to 4 years, repetitive hand movements replace purposeful use of the hands. Children with Rett syndrome are usually severely cognitively impaired.
