What is Rett's Autism?
February 11, 2026
The term
“Rett’s autism” is sometimes used to describe
Rett syndrome, a rare genetic neurological disorder that primarily affects girls. While Rett syndrome shares traits with
autism, such as challenges in communication, social interaction, and repetitive behaviors, it is not the same condition.
Rett syndrome is caused by mutations in the
MECP2 gene, leading to developmental regression after a period of typical early growth.
Children with Rett syndrome may lose previously acquired skills, struggle with motor control, and develop repetitive hand movements. Because these features overlap with autism spectrum disorder (ASD), Rett syndrome was historically grouped under the autism category. Today, however, it is recognized as a distinct disorder, though understanding the similarities helps families and professionals provide better support.
For parents and caregivers, knowing the difference between autism and Rett syndrome is crucial. It ensures children receive the right interventions and therapies tailored to their unique needs.
