What is Rett syndrome?

Rett syndrome was first reported by Dr. Andreas Rett in 1966. Rett syndrome is a complex neurological and developmental disorder in which early growth and development appear normal at first, but then the infant stops developing and affected children even lose skills and abilities.1 Rett syndrome occurs mostly in females.

Over time, the effects of Rett syndrome can lead to cognitive, sensory, emotional, motor, cardiac, and such autonomic (pronounced aw-tuh-NOM-ik) nervous system problems as difficulties with digestion or breathing.2
