Although Rett syndrome (RS) was first described by Andreas Rett in 1966, this disorder became internationally recognized only after the report of Hagberg et al. in 1983. It is a neurodevelopmental disorder which affects almost exclusively girls and is associated with deceleration of head growth, typical stereotyped hand movements, severe mental deficiency, cortical and extrapyramidal dysfunction including gait disturbance and truncal ataxia as well as loss of purposeful use of the hands.
