Introduction
Rett syndrome is a rare neurodevelopmental disorder caused by a genetic problem that occurs almost exclusively in girls and affects development after an initial 6-month period of normal development. Rett syndrome is caused by a genetic mutation. Symptoms include a decline in language and social skills after an initial period of normal development. Diagnosis is based on a doctor's observation of the child’s early growth and development and genetic testing. Treatment involves a multidisciplinary approach that is focused on the management of symptoms and educational support. Rett syndrome is a rare Definition of Developmental Disorders and genetic disorder diagnosed most often in girls. Affected boys are identified much less often than girls because affected male fetuses often die before birth. Girls with Rett syndrome are usually born after a full-term, uneventful pregnancy and delivery. Rett syndrome is caused by mutation of a gene or genes that are needed for brain development. It causes impaired social interactions, loss of language skills, and repetitive hand movements. Although many symptoms resemble those of an Autism Spectrum Disorders , including difficulties with social skills and communication, Rett syndrome is a separate disorder.
