What is (are) Rett Syndrome ?
Rett syndrome is a childhood neurodevelopmental disorder that affects females almost exclusively. The child generally appears to grow and develop normally, before symptoms begin. Loss of muscle tone is usually the first symptom. Other early symptoms may include a slowing of development, problems crawling or walking, and diminished eye contact. As the syndrome progresses, a child will lose purposeful use of her hands and the ability to speak. Compulsive hand movements such as wringing and washing follow the loss of functional use of the hands. The inability to perform motor functions is perhaps the most severely disabling feature of Rett syndrome, interfering with every body movement, including eye gaze and speech.
