What is Rett Syndrome ?
Rett Syndrome is an inherited disorder of the nervous system and which causes reversals of development. These developmental reversals are more prominent in the use of expressive language and the hands.
Rett syndrome is exclusively prevalent in girls. Boys who develop the disorder die very early. Girls with the disorder may grow and learn normally, but after a few years the development stops and the loss of skills start.
Rett Syndrome Symptoms
Some of the symptoms of Rett syndrome are listed below:
- The development of an individual undergoes many changes and reversals.
