Main condition: Rett Syndrome

Conditions: Rett Syndrome

What is Rett Syndrome?
Rett syndrome is a progressive neurological disorder in which individuals exhibit reduced muscle tone, autistic-like behavior, hand movements consisting mainly of wringing and waving, loss of purposeful use of the hands, diminished ability to express feelings, avoidance of eye contact, a lag in brain and head growth, gait abnormalities, and seizures. Hypotonia (loss of muscle tone) is usually the first symptom. The syndrome affects approximately 1 in every 10,000-15,000 live female births, with symptoms usually appearing in early childhood between ages 6 and 18 months. The cause of Rett syndrome is unknown.

Is there any treatment?
There is no cure for Rett syndrome; however, there are several treatments options. These include treatments for the orthopedic and learning disabilities and seizures that may occur in individuals with Rett syndrome. Some children may require special nutritional programs to maintain adequate weight.

What is the prognosis?
In spite of the severe impairments that characterize this disorder, the majority of individuals with Rett can be expected to reach adulthood, surviving at least into their 40s. However, the risk of death is increased. Sudden, unexplained death possibly from brainstem dysfunction with respiratory arrest often occurs.

What research is being done?
Basic research on Rett syndrome includes studies in the areas of neuropathology, neurochemistry, neuroimaging, nutrition, and genetics. The National Institute of Child Health and Human Development (NICHD) funds research on Rett syndrome.
