Question: What are the treatments for Rett Syndrome ?
Answer: There is no cure for Rett syndrome. Treatment for the disorder is symptomatic, focusing on the management of symptoms, and supportive. Medication may be needed for breathing irregularities and motor difficulties, and antiepileptic drugs may be used to control seizures. Occupational therapy, physiotherapy, and hydrotherapy may prolong mobility. Some children may require special equipment and aids such as braces to arrest scoliosis, splints to modify hand movements, and nutritional programs to help them maintain adequate weight. Special academic, social, vocational, and support services may be required in some cases.

Question: What is the outlook for Rett Syndrome ?
Answer: The course of Rett syndrome, including the age of onset and the severity of symptoms, varies from child to child. Despite the difficulties with symptoms, most individuals with Rett syndrome continue to live well into middle age and beyond. Because the disorder is rare, very little is known about long-term prognosis and life expectancy.
