Rett syndrome (RTT) is a complex neurological disorder caused by an affected MECP-2 gene, primarily affecting females. In 2007, a reversal of typical clinical characteristics of MECP2 mice was performed successfully. The results suggest that similar reversals might be achieved in human patients with RTT in a foreseeable future. Nonetheless, this future cure will not be able to reverse already acquired disabilities and limitations, such as osteoporosis, muscle degeneration, orthopedic contractures, and functional loss attributed to a long sedentary life typical for this group of clients. Evidence suggests that many aspects of clients' well-being and functional status depend on the therapeutic interventions they receive. Findings from diverse, intensive therapeutic programs implemented both with mice and individuals with RTT imply that such programs can enhance longevity, communications, learning, well-being, functional ability, and other life aspects characterizing this syndrome.The authors therefore urge that individuals with this syndrome should be treated with an intensive intervention programs from childhood to maintain their optimal functional performance and medical condition so that maximal gains will be achievable for those individuals with the availability of the forthcoming genetic cure.
