Rett syndrome (RTT) is a developmental disorder affecting
mainly females, due to the origin of the affected gene on
the X-chromosome. Aim: To identify undiagnosed adults
with RTT living in residential centers in Israel. Population:
3,144 adult women with developmental disability residing
in residential care centers for individuals with intellectual
and developmental disabilities (IDD). Procedure: A national survey was conducted in all 63 residential care centers, were all participants were evaluated through observation (according to the clinical characteristics of RTT), staff interviews and medical record screening. Results: One hundred and seventy four (174) females (6.4%of all female residents) were suspected of RTT ranging in ages 12-76 years. Conclusions: Adults with RTT can be identified and clinically diagnosed by a person familiar with the characteristics of RTT. Identifying these clients will enable the clinician to suggest better care and management for this population, as well as to improve the care given today to young people diagnosed with this disorder in accordance with the prognosis of adults with RTT.
