Severe deficits in communication and cognitive ability are among the necessary diagnostic criteria for Rett syndrome (RTT), a progressive neurodevelopmental disorder that affects almost exclusively females. Traditional assessments, which rely on motor and verbal responding to assess comprehension and cognition, may not accurately reflect functioning in this population. To date, however, there are no comprehensive, systematic reviews of the literature regarding estimates of developmental and cognitive functioning in RTT. The purpose of this paper is to review the literature regarding functioning in comprehension, cognition, and adaptive behavior with a specific focus on the limitations of existing assessment approaches. Suggestions for future research are also discussed.
