Adaptive functioning in ependymoma survivors

from academic skills such as reading and writing. Future directions include the development of patient-specific risk models to help inform parents about appropriate expectations, supports, and behavioral demands. Given the lack of a strong relationship with the trajectory of change in IQ, these results highlight a need to continue evaluating adaptive functioning as a separate yet important func- tional outcome for survivors of ependymoma. Further follow-up 5 to 10 years postirradiation will be needed to examine whether func- tional performance remains stable. These findings suggest that baseline performance and preirradiation factors may prove to be the strongest predictors of functional outcome. 1. Central Brain Tumor Registry of the United States.
