Working memory abilities among children treated for medulloblastoma: Parent report and child performance

Abstract

ObjectiveWe investigated the 5-year postsurgical developmental trajectory of working memory (WM) in children with medulloblastoma using parent and performance-based measures.MethodThis study included 167 patients treated for medulloblastoma. Serial assessments of WM occurred at predetermined time points for 5 years.Results There was a subtle, statistically significant increase in parental concern about WM, coupled with a statistically significant decrease in age-standardized scores on performance-based measures. However, whole-group mean scores on both parent and performance-based measures remained in the age-expected range. Posterior fossa syndrome was consistently associated with poorer WM..
