| Popis: | Late effects of radiotherapy on intellectual functioning have been well documented in children treated for posterior fossa tumors. Other aspects of cognitive functioning, such as memory, have not been adequately assessed in this population. This retrospective review reports on 15 children diagnosed with medulloblastoma or cerebellar astrocytoma who were administered a norm-referenced standardized test of memory functioning (i.e., Wide Range Assessment of Memory and Learning) an average of 3.5 years after treatment. Analyses revealed that sample means of IQ and memory were significantly lower than those of the normative population. No significant differences were found between the verbal and nonverbal IQ, or verbal and visual memory. Age at diagnosis accounted for a significant proportion of variability in the intelligence ratings but not in the memory indexes. The IQ scores of children less than 6 years of age at diagnosis were significantly lower than those of children diagnosed when over 6 years of age. Given the substantial variability within the older age group, there was insufficient power to detect true differences between memory index means for children by age at diagnosis. Follow-up assessments over 5 years may better identify the long-term effects of radiotherapy on memory functioning. |
