Impairments of attention following treatment with cranial irradiation and chemotherapy in children

Abstract

Neurobehavioral impairments are frequently reported following treatment for childhood cancers, with cranial irradiation (CRT). This study investigated attention and information processing skills, predicting that these skills would be impaired due to the vulnerability of cerebral white matter in early childhood. Three treatment groups were studied: (i) CRT+chemotherapy (n = 35); (ii) chemotherapy alone (n = 19); (iii) healthy children (n = 35). All children were aged 9 to 16 years at time of assessment, with no pre-diagnosis history of neurologic, developmental, or psychiatric disorder. Children were administered a series of tasks measuring processing speed and sustained, selective, and shift..
