Abstract
Due to medical advances, a large portion of children survive brain tumor diagnosis and treatment. Therefore, it is important to identify the neuroanatomical and neurocognitive outcomes associated with survivorship. This review summarizes the specific regional structural neuroimaging findings, the broad structural findings, as well as the corresponding neurocognitive domains affected in brain tumor populations. Across studies, damage is commonly reported near the cerebellum, brain stem, and subcortical regions, as well as the frontal lobes. These results are consistent with the expected neuroanatomical damage following posterior fossa brain tumors, which was the most common tumor location of the studies in this review. Damage to these regions impacts a broad range of neurocognitive outcomes, as well as a number of specific neurocognitive domains. Damage to more ventral and subcortical brain regions correlated with lower motor speed, processing speed, attention, and memory. Relevant limitations and future directions are discussed with a focus on disentangling the complex and multifaceted factors associated with the consequences of brain tumor survivorship.
