As a group, children with low-grade gliomas (LGGs) enjoy a high rate of long-term survival and do not require the intensity of neurotoxic treatments used with higher risk pediatric brain tumors. Because they are generally considered to have favorable neurobehavioral outcomes, they have not been studied as thoroughly as higher-grade brain tumors by late-effects researchers. In this article, we review the literature on the neurobehavioral effects associated with low-grade gliomas and conclude that, (1) this is a large, understudied group of survivors of pediatric brain tumors; (2) recent small- and large-scale studies document increased risk in multiple cognitive-behavioral domains after treatment for LGGs compared with healthy peers; (3) such risk is not uniform but varies with tumor location and treatments; and (4) a life span development perspective is essential to a complete understanding of the risks faced by these children. More research on the most efficacious biopsychosocial treatment models for improving the outcomes of survivors of low-grade glioma is recommended, informed by a better understanding of theireducational needs. Investigations of genetic influences on outcome as well as prospective studies of these patients as they age are also recommended.
