Investigating the relationship between COMT polymorphisms and working memory performance among childhood brain tumor survivors.

Background: Survivors of childhood brain tumors are at increased risk for neurocognitive impairments, including deficits in abilities supported by frontal brain regions. Catechol-O-methyltransferase (COMT) metabolizes dopamine in the prefrontal cortex, with the Met allele resulting in greater dopamine availability and better performance on frontally mediated tasks compared to the Val allele. Given the importance of identifying resiliency factors against the emergence of cognitive late effects, the current study examined the relationship between COMT genotype and working memory performance among childhood brain tumor survivors.

Establishing a pediatric cognitive rehabilitation program: insurance issues and clinical rationale.

Technological and medical advances have greatly improved survival rates for many disorders; therefore, more attention is being given to functional outcomes in individuals who have been diagnosed with neurological diseases or disorders. One example of such an endeavor consists of a cognitive rehabilitation program to improve attentional abilities. The current study uses a modification of the original Cognitive Remediation Program to address attentional deficits in children with a variety of neurological disorders.
