The relationship between radiotherapy dose and cognitive outcomes in functional brain network hubs of glioma patients with predominantly left frontal lobe lesions.

ABSTRACT: Emerging evidence suggests that cognitive dysfunction may result from damage to the brain's functional network. This study explores the dose-dependent susceptibility of functional hubs to radiotherapy (RT) and associations with cognitive outcomes. Attention, language, memory, motor, and executive functioning were assessed ≥1-year post-radiotherapy in 39 WHO grade 2 or 3 glioma patients with lesions predominantly located in the left frontal lobe and 50 matched healthy controls. Using resting-state functional imaging, weighted functional graphs were constructed for each participant, identifying hubs through graph measures. Linear regression models and Spearman's rho correlations assessed associations between mean RT dose per region and cognitive domains. Higher RT doses to the left fusiform
