Reduced Dynamic Brain Activity and Functional Connectivity in Nonfunctioning Pituitary Adenomas with Visual Impairment [RESEARCH]

BACKGROUND AND PURPOSE:
Visual disturbance is a major complication in nonfunctioning pituitary adenoma (NFPA) due to chiasmal compression. While neuroimaging studies have established brain dysfunction in visually impaired patients from chiasmal compression, the brain dynamic features of spontaneous activity and functional connectivity remain underexplored. This cross-sectional study aims to explore changes in temporal variability of spontaneous activity and connectivity in visually impaired pati…
