Gout strongly associated with reduced gray matter and increased neurodegenerative disease
by Justin Jackson, Medical Xpress Differences in regional gray matter volume between participants with gout (n = 1,165) and controls (n = 32,202), as analyzed by voxel-based morphometry. Blue regions represent areas where participants with gout had significantly less gray matter. T statistics are thresholded at a 5% false discovery rate (0.0013 threshold on uncorrected P values). Models adjusted...
