van der Meulen et al. show that both systemic and inhaled glucocorticoid use are associated with an apparently widespread reduction in white matter integrity, which may in part underly the neuropsychiatric side effects observed in patients using glucocorticoids. Image credit: Steve Buissinne.

$Overview of observed standardized regression coefficients (b values) for the associations between total body fat and fractional anisotropy (FA)- and mean diffusivity (MD)-based DTI tracts for men and women. Standardized regression coefficients reflect the standard deviation (SD) change in FA and MD, respectively, per standard deviation (6.5% in women and 5.5% in men) change in total body fat. Results were adjusted for age, ethnicity, Townsend deprivation index, assessment center (baseline visit and imaging visit), smoking, alcohol use, diabetes, cardiovascular disease, and intracranial volume.
