Chronically elevated glucocorticoid (GC) level impairs cognition. In rodents, elevated plasma GC levels, prior to an inflammatory challenge, potentiates neuroinflammation that is abolished by GR but not MR antagonism. 11β-hydroxysteroid dehydrogenase type-1 (11β-HSD1) increases intracellular GC levels by regenerating active GCs from inert forms. Inhibition/deficiency of 11β-HSD1 is protective against age-related cognitive decline presumably by lifelong reduced b...
