Popis: Aging is characterized by a decreased ability to adapt. The neurotoxicity/cascade hypothesis highlights causality of adrenal glucocorticoid and mineralocorticoids in acceleration of brain aging during chronic stress. The susceptibility/vulnerability hypothesis depends on (early) stressful life experiences and metabolism that prime brain circuits for coping with future challenges. These actions exerted by the steroids are mediated in complementary fashion by mineralocorticoid receptors (MR) and glucocorticoid receptors (GR). A balanced MR:GR function maintains stability and promotes resilience as a determinant in aging and age-related pathology.
