[The HPA-axis as a possible link between depression, diabetes mellitus and cognitive dysfunction].
Patients suffering from diabetes mellitus and depressive patients show a hyperactivity of the hypothalamic-pituitary-adrenocortical axis (HPA-axis) with hypercortisolemia. Hypercortisolemia is associated with cognitive dysfunction. These neuroendocrinological disturbances can cause an insulin resistance syndrome which complicates the regulation of blood glucose. Cognitive and depressive disorders in patients with diabetes mellitus might be associated with a hyperactivity of the HPA-axis. By normalising the HPA-axis both disorders could be improved. In addition, one can expect that antidepressive treatment with normalization of the HPA-axis could improve the metabolic situation and cognitive dysfunction. There is need for further research to study the associations between depression, diabetes mellitus and cognitive dysfunction.
