Résumé
Depression and diabetes are strongly related with bidirectional links and when together they are associated with a poor prognosis of both disorders.
Depression should not be considered as a normal suffering in patients presenting a chronic illness.
Informing patients and their family about the depressive risk and a regular screening of depression would be helpful to diagnose the disorder earlier and better in diabetic patients.
The adequate treatment of depression would be beneficial for both depressive disorder and glycaemic control.
Collaborative care for patients presenting chronic medical illness and depression represent a promising strategy.
