Induction of response to psychotropic medications in depression and panic after concurrent treatment of diabetes.

We present a case of depression with panic disorder, which did not respond to adequate psychiatric interventions over a period of several months. However, it improved completely with the diagnosis and treatment of diabetes mellitus. Hence, we infer that comorbid diabetes mellitus can render depression resistant to psychiatric interventions and must always be ruled out when treating patients who show poor response to adequate interventions for an adequate period of time.
