Obesity and major depression: Body-mass index (BMI) is associated with a severe course of disease and specific neurostructural alterations

In MDD, obese subjects might be characterized by a more chronic course of disease. Moreover, obesity and chronicity of disorder seem to share overlapping neurostructural anomalies in prefrontal areas involved in emotion regulation and impulse control. Hence, our data provide evidence for specific morphological alterations underlying this prevalent comorbidity. It further underlines the clinical importance of preventive measures against obesity accompanying MDD treatment.
