Incidental findings of brain magnetic resonance imaging in patients with treatment-resistant depression

Aim: In this study, incidental findings of brain magnetic resonance imaging (MRI) of patients diagnosed with treatment-resistant depression (TRD) were compared with healthy controls (HC). Materials and Methods: The study included 68 patients with TRD (42 females, 26 males) and 72 HC (35 females, 37 males). Global assessment scale (GAS) was administered. Results: In the TRD group, those with general cerebral atrophy were found to have significantly lower global assessment scale (GAS) scores (p<0.001). In the TRD group, those with cavum veli interpositi (CVI) were found to have significantly lower GAS scores (p=0.001). In the TRD group, when the effect of age was controlled, a significant correlation was found between the GAS score and the duration of the disorder (r=-0.400; p=0.001). Conclusion: CVI, a neurodevelopmental abnormality, has been shown to be more common in patients diagnosed with TRD.
