Imitation and utilization behaviour (IB ; UB) have been described in lesions or deafferentations of the frontal lobes. Both reflect a loss of the patients' autonomy. IB and UB having been encountered in a case of melancholia, a systematic study has been undertaken in psychiatric departments. Sixty patients have been examined among whom 18 had a major depressive episode and 19 a dysthymic episode. IB or UB or both were present in every case of the first group, in 3 cases of the second one. Such data show first an unexpected focal specific neurological sign in a psychiatric disease. Second, they suggest a relationship with the frontal hypoactivity shown by PET studies in major depressive episodes. Such frontal hypoactivity should not be viewed as the cause of major depression but as a concomitant disorder. Its role in the awareness and expression of the thymic disturbance is discussed.

State-of-the-art navigated transcranial magnetic stimulation (nTMS) systems can display the TMS coil position relative to the structural magnetic resonance image (MRI) of the subject's brain and calculate the induced electric field. However, the local effect of TMS propagates via the white-matter network to different areas of the brain, and currently there is no commercial or research neuronavigation system that can highlight in real time the brain's structural connections during TMS. This lack of real-time visualization may overlook critical inter-individual differences in brain connectivity and does not provide the opportunity to target brain networks.

Background: Although psychological interventions can be effective for the treatment of major depressive disorder, some patients' symptoms persist or rapidly recur after therapy. This study aimed to synthesize research findings on predictors and moderators of treatment response for persisting forms of depression, such as chronic, recurrent, and treatment-resistant depression.
Methods: A systematic review of studies investigating predictors and moderators of response to outpatient psychological treatment for adults with persisting forms of depression was conducted by searching Web of Science, Scopus, and PsycInfo.

Background: Major depression is classified into distinct subtypes: simple (SDMD) and major dysmood disorder (MDMD). MDMD patients exhibit elevated atherogenicity and decreased reverse cholesterol transport (RCT). However, comprehensive data regarding lipid metabolism is absent in first episode (FE)-SDMD.
