Brief Summary
Depression and metabolic disorder (MetD) are two of the most common and debilitating disorders worldwide, occurring with significant rates of comorbidity. This is a major clinical challenge as the outcomes of both conditions are worsened. Studies have uncovered that depression and metabolic disorder are associated with chronic, low-grade inflammation. In brain circuit level, patients with depression are characterized with aberrant frontostriatal (FS) circuit connectivity and reduced activity level that also associated with metabolic comorbidity. In neurotransmitter level, the dopaminergic pathway, that could be feedback regulated by immune and metabolic factors, has long been known to involve in emotional and metabolic homeostasis. More importantly, this dopamine (DA) input is critical to shaping the FS circuit-level dynamic connectivity and plasticity. Therefore, this study hypothesizes that inflammatory and metabolic dysregulations on DA transmission link to the aberrant FS function that cause mood and metabolic syndromes. To clarify the underlying mechanisms, 90 patients who meet the DSM-5 diagnostic criteria of major depressive episode in either major depressive disorder or bipolar disorder are planned to be recruit. FS functional connectivity and activation, before and after receiving 10 Hz repetitive transcranial magnetic stimulation (rTMS) to left dorsolateral prefrontal cortex will be measured. Then systemically analyze participants' clinical symptomology, neurocognitive function, inflammation and metabolic status. Possible correlations between indices, the effects of rTMS and differences between groups will be tested. Results could provide a chance for further understanding the pathophysiology of depression with MetD and comparing between unipolar and bipolar depression, and developing brain circuit based non-invasive brain stimulation personalized treatment for depression with MetD to achieve a better outcome.

Outcome Measures
Primary Outcomes (12)
Change from baseline mood symptom severity at several timepoints over 3 months
Evaluation for disease severity by using the Hamilton Rating Scale for Depression (HAM-D) by trained senior psychiatrists. The same rater administers the scale for each patient.
Week 0, Week 1, Week 2, Week 3, Week 4, Week 8, Week 12.
Iowa gambling task (IGT) with functional MR imaging
The subject will be asked to turn a card from 4-decks voluntarily, and maximize gains and minimize losses during the game.
Week 0
Change from baseline functional connectivity maps at 3 months
A 2-sample independent t-test will be employed to analyze the functional connectivity maps using SPM 12. Statistical maps will be computed to identify changes in striatum-seeded functional connectivity for between-group comparisons. The age will be regressed out as a covariate of non-interest. Significance will be threshold at the uncorrected voxel level p=0.001, followed by the FWE- corrected cluster level p=0.05.
Week 0, Week 12
Change from baseline homeostasis model assessment-estimated insulin resistance (HOMA-IR) index at several timepoints within 3 months
The homeostasis model assessment-estimated insulin resistance (HOMA-IR) index is calculated as the product of the fasting plasma insulin level (uIn/ml) and the fasting plasma glucose level (mg/dl), divided by 405. Insulin resistance is defined as HOMA-IR ≥2.5.
Week 0, Week 4, Week 8, Week 12
Change from baseline body mass index (BMI) at several timepoints within 3 months
Body weight (to the nearest 0.1 kg), body height (to the nearest 0.1 cm) will be measured and BMI (kg/m2) will be calculated accordingly.
Week 0, Week 4, Week 8, Week 12
Change from baseline waist and hip circumference at several timepoints within 3 months
Waist and hip circumference (to the nearest 0.1 cm) will be measured.
Week 0, Week 4, Week 8, Week 12
Change from baseline fasting serum leptin level at several timepoints within 3 months
Measured using ELISA method (Linco Research, USA). The limit of detection was 0.5 ng/mL, and the intra- and interassay coefficients of variation were 7% and 9%, respectively.
Week 0, Week 4, Week 8, Week 12
Change from baseline fasting serum lipid level at several timepoints within 3 months
Fasting total cholesterol, high density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL) and triglyceride (TG) concentrations will be measured.
Week 0, Week 4, Week 8, Week 12
Change from baseline immunological markers at several timepoints within 3 months
The fasting plasma CRP level will be assessed using an high-sensitivity CRP ELISA kit (Bender MedSystems, USA), for which the limit of detection was 3 pg/mL and the intra- and inter-assay coefficients of variation were 6.9% and 13.1%, respectively. The other immunological parameters to be analyzed include TNF-α, TGF-β1, IL-1, IL-8 and IL-10.
Week 0, Week 2, Week 3, Week 4, Week 8, Week 12
Change from baseline neurocognitive performance at 3 months
Neurocognitive performance will be assessed using Continuous Performance Test (CPT), Finger-Tapping Test (FTT) and Wisconsin Card-Sorting Test (WCST).
Week 0, Week 12
Change from baseline social cognitive function at 3 months
Mayer-Salovey-Caruso emotional Intelligent Test (MSCEIT): four branches: perceiving emotion (consisting of two tasks: face and picture tasks), facilitating emotion, understanding emotion, and managing emotion (Mayer, Salovey, Caruso, \& Sitarenios, 2003). The results will be scaled to a standard score based on the weight from the representative adult population (regarding age, gender, and ethnicity) in an extremely large sample of people (5,000). The reliability and validity of MSCEIT V2.0 have been proved before.
Week 0, Week 12
Change from baseline autonomic nervous system performance at several timepoints within 3 months
Cardiac autonomic function will be calculated by the geometric method, which is based on short-term measurements of the interbeat interval (IBI) \[82\]. Power spectral density analysis of HRV will be performed by fast Fourier transformation \[83\].
Week 0, Week 4, Week 12
