Background: ECT is an effective treatment indicated for patients with treatment resistant depression. Although most patients display some degree of recovery, 32-52% do not respond or remit at all. Considering the possible side effects and the considerably high cost of treatment, it is important to identify sub-populations that would benefit the most from ECT. In the current study we sought to identify predictive molecular markers in the blood of depressed patients who are responsive to ECT. Methods: Patients, ages 18-70, with the diagnosis of treatment-resistant depression will be recruited. Participants will undergo psychiatric and psychological assessments, before (baseline) and 12 weeks after ECT initiation. Assessments will include the Montgomery-Asberg Depression Rating Scale (MADRAS), Clinical Global Improvement and Severity Scales (CGI-S, CGI-I), Inventory of Depressive Symptomatology (IDS), and the State-Trait Anxiety Inventory (STAI). Blood samples for serum and isolation of peripheral blood mononuclear cells (PBMCs)will be collected at baseline and the 12-week end-of-treatment time points for molecular analysis.
