Study Arms:
- Major Depressive Disorder Population (Type: EXPERIMENTAL): 100 Individuals with DSM-5-defined MDD, aged 18-65~All participants receiving vortioxetine for a total of 8 weeks. Participants will receive10 mg/day on days 1-14 of the study treatment period, with the option to increase to vortioxetine 20 mg/day at the end of Week 2 based on physician's judgment. For the remaining 6 weeks, the dose of vortioxetine will be flexible at 10 or 20 mg/day as decided by a research doctor.~Patients will receive the THINC-it over 3 time frame periods. The THINC-it comprised of: Spotter, Symbol Check, Codebreaker, Trails, and PDQ-5-D.
- Healthy Control Population (Type: OTHER): 50 Healthy Controls (18-65 years of age) matched on sex, age, and years of education
