Study Arms:
- Intervention Cohort (Type: EXPERIMENTAL): Patients will undergo baseline psychological and laboratory tests then receive Quetiapine-XR(Seroquel-XR) with flexible dosing at the discretion of the treating physician based on clinical response and tolerability. The dose range will be from 50-300mg. The total duration of the treatment will be 12 weeks.
- Healthy Control (Type: NO_INTERVENTION): Participants without major depressive disorder or anxiety are enrolled as a comparison group without intervention.
