Study Arms:
- neurofeedback augmentation group (Type: EXPERIMENTAL): The neurofeedback augmentation group was asked to participate in 12 weeks of combined therapy of medication and 12-24 sessions of neurofeedback training. The neurofeedback protocol was determined considering the patient's main symptoms. Patients in the neurofeedback augmentation group received sensorimotor rhythm (SMR) beta or beta training for 30 minutes, and then alpha/theta (A/T) training for 30 minutes in each session.
- medication-only (treatment as usual, TAU) group (Type: ACTIVE_COMPARATOR): To reduce the impact of confounding factors, the medication-only (treatment as usual, TAU) group visited at the same schedule as neurofeedback augmentation group and received psychotherapy placebo sessions instead of neurofeedback training sessions. These sessions included psychological assessment and supportive psychotherapy. The medication-only (treatment as usual, TAU) group maintained the same medication use as that before the study.
- healthy controls (Type: NO_INTERVENTION): The healthy controls provided blood samples using the same procedure at baseline only.
