Details and patient eligibility

About

The investigators aim to investigate whether the intervention effect of pBFS-guided rTMS therapy targeting DLPFC is superior to the intervention effect of the traditional "5 cm-rule" guided rTMS therapy in patients with depressive disorders.

Full description

After being informed about the study and potential risks. All patients giving written informed consent will undergo a screening period to determine eligibility for study entry. At week 0, patients who meet the eligibility requirements will be randomized in a blind manner in a 1:1 ratio to the pBFS group, or 5-cm rule group. Then all participants will undergo a 21-day rTMS modulation and 7-day, 14-day, and 45-day post-treatment follow-up visits. Participants will not take any other treatment during the intervention and the 7-day and 14-day post-treatment visits.

Enrollment: 150 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
