Repetitive Transcranial Magnetic Stimulation(rTMS) in the Treatment of Depression

This study is currently recruiting participants. (see Contacts and Locations)

The objective of this study is to investigate the antidepressant efficacy of rTMS, and to assess cortical metabolism before and after rTMS sessions in patients with major depression. We also aimed to investigate differences between the responders and nonresponders to rTMS and what would predict clinical response to rTMS.

Condition Intervention
Major Depressive Disorder
Device: repetitive Transcranial Magnetic Stimulation

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Repetitive Transcranial Magnetic Stimulation(rTMS) in the Treatment of Depression : Effect of TMS on Depression, Cognitive Function, and Regional Cerebral Glucose Metabolism

    measuring instrument of severity of depressive symptoms

Biospecimen Retention:   Samples With DNA
serum, plasma and DNAs

Estimated Enrollment: 40
Study Start Date: February 2006
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
repetitive Transcranial Magnetic Stimulation
repetitive Transcranial Magnetic Stimulation is a depressive patient group treated with rTMS
Device: repetitive Transcranial Magnetic Stimulation
10 times repetitive TMS, high frequency

Detailed Description:
The specific aims of this study is to: (1) evaluate the antidepressant efficacy of rTMS on major depression; (2) evaluate the effects of rTMS on cognitive function in depressive patients; (3) assess the effects of rTMS on cerebral glucose metabolism in depressive patients as measured by 18FDG PET; (4) investigate the differences of the regional cerebral glucose uptake changes during rTMS between responders and nonresponders to rTMS.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients with major depressive disorder, who were not responsive to antidepressants

Inclusion Criteria:

  • Twenty patients fulfilling the diagnostic criteria of major depression according to DSM IV will be enrolled in the study.
  • Antidepressant medication will be maintained throughout the study period.

Exclusion Criteria:

  • Exclusion criteria are current neurological or other psychiatric disorders, as well as a history of epileptic seizures, substantial brain damage or neurosurgical operation, according to established safety criteria.
  • To exclude the effect of drug changes on post-rTMS cerebral glucose metabolism, the combinations and dosage of pre-rTMS antidepressant drugs will remain unchanged until the post-rTMS 18FDG PET is done.
