Changes of Functional Connectivity After rTMS in Depression
|Major Depression||Device: repetitive transcranial magnetic stimulation(rTMS) Device: Sham repetitive transcranial magnetic stimulation(rTMS)||Phase 4|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Participant)
Primary Purpose: Treatment
|Official Title:||Change of Dopamine Pathway After rTMS Treatment in Major Depressive Disorder|
- change of functional connectivity between pre/post rTMS [ Time Frame: 14 days ]
|Study Start Date:||May 2009|
|Study Completion Date:||June 2011|
|Primary Completion Date:||June 2011 (Final data collection date for primary outcome measure)|
|Experimental: transcranial magnetic stimluation||
Device: repetitive transcranial magnetic stimulation(rTMS)
10-day course of 10 Hz rTMS on left dorsolateral prefrontal cortex of the subjects.
Other Name: MAGSTIM
|Sham Comparator: rTMS_sham||
Device: Sham repetitive transcranial magnetic stimulation(rTMS)
Sham repetitive transcranial magnetic stimulation(rTMS)
Up to now, 24 patients with major depression and 6 normal controls are enrolled. Twenty-three patients and 4 normal participants have taken 10 days rTMS. One patients and one control withdrew their consent without any reason and one control withdrew the consent because of headache.
We scanned fMRIs(to examine functional connectivity)twice for each participant, which were taken 3 days before the first and 3 days after the last rTMS.
All of participants have not reported side effects except mild headahe. There's been no seizure event up to now.
