Study of Repetitive Transcranial Magnetic Stimulation (rTMS) in Depressed Teens

April 20, 2016 updated by: Paul E. Croarkin

An Open-Label Eight-Week Trial of Repetitive Transcranial Magnetic Stimulation in Depressed Adolescents: Mechanisms of Response

This research study aims to test the safety and effectiveness of repetitive transcranial magnetic stimulation (rTMS) on teens with depression. The study also seeks to understand how rTMS treatment affects the neurobiology of teens with depression.

Study Overview

Status

Completed

Detailed Description

This study aims to:

  1. Evaluate the antidepressant effect and safety of rTMS in adolescents meeting criteria for major depressive disorder, single or recurrent episode.
  2. Evaluate, by proton magnetic resonance spectroscopy (1H-MRS) at 3 Tesla (3T), the regional specificity [anterior cingulate (AC) vs. left dorsolateral prefrontal cortex (L-DLPFC)] of cerebral metabolites (glutamate and glutamine) in adolescent depression and study whether glutamine resonances are associated with response or remission of clinical depressive symptoms when rTMS is used to treat adolescent depression.
  3. Evaluate the accuracy of an efficient method for locating the F3 position (i.e., L-DLPFC) through comparison with magnetic resonance imaging (MRI).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Children's Depression Rating Scale-Revised (CDRS-R) Post Treatment 30 or Last Treatment (in Cases of Early Withdrawal)
Time Frame: 5 days of Treatment 30 or Last Treatment
The Children's Depression Rating Scale-Revised (CDRS-R) is a validated, 17-item, semi-structured clinician rating tool to assess severity of depression with subject and parental input for 14 of the 17 items.
5 days of Treatment 30 or Last Treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical Global Impression - Severity (CGI-S) Post Treatment 30 or Last Treatment (in Cases of Early Withdrawal)
Time Frame: Within 5 days of Treatment 30 or Last Treatment
The Clinical Global Impression - Severity (CGI-S) is a standardized assessment utilizing a 7-point scale with which the clinician rates severity of the subject's depressive illness at the time of assessment relative to the clinician's past experience with patients with the same diagnosis. Range of scale is 1-7 (1= normal, not ill at all; 7= among the most ill patients; larger number indicates greater severity of symptoms or worse outcome).
Within 5 days of Treatment 30 or Last Treatment
The Clinical Global Impression - Improvement (CGI-I)
Time Frame: Within 5 days of 30 treatments or after last treatment in case of early withdrawal
The Clinical Global Impression - Improvement (CGI-I) is a standardized assessment utilizing a 7-point scale with which the clinician rates improvment of the subject's depressive illness at the time of assessment relative to the clinician's past experience with patients with the same diagnosis. Range of scale is 1-7 (1= very much improved, 7=very much worse) larger number indicates greater severity of symptoms or worse outcome).
Within 5 days of 30 treatments or after last treatment in case of early withdrawal
