Brief Summary:
The objective of this investigation is to examine the safety and feasibility of a series of repetitive transcranial magnetic stimulation (rTMS) treatments (10 Hertz [Hz]; Left Dorsolateral Prefrontal Cortex), with a Neuronetics Model 2100 Therapy System as adjuvant treatment for depression in adolescent subjects.

Condition or disease Intervention/treatment Phase
Depression Device: rTMS Treatment Not Applicable

Detailed Description:
High frequency rTMS applied to the left dorsolateral prefrontal cortex (L-DLPFC) has been shown to have an antidepressant effect. Initial studies comparing electroconvulsive therapy (ECT) and rTMS suggest that rTMS has been as effective as ECT in treating non-psychotic depression. Given the high degree of ongoing dysfunction in depressed adolescents despite optimization of treatment with antidepressant medications, new concerns regarding suicidal thoughts and behaviors in adolescents treated with antidepressant medications, and the more interventional nature of ECT, the use of rTMS as adjuvant therapy may be of significant clinical benefit. Thus far, research using rTMS to treat depression in adolescents has been limited. The primary aim of this study is to examine the safety and feasibility of using 10 Hz rTMS applied to the left dorsolateral prefrontal cortex (L-DLPFC) as adjuvant treatment for depression in adolescents.

Primary Outcome Measures :
  1. Change in Cognitive Status as Measured by the Children's Auditory Verbal Learning Test 2 (CAVLT-2) [ Time Frame: Pre-treatment (baseline visit) and post treatment (approximately 6-8 weeks after baseline visit) ]
    The Children's Auditory Verbal Learning Test 2 (CAVLT-2) is a neuropsychological test that measures auditory verbal learning and memory. This test is designed for ages 6.6-17.11 years. Scores are reported as normalized standard scores. The minimum standard score is 60 and the maximum 140; a higher score indicates a better performance.

Secondary Outcome Measures :
  1. Mean Level of Depression at Visit 30, as Measured by the Children's Depression Rating Scale, Revised (CDRS-R) [ Time Frame: At study visit 30 ]
    The Children's Depression Rating Scale, Revised (CDRS-R) is a validated, 17-item, clinician rating tool to assess severity of depression. Parents provide input into 14 of the items. Scores range from 0 to 60, with the following scale: not depressed (<20), borderline depressive symptoms (20-29), mild depression (30-39), moderate depression (40-59), severe depression (>/=60).
