Transcranial Magnetic Stimulation in Major Depression With EEG and Near Infrared Spectroscopy (NIRS) Monitoring

Depression Clinical Trial

Official title: Transcranial Magnetic Stimulation in Major Depression With EEG and NIRS Monitoring

Status Terminated

Clinical Trial Summary

This a 12- week study (1-4 week screening, 6 weeks treatment, 2 weeks follow-up) outpatient open label clinical trial. Twenty-five subjects diagnosed with depression with a Montgomery Asberg Depression Rating Scale (MADRAS) score of 26 or higher, will be enrolled into this trial, up to fifty subjects will be consented. The primary purpose of the current study is to determine: 1) if changes in electrical activity of the brain measured by EEG in specific areas is associated with changes in the blood flow of the brain 2) Which areas of the brain show changes in electrical activity and treatment response.

Clinical Trial Description

Transcranial magnetic stimulation (TMS) has demonstrated efficacy as a treatment for major depression. No objective markers have been identified that indicate which patients are most likely to respond to TMS therapy. The goal of the present investigation is to determine whether an electroencephalographic measure called cordance or a measure of blood flow in the frontal brain, as measured by near infrared spectroscopy (NIRS) can serve as predictors of outcome with TMS therapy in depression. Subjects with depression will be treated in this study for 6 weeks with TMS. Frontal brain blood flow measured using NIRS will be assessed prior to TMS therapy, and repeatedly thereafter. EEG cordance will also be obtained following a similar schedule. Measures of depression and other psychiatric disorders will be collected prior to, during and for 2 weeks after the completion of TMS treatment. The correlation between these measures and the EEG and NIRS measures will then be determined to see if these latter measures are predictive of improvement in depression. ;
