The study will be a prospective, single arm trial in which a set of patients who will be treated for major depression using Repetitive Transcranial Magnetic Stimulation (according to FDA approved rTMS standard care practices) also will undergo EEG recording before Repetitive Transcranial Magnetic Stimulation treatment begins, and at the completion of treatment. The Hamilton Depression Rating Scale will be given to participants by the neuropsychiatrist at baseline and weekly intervals till the completion of treatment.~The neuropsychiatrist investigators expect to see about 12 patients per year who meet treatment criteria for Repetitive Transcranial Magnetic Stimulation. Therefore, it is expected to recruit 24 subjects into the research study over a two-year period.
Repetitive Transcranial Magnetic Stimulation (rTMS) is a promising, novel, non-invasive therapy for depression. The study is looking at changes in specific electroencephalogram parameters in depressed patients treated with rTMS can serve as predictors of depression treatment response among cancer patents undergoing rTMS treatment of depression.
