Overview
Brief Summary
This study is designed to test whether low-field magnetic stimulation (LFMS) can relieve some of the symptoms of depression in bipolar disorder or major depression.
Detailed Description
This study involves a screening visit with the study physician and a treatment visit. Participants will be asked to complete several questionnaires about their mood during both visits. The treatment visit will involve use of the LFMS device. Participants will place the top of their head inside the device for approximately 20 minutes. Participants will receive either the actual treatment or a sham treatment and will not know which they receive. This device produces weak electromagnetic fields. There is no discomfort or even sensation caused by the device. The device has been declared to be a "non-significant risk device" by the FDA, and there are no known risks associated with its use.

Outcomes
Primary Outcomes
Mean Change in Hamilton Depression Rating Scale (HAM-D) (17 Item) in Subjects With Bipolar Depression
Time Frame: Once just before and once just after treatment
A multiple choice questionnaire used to rate depression severity. Mean change from pretreatment score. 17 items reflecting depression symptoms are scored on scale of severity; 9 items are scored 0 = Absent 1 = Trivial 2 = Mild 3 = Moderate 4 = Severe 8 items are scored 0 = Absent 1 = Mild 2 = Severe. Items are summed; minimum score is 0, maximum score is 52. Higher scores represent more severe depression.

Visual Analog Scale (VAS) in Subjects With Bipolar Depression
Time Frame: Once just before and once just after treatment
Eleven point Likert scales indicating immediate depression state. Mean change from pretreatment score. Participant marks an 'X' on a numbered line anchored by 0 = no depression and 10 = most depressed ever been.
Visual Analog Scale (VAS) in Subjects With Major Depressive Disorder
Time Frame: Once just before and once just after treatment
Eleven point Likert scales indicating immediate depression state. Mean change from pretreatment score. Participant marks an 'X' on a numbered line anchored by 0 = no depression and 10 = most depressed ever been.
