Beat the Blues in Pregnancy Study (TMS)
The purpose of this study is to determine if repetitive transcranial magnetic stimulation (TMS) will alleviate symptoms of major depressive disorder (MDD) in pregnant women.
TMS uses electromagnetic impulses to encourage neurons in the brain to communicate more effectively with one another. Effective neuron communication is thought to lead to the lessening of depressive symptoms. In this study subjects require daily TMS treatment for approximately four weeks.

- Hamilton Rating Scale for Depression (HDRS-17) [ Time Frame: Test Day 1, 10 & 20 ]We will be measuring changes in Hamilton Rating Scale for Depression (HDRS-17) scores from the beginning to end of treatment. The HDRS-17 will be administered on test day 1, 10, & 20.
- Brain Derived Neurotrophic Factor Increase with Active Transcranial Magnetic Simulation (TMS) [ Time Frame: Test Day 1 & 20 ]We will also be measuring levels of Brain Derived Neurotrophic Factor (BDNF), a protein thought to regulate mood and cognitive functioning. We will be obtaining BDNF values on test day 1 & 20. In addition, the relationship between BDNF and various hormones (estradiol, progesterone, allopregnanolone, oxytocin, and cortisol releasing hormone) will be examined.

Active Comparator: Active Transcranial Magnetic Stimulation
38 pregnant women with MDD will be randomized to receive active 1 Hz right-sided dorsolateral prefrontal cortex (DLPFC) TMS.
Device: Active Transcranial Magnetic Simulation
Subjects will be given active TMS 5 days per week for 4 weeks for a total of 20 sessions. Each session will last approximately 10 minutes.
Other Name: Neuronetics 2100 CRS TMS System
Sham Comparator: Sham Transcranial Magnetic Stimulation
38 pregnant women with MDD will be randomized to receive sham transcranial magnetic stimulation.
Device: Sham Transcranial Magnetic Stimulation
Subjects will be given sham TMS 5 days per week for 4 weeks for a total of 20 sessions. The sham coil contains a shielding mechanism which diverts the magnetic field away from the patient. The sham treatment will last approximately 10 minutes.
Other Name: The eSham System
We hypothesize that there will be a decline in the Hamilton Rating Scale for Depression (HDRS-17) scores from the beginning to end of treatment. We expect that this decrease will be significantly greater in subjects receiving active transcranial magnetic stimulation (TMS) compared to those receiving placebo TMS. Treatment response will be defined as greater than 50% reduction in HDRS-17 score.
We also hypothesize that levels of Brain Derived Neurotrophic Factor (BDNF), a protein thought to regulate mood and cognitive functioning, will increase in subjects who respond to TMS treatment. We expect BDNF levels to increase by greater than or equal to 20% in those who respond to TMS. As previously stated, TMS response will be defined as a significant decrease (50% or greater) in the HDRS-17 from baseline to end of treatment.
