Is Vitamin D Insufficiency and Deficiency Associated With Antepartum and Postpartum Depression?...
DepressionPostpartum DepressionOur primary aim is to evaluate whether Vitamin D deficiency causes depressive symptoms in antepartum and postpartum depression and whether early correction of Vitamin D deficiency improves these symptoms. Our secondary aims evaluate maternal and fetal outcomes including antepartum, intrapartum, and immediate postpartum complications. We are also evaluating the effectiveness of a common vitamin D treatment regimen used outside of pregnancy.

tDCS in Parkinson's Disease With Depression
DepressionParkinson'sParkinson's disease (PD) is a progressive neurological disease that has effects on both movement and mental health. One of the most common mental health complications of PD is depression. Up to 30% of Parkinson's patients will experience depression at some point. We aim to investigate whether transcranial direct current stimulation (tDCS), a type of electrical stimulation for the brain, can improve depression in PD as well as improve motor function in PD.

The Effect of Melatonin on Depression, Anxiety, Cognitive Function and Sleep Disturbances in Breast...
Breast CancerDepressionThe purpose of this study is to investigate the effect of 6 mg melatonin daily for 1 week preoperatively to 12 weeks postoperatively on depressive symptoms, anxiety, cognitive function and sleep disturbances in breast cancer patients. Furthermore the investigators will examine whether a specific clock-gene (HPER3) is correlated with an increased risk of depression, sleep disturbances or cognitive dysfunction.

Can Magnetic Brain Stimulation Help Prevent Relapse in Depression?
Major Depressive DisorderThe purpose of this study is to investigate the use of repetitive transcranial magnetic stimulation (rTMS) in helping to prevent relapse in major depressive disorder. rTMS is known to be an effective treatment for major depressive disorder, but there is also evidence that it may be effective in the maintenance of remission following treatment. However, it is not yet clear what maintenance strategy will yield the best outcome in preventing relapse. In this study, eligible patients who have finished one full course of rTMS for treatment of major depression will be randomized into three groups: (i) cluster rTMS, (ii) taper rTMS, and (iii) treatment as usual. The 'cluster rTMS' group will receive two weeks to daily rTMS six months after the completion of their regular rTMS treatment, the 'taper rTMS' group will receive three sessions a week for two weeks followed by two sessions a week for two weeks immediately following their regular rTMS treatment, while the 'treatment as usual' group will receive standard follow-up care from their own psychiatrist and/or primary care doctor. The investigators hypothesize that the group with cluster treatment will show significantly lower relapse rates in depressive symptoms as compared to the other groups.

Dyadic Therapy for Mothers and Children
DepressionBehavioral ProblemsThis study compares the effectiveness of Child Parent Psychotherapy to that of usual care (defined as: referral to therapists in the community or Columbia University Medical Center) in improving maternal depressive symptoms and child emotional and behavioral disturbances. The investigators will recruit mothers who report being mildly to moderately depressed and their preschoolers (ages 3-5 years) who they are concerned are exhibiting emotional and/or behavioral problems.
