The primary purpose is to compare with resting fMRI the functional networks of rest (RTS) in unipolar depression and in bipolar depression. Hypothesis : the main objective of this work is to compare with the rest fMRI the Rest Functional Networks (RFN) in the unipolar depression and in the bipolar depression in order to identify specific biomarkers for each affection. The general hypothesis of this work is that intra- and inter RFN connectivity is different between bipolar patients and unipolar patients. Specifically the investigators assume that connectivity within the default mode network (including ventral mediofrontal cortex, subgenual cingulate cortex, inferior parietal cortex, posterior cingulate cortex) will be increased in unipolar patients compared to bipolar patients.
Non emergent scheduled cesarean sections will be consented to participate in this study of patients who have screened negative for obstructive sleep apnea and who are also BMI>/= 35 to have capnography monitoring postoperatively. The capnography and pulse oximetry will be initiated in the post anesthesia care unit and be worn for 12-24 hours after delivery. Data will be retrieved after that time period in a deidentified fashion. Medication usage will be reviewed as well as the standard of care information from the duramorph monitoring will be retrieved.
For a number of reasons women with major depressive disorder often discontinue conventional antidepressants when they become pregnant and prefer not to take them when depressive illness develops in the course of pregnancy. There is now considerable evidence that the administration of the omega-3 polyunsaturated fatty acid, eicosapentaenoic acid (EPA), as monotherapy has antidepressant effects. If it could be clearly established as effective such an approach would offer a valuable alternative for woman who are at risk for, or who develop, depressive disorder during pregnancy. Strongly positive placebo-controlled trials of EPA supplementation, though, co-exist with entirely negative ones. No clear reasons for these discrepancies have emerged but one possibility is that the samples studied have differed in the proportion of individuals likely to benefit from EPA supplementation. As there has been no effort to identify such individuals we propose to explore two groups of measures, both relevant to EPA's likely mechanisms of action, as potential tools for identifying individuals likely to benefit this treatment. Hypothesis: Among women who experience major depressive episodes during their first two trimesters of pregnancy, baseline measures of cytokine activity and erythrocyte PUFA concentrations will be associated, in an additive or interactive fashion, with subsequent improvement in depressive symptoms among women taking omega-3 PUFA supplementation.
The purpose of this study is to determine if omega-3 polyunsaturated fatty acids as a monotherapy have antidepressant effects during pregnancy. It will also provide pilot data pertaining to relationships between apparent response to omega-3 monotherapy and both plasma cytokine and erythrocyte essential fatty acid concentrations.
The goal of this proposal is to conduct the first pilot study of whether consuming flavanol supplements will augment the cognitive and mood benefits of antidepressant medication in older adults with Late LifeDepression (LLD). Flavanols represent a specific group of plant derived nutrients that are found in cocoa beans, grapes, tea, berries and various other fruits and vegetables. The specific flavanols investigated in this study come from cocoa. Currently available treatments for LLD (i.e., antidepressant medication) are limited in efficacy, especially in individuals who also suffer from cognitive impairment. Recent studies performed at Columbia and elsewhere suggest that flavanols may induce beneficial brain changes that support cognitive functioning and elevate mood, but their precise clinical effects in older adults with combined depression and cognitive impairment remain to be evaluated. For this study, the investigators plan to recruit 50 adults aged ≥60 years who have Major Depressive Disorder, meet a minimum depressive symptom threshold despite currently receiving an adequate trial of an antidepressant, and have a significant cognitive complaints without a diagnosis of dementia. Subjects will be randomized to receive 8 weeks of augmentation treatment with flavanol capsules (in addition to continuing their antidepressant) vs. capsules not containing flavanols. Pre- and post-treatment MRI scanning of the brain will be conducted, and comprehensive pre- and post-treatment neuropsychological assessment will be performed. Results from this project will allow the investigators to evaluate a novel therapeutic approach to LLD, which could have large public health ramifications given the prevalence, frequent treatment resistance, and chronicity characteristic of LLD.
The purpose of this study is to help researchers learn about how the brain responds to rewards. This study is interested in seeing how these responses differ between people who are more and less responsive to insulin in their body, and people with and without depression.
The purpose of the study is to learn about the impact of exercise on fatigue, anxiety, and depression in Parkinson's disease. It is well established that exercise improves the motor symptoms of Parkinson's disease. However, it is not clear which types of exercise are most beneficial for specific non-motor symptoms.
The study aimed to determine the emotional reactivity of depressed patients to visual and olfactory stimuli in comparison with healthy volunteers.
The study aims to assess the therapeutic benefits of the adaptation of the antidepressant dose to the metabolic capacity (cytochrome P450 2D6) of elderly depressed patients. Therapeutic benefits are evaluated through the enhancement of efficiency, decrease of the action time and the after effects.
This pilot study aims to investigate whether a treatment called cranial electric stimulation or CES can decrease risk factors for suicide. The specific CES device we will use is called Alpha-Stim®. CES will be used in addition to usual treatment (medication and group therapy).
