Filter by:The purpose of this study is to see how an insulin sensitizing medication, Pioglitazone, can cause changes in mood in some depressed patients. Study participants receive assessment of their cognitive and metabolic functioning. If they meet criteria, they will be asked to take either Pioglitazone or a placebo for a 90-day trial. Participants will undergo an Oral Glucose Tolerance Test to measure fasting insulin and glucose levels, as well as routine blood testing. The investigators hope to quantify the role of Pioglitazone in patients with mood disorders and compare the values to those previously obtained in a healthy age-matched control population. The investigators also hope to examine the association between IR and cognitive performance and clinical course of depression in patients with mood disorders.
Depressed patients will be offered experimental treatment with a new, potentially fast-acting antidepressant called ketamine while being scanned by magnetic resonance imaging (MRI) to measure the chemical effect of the drug. Ketamine will be given in a dose of 0.0 (placebo), 0.1, 0.2, 0.3, 0.4, or 0.5 mg/kg. If a patient does not respond to ketamine after the first infusion, it may be because s/he received ketamine placebo or the dose of ketamine was too low. In that case, an optional second scan and infusion of active ketamine (0.5 mg/kg) will be offered. This second scan will occur no later than weeks after the first scan/infusion (as scheduling permits). There is no guarantee that the patient will respond to the second ketamine infusion. Patients enrolled in the study are eligible for up to 6 months treatment with their study psychiatrist after the ketamine infusion(s). Healthy Volunteers: Healthy controls will receive an infusion of ketamine at a single dose (0.5 mg/kg). Volunteers will only receive one MRI scan and infusion.
Primarily, this study seeks to evaluate whether citalopram treatment is associated with an increase in the Glutamine (Gln)/Glutamate (Glu) ratio in the anterior cingulate cortex (ACC) from baseline to day 3 of treatment. Additionally, this study would like to examine whether citalopram treatment is associated with an increase in the Gln/Glu ratio in the ACC from baseline to day 7 of treatment.
The objective of this study is to evaluate the effectiveness of ketamine (infusion of 0.5mg/kg) and venlafaxine compared to the use of venlafaxine alone in the treatment of major depression (MADRS score ≥ 20 ) to six weeks of treatment.
The Institute of Medicine identifies Prolonged Grief (PG) as a critical under-addressed public health problem for which are no empirically supported treatments. The purpose of this application is to pilot-test Behavioral Activation (BA) therapy for PG. BA is a well supported, stand alone intervention for depression and recently applied to posttraumatic stress disorder, which reduces rumination and avoidance behaviors that otherwise thwart access to natural rewarding contingencies and resources. The treatment focuses on promoting stable, active routines, self-care behaviors, enhanced self-efficacy, and reengagement with pleasurable activities and significant social resources. Rumination, disengagement, and low self-efficacy are defining features of PG. Further, in response to loss of intimates, the key factors that differentiate resilient people from those that have difficulties adapting is the maintenance or fast resumption of social and occupational functioning. Thus, the main hypothesis of this study is that BA for PG will result in clinically significant reductions in rumination and functional disengagement. This is a preliminary small-scale pilot assessment of potential efficacy and feasibility of completing a large scale study of BA for PG.
The purpose of this study is to determine the efficacy of a brief psychological intervention focused on the personal dilemmas identified for each depressive patient. For that, this intervention is combined to group cognitive therapy (an already proven efficacious format) and compared to cognitive individual therapy.
The current study is being conducted in patients with major depression. The study aims to 1) investigate the combined effects of selective serotonin reuptake inhibitor (SSRI) and bupropion compared to SSRI alone on the improvements of depressive symptoms, fatigue, hypersomnia, and neurocognitive functions, 2) observe structural/functional/chemical changes using magnetic resonance imaging (MRI), 3) and examine a relationship between the improvements of depressive symptoms, fatigue, and hypersomnia and the neural changes.
The purpose of this study is to see if using Transcranial LED Therapy (TLT) using the PhotoMedex's Omnilux NEw-U LED helps improve symptoms of major depressive disorder (MDD). TLT works by briefly delivering near-infrared (non-visible) radiations to the forehead. The radiations penetrate the brain and stimulate the cells & metabolism. Our goals are - To assess the antidepressant effect of the TLT in depressed subjects. - To assess the safety and tolerability of the TLT in depressed subjects - To assess the acceptability of the TLT in depressed subjects - To pilot test the impact on cognition of the TLT in depressed subjects (Ancillary Study)
The purpose of this study is to determine whether meditation will reduce stress and depressive of adult caregivers of a person with dementia.
The purpose of this study is to explore the effect of an inflammatory and a psychosocial stressor and the combination thereof on mood in healthy young and elderly participants and patients with Major Depressive Disorder (MDD).
