Filter by:Aripiprazole has been approved by the FDA for augmenting ineffective/partially effective oral antidepressant therapy in patients suffering from major depression. The mechanism by which this augmentation is achieved is not known. This study has been designed to test the hypothesis that the primary mechanism of action of aripiprazole (ARP) antidepressant augmentation is through the dopaminergic pathway. Two positron emission tomography (PET) scan procedures and a functional magnetic resonance imaging (fMRI) scan will be used to test this hypothesis.
The main purpose of this study is to evaluate the effect of desvenlafaxine administered as DVS SR on the pharmacokinetics of midazolam in healthy male and female subjects. The amount of drug in the body and the effect of the drug will also be evaluated.
Research aimed at assessing changes in depressogenic thinking and the ability to disengage from depressogenic thinking following Mindfulness-Based Cognitive Therapy
The study involves a 32-week randomized controlled trial in primary care of a comprehensive diabetic and depression intervention in patients with type 2 diabetes and comorbid MDD, compared to a group treated with usual care for MDD plus disease self-management and measurement-based care for diabetes.
The purpose of this study is to study the effect of duloxetine treatment on (1) cognitive functions, the brain mechanisms involved with thinking, reasoning, learning, and remembering; (2) psychosocial functions, how someone interacts with his/her social environment; and (3) the relationship between these two functions, in people who have major depressive disorder, a severe form of depression.
The purpose of this study is to examine whether the speed of the clinical antidepressant action of citalopram can be accelerated by administering double doses of pindolol (15 mg/day, tid) which presumably should lead to increased 5-HT1A autoreceptor occupancy.
The purpose of the study is to evaluate the efficacy and safety of deep brain rTMS, (Transcranial Magnetic Stimulation), a new experimental procedure using the H-Coil, in subjects with Major Depressive Disorder that have been previously unsuccessfully treated with antidepressant medications.
Representative payees, mostly family members, manage Social Security Administration funds of more than one million people with psychiatric disabilities. Although studies show payeeship can be used coercively, foster dependency, reduce work incentives, lead to family conflict and even violence, there has been little systematic research on how to lower these significant barriers to community integration. The investigators' long term goal is to promote recovery among adults with psychiatric disabilities who have payees by reducing downsides associated with what has been called "the nation's largest guardianship system." The investigators' objective in the current application is to evaluate a pilot-tested, stakeholder-informed intervention that is grounded in principles of psychiatric rehabilitation and encourages consumers with psychiatric disabilities and their family members to collaborate within the representative payee arrangement.
The primary goal of the pilot is to test the feasibility and utility of using a text-messaging system to engage adolescents in improved homework adherence during cognitive-behavioral therapy (CBT) for major depressive disorder.
Do functional brain changes occur during Venlafaxine ER (extended release) versus Fluoxetine treatment and do changes in selective structures, such as the amygdala, predict treatment response?
