Filter by: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.
Objective: To study the relative balance of GABA (A) binding potential and glutamate utilization in subjects with localization-related epilepsy with and without depression, subjects with major depressive disorder alone, and in subjects with generalized epilepsy (expected not to have significant comorbid depression). Pilot data shows that GABA(A) binding potential and glutamate utilization are tightly coupled in healthy subjects particularly in the mesial temporal lobe. We hypothesize that subjects with epilepsy will not exhibit the same degree of coupling, and that subjects with both epilepsy and depression will exhibit an even more pronounced decoupling. Study Population: Subjects aged 18-55 with localization-related epilepsy with and without depression, subjects with generalized epilepsy, subjects with major depressive disorder (MDD) alone, and healthy controls. Design: This is a neuroimaging study, using positron emission tomography (PET) with [11C]flumazenil, to measure GABA(A) binding potential, and [18F]fluorodeoxyglucose, to measure glucose utilization (reflective of neuronal glutamate release) Magnetic resonance spectroscopy (MRS), will be used to measure GABA and glutamate in the mesial temporal cortex, and corroborate the PET results. Structural magnetic resonance images (MRI) will be obtained for MRS localization and partial volume correction of PET images. Outcome measures: The binding potential of GABA(A), the regional rate of glucose metabolism, and the levels of GABA and glutamate as measured by MRS. Patients will be stratified by seizure type and depression ratings. ...
This study will examine the feasibility and efficacy of a personalized psychotherapy treatment for people with depression and co-occurring anxiety.
The purpose of this study is to investigate the (cost)effectiveness of mindfulness based cognitive therapy (MBCT) compared to that of antidepressant medication, and its combination with regard to the prevention of relapse or recurrence in patients with recurrent depression.
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.
This study will examine differences in activity of the anterior cingulate cortex, a brain area involved in emotion and cognitive regulation, between older adults with and without depression.
The purpose of the study is to compare the sedation profile one hour after dose administration between Seroquel IR and Seroquel XR.
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.
This study will examine whether measures of brain electrical signals taken after a week of antidepressant medication treatment can predict whether a full treatment regimen will be effective.
