Filter by:Background: Mindfulness has its origins in an Eastern Buddhist tradition that is over 2500 years old and can be defined as a specific form of attention that is non-judgemental, purposeful, and focused on the present moment. It has been well established in cognitive behavior therapy in the last decades, while it has been investigated in manualized group settings. Consequently, the demand to investigate mindfulness under effectiveness conditions in trainee therapists has been highlighted. Methods/Design: To fill in this research gap, the investigators designed the PrOMET-Study. In this study, the investigators will analyze the effects of brief, audio-tape presented, in-session mindfulness interventions conducted by both trainee therapists and their patients at the beginning of individual therapy sessions in a randomized, controlled longitudinal design under effectiveness conditions in a total of 30 trainee therapists and 150 patients in a large outpatient training center. The investigators hypothesize the mindfulness intervention will have positive effects on therapeutic processes and outcome in contrast to a progressive muscle relaxation and a treatment as usual group. The investigators will conduct multilevel modeling to address the nested data structure. Discussion: The study results could provide important practical implications, as they could inform ideas on how to improve clinical training of psychotherapists that could be implemented very, as there is no need for complex infrastructures or additional time concerning these brief, in-session mindfulness interventions that are directly implemented in treatment sessions.
The investigators will be looking at MAO-A density before and after seven weeks of treatment with an antidepressant and dietary supplement. MAO-A is an enzyme that breaks down brain chemicals that regulate mood. MAO-A density is elevated in patients with major depressive episodes (MDE) secondary to major depressive disorder (MDD). Many remain treatment resistant with common antidepressant treatments and we think it may be due to poor targeting of brain pathologies. We want to test if adding a dietary supplement may normalize MAO-A.
This 8-week, pilot randomized, controlled trial to evaluate the benefits of transdiagnostic Internet-based CBT (iCBT) in young adults with MDD, SAD, PD or GAD. The investigators hypothesize that patients who receive iCBT will show significant improvement in anxiety symptoms and functioning, compared to a wait-list group. This pilot randomized controlled study will assess the efficacy of transdiagnostic iCBT in 60 young adults.
The Investigators are conducting a research study to learn about the safety and benefit of using a medication called buprenorphine for patient with difficult to treat depression . This research study is testing whether combining two medications will be effective in treating depression when initial treatment with just one antidepressant does not relieve the depressive symptoms ; this is what is called " difficult to treat depression " or " treatment resistant depression ". The two medication the investigators are using are " an anti-depressant medication called venlafaxine XR ( the generic form of Effexor ) and buprenorphine . Buprenorphine is a medication that is FDA approved for the treatment of opioid dependence. The investigators are testing whether adding buprenorphine to venlafaxine enhances treatment response.
The purpose of this study is to investigate the effects of a computerized cognitive training program (an attention and memory exercise performed on a computer) on thinking and memory in individuals with mood and anxiety disorders, and to begin to test whether this training affects symptoms of depression or anxiety.
The investigators propose to examine both resting state activity and functional activity during rumination and during self-processing to study the relationship between neural correlates of rumination/self-focus and self-processing in major depression and bipolar disorder.
The purpose of this study was to investigate the efficacy of duloxetine versus placebo on pain in outpatients with major depressive disorder (MDD): change in Brief Pain Inventory Short Form (BPI-SF) 24-hour average pain score from baseline over the 8 weeks of treatment
Objective: Metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors that respond to glutamate by activating proteins inside nerve cells that affect cell metabolism, thereby fine-tuning the signals sent between cells to maintain balance in neuronal activity. mGluR subtype 1 (mGluR1s) are located in several brain regions, including the cerebellum, hippocampus, olfactory bulb, and basal ganglia. mGluR1 activation stimulates phospholipase C, resulting in phosphoinositide hydrolysis and increased intracellular calcium levels. Successful development of a positron emission tomography (PET) ligand to image mGlurR1 would impact clinical management of brain disorders characterized by disruptions in glutamatergic transmission, including anxiety and stress disorders, drug addiction, epilepsy, Huntington s disease, and Parkinson s disease. However, detailed study of mGluR1s has heretofore been hindered by the lack of high affinity and selective ligands for this receptor subtype. The present protocol will evaluate the ability of a new PET ligand, [18F]FIMX, to image and quantify mGluR1 in the brain of healthy human volunteers. This protocol covers four phases: 1. Phase 0: screening whole-body scan; 2. Phase 1: kinetic brain imaging to quantify mGluR1 in brain relative to concurrent measurement of the parent radioligand in arterial plasma; 3. Phase 2: if the tracer is successful in Phase 1, we will estimate radiation-absorbed doses of [18F]FIMX by performing whole body imaging; 4. Phase 3: test-retest analysis of brain binding relative to concurrent measurement of the parent radioligand in arterial plasma. Study Population: Healthy adult female and male volunteers (n=22, ages 18 to 55) will undergo brain or whole-body imaging.. Design: This study will begin with a screening whole-body scan to confirm that the radioactivity has fairly broad distribution in several organs. For absolute quantification of mGluR1, 22 healthy controls will have brain PET imaging using [18F]FIMX and an arterial line. Up to 12 of them will have a test-retest scan. Eight additional subjects will have a whole body PET scan for dosimetry, which does not require an arterial line. <TAB> Outcome Measures To assess absolute quantitation of mGluR1 with [18F]FIMX, we will primarily use two outcome measures: the identifiability and time stability of distribution volume calculated with compartmental modeling. In test-retest study, we will calculate the retest variability. To assess whole-body biodistribution and dosimetry of [18F]FIMX we will use the organ time-activity curves....
Study to assess efficacy of Duloxetine 120 mg and Duloxetine 60 mg in patients hospitalized for severe depression after 4 weeks of treatment. To evaluate the rescue option in non-responding patients. Safety of Duloxetine will also be assessed.
This is a pilot study divided into two phases. IN phase 1 (completed) participants will be randomized to receive 8 weeks of Problem Solving Therapy (PST) alone or 8 weeks of a cognitive training game called, Evolution (Evo) plus clinical management. In Phase 2 (now recruiting), participants will be randomized to Evo, PST, and a different cognitive training program called Words. Words is similar to Evo in that it is an adaptive training program and includes case management. IN both studies participants will be assessed for clinical and functional magnetic resonance imaging (fMRI) outcomes at baseline, 4 weeks and 8 weeks.
