Filter by:The aim of this project is to determine whether the acute oral administration of Ibuprofen changes the activation pattern in the amygdala and other brain structures during functional magnetic resonance imaging. The investigators use a double-blind, randomized, repeated-measures design. Each of the 20 healthy control subjects will be tested three times and receive placebo, 200 mg or 600 mg dose of ibuprofen p.o. The study will consist of 4 sessions: a baseline screening session and 3 testing sessions scheduled 1-2 weeks apart. Each of these individuals will undergo a multi-level assessment based on the RDoC approach that consists of (a) a standardized diagnostic assessment, (b) self-report questionnaires assessing the positive and negative valence domains as well as interoception, (c) behavioral tasks assessing reward-related processing, avoidance, and aversive processing, cognition, and interoception; (d) physiological measurements consisting of facial emotion expression monitoring, heart rate and respiration, (e) functional magnetic resonance imaging focusing on reward-related processing, fear conditioning and extinction, cognitive inhibition, and interoceptive processing, and (f) biomarker assessments.
This study will evaluate the effectiveness of intermittent Theta Burst Stimulation for patients with Major Depressive Disorder.
Individuals with affective disorders (including post-traumatic stress disorder (PTSD) and major depressive disorder (MDD)) often experience declines in cognitive abilities such as memory and attention. Such difficulties can reduce functioning in important aspects of life, including at work or school. Little research has been conducted to investigate if cognitive dysfunction can be reduced in individuals with PTSD or MDD following a specific treatment. Thus, the investigators plan to determine the utility of a cognitive training program called goal management training (GMT) in reducing cognitive dysfunction in MDD/PTSD. GMT aims to assist participants in building skills in performing specific behaviours that rely on basic cognitive processes, allowing them to achieve an identified goal. 64 individuals with PTSD and 64 with MDD will be divided into two groups of 32, one GMT group, and one wait-list group that will receive GMT after study completion. The investigators predict that in comparison to the wait-list group, the GMT group will show greater improvements in cognitive functioning and everyday functioning following treatment and that these improvements will remain long-term.
The purpose of this study is to validate the effectiveness of using an integrated mobile sensing platform to deliver large-scale data-driven interventions to patients with depression.
The purpose of this study is to evaluate the efficacy and safety and tolerability of JNJ-42165279 in participants with major depressive disorder (MDD) with anxiety symptoms who have had inadequate response to treatment with a selective serotonin reuptake inhibitor (SSRI) or serotonergic/noradrenergic reuptake inhibitor (SNRI).
The purpose of this study is to identify if there are self-reported or objective measures related to mood parameters that can predict near-term relapse (within 1 month or at another identified time point before meeting the criteria for relapse) or early symptomatic changes indicative of relapse prodrome in major depressive disorder (MDD).
Background: - Drugs and talk therapy help treat depression, but these treatments usually take quite a bit of time to work. Ketamine is a fast-acting antidepressant, but it has side effects like unusual dreams and experiences. The drug AV-101 may have the same antidepressant effects but fewer side effects. Researchers want to see if it is effective and safe for people with major depressive disorder. Objective: - To see if the drug, AV-101 is safe and if it treats symptoms of major depressive disorder. Eligibility: - Adults ages 18-65 with major depression without psychotic features. Design: - Participants will be screened under a separate protocol. - Participants will stay in the hospital for 12-14 weeks. - Phase 1 (2-7 weeks): participants will stop taking their medicines then not take any for 2 weeks. They will have several scans and other procedures. - Phase 2 (6-7 weeks): 2 weeks each of study drug and placebo once a day, with 2 weeks of no drugs in between. - Participants will have: - Physical exams - Interviews - Frequent blood collection. A needle will place a small plastic tube in the arm. Some blood samples will be taken through this tube. - 2 spinal taps (optional). The back will be numbed. A needle will insert a catheter between back bones. That will be left in for up to 30 hours. Spinal fluid will be collected through it. - 5 scans. Participants will lie in a machine with a magnetic field. The machine takes pictures of the brain and brain chemicals. - At the end of the study, participants will have medical evaluation, questions, and blood tests. Some may continue treatment at the clinic.
To evaluate the effect of visit number, patient expectation, and rater expectation of the efficacy of escitalopram treatment in fixed doses of 10 and 20mg, based on baseline severity in patients with MDD.
The Mayo Clinic psychiatric pharmacogenomic team has developed a pharmacogenomic algorithm that has been designed to improve the effectiveness and safety of antidepressant medications by providing guidance in medication selection and appropriate dosing. This algorithm has been incorporated into a new genotyping interpretative report. This report is now available from AssureRx. The pharmacogenomic algorithm is based on genotyping both copies of four informative genes. These four genes are: 1) the Cytochrome P450 2D6 gene; 2) the Cytochrome P450 2C19 gene; 3) the Serotonin Transporter gene (SLC6A4); and 4) the Serotonin 2A receptor gene (5HTR2A). Though this algorithm is not yet part of the universal standard of care, Mayo clinicians have found it helpful in guiding treatment decisions at Mayo Clinic Rochester.
The prevalence estimates for specific mental disorders and illicit drugs have been separately reported in U.S. government surveys. Less is known about the rates for specific comorbid conditions, e.g., schizophrenia and substance abuse, major depression and substance abuse, bipolar disorder and substance abuse, and anxiety disorder and substance abuse. The effects that different demographic characteristics (ethnic background, family medical history, age, living conditions [e.g., living with a single parent]) have on the prevalence of comorbid mental illness and substance abuse also have not been considered. More should be known about the duration of substance abuse in different mental illnesses among those undergoing treatment, and whether specific types of drugs are associated with specific mental illnesses. In this study, Advanced Clinical Laboratory Solutions, Inc. will investigate the prevalence rates for the specific comorbid conditions and demographic relationships described above. This multi-site, proof-of-concept cohort study will analyze urine or oral fluid samples from 1,000 subjects diagnosed with one of four mental illnesses (schizophrenia, major depression, bipolar disorder, or anxiety disorder) as determined by DSM-IV (The Fourth Edition of the Diagnostic and Statistical Manual of Mental Disorders). The samples will be analyzed for both prescription drug compliance and illicit substance abuse. Urine or oral fluid samples will be collected at three time points: 1) immediately after enrollment and obtaining informed consent, 2) randomly within 2 to 4 months of the study, and 3) at the end of the study (6 months).
