Neural Mechanisms of Meditation Training in Healthy and Depressed Adolescents: An MRI Connectome...
Depression MildDepression Moderate2 moreThe primary objective will be to study changes in putamen connectivity and depression severity in depressed teens with meditation training. H1: Putamen node strength will increase in the training group compared to the active controls. H2: This increase in node strength will correlate with practice amount recorded by participants. H3: There will be a significant reduction in self-rated depression symptoms following the training as measured by the Reynolds Adolescent Depression Scale (RADS-2), compared to controls. H4: This reduction will correlate with the increase in putamen node strength. Design and Outcomes: The current research study design will utilize an individually randomized group treatment, open-label, active-controlled clinical trial to test the efficacy and safety of the investigator's innovative mindfulness meditation intervention (Training for Awareness Resilience and Action [TARA]) on the primary outcome (Putamen structural node strength) and secondary outcome (depression symptoms measured using Reynolds Adolescent Depression Scale [RADS-2]) in depressed adolescents between the ages of 14 to 18 years old.

The aim of this study was to evaluate the effects of ECT in individuals at UFTM Hospital de Clínicas. Methods: Randomized controlled trial, patients were randomly. Patients will then be allocated into groups: The group submitted to ECT (prayer, spiritual education, spiritist "passe" and fluidized water or prayer or spiritist "passe" or laying on of hands with intent to heal or laying on of hands with intent to heal or fluidized water or no-fluidized water or Control group (CG) will not be submitted to any intervention.
The Role of Hormones in Postpartum Mood Disorders
Postpartum DepressionDetermine whether postpartum depression is triggered by the abrupt withdrawal of estrogen and progesterone. The appearance of mood and behavioral symptoms during pregnancy and the postpartum period has been extensively reported. While there has been much speculation about possible biologically based etiologies for postpartum disorders (PPD), none has ever been confirmed. Preliminary results from two related studies (protocols 90-M-0088, 92-M-0174) provide evidence that women with menstrual cycle related mood disorder, but not controls, experience mood disturbances during exogenous replacement of physiologic levels of gonadal steroids. The present protocol is designed to create a "scaled-down" hormonal milieu of pregnancy and the puerperium in order to determine whether women who have had a previous episode of postpartum major effective episode will experience differential mood and behavioral effects compared with controls and to determine whether it is the abrupt withdrawal of gonadal steroids or the prolonged exposure to gonadal steroids that is associated with mood symptoms. Supraphysiologic plasma levels of gonadal steroids will be established, maintained, and then rapidly reduced, simulating the hormonal events that occur during pregnancy and parturition. This will be accomplished by administering estradiol and progesterone to women who are pretreated with a gonadotropin releasing hormone (GnRH) agonist (Lupron). After eight weeks, administration of gonadal steroids will be stopped in one group of patients and controls, and a sudden decline in the plasma hormone levels will be precipitated. Another group will be maintained on supraphysiologic levels of estrogen and progesterone for an additional month. Outcome measures will include mood, behavioral and hormonal parameters (a separate protocol done in collaboration with NICHD).
Food for Mind - Intervention in the Treatment of Depression
DepressionAims. The main aim of the study is to explore whether Food for Mind - Group-based behavioral nutrition intervention alleviates depression symptoms. Furthermore, we aim to investigate, whether the intervention improves the quality of diet, eating habits, quality of life, ability to work and to study its cost-effectiveness. In collaboration with 11 public and private health care service providers in cities of Kuopio and Siilinjärvi in Northern Savo, Finland. Participants. The total number of subjects will be 144 based on power calculations. The calculation is based on the clinical decline of seven points assessed by the Center for Epidemiologic Studies Depression (CES-D) Scale. Participants sign an informed consent form to participate Food for Mind - intervention. Study design. In this randomized controlled clinical trial subjects are randomized into two parallel groups: Food for Mind -behavioral nutrition intervention group (n=72) and Group to bring Good Mood -control group (n=72). The intervention consists of behavioral nutrition counselling (5 times 1½ h and 1 time 3 h) and the control group (befriending group) (n=72) (5 times 1½ h and 1 time 3 h). Thus, in the befriending group the same visit schedule and length without any nutrition counselling is used. The befriending group consists of discussion of neutral topics, like hobbies, music, sports, and doing together. Both groups continue to have their normal depression care in the health care. Enrollment and treatment will take about four years, and follow-up will last about one year. The Northern Savo Hospital District Committee on Research Ethics gave its consent to the study protocol. Methods. All questionnaires are validated. CES-D -depression scale, Seasonal Pattern Assessment Questionnaire, The Diet Quality Index (IDQ), Diet frequency -questionnaire, Eating competence -questionnaire (ecSI 2.0), The Three Factor Eating Questionnaire, Ability to work and function -questionnaires, Assessment of Quality of Life (AQoL)-8D (8 dimensions) -questionnaire, Treatment expectancy -questionnaire, Acceptability -questioinnaire. In addition, body composition measurement and cost-effectiveness analyses to evaluate the health outcomes in relation to resource utilization and costs in Food for Mind -intervention.
Mechanism of Action Underlying Ketamine's Antidepressant Effects: The AMPA Throughput Theory in...
DepressionMajor Depressive Disorder1 moreBackground: Most drugs that treat mood disorders take a long time to work. Ketamine works within hours. A dose can last for a week or more. Certain receptors in the brain might help ketamine work. A drug that blocks these receptors might affect how it works. Objective: To see if the antidepressant response of ketamine is linked to AMPA receptors. Eligibility: Adults ages 18-70 with major depression disorder without psychotic features Design: Participants will be screened under protocol 01-M-0254. They will have blood tests and a physical exam. Participants will stay at the NIH Clinical Center for 5 weeks. Phase 1 lasts 4 weeks. For 2 weeks, participants will taper off their psychiatric medicine. Then they will have the following tests: Blood draws Psychological tests MRI: Participants will lie in a machine that takes pictures of their brain. MEG: Participants will lie down and do tasks. A cone lowered on their head will record brain activity. Optional sleep tests: Electrodes on the scalp and body and belts around the body will monitor participants while they sleep. Optional TMS: Participants will do tasks while a wire coil is held on their scalp. An electrical current will pass through the coil that affects brain activity. For phase 2, on day 0 participants will take the study drug or a placebo orally. While having a MEG, they will get ketamine infused into a vein in one arm while blood is drawn from a vein in the other arm. On day 1, participants will again take the study drug or a placebo orally. On days 3-7, they will repeat many of the phase 1 tests. Days 8 and 9 are optional and include an open label ketamine treatment and many of the phase 1 tests.
Brain Stimulation and Decision-making
DepressionDecision-making is an important process that is frequently shown to be impaired in patients with depression. While a number of preclinical and clinical studies have identified key regions involved in this process, it remains unclear exactly how these regions are influencing choice behavior especially when choices become more challenging. The goal of this project is to understand how these regions, such as the cingulate cortex, impact difficult choice behavior. Specifically, the researchers are interested in learning how disruptions in cognitive control might impact choice preferences during difficult decisions in depressed patients. To do this, this study will recruit participants with depression (as well as healthy controls) to perform game-like tasks in the laboratory while undergoing TMS or TI.
Alleviating Stress by Mobile Application' for Depression
Major Depressive DisorderThis study is a single-blind, multicenter, randomized, controlled crossover trial. The App, developed in South Korea, is an application that provides integrated interventions for stress reduction for the general population. The App provides three contents based on MBSR, CBT, and relaxation sounds that are known to be effective in stress reduction ("Meditation category", "Cognitive approach", and "Relaxation Sound", respectively). Participants (n = 215) recruited via medical practitioner referral will be randomized to App first group (fAPP) or a waitlist crossover group (dAPP). Inclusion criteria are age 19-65; diagnosed with mild to moderate major depressive disorders (Score of 7-24 on the Hamilton Rating Scale for Depression); Stable medication for 28 days prior to study participation. The study was conducted over eight weeks, the fAPP group used The App for the first four weeks and the dAPP group for the next four weeks, and during all study periods, the participants received usual pharmacological treatment. Primary outcome measures are the Depression Anxiety Stress Scale-21. The analysis will use mixed-model repeated measures.
Reward Emotion Learning and Ketamine Study
DepressionMajor Depressive Disorder1 moreKetamine's efficacy as an antidepressant is now well established yet the mechanisms underlying its antidepressant effect are yet to be fully described. Work in the animal literature and research in humans is suggestive of specific effects on anhedonia and memory reconsolidation. In this study the investigators will further explore the effects of ketamine on learning and memory as well as measuring the associated changes at neural level in a sample of healthy volunteers. Participants will be assigned to receive ketamine or placebo and complete a set of tasks which will allow the investigators to quantify the effect of ketamine on learning about reward and punishment and memory for learned reward associations 24 hours after ketamine infusion. This study will help the investigators to understand the basis of ketamine's antidepressant effects and aid the development of new treatments for depression.
eMBC for Perinatal Depression and Anxiety
DepressionPostpartum1 moreDepression and anxiety that occur around the time of pregnancy can adversely impact a person's health and well-being, and their child's health and development. Fewer than 20% of affected people are adequately treated, often because of under-use of medications. Measurement based care (MBC) is a model of care where psychiatric symptoms are routinely tracked and reviewed together by a patient and their doctor to better manage symptoms. It has not been systematically evaluated for perinatal depression and anxiety. The overall objective of this study is to test the feasibility of MBC in this population to inform a future large randomized controlled trial for definitive evaluation. In order to avoid known barriers to MBC, electronic MBC (eMBC) will be used. With eMBC, patients can enter their symptoms into their electronic medical records before their appointment so that they can be evaluated by their doctor during the appointment. In this pilot study, the feasibility of recruitment for a future efficacy trial, including feasibility of recruitment, and retention, acceptability and adherence to a trial protocol will be evaluated.
