Filter by:This is a prospective clinical cohort study of depression. The study was intended to include 300 patients with depression and 100 healthy controls. The study consisted of two phases: the baseline period and the follow-up period, in which all subjects were comprehensively collected, and the follow-up period in which all subjects were followed up at least once a year and data were collected. For patients with major depressive disorder, the follow-up methods included fixed visit and planned visit, and the follow-up time point covered the whole course of depressive disease(baseline, 2nd weekend±7days, 6th weekend±14days, 8th weekend±14days, 12th weekend±14days, Week 14-104 Every 4 weekends ± 14 days). Based on standardized, multi-strategy follow-up system and mobile health technology, long-term follow-up of patients with major depressive disorder was realized, and key nodes of patients' disease fluctuations were captured in time. High quality multidimensional data were collected, including demographic, clinical, EEG and eye movement data. Finally, the objective index system of depression was constructed, and the diagnosis, efficacy/recurrence prediction and suicide warning models of depression were established.
The goal of this clinical trial is to determine the impact of omega-3 fatty acids on the production of anti-inflammatory effects and clinical improvement in people with depression who have not responded well to standard antidepressant treatment. The main questions it seeks to answer are: 1. Do omega-3 fatty acids added to ineffective antidepressant treatment increase production of compounds that reduce inflammation? 2. Is the increase in these anti-inflammatory compounds associated with a stronger antidepressant effect? Participants taking antidepressants that have not worked completely will be assigned at random for a 12-week period to one of the following: 1. an omega-3 preparation 2. an inactive placebo During the course of the study, blood tests will be obtained for compounds associated with inflammation, and questionnaires to measure clinical improvement in depressive symptoms will be administered.
Of the estimated 30 million Americans who suffer from Major Depressive Disorder, approximately 10% are considered treatment resistant. Deep brain stimulation (DBS) to a region of the brain called the subcallosal cingulate (SCC) is an emerging strategy for treatment resistant depression (TRD), which involves placement of electrodes in a specific region of the brain and stimulating that area with electricity. This is believed to reset the brain network responsible for symptoms and results in a significant antidepressant response. A series of open-label studies have demonstrated sustained, long-term antidepressant effects in 40-60% of patients who received this treatment. A challenge to the effective dissemination of this fledgling treatment is the absence of biomarkers (objective, measureable indications of the state of the body and brain) to guide device placement and select stimulation parameters during follow-up care. By using a DBS device called the Percept PC (Medtronic, Inc) which has the ability to both deliver stimulation to and record electrical signals directly from the brain, this study aims to identify changes in local field potentials (LFPs), specific electrical signals that are thought to represent how the brain communicates information from one region to another, to see how this relates to DBS parameter settings and patient depressive symptomatology. The goal of this study is to study LFPs before and during active DBS stimulation to identify changes that correlate with the antidepressant effects of SCC DBS. The study team will recruit 10 patients with TRD and implant them with the Percept PC system. Participants will be asked to complete short questionnaires and collect LFP data twice daily for the first year of the study, as well as have weekly in person research procedures and assessments with the study team for up to one year. These include meetings with the study psychiatrist, psychologist, symptom ratings, and movement, voice, and video recordings. A brief discontinuation experiment will be conducted after 6 months of stimulation, in which the stimulation will be turned off and patterns of LFP changes will be recorded. The entire study is expected to last about 5 years, parcellated into several study phases. All participants are required to live in the New York metropolitan area for the first several months of the study.
The goal of this longitudinal study is to study the effects of a parenting skills group (Circle of Security Parenting, aka COSP) in mothers with postpartum depression. The main questions it aims to answer are: - Will changes in methylation of the OXTR rs53576 be apparent in mother and/or infant after having gone through the 8-week COSP program? - Will COSP participation be associated with improved symptoms of postpartum depression (over and above standard care), attachment style, and relational characteristics of the mother-infant dyad? - Will COSP participation be associated with changes in social behavior in the infant, and if so, do they persist throughout childhood? Participants will - Participate in an 8-week COSP program delivered remotely via Zoom. - Provide buccal swabs (mother and infant) to assess changes in methylation of OXTR rs53576 pre- versus post-intervention. - Complete a series of assessment questionnaires delivered remotely. - Videotape a play-based assessment in their home. - Receive infant developmental testing Researchers will compare characteristics of waitlist controls to those participating in the COSP program at the mid-way point of the program to see if the two groups differ.
The purpose of this research study is to study closed-loop transcranial alternating current stimulation (tACS) to determine its effects on symptoms of depression in people with major depressive disorder.
This study aims to identify the influence of social determinants of health domains on vascular function in a low income, racial, and ethnic minority population at risk for disparities. We hypothesize that individuals of a lower social economic position and those struggling with depression are at greater risk of cardiovascular disease.
The goal of this clinical trial is to test the beneficial effects of rivastigmine administration, and predict the treatment outcome with electroencephalography (EEG), in patients with severe depression treated with electroconvulsive therapy (ECT). The study has two main objectives: - to study whether rivastigmine would ameliorate the side-effect profile of ECT - to develop an outcome prediction model based on resting state EEG for both the response to treatment as well as its side effect Participants will be assessed by: - Cognitive tests - Questionnaires of clinical symptoms - Questionnaires of depressive symptoms - Bloodsample - Resting state and task-based EEG Researchers will compare patients with a depressive disorder treated with ECT receiving rivastigmine to placebo patches to see if rivastigmine reduces cognitive side effects.
Aims: 1. To describe the process of developing a feasible district mental healthcare plan (MHCP) for depression, self-harm and suicide prevention, and 2. To describe its enabling intervention packages and components to be delivered at the Basic Health Units in Thatta district. The proposed study will be a pilot implementation with nested qualitative component. The study will also involve situational analysis for proposed study site and Theory of Change workshops with key stakeholders. This study is a replication of the methods used in the development of a district mental healthcare plan in Uganda (Kigozi et al., 2016).
Objective: Wearable technology holds promising potential for mental health monitoring and detection. Samsung has developed an algorithm that they believe can detect signs of depression and anxiety in smartwatch users. They have used this algorithm to create a "Mindfulness Index," which is an easily understood visual index of mental health. The primary aim of the study is to evaluate the performance of Samsung's Mindfulness Index in identifying those who have received a diagnosis of Major Depressive Disorder (MDD) from a clinician-administered semi-structured diagnostic interview. Research Procedures: The target sample size is 75 individuals diagnosed with current Major Depressive Disorder and 75 healthy controls. To meet this target, the recruitment target is set at 215 participants. Participants will be assigned to the MDD condition, or the healthy control condition based on their score on the Beck Depression Inventory. Each subject will be followed for 3 months. Participants will be provided with a Samsung smartphone and Samsung smartwatch. Participants will be asked to wear the smartwatch 24 hours per day, except while charging. This smartwatch will collect data on heartrate, sleep time, and step count. During the study, each day participants will receive texts prompting a link to a "daily diary." These surveys will ask about depression and anxiety symptoms. Additionally, during the first 3 weeks of the study, participants will participate in ecological momentary assessment; texts will be sent 5 times per day prompting participants to fill out a survey about how they currently feel in that moment. These extra surveys will stop after the first 3 weeks of the study, but the daily diary surveys will continue throughout the study. Furthermore, virtual clinician visits will occur at weeks 4, 8, and 12.
The purpose of the study is to test whether changes in behavioral patterns are related to changes in depression. Depression is a psychological condition that involves persistent sad mood and/or an inability to enjoy pleasurable activities. Very stable behavioral patterns may be related to symptoms of depression. The aim of this study is to learn more about the relationship between symptoms of depression and behavioral patterns that are collected via GPS (global positioning system) location data from a smartphone.
