Filter by:The goal of this clinical trial is to demonstrate the feasibility and safety of deep brain stimulation in treatment resistant depression. The main questions it aims to answer are: - Is deep brain stimulation effective in treating treatment resistant depression? - Does deep brain stimulation improve overall clinical well-being and functioning? Participants will be implanted with a deep brain stimulation device. They will then be monitored over a 5-year period by using multiple questionnaires to track their depression symptoms. The device will be turned off at certain time points, unbeknown to the participant, to show the efficacy of the device when it is turned on. The device will be ON for 8.5 months and OFF for 3.5 months during the first year. Researchers will compare questionnaire scores when the device is off versus on to see if the device is working in reducing depression.
To explore the effectiveness and safety of rTMS intervention with different targets in the left prefrontal cortex defined using the pBFS method, in adult patients with moderate and severe depressive disorder. Second, investigate the neural circuit that responds to the rTMS intervention using individualized brain image analysis, which may help to establish an effective target for the neuromodulation of patients with major depressive disorder.
Participation in the CALYPSO project will be offered to all patients with severe depression hospitalized in the adult psychiatry department of Lille CHU. An initial visit will provide a standardized clinical assessment with: a medical history and history of the disease, a standardized structured Hamilton scale interview (scale with a score from 0 to 21; the higher the score, the more severe the depression) to assess the severity of depression, and a search for the different features of severe depression (melancholic, psychotic, anxious, catatonic, seasonal) using DSM-5 criteria (list of criteria to be validated to determine the type of clinical features). When assessing the severity of depression using the Hamilton scale interview, the patient will be seated in an armchair 2 to 3 meters from a camera on a tripod, positioned behind the clinician and enabling the entire interview to be recorded and, in particular, several observable and measurable psychiatric signs and symptoms, known as objective markers. From the video will be extracted face landmark and pose parameter using state-of-the-art open source software (Mediapipe) to analyze patients' emotional facial expressions and spatial movements. Moreover, a microphone will be used to capture the audio synchronously with the video. Speech will be automatically transcoded using state-of-the-art Automatic Speech Recognition system (DeepSpeech) to enable analysis of voice-related parameters (voice timbre, prosody, sound intensity). A recording of physical activity (3-axis accelerometer sensor; 32 Hz) and emotional reactivity (heart rate in beats per minute 1Hz; electrodermal activity 4 Hz; skin temperature in degrees 4 Hz; Empatica© bracelet) and brain activity (cerebral blood flow change index 10Hz; pulse rate in bpm 10Hz; 3-axis acceleration and angular velocity of the head 10Hz via functional Near-Infrared Spectroscopy (fNIRS) using a HOT-2000 wearable headset) will also be offered to the patient to complete the assessment. The Hamilton scale interview and recording of objective markers will be carried out weekly during the patient's hospitalization in an examination room specifically equipped for the project, on the second floor of the Fontan Hospital, in the psychiatry department of the Lille University hospital. Longitudinal follow-up will be carried out with assessments at 3, 6 and 12 months after hospital discharge, including the Hamilton scale interview and recording of objective markers (i.e., emotional facial expressions, spatial movements, voice timbre, prosody, sound intensity, physical activity, heart rate, electrodermal activity, skin temperature).
This study aims to evaluate the acute and subacute effects of an inhaled N, N-Dimethyltryptamine (DMT) in patients with partial response in depression.
The R33 will be a randomized controlled trial to replicate changes in the targets (unproductive processing, avoidance, reward deficits) from the R61 phase in a larger sample of 135 participants who have experienced a destabilizing life event involving profound loss or threat, report persistent stressor-related symptoms of PTSD and/or depression, and are elevated on symptoms related to 2 of the 3 therapeutic targets. Additionally, this study will examine Positive Processes and Transition to Health (PATH)'s impact on stressor-related psychopathology in comparison to Progressive Muscle Relaxation (PMR). In the R33 phase, the investigators will examine changes in target mechanisms predicting improvements in PTSD and depressive symptoms, as well as feasibility and acceptability. Patients will receive 6 sessions of PATH or PMR (with 2 boosters, if partial responders). Primary targets will be assessed at pre-treatment, week 3, post-treatment, and at 1- and 3-month follow-up; secondary targets at pre-treatment, weekly during treatment, post-treatment, and at 1- and 3-month follow-ups.
The goal of this prospective randomised controlled trial is to examine the effects of cognitive behavioural therapy and bright light therapy in youths with unipolar depression and evening chronotype. The main questions it aims to answer are: 1. What is the efficacy of CBT-D and CBT-D plus bright light therapy in reducing depression severity in adolescents with depression and eveningness? 2. What are the effects of CBT-D and CBT-D plus bright light therapy on the subjective and objective sleep and circadian measures, as well as the quality of life, daytime symptoms, and functioning (e.g., sleepiness, fatigue)? Participants will participate in 8 weekly group sessions of CBT-D intervention based on the well-established CBT elements for treating depression. Concurrently participants will also be asked to wear a portable light device at home for 30 minutes daily for seven weeks, starting from the second week of the group intervention. Participants in the CBT-D only group will receive a placebo light via the device, whereas participants in the CBT-D plus light therapy group will receive the active bright light via the device.
The goal of this single-center, single-blind, randomized, controlled, parallel group, interventional trial to evaluate antidepressant efficacy of yoga monotherapy of 12-weeks duration in 180 adults meeting diagnostic criteria for mild-to-moderate major depression at the Zuckerberg San Francisco General Hospital. Researchers will compare the yoga interventions to a an education control intervention on holistic healthcare.
Depression is a debilitating chronic illness affecting 1 in 6 adults in the United Kingdom (UK) at any one time. Antidepressants and psychological therapy are the main treatments, but some people do not respond to these. Neurons and signals in the brain are greatly disrupted in people with severe depression. A ketogenic diet, a high-fat and very low-carbohydrate diet, supplies a form of energy that appears to help brain cells communicate and may improve the treatment of depression. Our goal is to find out whether a ketogenic diet could be an additional effective treatment for patients with depression for which antidepressants do not work. Using social media advertising, 100 patients, ages 18-65, who have previously tried at least two different antidepressant medications within the current depressive episode will be recruited. Enrolment, consent, and data collection will be collected online using self-report questionnaires. Participants will be allocated by minimisation 1:1 to the KD group or control group based on depressive severity (moderately severe vs. severe) and body mass index (<30kg/m2 vs. 30+ kg/m2). The intervention group will receive 6-weeks of prepared ketogenic diet meals (3 meals with snacks per day) and weekly ketogenic diet-focused nutrition counselling. The control group will be asked to follow a diet to reduce their saturated fat intake and increase vegetable consumption by one portion a day. The control group will receive vouchers to assist with purchases and will be provided with weekly nutritional counselling. Existing treatment for depression will remain in both groups. The primary outcome is the change in depression symptoms at six weeks. All participants will complete assessments of depression and anxiety every two weeks, starting before treatment to post-intervention (week 6), and again at week 12. Additional outcomes include participants' ability to experience pleasure, quality of life, ability to socialise and work, cognitive processing, morning cortisol, and gut microbiome. At all stages of the study, adults with lived experience of depression will advise the research team to take into account the needs and views of patients. This study will provide evidence of whether following a ketogenic diet leads to a short-term improvement in depression in people whose depression cannot be relieved by antidepressants.
The goal of this clinical trial is to investigate the effects of ketamine, in combination with standard inpatient addiction therapy, for adults with depression and alcohol use disorder. After screening and enrollment, participants will undergo baseline assessments of depression, measures of alcohol use and craving, as well as neurocognitive function. Participants will then be randomized to either ketamine (intervention) or midazolam (control). All participants will be admitted for standard inpatient addiction therapy while receiving ketamine or midazolam. Measures on safety, depression and alcohol use disorder will be repeatedly assessed during and after treatment. Final follow-up assessment is scheduled 6 months after baseline assessment.
This is a 2x2, within-subjects, cross-over trial to test the anti-depressant effects of acute exercise in 20 participants with bipolar depression. Participants will complete four experimental sessions, two with an exercise challenge and two with a resting control condition in a counterbalanced order. Participants will receive either 800mg of ibuprofen or placebo before exercise or rest in order to test whether blocking the inflammatory response to exercise interferes with the neural and psychological effects of exercise.
