Filter by:The purpose of the study aims to determine whether different concentrations of nitrous oxide (N2O) have different antidepressant effects for adults with treatment-resistant major depression.
The primary aim of this study is to determine if a behavioral intervention targeting maternal caregiving of young infants can increase infant sleep and reduce fuss/cry behavior, and thereby (1) reduce the incidence and/or severity of postpartum maternal depression and (2) improve the quality of the mother-infant interaction and subsequent child development. Specifically, the study team will investigate: (1) the effectiveness of the intervention compared to usual care; (2) if the effects of the intervention can be detected in the assessments of the quality of mother-infant interaction; (3) if there are prenatal and/or postnatal biomarkers that can help identify infants whose behavior is more likely to play a role in their mothers' depression; (4) if these markers differentiate which infants will be most responsive to the intervention(s); and (5), if assessments of brain function at birth and at 4-6 weeks of age provide biological nodal points for identifying the effects of the intervention on infant brain development. Participants will be recruited during their 2nd trimester, and will be randomly separated into one of two groups: a group that receives coaching in parenting techniques (4 in-person coaching sessions and 1 phone session) or one that receives treatment as usual.
This pilot study will explore the feasibility and acceptability of implementing a family-based treatment, using HIPAA-compliant video-based communication technology, for adolescents (pregnant and post-delivery) with peripartum depressive symptoms within the context of home visiting.
Experimental and clinical studies have indicated that acupuncture has a good effect for depression and comorbid pain. The purpose of this research is to compare the effect of comprehensive electro-acupuncture therapy and western medicine citalopram for for depressive disorder with comorbid psychogenic pain. This research is a assessor blinded, randomized controlled trials. 60 patients will be randomly divided into comprehensive electro-acupuncture group and western medicine citalopram for 8 weeks treatment and the therapeutic effect is done at the end of 1,2,4,6,8 week.
The prevalence of psychiatric disorders such as major depression disorder (MDD) is increasing rapidly. Despite advancements in the development of therapeutics, current treatment options have not reached optimal efficacy. Recent interest has been drawn towards the importance of the biochemical signalling between the gastrointestinal tract and the central nervous system also known as the "microbiome-gut-brain axis". The pathogenesis of gut microbiota in extra intestinal diseases was inspired by massive studies in germ free (GF) animals, which indicated that the gut microbiota plays a role in the normal regulation of behaviour that are relevant to mood, anxiety and stress. However, the exact mechanisms by which intestinal dysbiosis are involved in the development of psychiatric diseases are not completely clarified. A new method to alter the composition of the gastrointestinal microbiota involves fecal microbiota transplantation (FMT). The goal of FMT is to introduce or restore a stable microbial community in the gut by transplanting intestinal microbiota from a healthy donor to the patient. FMT, as a microbiota-target therapy, is arguably very effective for curing recurrent Clostridium difficile infection and has good outcomes in other intestinal diseases. At the same time, applications in previously unexpected areas, including metabolic diseases, neuropsychiatric disorders, autoimmune diseases, allergic disorders, and tumors have shown health enhancing results. FMT has initially been conducted using colonoscopy. However, recent evidence has shown that treatment with frozen FMT capsules (to be taken orally) is also safe and beneficial in restoring the gut microbiota in patients with various diseases As FMT capsules may be an effective, pragmatical adjuvant therapy (in addition to standard treatment) for depression, this project is aimed at (1) investigating for the first time if single administration of FMT capsules ameliorates depressive symptoms in patients with moderate to severe MDD 4 weeks after treatment and (2) establishing the safety profile of encapsulated FMT in MDD. Furthermore, we will also test if (3) FMT capsules modulates immune signalling and inflammatory processes, (4) Hypothalamic-pituitary-adrenal (HPA) axis responses, (5) neurogenesis, (6) energy balance hormones, (7) gut microbiota composition and (8) brain perfusion, structure and activation.
Neurofeedback is an increasingly researched technique for the treatment of many psychological disorders, such as attention deficit / hyperactivity disorder (AD / HD), depression, or substance abuse. This technique would allow patients to regulate their cortical electroencephalographic activity while receiving a visual or auditory feedback on the cortical electroencephalographic activity. Changes in the electroencephalogram (EEG) would thus be correlated with changes in cortical activity and thus with symptoms. On the electroencephalographic plane, the depression appears associated with relatively more alpha activity (in "resting state", 8-13 Hz) in left than in right frontal cortex. This difference in alpha activity between frontal regions is known as alpha asymmetry in depression. As a reminder, increased alpha activity indicates a decrease in cortical activation. This alpha asymmetry appears to be associated with a decrease in sensitivity to reward. It is on these bases that the modification of the alpha asymmetry has become one of the most frequent objectives of the studies on the use of neurofeedback in depression. Transcranial magnetic stimulation (TMS) also offers a non-invasive and painless method of effective cerebral stimulation in psychiatric disorders and especially depression. It received a favorable opinion from the Food & Drug Administration (FDA) in the United States for the treatment of this pathology. This treatment is still under evaluation in France. The results are promising but improvements must be done to increase its effectiveness. TMS offers stimulation of brain tissue in a localized and non-invasive manner. The principle consists of a brief electric current passing through a coil which generates a transient magnetic field inducing an electric field through conductive fabrics. TMS modifies neuronal activity in target superficial brain structures, but also modulates neuronal circuit activity. In recent years, the concept of "state dependency TMS" has been developed. It suggests that the activation state of neuronal circuits before and after stimulation alters the effect of stimulation. Thus, the efficacy of TMS could be amplified in depression by taking into account the cerebral activity during the stimulation sessions, in particular on the electroencephalographic plane. However, TMS may also help patients increase their EEG response during Neurofeedback sessions. The combination of stimulation techniques and brain-machine interfaces such as neurofeedback is still little studied at present. A study on the combined use of TMS and Neurofeedback by EEG in depression would therefore be an innovative approach and in line with the latest data from the literature. Design : Prospective, monocentric, non-randomized, non-comparative, unblinded study.
Depressed patients unremitted after monotherapy with citalopram or bupropion will remit following six weeks treatment with the combination of citalopram and bupropion.
The purpose of this research study is to determine whether Nexalin Trans-Cranial Electrical Stimulation (TES) is an effective treatment for depression among patients who are candidates for ECT. A secondary aim to assess whether Nexalin can be used as an alternative to ECT. Although Nexalin has been approved for use in the US, using Nexalin to treat depression in this way is investigational and experimental. If Nexalin is found to be an alternative to ECT, it could offer a safer treatment for depression with less side-effects and a lower cost. !!! NOTE !!! Post Script / Post Study. The ECT arm (profiling subjects as ECT accepters vs. rejecters) was dropped owing to site objections by referring clinicians. Accordingly, the study was framed as a simple comparison between TES and SHAM TES.
Preclinical and clinical studies have shown that consuming probiotics can improve mood, anxiety, and cognition, as well as alter brain activity in both rodents and healthy humans. Data from our recent open-label, 8-week pilot study provided the first evidence of these effects in depressed patients, with significant improvements observed in overall mood, anhedonia, and sleep quality. To further support this evidence and expand upon the search for biomarkers in depression, data from this pilot study is being used to plan a 16-week, double-blind randomized placebo-controlled trial to assess the effects of probiotics on depression. Participants diagnosed with depression recruited from the greater Kingston area will orally consume a probiotic supplement containing Lactobacillus helveticus and Bifidobacterium longum (Probio'Stick, Lallemand Health Solutions) or placebo once daily. Participants will undergo clinical assessments measuring mood, anxiety, cognition, and sleep using a battery of validated clinical scales to assess efficacy of the probiotic alleviating depressive symptoms; sleep will also be assessed objectively with an ambulatory polysomnogram. Neuroimaging data will be collected using magnetic resonance imaging and electroencephalography to look at functional, structural, and electrical changes in the brain associated with consumption of the probiotic. Molecular data will be collected from blood, stool, and urine samples to look at levels of cytokines and serotonin, and explore potential genes and proteins that may predict outcomes in depression. An informatics-based approach will be used to integrate clinical, neuroimaging, and molecular data to look for biomarkers that indicate disease state and predict antidepressant-like response to the probiotic. Results: We expect results to replicate and expand on our pilot data, demonstrating that probiotics are effective in alleviating symptoms of depression, and to find biomarkers that will predict these outcomes. The findings from this study will contribute robust scientific data that is currently lacking in this emerging field.
This study originally included 100 subjects with medication-refractory depression undergoing 10 Hz transcranial magnetic stimulation (10Hz-TMS) to the left dorsal lateral prefrontal cortex (DLPFC), with the goal of having 60 completers with good quality data. Subjects were recruited from the TMS clinics at Beth Israel Deaconess Medical Center, Brigham & Women's Hospital, and Butler Hospital. Subjects underwent an hour-long MRI scanning session, an optional DNA-sample collection, up to three 20 minute neuronavigation sessions for marking the site of TMS stimulation, questionnaires, and a behavioral testing battery before and after their TMS treatment course. The task battery included the Emotion Conflict Resolution (ECR) task, Multi-Source Interference Task (MSIT), War Game (Gambling) task, and Associative Learning with Reversal task. Subjects' scores on the Quick Inventory of Depressive Symptomatology (QIDS) and Beck Depression Inventory (BDI) were assessed before and after the TMS course. MRI data was utilized to identify brain regions whose connectivity to the stimulation site co-varies with the aforementioned measures of symptom improvement. This was the only study group until August 30, 2022, and the primary outcome was analyzed for the 10Hz-TMS group. Due to changes in clinical standard of care from 10Hz-TMS to a newer version of TMS termed intermittent theta burst (iTBS), in September 2022 a second group was added to include patients receiving this new form of TMS. This second group included another 100 patients with medication-refractory depression undergoing iTBS to the left dorsal lateral prefrontal cortex (DLPFC), with the intent to have 80 completers. Massachusetts General Hospital was added as a data collection site in lieu of Butler Hospital. Subjects will undergo an hour-long MRI scanning session, up to three 20 minute neuronavigation sessions for marking the site of TMS stimulation, questionnaires, and a behavioral testing battery before and after their TMS treatment course. The task battery will included the Emotion Conflict Resolution (ECR) task, Multi-Source Interference Task (MSIT), Penn Emotion Recognition Test, the Suicide/Death Implicit Association Test, and Associative Learning with Reversal task. Subjects' scores on the Beck Depression Inventory (BDI) were assessed before and after the TMS course. MRI data will be utilized to identify brain regions whose connectivity to the stimulation site co-varies with the aforementioned measures of symptom improvement.
