Major depressive disorder is the number one cause of disability worldwide. Evidence regarding the effectiveness of various treatments for patients with severe depression is still lacking. Although many patients achieve treatment response, only a minority of patients achieve full remission and even fewer sustain it. In fact, within one month 10% will be re-hospitalized and the rate climbs to 30% within a year. Further, remission from depressive symptoms is a surprisingly poor predictor of recovery of community functioning following discharge. It is clear that the traditional focus on diagnostic symptoms is insufficient for promoting a full return to everyday functioning. The present aim is to examine the efficacy and effectiveness of treating neurocognition, a symptom that explains persistent deficits in community functioning for those with depression. The study design that maps on to the contemporary clinical setting, in order to reflect the changing landscape of inpatient and community treatment.
The aim of the study is to evaluate in adult subjects with resistant depression the effect of an injection of botulinum toxin in the corrugator and procerus muscles, in comparison to the infiltration of the crow's feet area, in addition to the current antidepressant treatment.
This randomized trial with a crossover design will examine the efficacy of rTMS targeting the dorsomedial prefrontal cortex as a treatment for medication-resistant major depression in patients meeting diagnostic criteria for borderline personality disorder.
Eighty (80) subjects with Alcohol Use Disorder and Comorbid Major Depression, fulfilling all inclusion/exclusion criteria's will be randomly assigned to receive allogeneic human Mesenchymal stem cells or placebo in a 1:1 blinded fashion.
The focus of this application is on the impact of providing depressed Veterans and their providers with the results of pharmacogenetic (PGx) testing for psychotropic medications. The project focuses on whether and how patients and providers use genetic test results given to them at the time an antidepressant is to be initiated to treat Major Depressive Disorder (MDD) and whether use of the test results improves patient outcomes. MDD is one of the most common conditions associated with military service and combat exposure, increases suicide risk, and worsens the course of common medical conditions, making it a leading cause of functional impairment and mortality. Validation of a PGx test to personalize the treatment of MDD represents an important opportunity to improve the healthcare of Veterans.
The purpose of this research study is to find out if the medication known as ketamine can help the symptoms of depression. This drug is approved by the Food and Drug Administration (FDA) but the investigators will use it for a non-FDA approved reason (depression).
Background: The Human Brain Collection Core (HBCC) collects brain and other tissues. They get these from deceased people who may or may not have had psychiatric disorders. The next of kin gives permission for researchers to get the tissues. Researchers want to collect medical details of people whose brains are donated. They also want to use the donated tissue to study brain chemistry and structure. This could lead to better treatments for mental illness. Objective: To create a collection of human brain tissue to learn about the causes and mechanisms of mental disorders. Eligibility: People willing to donate their deceased relative s brain tissue. The deceased person could not have had any of the following: Severe mental retardation Long-lasting seizure disorder Infections that affect the brain Decomposition Brain damage Being on a respirator for more than 12 hours Major sepsis Serious renal or hepatic disease Certain dementias and degenerative diseases Design: Medical Examiner s Offices will screen donors who have recently died. Some others will be screened by hospitals or funeral homes. Participants will be the next of kin. They will give consent for HBCC to obtain brain tissue from the deceased person. The tissue will be frozen for future research. Participants will have a 30-minute phone call. They will answer questions about the deceased person s medical and psychiatric conditions. They will answer questions about the person s use of medicines and drugs. Participants will be contacted by a social worker. They will be asked for permission to access the deceased person s medical records.
The steroid hormone cortisol is released in response to stress and acts in the central nervous system upon glucocorticoid (GR) and mineralocorticoid receptors (MR). GR are widely distributed across the brain while MR are predominantly expressed in the hippocampus and prefrontal cortex - two brain areas closely related to memory and executive function. Stimulation of MR leads to an increase of glutamate that act on glutamatergic NMDA receptors in the hippocampus and prefrontal cortex. In previous studies, the investigators have shown that fludrocortisone, a mineralocorticoid receptor (MR) agonist, improves memory and executive function in depressed patients and healthy controls. However, depressed patients not only exhibit cognitive deficits in traditional neuropsychological domains such as memory or executive function. In addition, there are depression-specific alterations such as cognitive bias and deficits in social cognition, two clinically highly relevant areas. Therefore, the specific aims of this renewal proposal are two-fold: - To examine whether beneficial effects of fludrocortisone in depressed patients can be extended to depression-specific cognitive bias and to social cognition - To determine whether beneficial effects of fludrocortisone depend on NMDA-receptor function and whether these beneficial effects can be enhanced by NMDA receptor stimulation. The investigators hypothesize that fludrocortisone will improve cognitive bias and social cognition in depressed patients and that its beneficial effects depend on the NMDA receptor. Therefore, the investigators further hypothesize that the effects of fludrocortisone can be enhanced by co-administration of the partial NMDA receptor agonist D-cycloserine. The study not only advances current knowledge by further examining the mechanism of action by which MR stimulation exerts beneficial effects on cognition but extends these effects to depression-specific cognitive bias and alterations in social cognition. Furthermore, a potential interaction between MR and NMDA receptors is highly clinically relevant given the promising results with NMDA receptor antagonists in the treatment of major depression.
Major depression is a frequent psychiatric disorder with an estimated lifetime prevalence of 16-17% in the general population. Although its pathophysiology is not completely understood, a large body of literature pleads for a causative role of disturbances in reward processes, referring to: i) the hedonic sensation (i.e. "liking") defined by the pleasure felt after exposure to appetitive stimuli, and ii) the motivation (i.e. "wanting") represented by the ability to initiate and maintain behavioral responses oriented toward appetitive stimuli. the investigators have therefore developed and tested a new experimental computer-based and easy-to-use test intended to provide an objective and quantitative measurement of both hedonic and motivational states in humans. According to the task, the subjects are asked to view and to compare two stimuli, an appetitive one (food pictures) and its devalued counterpart (food pictures in greyscale), at each trial, assessing either the size (task A) or the duration of presentation (task B). From these considerations, the present project aims at using our novel tool to: i) assess the hedonic and motivational state in subjects with major depression, ii) compare their responses with healthy volunteers. The present project should demonstrate that the behavioral tests validated in our laboratory are relevant experimental tools for the diagnostic/clinical assessment and for the phenotypic characterization of depressed patients. The application of the test in the therapeutic context could add further information about the efficacy and relevance of the chosen therapy.
This study represents Phase II of a research program involving an international collaboration with Macquarie University (Sydney, Australia) to implement an Internet-based cognitive behavior therapy for the treatment of anxiety and depression in French-speaking Canadians from the Atlantic Provinces. The primary objective is to establish the clinical efficacy of a French-Canadian self-guided format version of the Wellbeing Course by conducting a randomized-control trial where an experimental group will be compared to a waitlist control group. A secondary objective is to demonstrate the course's acceptability through participants' satisfaction with the course.
