Filter by:The overall goal of the proposed project is to investigate the neuronal pathways regulating the effects of social acceptance and rejection in healthy controls and patients with Major Depressive Disorder (MDD). Social acceptance and rejection are defined as the explicit declaration that an individual is liked or not liked. Social acceptance can boost one's self-esteem and mood, whereas rejection can lower them. The neurological relationship between social acceptance/rejection and depressive symptoms is not known. Using functional magnetic resonance imaging (fMRI), it is hypothesized that social feedback will activate a specific interconnected neuronal pathway involved in social separation and reward. Executive functioning and response to monetary reward will also be assessed during fMRI using two additional tasks (monetary incentive delay, parametric go no-go) to determine how these cognitive brain functions regulate responses to social feedback.
Major depressive disorder (MDD) is the leading cause of disability in the developed world and is associated with lost productivity, increased health care utilization, and mortality. Several empirically supported treatments, such as antidepressant medication and cognitive behavioral therapy, exist for the treatment of MDD; however, studies have shown that as many as 34% of individuals do not respond to these treatments. Exercise and stretching interventions represent alternative strategies associated with strong effect sizes in past studies. Additionally, exercise has been shown to enhance cognitive functioning, especially attention and memory. This study aims to investigate the effect of a combined aerobic exercise and behavioral activation treatment (BA) for MDD. Behavioral activation treatment involves completing both pleasant and mastery-based activities with the goal of enhancing mood. The current study will recruit 32 MDD patients for an active treatment phase of nine 60-90 minute sessions (6 weekly sessions and 3 biweekly sessions) of either BA plus exercise (BA+EX) or BA plus stretching (BA+STR). The purpose of this study is to identify if adding aerobic exercise to a brief psychosocial treatment can improve mood above and beyond an active control condition.
The purposes of this project are to examine the feasibility, safety, tolerability and clinical effect of low-dose buprenorphine as a novel treatment for late-life treatment-resistant depression and to develop preliminary data about mechanism of action.
This study will evaluate a Smartphone intervention for depression and anxiety that uses machine learning to tailor treatment for patients. The intervention, referred to as IntelliCare, delivers patient-specific treatment material and motivational messaging via a mobile phone, to help individuals with depression and/or anxiety. Information and data received from the patient will inform the tailored treatment approach through machine learning. The purpose of this study is to obtain preliminary information on the feasibility and effectiveness of IntelliCare in improving symptoms of depression and anxiety.
The drug Ketamine, available in medical practice since the late 1960s, is currently used for inducing general anesthesia or sedation during medical procedures. When given slowly as an injection into a vein, ketamine is shown to produce a very rapid effect on depression and to improve depressive symptoms within hours to days. By studying patients who receive a ketamine IV infusion, as an add-on treatment for depression, investigators may start to understand how changes in the brain or in gene function relate to getting better over a very short period of time. In this study, the investigators will enroll 60 patients currently ill with major depression selected to receive IV ketamine therapy under medical supervision. To study neurobiological changes relating to symptom improvement, the investigators will use advanced brain scans to measure brain structure, chemistry and function. Blood samples will measure changes in gene regulation and immune system response. Although some people have a rapid antidepressant response to ketamine, others do not respond. Also, antidepressant effects after ketamine usually wear off within days to weeks. We will determine if up to four doses of ketamine delivered two to three times a week may prolong antidepressant response to ketamine therapy. To determine the durability of ketamine treatment for depression, patients will be monitored by phone and via electronic devices twice a week for up to five weeks and will return for a final assessment when their symptoms return. For this trial, brain and blood sample measurements will occur before and after a patient receives their first ketamine infusion. Patients who do not remit after an initial dose of ketamine, will receive up to three additional ketamine treatments. Mood will be measured 24-hours after each subsequent ketamine infusion and brain and blood measurements be repeated at the time of remission or after the fourth ketamine infusion if remission does not occur. Patients will return for a final brain scan and blood sample when their depressive symptoms return or at five weeks if they continue remission. Investigators will able to see how changes brain measurements, gene regulation and immune response relate to improvements and relapse of depressive symptoms with ketamine IV therapy. The ketamine infusion sessions will occur at a special research unit (CTRC) at UCLA.
This study will evaluate the efficacy and safety of ALKS 5461.
This study will evaluate the efficacy and safety of ALKS 5461.
The purpose of this study is to adapt depression treatment intervention for HIV patients in Cameroon. The PI will validate a depression severity measure, adapt key elements of the intervention to the Cameroon context, train nurses and physicians to carry out the intervention, and examine preliminary outcomes. Participants: Aim 1: Hospital and clinic patients, visitors, health care workers. Aim 2: No participants. Aim 3: HIV-infected patients. Procedures (methods): Survey instruments and ARV treatment.
The purpose of this study is to determine if monoamine oxidase B (MAO-B) total distribution volume (VT), after phenelzine treatment and if so to what extent.
This study will investigate the effectiveness of mindfulness-based cognitive therapy (MBCT) for mood stabilization in perinatal women (preconception, pregnant, and postpartum) with a history of mood disorders. MBCT is a short-term group psychotherapy that has shown effectiveness in preventing depressive relapse. MBCT teaches mindfulness practices and cognitive-behavioral techniques.
