Filter by:To evaluate the effectiveness of one algorithm for Major Depression Disorder (MDD) using medications available in the Brazilian Public Healthcare System (SUS), and assessment of the quality of life of these patients. A randomized pragmatic trial was conducted. An algorithm was developed for the treatment of episodes of unipolar depression episodes.
Major depressive disorder (MDD) is highly prevalent and nearly 70% of individuals with MDD do not respond to standard antidepressant therapies despite adequate dosing. An effective and well-tolerated antidepressant augmentation therapy would have important clinical and public health implications. Neuroactive steroid hormones are known to directly activate neurotransmitter receptors in the brain, and thus are potential candidates for augmentation therapies to enhance the effect of traditional antidepressants. The investigators hypothesize that administration of an allopregnanolone analog in women with treatment-resistant depression will improve depressive symptoms.
The purpose of this study is to better understand how low-level light therapy (LLLT) can be used to augment the antidepressant effects of Deprexis, an internet-based treatment program for depression, for participants with current major depressive disorder. The researchers will administer active and placebo LLLT to the right forehead of participants who show an improvement of at least 10% in depressive symptoms from baseline after two weeks of Deprexis treatment. Hypothesis: Participants who receive active LLLT will show a greater reduction of depressive symptoms than participants who receive placebo LLLT.
Transcranial Direct Current Stimulation (tDCS) is a novel non-invasive brain stimulation treatment that is effective with no significant side effects. It can potentially be self-administered by patients in their own homes with remote monitoring, substantially reducing treatment costs and increasing accessibility, including to remote areas. This study will evaluate the feasibility and efficacy of home-administered tDCS treatment for depression.
Project:EVO is a video-game based intervention that targets neural networks associated with cognitive control. The same networks have been implicated in poor treatment response in middle and older aged adults suffering from major depression. Related work has demonstrated that healthy older adults show significant improvement in cognitive control. In a very small sample of older adults suffering from depression (n=12), we found similar improvements in selective attention and working memory after 4 weeks of intervention, along with improvements in mood comparable to participants receiving an evidence-based psychotherapy. The intent of this proposal is to first determine if at least 2/3 of participants who use Project:EVO for four weeks demonstrate significant improvements in the function of these neural networks, and if improvements are observed, to conduct a second study to see if changes in neural network functions are associated with changes in mood. If we show that Project:EVO improves neural function and mood to a greater degree than a placebo cognitive training game, we will be in a position to move onto the next phase of study, which is to demonstrate the intervention's efficacy in a much larger sample of adults with depression.
The main goals of antidepressant treatments are to achieve remission of depressive episodes and prevent recurrences. However, clinical trials designed to approve antidepressants targets a response rate of at least 50%, which is considered partially effective. Therefore, there is a need for new treatment strategies, including augmentation with other substances such as lithium. This research aims to verify through a pilot study, the effect of selenium as an augmentation treatment for sertraline-resistant major depression. This clinical trial was designed to be a randomized, placebo-controlled, double-blind trial evaluating the effect of selenium or placebo in subjects diagnosed with major depression who have not responded to treatment with sertraline
The primary objective of this study is to determine the effectiveness of serial infusions of intravenous (IV) ketamine in adults with treatment resistant depression (TRD).
This study is a randomized controlled trial comparing an integrated treatment, Behavioral Activation + Cognitive Processing Therapy (BA + CPT), to CPT alone among active-duty service members with posttraumatic stress disorder (PTSD) and comorbid major depressive disorder (MDD). Participants will complete assessor-administered and self-report measures at pre- and post-treatment assessments, as well as a 3-month follow-up. Additionally, participants will complete self-report measures of PTSD and MDD symptoms at each therapy session.
Major depression is the leading cause of disability in the United States and is a major contributor to suicide, a leading cause of premature death. The majority of individuals with depression do not receive adequate pharmacologic or psychotherapeutic treatment due to difficulty accessing services or stopping treatment due to side effects, non-response, or the stigma associated with attending mental health clinic visits. Mobile health information technology services, such as text messaging, have the potential to provide effective self-management support for depression to nearly every adult in the US with depression. Guided self-help via text messaging has been shown to be effective for improving a range of health behaviors as well as symptoms of depression. However, previously studied depression text messaging services have not utilized the breadth of psychotherapeutic techniques shown to be effective for depression nor have they attempted to tailor the psychotherapeutic content to the individual in order to improve acceptability and outcomes. Advanced artificial intelligence methods (e.g., reinforcement learning) offers the capability to weed out ineffective messages and to target messages to individuals in order to substantially improve program effectiveness. This pilot study is the first step in towards developing an artificially intelligent text message service for depression. The specific aims of the study are to: 1) demonstrate the feasibility of recruiting and enrolling participants from the general population of US adults and delivering a text-messaging intervention for depression, 2) determine whether there are differences in the perceived helpfulness of messages derived from different psychotherapeutic treatment modalities, and whether these differences are moderated by participant characteristics (e.g., age, gender, depression symptom severity), 3) determine whether messages derived from different psychotherapeutic treatment modalities or their perceived helpfulness are associated with changes in depression symptoms, and whether these relationships are moderated by participant characteristics.
