Transcranial Direct Current Stimulation (tDCS) Therapy in Major Depression
Major Depressive DisorderNoninvasive transcranial direct current stimulation (tDCS) is a low-intensity neuromodulation technique of minimal risk that has been used as an experimental procedure for reducing depressive symptoms and symptoms of other brain disorders. Though tDCS applied to prefrontal brain areas is shown to reduce symptoms in some people with major depressive disorder (MDD), the extent of antidepressant response often differs. Methods that map current flow directly in the brain while a person is receiving tDCS and that determine how functional neuroimaging signal changes after a series of tDCS sessions may help us understand how tDCS works, how it can be optimized, and if it can be used as an effective antidepressant. Investigators will address these questions in a two-part randomized double blind exploratory clinical trial. For this part of the study, investigators will determine relationships between target engagement and clinical outcomes (mood) and functional sub-constructs of cognitive control and emotion negativity bias, and whether imaging markers at baseline predict changes in antidepressant response. One hundred people with depression (50 in each group) will be randomized to receive either HD-tDCS or sham-tDCS for a total of 12 sessions each lasting 20 minutes occurring on consecutive weekdays. At the first and last session, subjects will receive 20-30 minutes of active or sham HD-tDCS in the MRI scanner, which will allow investigators to map tDCS currents, and track changes in regional cerebral blood flow (rCBF) pre-to- post treatment using completely non-invasive methods. At the first and last session and mid-way through the trial, participants will also complete a series of clinical ratings and neurocognitive tests.

Dopaminergic Dysfunction in Late-Life Depression
Late Life DepressionCognitive Decline4 moreLate-Life Depression (LLD), or depression in older adults, often presents with motivational deficits, deficits in performance in cognitive domains including processing speed and executive dysfunction, and mobility impairments. This triad of findings implicate dopaminergic dysfunction as a core pathophysiologic feature in depression, and may contribute to cognitive decline and motor disability. Normal aging results in brain-wide dopamine declines, decreased D1/D2 receptor density, and loss of dopamine transporters. Although brain changes associated with depression and aging converge on dopamine circuits, the specific disturbances in LLD and how responsive the system is to modulation remain unclear. In this study, investigators are testing integrative model that aging, in concert with pro-inflammatory shifts, decreases dopamine signaling. These signally changes affects behaviors supported by these circuits, in the context of age-associated cortical atrophy and ischemic microvascular changes, resulting in variable LLD phenotypes. Investigators propose a primary pathway where dopaminergic dysfunction in depressed elders contributes to slowed processing speed and mobility impairments that increase the effort cost associated with voluntary behavior. The central hypothesis of this study is that late-life depression is characterized by dysfunction in the dopamine system and, by enhancing dopamine functioning in the brain. By improving cognitive and motor slowing, administration of carbidopa/levodopa (L-DOPA) will improve depressive symptoms.
Brexpiprazole Treatment for Bipolar I Depression
Bipolar DepressionBipolar disorder (BD) is a frequent and lifelong recurrent mood disorder with treatment-resistant depressive episodes. Importantly, depressive symptoms and cognitive decline are major determinants of functionality and quality of life in this clinical population. There is robust evidence that individuals with BD have neurocognitive deficits (especially in memory and executive functioning domains) compared to the healthy population. These deficits are present in all mood states and can greatly affect patients' functional capacity, often more so than mood symptoms themselves. Many pharmacological treatments for BD adversely affect cognition, and those that are beneficial can be difficult to use. There is thus a pressing need to identify a safe, easy-to-use medication that can target both cognitive deficits and depressive symptoms in BD. It is expected that Brexpiprazole adjunctive treatment will be efficacious in treating BD type I and type II depression by improving mood symptoms, as well as cognitive capacity and global functioning, and that such changes will be accompanied by concurrent alterations in associated brain structures.
Mental Health Assessment and Prescribing by Alberta Pharmacists

Major Depressive DisorderWe propose to carry out a treatment experiment in which we evaluate the extent to which randomizing primary care clinicians have access to remote internet-based Cognitive Behavior Therapy (eCBT) in rural West Virginia (WV) and Kentucky (KY) will help improve treatment of patients with Major Depressive Disorder (MDD). WV and KY are two of the most rural states in America and mental health treatment resources are low; especially in rural parts of the state.

MDDThe MOOD study will evaluate the safety and efficacy of a noninvasive, self-administered external Combined Occipital and Trigeminal Neurostimulation (eCOT-NS) treatment for Major Depressive Disorder (Relivion®DP). This is a prospective, multi-center, 2-arm randomized, double-blind, parallel-group, sham-controlled study. The study will include the following stages: Screening, Eligibility evaluation and Randomization to Relivion®DP vs. Sham control (1:1 randomization) (Baseline - Day 0). Daily treatment period: Active/Sham (Group A/B) treatment protocol (Baseline to end of 8 weeks). Open label phase: Active treatment period of additional 8 weeks. After completion of the open label period the subject's participation in the study will be over.
Simvastatin add-on Treatment to Standard Antidepressant Therapy in Patients With Comorbid Obesity...
Depressive DisorderMajor1 moreMajor depressive disorder (MDD) and obesity are major contributors to impaired health worldwide. Statins are among the most prescribed medications with well-established safety and efficacy. Statins are recommended in primary prevention of cardiovascular disease, which has been linked to both MDD and obesity. Moreover, statins are promising candidates to treat MDD because a meta-analysis of pilot randomized controlled trials has found antidepressive effects of statins as adjunct therapy to antidepressants. However, no study so far has tested the antidepressive potential of statins in patients with MDD and comorbid obesity. Therefore, we hypothesize that Simvastatin add-on to standard antidepressant Escitalopram will improve depression to a greater extent than add-on placebo in patients with comorbid obesity and major depression. We will randomize 160 obese MDD patients at 8 recruiting centers to either Simvastatin or placebo as add-on to Escitalopram for 12 weeks. If successful, our trial would have immediate impact on clinical practice given the fact that Simvastatin and Escitalopram are available as inexpensive generic drugs with established safety.
Improving Attentional and Cognitive Control in the Psychological Treatment of Intrusive Thoughts...
Obsessive-Compulsive DisorderGeneralized Anxiety Disorder1 moreThe investigators are conducting this study to learn more about the cognitive and attentional processes among individuals with three types of repetitive negative thinking (RNT): mental rituals (as seen in obsessive compulsive disorder, OCD), worries (as seen in generalized anxiety disorder, GAD), and ruminations (as seen in major depressive disorder, MDD). Specifically, the investigators are studying whether psychological treatment can help people with RNT who have trouble stopping unwanted thoughts and shifting their attention.
Engaging Black Youth in Depression and Suicide Prevention Treatment Within Urban Schools
DepressionSuicidal IdeationCompleting evidence-based treatments for depression has been shown to be particularly problematic for Black adolescents. If Black adolescents' depression treatment needs are to be met, the engagement challenges and the factors that lessen the success of treatment in the "real world" must be addressed. The investigators will examine the effectiveness of the Making Connections Intervention (MCI) and investigate key mediators of both engagement and response to treatment for depression. The MCI is a 1-2 session, evidence-based intervention designed to improve engagement, perceived relevance, and treatment satisfaction among depressed, Black adolescents. The study also uses tailored outreach strategies for adolescents and parents by including innovative digital content such as a web page/app along with other digital products. This study will address an important public health issue: How best to connect Black adolescents with depression to treatment in clinically meaningful ways, and how best to deliver evidence-based treatment to them through school-based services.
