View clinical trials related to Depressive Disorder, Major.
Filter by:The goal of this observational study is to evaluate current practices in depression treatment in psychiatric services in Stockholm, Sweden. The main questions it aims to answer are: - Are current practices consistent with local clinical guidelines in terms of standardized assessment and the treatments provided? - What are the present conditions for implementing measurement-based care in depression treatment in this setting? Data will be collected retrospectively from medical records of patients having received psychological or pharmacological treatment for depression from 2020 to 2023. Frequency of standardized assessments (not scores) using the Montgomery-Åsberg Depression Rating Scale, the Montgomery-Åsberg Depression Rating Scale-Self Assessment, and the Patient Health Questionnaire-9 is collected, together with information on patient, clinician, and treatment characteristics.
Depression is a leading cause of disability worldwide, affecting roughly 21 million adults. Repetitive Negative Thought (RNT) has been identified as a potential maintaining factor in depression, such that those who exhibit higher degrees of RNT endorse greater symptoms. Research also suggests that the Default Mode Network (DMN), responsible for self-referential processing, plays an important role in depression wherein it has been linked to RNT. In depressed individuals, this network appears to be hyper-connected, or "too connected", within itself which, in turn, is thought to promote RNT. Half of depressed individuals are treatment-resistant, creating a critical need to identify more effective interventions derived from a better mechanistic understanding of the development and maintenance of depression. Non-invasive Transcranial-Focused Ultrasound Stimulation (tFUS) is promising for the treatment of depression. tFUS directs a low-intensity (nonthermal) focused ultrasound beam that passes safely through the skull. Compared to other noninvasive neuromodulation approaches, tFUS can target deeper brain regions with high spatial precision. The present study is an exploratory non-blinded single treatment study to investigate whether tFUS targeting a major hub of the DMN, the anterior-medial prefrontal cortex, can improve depression symptoms and reduce RNT. Twenty depressed individuals with high RNT (75th percentile) will complete up to eleven ultrasound sessions targeting the anterior medial prefrontal cortex, a hub of the brain's default mode network that has been found to be hyper-connected in depression. MRI scans will be obtained before the first and after the last ultrasound sessions. Based on previous literature, it is predicted that depression interview ratings and self-report symptoms will decrease after the intervention, and also that DMN connectivity will decrease following intervention.
This study will examine the efficacy and safety of a self-guided digital therapeutic app for the adjunct treatment of Major Depressive Disorder compared to a control app in adolescents and adults.
Transcranial magnetic stimulation (TMS) is an effective treatment for depression, but clinical outcome is suboptimal, partially because investigators are missing biologically-grounded brain markers which show that TMS is modifying activity at the intended target in the brain. The goal of this proposal is to characterize the key markers of the brain's response to repeated doses of TMS with high resolution using invasive brain recordings in humans, and relate these brain markers to noninvasive recordings. These markers will improve the understanding of TMS and can be used to optimize and enhance clinical efficacy for depression and other psychiatric disorders.
Major Depressive Disorder (MDD) is a common mental health diagnosis. While there are many approaches to the treatment of MDD, current treatments of MDD often do not substantially reduce depressive symptoms among those in need of care. Prior research suggests that combining cognitive-behavioral therapy (CBT) and psychopharmacology can produce optimal treatment outcomes compared to the use of either treatment individually. Transcranial Magnetic Stimulation (TMS) is one promising brain stimulation approach used to treat MDD, especially among patients with treatment-resistant symptoms. Like psychopharmacological interventions, TMS may produce optimal treatment outcomes when paired with CBT. However, standard TMS protocols are time-intensive, typically requiring daily doctor visits for one hour of six to eight weeks. Therefore, an internet-delivered CBT protocol may augment the effects of TMS without substantially increasing patient burden. To that end, the present study assesses if a combined TMS and internet-delivered CBT protocol may produce superior treatment outcomes compared with TMS alone.
The investigators propose to use low-intensity transcranial focused ultrasound (LIFU), a novel neuromodulation method, to probe the causal involvement of individually defined components of an anteromedial brain circuit in the processing of self-referential thoughts, and the production of repetitive negative thinking (RNT), a prominent transdiagnostic manifestation with adverse clinical consequences. The investigators hypothesize that real vs. sham low-intensity sonication of individually-defined anteromedial structures connecting medial orbitofrontal and anterior cingulate cortices with ventral striatum and anterior thalamus will show reduced initiation or maintenance of RNT as measured by (1) Brief State Rumination Inventory (BSRI) scores and distress associated to repetitive negative thoughts, and (2) improvement of the affective valence associated to self-referential adjectives, and that these changes will be associated with decreased connectivity between structures mentioned above. The present early feasibility study is an initial step that aims to determine its feasibility and help with the planning of a larger study addressed at actual hypothesis testing.
The purpose of this study is to assess the effects of simultaneous administration of oral aspirin and oral ketamine as a therapeutic for those with Treatment Resistant Depression.
The purpose of this study is to assess which antidepressants work the best in older adults who have treatment-resistant depression (TRD), and to test whether treatment-resistant late life depression is associated with declines in memory and attention and brain structure and function.
Public safety personnel (PSP; e.g., border services personnel, correctional workers, firefighters, paramedics, police, public safety communicators) are frequently exposed to potentially psychologically traumatic events. Such events contribute to substantial and growing challenges from posttraumatic stress injuries (PTSIs), including but not limited to posttraumatic stress disorder. The PSP PTSI Study has been designed to evaluate an evidence-informed, proactive system of mental health assessment and training among Royal Canadian Mounted Police (www.rcmpstudy.ca) for delivery among diverse PSP (i.e., firefighters, municipal police, paramedics, public safety communicators). The training is based on the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders, adapted for PSP, and named Emotional Resilience Skills Training (ERST). The subsequent PSP PTSI Study results are expected to benefit the mental health of all participants and, ultimately, all PSP.
This is a single-arm, open-label Phase 2 study to assess the safety, tolerability, pharmacokinetics (PK), and activity of ANC-501 oral capsules as adjunctive treatment in subjects diagnosed with major depressive disorder (MDD)
