Aripiprazole Augmentation Therapy in Treatment-resistant Depression

Therapy-resistant Depression

20 therapy-refractory patients with major depression will be treated for 3 weeks with Aripiprazole 10 mg/d. Effectivity will be assessed using a pre-post comparison of different psychopathological rating scales and patient adherence.

ECT vs. Esketamine

Treatment Resistant DepressionMajor Depressive Disorder

Treatment-resistant depression (TRD) is a common cause of disability and one of the most common psychiatric disorders worldwide. Electroconvulsive therapy (ECT) is currently the most effective treatment for TRD. Recent developments showed esketamine to be a rapid-acting and effective antidepressant drug and it has been hailed as a breakthrough in treating TRD. Common treatment algorithms for TRD list ECT as a treatment option, but esketamine has not yet found its exact position in those algorithms. To the investigators' knowledge, a longitudinal, randomized controlled trial comparing the efficacy of ECT and intranasal esketamine in TRD patients has not been conducted. Furthermore, the investigators intend to measure effects of ECT and intranasal esketamine on brain connectivity and structure, using functional magnetic resonance imaging (fMRI). In this study, inpatients with TRD at the University Hospital for Psychiatry I, Medical University Innsbruck, will be randomized to ECT or intranasal esketamine. Short- and medium-term treatment effects on functional and structural connectivity in the brain will be determined using fMRI.

Characterizing Dopamine Receptor Binding in Treatment Resistant Depression

Treatment Resistant Depression

It is estimated that 30% of individuals with Major Depressive Disorder (MDD) fail to respond to conventional antidepressant medication which accounts for over 1 million Canadians in their lifetime. Treatment resistant depression (TRD) patients also have greater psychiatric and medical comorbidity, poorer quality of life and increased suicidal ideation. Yet, there are few treatment strategies available to target TRD and there is a significant lack of evidence about how TRD differs from treatment-responsive depression. This proposal represents the first study to elucidate the neurobiology of TRD with a focus on dopamine receptor function throughout the brain, in order to inform treatment development and clinical characterization of TRD.The ultimate goal of this unique study is to characterize striatal and extrastriatal dopamine D2 and D3 receptor binding potential in patients with TRD, non-resistant MDD and healthy controls. The primary hypothesis is that TRD patients will exhibit greater D2/D3 receptor binding potential compared to non-TRD patients in the following regions of interest: dorsolateral prefrontal cortex, orbitofrontal cortex, and ventral striatum. Secondarily, non-TRD patients will also demonstrate increased binding potential compared to healthy controls in the same brain regions. Whole brain analyses will allow us to take an exploratory approach to other brain regions that may differentiate TRD from non-TRD patients. Participants will be assessed at St. Michael's Hospital (SMH) and the Centre for Addiction and Mental Health (CAMH), which are within a 10 minute driving distance of each other. There will be 3 study visits following written informed consent. Eligibility will be confirmed at a screening visit at SMH where demographic information, including age, sex, education, and medication history will be obtained, as well as the administration of a structured Mini-International Neuropsychiatric Interview (MINI) for Diagnostic and Statistical Manual of Mental Disorders (DSM-5) Axis I diagnoses (Sheehan et al, 2015), and an HRSD-17. Within two weeks of the screening visit, participants will undergo a structural magnetic resonance imaging (MRI) scan at SMH prior to the positron-emission tomography (PET) scan at CAMH. The order of the PHNO scans will be counterbalanced.

Three Dosing Regimens of Dextromethorphan (DXM) Reportedly Used in Major Depressive Disorder

MDDTreatment Resistant Depression2 more

This is an open-label dosing pilot study of 15 patients aged 18-50 years of age with diagnoses of Major Depressive Disorder (MDD) randomized to 1 of 3 treatment arms. The study will consist of a screening evaluation performed within the course of 2 weeks, followed by an active treatment period of 28 days where treatment arm 1 will take a supervised dose of 300mg DXM every 14 days for 28 days, treatment arm 2 will take the FDA approved maximum daily ingestion for cough (60mg DXM) daily for 28 days, and treatment arm 3 will take 1 supervised dose of 300mg DXM and 60mg for the remaining 28 days. After the active treatment period, subjects will be followed for 65 days with safety and psychiatric assessments at designated timepoints.

Psychosocial Characteristics and Non-pharmacological Intervention of Patients With Treatment-resistant...

Treatment-resistant Depression

Pharmacotherapy and psychotherapy, effective management strategies for treatment-resistant depression are limited and yet to be developed. However, nursing interventions focusing on adherence enhancement, symptom reduction, and stress management may be strategic for a better disease management. This study aimed to define the rarely-studied concept of TRD under the cultural context of Taiwan and to identify new feasible and complementary treatment model from nursing perspectives. The project had established important basis on the descriptions of psychosocial features and need assessment of people with TRD over psychiatrist's validation. The findings also built up a cultural-specific non-pharmacological intervention module for effective TRD management in Taiwan. The nursing model of TRD management will further promote the development of integrative depression care in the future and complement current modalities, while providing important evidence-based information for future research and services.
