Filter by:Background: People with TRD are often helped by electroconvulsive therapy (ECT). But ECT can affect memory and thinking. Researchers want to study a treatment called TEST that uses less electricity. Objective: To study the safety and feasibility of TEST and assess its antidepressant effects. Eligibility: Adults aged 25-64 with major depression that has not been relieved by current treatments. Design: Participants will be admitted to the NIH Clinical Center for 5 18 weeks over 2 3 treatment phases. Their medications may be adjusted. Participants will be interviewed about their depression, side effects, and other treatments they are receiving. They will complete questionnaires. They will give blood and urine samples. Their brain waves and heart rhythm will be recorded. They will take tests of memory, attention, mental functioning, and thinking. Participants will have magnetic resonance imaging (MRI) scans of the head and brain. They will lie on a table that slides in and out of the scanner. Pictures of brain chemicals will also be taken. They may complete tasks during the MRI. Participants will receive TEST and/or sham treatments. They may receive optional ECT. An intravenous catheter will be placed in an arm vein to receive general anesthesia. Two electrodes will be placed on the front of their head. An electric current will be passed from the ECT machine through the electrodes. For sham treatments, they will not receive the electric current. Their breathing, heart rate, brain function, blood pressure, and body movements will be measured. Participants will have 7 follow-up visits over 6 months. Visits can be done via telehealth. Participation will last for up to 42 weeks.
The purpose of this antidepressant study is to determine the efficacy of vortioxetine on depression and cognition in 80 women with breast cancer, and to elucidate inflammatory-mediated mechanisms by which depression and its treatment influence cancer outcome. Our hypothesis is that effective vortioxetine antidepressant therapy in depressed women with breast cancer will attenuate increased intermediate endpoints of inflammation that contribute to the pathogenesis of depression, cognitive impairment, and cancer progression
50 Right-handed antidepressant-free unipolar depressed patients (age 18-65 years) will be treated with in total 20 Theta burst sessions; these will be spread over 4 days. On each stimulation day, a given patient shall receive 5 sessions with a between session delay of 10 to 15 minutes. Patients will be selected using the structured Mini-International Neuropsychiatric Interview (MINI). All will be at least stage I treatment resistant. Because concomitant antidepressant treatment can confound outcome results, all patients will go through a medication washout before entering the study and they will be free from any antidepressant, neuroleptic and mood stabilizer for at least two weeks before entering the treatment protocol. Only habitual benzodiazepine agents will be allowed. All patients will be closely matched for gender and age with 50 never-depressed medication-free healthy volunteers. Only baseline measurements will be collected: no volunteer will undergo the treatment. We expect that real Theta burst treatment and not sham will result in a significant and clinical meaningful response.
