Filter by:This study evaluates the vestibular activity in major depression patients and healthy controls using the rotatory test and electronystagmography.
The proposed study is to evaluate the safety and initial efficacy of MRgFUS for patients with treatment-refractory Major Depression. This study is designed as a prospective, single arm, nonrandomized study. Assessments will be made before and after MRgFUS for adverse events related to treatment, for clinical symptom relief, and quality of life (QoL). The target in the brain chosen for ablation will be the anterior limb of the internal capsule (i.e 'capsulotomy').
Major depressive disorder (MDD) is a complex and multi-factorial disorder. Most of the current antidepressants are based upon the monoamine hypothesis which cannot fully explain the etiology of depression. Many elderly patients have significant side effects after treatment with antidepressants which hamper the motivation for treatment and medication adherence. NMDA hypofunction has been implicated in the pathophysiology of depression. MDD in the elderly is often associated with cognitive deficits which are not necessarily recovered by current antidepressants. The NMDA receptor regulates synaptic plasticity, memory, and cognition. In our previous studies, cognitive improvement has been observed with treatment of NMDA enhancers. Therefore, this study will examine the efficacy and safety as well as cognitive function improvement of NMDAE in the treatment of MDD in the elderly by comparing with sertraline (a selective serotonin reuptake inhibitor [SSRI]) and placebo. The investigator will enroll elderly patients with MDD for an 8-week treatment. All patients will be randomly assigned into three groups: NMDAE, sertraline, or placebo. The investigator will biweekly measure clinical performances. Cognitive functions will be assessed at baseline and at endpoint of treatment by a battery of tests. The investigator hypothesize that NMDAE can safely yield better efficacy than placebo and sertraline for elderly patients with MDD.
The investigators are examining whether difficulties with cognitive control (i.e., the ability to stop one's thought process and shift attention) is a common problem across three types of repetitive, negative thinking: obsessions (as seen in obsessive compulsive disorder, OCD), worries (as seen in generalized anxiety disorder, GAD), and ruminations (as seen in major depressive disorder, MDD).
The aim of this study is to determine if altering the pattern of one's sleep and having light therapy can speed up the treatment of depression. In the UK, the large majority of patients with depression in the NHS are treated in the community, and one of the major objectives of the study one is to determine if this therapy is a practical treatment in the community. We will be comparing two treatments: 1. Sleep Therapy and a Light Box: Participants will be given information and advice on how to get a good night's sleep. Participants will be given a light box to use in the morning for 1 week. Treatment with a light box will last 30 minutes when a person gets up. Participants may continue to have any treatment as usual (for example medication or talking therapies). 2. Wake therapy and a Light Box: Participants will be helped to change the pattern of sleep by depriving participants of sleep for one night. Participants will go bed at 5pm on the following day for 8 hours and get up at 1am. Participants' sleep will then be advanced by 2 hours each night for the next three nights. Participants will be also given a light box to use in the morning for 1 week. Treatment with a light box will last 30 minutes when participants get up. Participants may continue to have any treatment as usual (for example medication or talking therapies).
The objective of this study is to evaluate the safety and efficacy of Hypidone Hydrochloride tablets in treatment of patients with major depressive disorder (MDD) by evaluating the change of MADRS total score from baseline to week 6.
The purpose of this clinical trial is to determine the safety and efficacy of scopolamine utilized in conjunction with naltrexone for the treatment of major depression.
The purpose of this study is to examine the effects of different treatment locations using repetitive transcranial magnetic stimulation (rTMS) to treat major depressive disorder.
The purpose of this study is to explore if the magnitude of treatment effect (JNJ-42847922; placebo) on symptoms of depression (as measured by Hamilton rating scale for depression-17 [HDRS17], Sleep item-adjusted HDRS17, Anxiety/somatization factor score and the 6-item subscale from HDRS17 [HAM-D6]) differs across different levels of hyper-arousal status (characterized by Sleep parameters, ruminative response scale [RRS], Sleep and Worry visual analogue scale [VAS], quantitative electro-encephalography [qEEG], heart rate variability [HRV] and others).
The proposed study will assess the combined effect of perampanel and ketamine on the anti-depressant response in individuals with treatment resistant depression. The purpose of this study is to test the hypothesis that stimulation of Alpha-Amino-3-Hydroxy-5-Methyl-4- Isoxazole Propionic Acid receptors (AMPAR) is critical to the anti-depressant response of ketamine.
