Filter by:Studies exploring the efficacy of repetitive transcranial magnetic stimulation (rTMS) as a treatment for refractory major depressive disorder (MDD) have shown significant promise. Despite this, several questions regarding the treatment parameters needed to optimize efficacy remain. Moreover, there is also a lack of clear understanding as to the therapeutic mechanisms involved. For example, several lines of evidence suggest that patients with MDD have deficits in cortical inhibition (CI) and that these deficits are key to understanding the pathophysiology of this disorder. With this study, we seek to confirm the therapeutic potential of an acute course of rTMS for treatment-refractory MDD in a large sample of patients. In addition, we will strive to clarify the neurophysiological mechanisms through which rTMS exerts its therapeutic effects, using both TMS and electroencephalography/event related brain potential (EEG/ERP) measures of neurophysiological activity. Moreover, in this study, we intend to investigate the efficacy of a maintenance course of rTMS in an effort to prevent symptom recurrence.
We hypothesize that AndroGel may offer some relief to subjects with low or borderline testosterone levels who suffer from depression and have failed to respond to a trial of a standard antidepressant. During this nine week, outpatient, double-blind study, male subjects between the ages of 30 and 65 years with treatment-refractory depression and low or borderline low testosterone levels will be treated with either AndroGel or placebo. Following this nine week, double-blind phase, eligible subjects will have the option to continue into a six month, open-label phase during which time all subjects will receive the AndroGel patch.
We investigate whether the add-on specific antitoxoplasmatic medication has positive effects in individuals with schizophrenia or major depression seropositive for Toxoplasma gondii (TG) infection. As TG modulates neurotransmitter metabolism affecting serotonin and dopamine we hypothesize that this chronic persistent infection might play a role for depressive and psychotic symptomatology. Therefore, on the basis of an ex juvantibus approach, specific anti TG medication might further improve psychiatric symptomatology in affected patients. This is investigated in a double-blind, placebo-controlled, randomized treatment trial.
The primary objective is to compare the antidepressant efficacy, safety, and tolerability of DVS SR versus placebo in subjects with Major Depressive Disorder. Additional objectives include testing both general and functional quality-of-life outcomes and satisfaction with therapy reported by the subject.
Major Depressive Disorder (MDD) is a serious illness associated with considerable morbidity, risk of suicide and adverse social consequences (Montgomery et al., 1994a). Cognitive impairment is one of the three major symptom areas of MDD. Specifically, memory impairment and concerns are one of the most commonly reported complaints in MDD. While antidepressant (AD) treatments vary a great deal in their propensity to cause cognitive impairment, there remains a paucity of empirical evidence on the effects of AD treatment on neuropsychological indices of memory functioning in non-geriatric depressed individuals. Hence, comparative effects of various AD drugs on memory functioning remain unclear.The aim of this study is to evaluate multiple aspects of memory functioning (short-term, working memory, verbal, non-verbal, spatial and prospective memory) of MDD patients before and after 8 weeks of antidepressant treatment with bupropion XL or escitalopram.
Despite many available treatments, there are patients with major depression who remain treatment refractory and chronically disabled. For these severely ill patients, several neurosurgical procedures are available where brain lesions are made that interrupt white matter tracts linking orbital frontal cortex to the striatum, resulting in significant therapeutic benefit for many patients. In this study, we will test the safety and efficacy of Deep Brain Stimulation (DBS)--a reversible method used to modulate brain activity--as an alternative to the standard subcaudate tractotomy (SCT). The physiological consequences of this procedure will be mapped longitudinally using positron emission tomography (PET) measures of brain glucose metabolism. Patients will be clinically monitored for 1 year with longitudinal psychiatric, neurological, neurosurgical, neuropsychological and PET imaging examinations to assess treatment efficacy and side effects.
The main purpose of this study is to correlate brain testing with treatment outcome.
Depressed patients will have hearing tests and then be treated with up to three treatments (i.e., Fluoxetine, Imipramine) until remitted, to see whether test results predict specific outcomes.
Relatively drug naive patients will receive two antidepressant medications as initial treatment.
The proposed research aims to compare the onset of action and the efficacy of fludrocortisone, a mineralocorticoid receptor agonist vs. spironolactone, a mineralocorticoid antagonist, vs. placebo as augmentation to a selective serotonin reuptake inhibitor (SSRI) in 65 inpatients with severe depression. The study will also explore the utility of the hypothalamic-pituitary-adrenal (HPA) axis in predicting treatment response. The study will be a 5-week randomized and double-blind trial of fludrocortisone vs. spironolactone vs. placebo during three years.
