Analysis of recent studies show that researchers find it hard to distinguish between Late Onset Depression, a first diagnosed major depressive episode which occurs at old age, and Early Onset Depression, a depressive episode at old age with a history of previous episodes. Since current data, about the phenomenology and etiology of Late Onset Depression, lake conicity it is unclear whether this phenomena should be considered as a distinct subtype of depression. Nevertheless, the wide spread assumption is that Late Onset Depression has a stronger correlation with brain damage and environmental risk factors such as the common losses at old age and weaker correlation with family history and genetics when compared to Early Onset. Although many researchers consider brain damage to have the main contribution to the emerge of Late Onset Depression, the fact that depression has a negative effect on one's health supports the claim that it might be the result and not the rick factor. Since Late Onset Depression correlates with the common losses at old age, the investigators propose that an existential approach that deals with one's meaning, freedom, responsibly and death, might be more appropriate. Thus, the investigators ask how do older adults experience depression which they face for the first time in old age? Current study will seek to understand older adults' experience of Late Onset depression through existential paradigm by using a semi constructed interview.
Major depressive disorder (MDD) is highly prevalent and nearly 70% of individuals with MDD do not respond to standard antidepressant therapies despite adequate dosing. An effective and well-tolerated antidepressant augmentation therapy would have important clinical and public health implications. Neuroactive steroid hormones are known to directly activate neurotransmitter receptors in the brain, and thus are potential candidates for augmentation therapies to enhance the effect of traditional antidepressants. Investigators hypothesize that administration of an allopregnanolone analog in women with treatment-resistant depression will improve depressive symptoms.
Open label placebo treatment has been tried for irritable bowel syndrome (Kaptchuk et al, 2010), where three weeks of open label placebo proved superior to a wait-listed control group. Another pilot study demonstrated efficacy in treating children suffering from ADHD with open label placebo treatment (Sandler & Bodfish, 2007). Recent work has shown that placebo openly given can have significant analgesic effects for acute migraines (Kam-Hansen et al, 2014) and for experimentally-induced pain (Schafer at al, 2015). A preliminary attempt to treat depression with open label placebo proved the feasibility of such a study, but was too small and brief for conclusive results (Kelley et al, 2012). We provide here the protocol for a study to assess the effect of open label placebo treatment for depression.
This is a phase II, open-label clinical trial. This clinical trial has as primary objective to evaluate changes in EEG of a Trigeminal Nerve Stimulation (TNS) treatment protocol for elderly patients with moderate / severe depressive episode.
The purpose of this study is to explore patterns of BNA changes from baseline to endpoint on 1) efficacy of core MDD symptoms and, 2) improvement of cognitive dysfunction with acute treatment of flexible dose vortioxetine in adult outpatients with MDD and subjective complaints of cognitive dysfunction.
Double-Blind, Placebo-Controlled, Multicenter Study of Efficacy and Safety
This research is to study the effectiveness of cognitive behavioral therapy-CBT and Psychotherapy by trained buddhist monks. There are generally accepted that both cognitive and Buddhist concepts are related. This randomized controlled trial is to study the elderly participants who suffer major depressive disorder according to DSM-IV. The subjects will be divided into two groups. The experimental group will receive 12 sessions of CBT 2 times per week for 6 weeks in addition to usual treatment. The control group will receive treatment as usual and general conversation (non-CBT) with monks. Pretreatment factors (such as attachment style, interpersonal factors) of both therapist monks and patient participants will be studied.
Aim 1 is to study prevalence and 1 year incidence of metabolic syndrome in major depressive disorder and factors correlation. Aim 2 is to study prevalence and 1 year incidence of thyroid dysfunction in major depressive disorder and factors correlation.
Transcranial direct current stimulation (tDCS) is a noninvasive method to activate or de-activate neurons in superficial regions of the brain through the induction of weak electric currents in the brain tissue delivered by two scalp electrodes. Initial studies have shown tDCS to be effective for treating major depressive disorder (MDD), although there are negative trials in the specialized literature. One reason for these discrepant results might be that the duration of tDCS treatment in clinical trials to date (up to 2 weeks) is still insufficient to produce consistent clinical improvements. Thus, we intend to assess, in a sample of outpatients with MDD, whether a 3-week adjunctive course of active tDCS over the left dorsolateral prefrontal cortex is associated with a significant clinical improvement when compared to sham tDCS. The investigators hypothesize that subjects receiving active tDCS will present with significantly higher response and remission rates at weeks 3.
