Active clinical trials for "Depressive Disorder"

The project aimed at identifying neuropsychobiological signatures of pharmacological sex-steroid hormone manipulations in healthy women as a risk model for depression. The study is a double-blind, randomized, placebo-controlled study. Investigators included 63 healthy female volunteers with regular menstrual cycles between 23 and 35 days. Participants were randomized to active Gonadotrophin-Releasing-Hormone agonist (GnRHa) (goserelin 3.6 mg implant) or placebo (saline injection) intervention, which was initiated in the mid follicular phase (i.e. cycle day 22.6 ±2.5). Sixty women completed follow-up and entered the analyses, except for a few drop outs on some domains. The following domains were addressed at baseline and at follow-up (16±3 days post intervention), (which corresponded to the early ovarian suppression phase of the biphasic hormone response to GnRHa): 1) serotonin transporter binding as imaged by 11CDASB Positron Emission Tomography (PET), 2) functional Magnetic Resonance Imaging (fMRI) emotional processing, 3) fMRI reward processing, 3) rating state fMRI (rsfMRI), 4) structural MRI, 5) Neuropsychology, 6) Psychophysiology, 7) Hypothalamus-Pituitary-Adrenal cortex (HPA)-axis dynamics, 8) Peripheral markers of immunoactive cell responses, 9) Epigenetic factors. Psychometrics in terms of self reported mental distress and interview based ratings were monitored across the intervention period to monitor potential symptoms of mental distress and psychopathology. Also ovarian hormone responses, peripheral blood markers, and side effects scores were collected across the intervention period.

The purpose of this study is to explore patterns of Brain Network Activation (BNA) changes from baseline to endpoint on 1) efficacy of core symptoms of Major Depressive Disorder (MDD) and 2) improvement of cognitive dysfunction with acute treatment with flexible dose vortioxetine in adult outpatients with MDD and subjective complaints of cognitive dysfunction.

Depression has emotional consequences, social and important business. Reaching at least 7.5% of French aged 15 to 85 years. General Practitioners are the first professional consulted in terms of frequency of consultations. Indeed, in primary care, 10 to 25% of patients with depression that General Practitioners are often alone to support and follow. But General Practitioners are faced with diagnostic difficulties facing the diagnosis of depression, because if the patient does not engage itself, no tool is validated in France to help them in their diagnosis. However, standardized questionary exist that allow to overcome this difficulty. Questionary used in other european countries. Among them, the HSCL25 scale was selected by a systematic review of literature and a RAND UCLA type of consensus procedure. This HSCL25 scale is the most efficient for the diagnosis of depression in terms of efficiency tool, reproducibility and ergonomics. However, it remains necessary to confirm its validity in terms of the French translation and in terms of efficiency.

The study aims to evaluate the effectiveness of an intervention to reduce alcohol and drug use and depression symptoms, improve functional status and promote appropriate health services utilization, in a sample of 300 adults seeking treatment for depression who also report hazardous drinking or drug use with depression.

This is a randomized, control group design of pharmacogenetic implementation in a mental health population of subjects taking anti-depressants and/or anti-psychotics with a new or current primary or secondary diagnosis of Major Depressive Disorder (MDD) or Depressive Disorder Not Otherwise Specified (DDNOS).

To evaluate the effect of visit number, patient expectation, and rater expectation of the efficacy of escitalopram treatment in fixed doses of 10 and 20mg, based on baseline severity in patients with MDD.

Purpose of the Study: (1) To classify an individual subject's ventilatory response in terms of respiratory depression to a bolus of remifentanil under normoxic and hyperoxic conditions. (2) Measurement of specific respiratory parameters to predict the opioid-induced respiratory depression (OIRD) response.

The purpose of this study is to validate the effectiveness of using an integrated mobile sensing platform to deliver large-scale data-driven interventions to patients with depression.

Mothers with symptoms suggesting clinical depression can be identified and potentially motivated to seek further care during pediatric visits for their young children. The best ways for pediatric providers to encourage mothers to seek further evaluation and treatment for their depressive symptoms are not known. The investigators plan to provisionally optimize a pediatric office-based intervention that the investigators developed to motivate mothers who may be depressed to seek further care and, thereby to improve the well-being of women from diverse backgrounds and their children.

From 40 to 60% of patients with depression experience a rapid and significant improvement of mood with one night of sleep deprivation (SD). The neural mechanisms underlying this effect have not been elucidated. Recent advances in functional neuroimaging have provided new opportunities to investigate state changes in regional brain function, along with a better understanding of the neural networks affected by depression and SD. Here we propose to study a group of N=48 antidepressant-free male and female patients with current depression symptom and N=12 healthy controls with no history of mood disorders before and after SD to provide mechanistic insight into the neural substrates underlying the antidepressant effects of SD. We hypothesize that SD-induced concurrent functional activity and connectivity changes in multiple brain networks related to different depressive symptom dimensions including emotion regulation, attention, arousal, self-referential, and reward processing will underlie the rapid and transient antidepressant effects of SD. Using an ABA design, multimodal brain imaging along with more traditional electroencephalographic (EEG) and neurobehavioral testing data will be acquired at baseline after normal sleep, during one night of total SD, and after one night of recovery sleep using a 5-day in laboratory protocol during which subjects will be continuously monitored by trained staff.
