NCT ID: NCT03313674 Recruiting - Clinical trials for Major Depressive Disorder

Investigation of Seasonal Variations of Brain Structure and Connectivity in SAD

Start date: November 1, 2017
Phase: N/A
Study type: Interventional

Seasonal Affective Disorder (SAD) is a subtype of Major Depressive Disorder, characterized by a recurrent temporal relationship between the season of year, the onset and the remission of a major depressive episode. Estimates of the annual prevalence state that 1-6% of the population will develop SAD with the larger prevalences found at greater extremes in latitude. SAD is most likely triggered by the shortening photoperiod experienced in the winter months leading to a deterioration of mood. Recent cross-sectional neuroimaging studies have found cellular and neurotransmitter changes in response to seasonality, ultimately having an impact on the affect of patients. Conversly, this study aims to investigate the changes in neurocircuitry related to depression and euthymic states. Patients with SAD offer a unique ability to study these changes since they have predictable triggers for the onset of depression (i.e. the winter months) and remission (i.e. the summer months).

NCT ID: NCT03311529 Recruiting - Anxiety Disorders Clinical Trials

Effectiveness and Underlying Mechanisms of Applied Relaxation as Indicated Preventive Intervention

Start date: September 1, 2016
Phase: N/A
Study type: Interventional

As mental disorders constitute a core health care challenge of the 21th century, increased research efforts on preventive interventions are indispensable. In the field of clinical psychology, indicated preventive interventions targeted to those with initial symptomatology appear particularly promising. Applied relaxation (AR) is a well-established intervention technique proven to effectively reduce tension/distress, anxiety and depressive symptoms in the context of treatment of a wide variety of manifest mental disorders as well as somatic illnesses. However, it has not been studied so far whether AR as indicated preventive intervention in subjects with initial symptomatology but no full-threshold mental disorder yet is capable to prevent a further symptom escalation. This randomized controlled trial in subjects with elevated tension/distress, anxiety or depressive symptomatology aims to investigate whether an AR intervention (10 sessions à 60 min) can (a) effectively reduce present psychopathological symptoms as well as (b) prevent a further symptom progression to full-threshold DSM-5 mental disorders. Putative mediators (physiological, emotional, cognitive and behavioral changes including heart rate and heart rate variability, hair and salivary cortisol secretion, affectivity, self-efficacy, internal locus of control and cognitive / behavioral coping) and moderators (sex, age, symptom severity at baseline and homework adherence during the intervention course) of the intervention/preventive efficacy will be additionally studied. Predictor and outcome measures will be assessed both conventionally (via personal interview, questionnaires and physiological measures during the respective main assessment) and with ecological momentary assessments (EMA, applied via smart phone over a 1-week interval following the respective main assessment) in everyday life.

NCT ID: NCT03310827 Recruiting - Depression Clinical Trials

DNA-based Dietary Advice for Adults With Depressive Disorders

Start date: September 19, 2017
Phase: N/A
Study type: Interventional

To evaluate the feasibility of nutrigenomics as an intervention for mental health conditions, a phase I randomized controlled trial of 42 adults (19 to 50 years) with depressive disorders using a 2:1 ratio of group selection (28 in the intervention {I} group and 14 in the control {C} group) is proposed. Participants with a confirmed depressive disorder will be recruited from two local mental health clinics. Those randomized into the I group will do the gene testing and be provided personalized DNA-based dietary advice from a registered dietitian; those in the C group will also receive testing but be given general dietary advice by a registered dietitian. Pre- and post-intervention comparisons (3 and 6 weeks after a personalized nutrition plan is given) will be analyzed based on records of dietary intakes (i.e., 3 day food records and food frequency questionnaire) and psychiatric functioning (e.g., Quick Inventory of Depressive Symptomology, Hospital Anxiety and Depression Scale, Outcome Questionnaire - OQ-45). In addition, measures that track physical activity, sedentary behavior, and sleep quality as well as sociodemographics will be included as covariates. After the intervention study is completed, in-depth focus group interviews will be conducted. Participants will be asked questions that will elicit their perceptions of the nutrigenomics test and the personalized dietary advice provided as well as the behavioural response to disclosure of genetic information.

Mindfulness Training in U.S. Army Cohorts

Start date: October 9, 2017
Phase: N/A
Study type: Interventional

This project aims to contextualize delivery of mindfulness training to U.S. Army personnel, evaluate its effectiveness on measures of executive functions and psychological well-being, and determine best practices for its delivery.

NCT ID: NCT03309163 Recruiting - Caesarean Section Clinical Trials

Effect of Tramadol in Prevention of Postpartum Depression

Start date: October 9, 2017
Phase: Phase 4
Study type: Interventional

The incidence of postpartum depression in Europe and the United States is about 10%, while in China the incidence rate of 15.7-39.8%. Postpartum depression is one of the most common diseases of perinatal distress, but the current research of high-quality prevention and treatment of postpartum depression is still very lack. The study suggests that the risk of postpartum depression in cesarean delivery is significantly higher than that in vaginal delivery. Therefore, postpartum depression in cesarean delivery may require more attention and treatment.Tramadol is a non-opioid central analgesic that relieves common to severe pain, and tramadol has an inhibitory effect on norepinephrine and serotonin systems and has the potential to reduce depression and anxiety. Therefore, for the analgesic demand and antidepressant demand for maternal who undergoing cesarean section, tramadol may be an optimized and effective analgesic for the prevention and treatment of postpartum depression.

NCT ID: NCT03307070 Recruiting - Clinical trials for Major Depressive Disorder

Adapted Cognitive Behavioral Treatment for Depression in Patients With Moderate to Severe Traumatic Brain Injury

Start date: September 23, 2017
Phase: N/A
Study type: Interventional

The first aim of this study is to develop a structured, cognitive behavioral treatment manual for major depressive disorder (MDD) adapted for individuals with moderate to severe traumatic brain injury (TBI) (CBTx-TBI), as well as evaluate its acceptability and tolerability in an open 12-week pilot trial (N=10). The second aim is to evaluate the acceptability and tolerability of, and adherence to, CBTx-TBI in a randomized waitlist-controlled, 12-week pilot trial (N=40). A third, exploratory aim is to evaluate the potential efficacy of CBTx-TBI for MDD in the randomized pilot trial (N=40) and possible moderators and mediators of outcome.

NCT ID: NCT03304301 Recruiting - Quality of Life Clinical Trials

Effect of Sunlight Exposure and Outdoor Activities on Depression, Cognition and Quality of Life in the Elderly

Start date: June 30, 2016
Phase: N/A
Study type: Interventional

Background: The transition to long-term care facility can be a stressful and emotional event for the elderly. The evidences showed that the prevalence of depression and the cognition impairment were higher in the institutionalized elderly than the community dwelling elderly. It could affect the quality of life of the elderly and increase risk of mortality. Purpose: The aim of the study is to evaluate the effect of outdoor activities and sunlight exposure on depression, cognitive function, and quality of life among institutionalized elderly. Method: The design is a randomized control trial. Participants will be randomly allocated to experimental or control groups by block randomization. In the experimental group, participants will be encouraged to reduce time spent on bed and bedroom. Nurses, nurse aids or family will take participants outdoors and exposure their face, hands or arm to sunlight for 15-30 minutes a day, five days a week for three months (if the UV index is over 8 according to the forecast of Center Weather Bureau, the participants will be asked to stay inside). In the control group, the participants will receive routine care. The control group will neither be encouraged to stay outdoors nor limit the chance to exposure to sunlight. Expected outcome: The expected benefit of the research is to improve the depression, cognitive function, and quality of life of the institutionalized elderly.
