Filter by:The goal of this study is to test whether a single low-dose of IV ketamine given in the emergency department to adolescents with treatment-resistant depression and suicidal ideation can reduce depression symptoms and suicidal thoughts compared to placebo. Participants will complete depression scales at baseline, and 1 hour, 3 hours, 1 day, 3 days, and 7 days after receiving the treatment.
Severe uterine contractions in labor can trigger emotional disorders including postpartum depression in women during the puerperium. Numerous studies have shown that resting frontal electroencephalogram (EEG) asymmetry is closely related to depression. Therefore, the investigators hypothesize that the frontal alpha asymmetry in EEG during uterine contractions in the first stage of labor be associated with the risk level of postpartum depression. The objective of this research is to investigate, in a 1-year period, the incidence of postpartum depression in natural birth mothers in relation to frontal alpha asymmetry in EEG during uterine contractions and resting state.
Large register based work has shown that starting on oral contraceptives (OCs) is associated with an increased risk of developing depressive episodes. It is not known why this is, but changes in the serotonergic brain system might play a role. Intriguingly, in cross-sectional work, the investigators have demonstrated a lower level of the serotonin 4 receptor globally in the brain of healthy women using oral contraceptives compared to non-users. The order of magnitude of this difference is comparable to what has been observed in depressed individuals relative to healthy controls. In this study, the investigators will apply a longitudinal design to determine if starting on oral contraceptives induces a reduction in the serotonin 4 receptor in healthy women and whether such changes are related to potential changes in measures of cognition as well as mood/affect and sexual desire. The study is a single-blind randomized placebo-controlled trial with a 3-month intervention paradigm of either Femicept (2nd generation combined oral contraceptive) or placebo. The investigators will include participants until 20 women have completed the study in each arm. Participants will go through an investigational program, including PET and MR brain scans and neuropsychological testing, before starting on the treatment and again during the third pill cycle. To capture changes in mood/ and sexual desire, the participants will complete daily questionnaires during the baseline menstrual cycle and during third pill cycle. A linear latent variable model will be used to evaluate if OC use induces changes in the serotonin 4 receptor level and such changes will be correlated to changes in secondary outcomes (i.e., cognitive and psychometric measures).
The aims of this study are to: 1. Determine the proportion of participants who are underdosed or overdosed under recommended dosing regimen of sertraline for the depression treatment (100 mg/day) 2. Determine and quantify clinical benefits of personalized sertraline dosing regimen based on the sertraline blood level monitoring 3. Retrospectively estimate whether the information on CYP2C19 genotype is useful in prediction of sertraline blood level.
The aims of this study are to: 1. Determine the proportion of participants who are underdosed or overdosed under recommended dosing regimen of escitalopram for the depression treatment (10 mg/day) 2. Determine and quantify clinical benefits of personalized escitalopram dosing regimen based on the escitalopram blood level monitoring 3. Retrospectively estimate whether the information on CYP2C19 genotype is useful in the prediction of escitalopram blood level.
Postpartum depression (PPD) may impair the mother-infant relationship and lead to both short and long-term suboptimal development of the baby. This study aims to evaluate the effectiveness of a targeted intervention (HUGS: Happiness Understanding Giving and Sharing) for enhancing the mother-infant relationship.
The purpose of this study is to evaluate the efficacy and mediators of change in Positive Affect Treatment, a psychotherapy specifically aimed at enhancing reward sensitivity in individuals with low positive affect (a core feature of anhedonia) in the context of depression or anxiety. Target enrollment is 100 male and female participants with low positive affect and depression or anxiety and impaired functioning, between the ages of 18 and 65 years, who will be randomized to either Positive Affect Treatment or Negative Affect Treatment (designed to reduce threat sensitivity). Participants will complete laboratory tests, psychiatric assessments, and self-report questionnaires as part of the study. The total length of participation is around 5 months.
Prevention of depressive disorders has become a key priority for the NIMH, but the investigators have no widely available public health strategy to reduce morbidity and mortality. To address this need, the investigators developed and evaluated the primary care based-technology "behavioral vaccine," Competent Adulthood Transition with Cognitive-Behavioral Humanistic and Interpersonal Therapy (CATCH-IT). The investigators will engage N=4 health systems representative of the United States health care system, and conduct a factorial design study to optimize the intervention in preparation for an implementation study and eventual dissemination.
Depression is a leading cause of morbidity and mortality, conferring substantial healthcare and societal costs. By studying methods to non-invasively target neural circuitry involved in reward responsivity, information generated by this project will improve understanding of the circuit alterations that underlie motivation and pleasure deficits in depression, and could also lead to the development of biologically-based markers of neurostimulation-based treatment response.
Post-stroke depression (PSD) is a common complication of stroke that leads to dysfunction and reduces the quality of life. PSD exacerbates cognitive dysfunction, delays the recovery process, and increases the disability, mortality and recurrence rates of stroke. Therefore, early clinical treatments for PSD are important to improve the prognosis and restore the social functions of stroke patients. Integrated rehabilitation has significant advantages in the treatment of PSD. First of all, there is a wide range of rehabilitation methods, such as acupuncture, traditional Chinese medicine, and repetitive transcranial magnetic stimulation, which have been proved to be effective for PSD. However, as the application of integrated rehabilitation becomes more and more widespread, its shortcomings are gradually emerging. For example, most of the treatment protocols used in clinical studies are based on personal experience of the investigators, a unified protocol has not yet been formed; treatment methods are still insufficient in standardization and reproducibility. More studies focus solely on the improvement of a certain symptom by a certain rehabilitation therapy, but ignore the important theoretical basis of the "holistic concept", thus showing the uneven clinical efficacy. For the above existing problems, it is necessary to conduct original and innovative research.
