24 Clinical Trials for Various Conditions
This is a randomized, double-blind, placebo-controlled, 4-week intervention clinical study assessing the efficacy of Mirtoselect®, Virtiva® Plus, and Enovita® on cognitive performance and mood states, and the occurrence of adverse events in response to daily supplementation. The desired sample size for this study is 64 subjects. To account for potential dropouts, we aim to enroll up to 20% over the desired sample size. Therefore, this study will enroll up to 76 healthy men and women (25-55 years of age). Subjects will be randomly divided into four study groups: Placebo, Virtiva® ginkgo biloba extract, Mirtoselect® bilberry extract, or Enovita® grape seed extract. Blocked randomization will be deployed in which subjects are divided into blocks of 4 subjects and each subject within a block is randomly assigned to one of the four study groups.
Optimizing treatments in mental health requires an easy to obtain, continuous, and objective measure of internal mood. Unfortunately, current standard-of-care clinical scales are sparsely sampled, subject to recency bias, underutilized, and are not validated for acute mood monitoring. The recent shift to remote care also requires novel methods to measure internal mood. Recent advances in computer vision have allowed the accurate quantification of observable speech patterns and facial representations. The continuous and objective nature of these audio-facial behavioral outputs also enable the study of their neural correlates. Here, the investigators hypothesize that video-derived audio-facial behaviors have discrete neural representations in the limbic network and can provide a critical set of reliable longitudinal estimates of mood at low cost across home and clinic settings.
Background: Mood disorders, such as bipolar disorder, can have serious effects on a person s life. People with bipolar disorder are more likely to have heart disease and abuse substances. In this natural history study, researchers would like to learn more about the connection between exercise and mental health in people with and without mood disorders. Objective: To better understand relationships among physical activity, sleep, and mental health. Eligibility: People aged 12 to 60 years with a history of a mood disorder. Healthy spouses and relatives with no mood disorders are also needed. Design: Participants will be in the study up to 2 years. For up to 20 days in a row, at 4 times during the study, participants will: Complete an electronic diary on their smartphone. Participants will answer questions about their mood, health, sleep, and daily activities. Wear an activity monitor, like a wristwatch, that records how much they move. Wear a light sensor, as a necklace, to record the amount of light in their environment. Some participants will do additional tests. Twice during the study, for 3 days in a row, they will: Wear monitors to record their temperature, heart rate, and sleep. Provide saliva samples. Complete cognitive tasks on their smartphone. Participants will visit the NIH clinic 2 times. They will have a physical exam, with blood and urine tests. They will wear a heart monitor. They will ride a stationary bike for 30 minutes. They may have an imaging scan. Some participants will stay overnight. They will go to sleep wearing a cap to measure their brain activity.
Many athletes anecdotally report modifying their nutritional intake before competition in order to avoid gut problems, but no studies have evaluated whether emotional state impacts tolerance to pre-exercise feeding. Therefore, this study will use movie clips (stressful, horror, and funny/amusing) to induce different mood states and emotions, which will be followed by ingestion of food before endurance running on a treadmill. In addition, metabolic and physiologic responses to mood induction will be evaluated.
The objective of this research is to record mood states and depression levels in healthy college students before and after 4 weeks of daily vinegar ingestion.
Purpose of Study The purpose of this crossover study was to determine how vitamin B6 supplementation impacts mood states in college age (18-25 y) women that use oral contraceptives, in comparison to a placebo treatment. Hypothesis Daily supplementation of vitamin B6 (100 mg) over a 4-week period will improve mood states in college age women (18-25 y) with marginal vitamin B6 status that use oral contraceptives, compared to the placebo treatment.
Stretching and flexibility exercise such as yoga and functional resistance exercise are two forms of exercise that are growing in popularity. However, they have not been scientifically tested to demonstrate their ability to improve body composition, fitness, heart and metabolic health, and mood state in overweight/obese women. The investigators hypothesize that during an 11 week intervention, both forms of exercise will improve body composition, heart and metabolic health and mood state.
The proposed clinical studies will evaluate the acute effects of nicotine on the hypothalamic-pituitary-gonadal axis in women to test the hypothesis that nicotine alters gonadal steroid hormones, and/or disrupts feedback regulation of ovarian hormones by anterior pituitary hormones.
The proposed clinical studies will analyze the interactions between nicotine, alterations in endocrine hormones, mood and cardiovascular measures. They also intend to examine the contribution of gender and menstrual cycle phase. These studies hypothesize that this novel focus on nicotine's rapid hormonal, cardiovascular and subjective effects will be important for developing novel biologic approaches to treatment for nicotine abuse and dependence as well as advancing our understanding of the neurobiology of nicotine reinforcement.

The purpose of this study is to determine the effect of lacosamide on mood and quality of life in people with epilepsy.
The investigators hope to see if a commonly used drug such as ketamine could help depressed ER patients feel better and improve their mood quickly.
The goal of this clinical trial is to examine the impact of a specific guided meditation (Twin Hearts Meditation; THM) on cognitive functioning and EEG dynamics in experienced and inexperienced meditators. The main questions it aims to answer are: * Will the experienced meditators outperform inexperienced meditators on the attention control tasks (Flanker, Trails A \& B) at baseline (pre-meditation)? * Will both groups show improvements in performance after meditation associated with mood and physiological state changes? * Will the experienced meditators show an overall mood profile of higher positive mood states and less negative mood states (Brunel Mood Scale subscale difference) at baseline (pre-meditation)? * Will both groups show mood state improvements after meditation? * Will the experienced meditators show differences in electrophysiological characteristics compared to inexperienced meditators? * Will inexperienced meditators exhibit shifts from their baseline resting-state EEG towards being more similar to the EEG characteristics of experienced meditators at baseline? * Will experienced meditators demonstrate differences in P300 latencies and amplitudes on the auditory oddball paradigm. Participants will: * Take a series of pre-meditation surveys. * Complete pre-meditation P300 auditory oddball task. * Complete pre-meditation cognitive behavioral task set. * Continuous 19-channel EEG recording before and after pre-recorded guided THM. * Take a series of post-meditation surveys. * Complete post-session P300 auditory oddball task. * Complete post-session cognitive behavioral task set.
Aerobic exercise impacts bodily processes implicated in the pathophysiology of major depression. Consistent with these effects, aerobic exercise in general, and running in particular, has been repeatedly shown to have both immediate mood elevating and longer-term antidepressant effects. To the investigators' knowledge, all studies of running as a therapeutic intervention for mood have had subjects run in standard running shoes, despite increasing evidence that running barefoot or in shoes with minimal effect on foot strike (i.e. "minimally shod") leads to marked changes in how people run in ways that might have physiological effects of relevance to health. Thus, nothing is currently known about differences in effects on depression-relevant physiological or emotional functioning between running either barefoot or minimally-shod vs. running in standard running shoes (hereafter called "shoed). The current pilot study is designed to begin addressing these issues by examining effects of minimally shod vs. shoed running on non-invasive measures of autonomic nervous system (ANS) functioning and mood state.
The purpose of this research is to examine the effectiveness of a 4-week immersive-virtual reality (VR) exercise bike intervention on college students' physiological outcomes (physical activity levels, cardiovascular fitness, and body composition) and psychological outcomes (situational motivation, situational interest, mood states, and depressive symptoms).
This study aims to examine the effects of Sourse's Hype Bites at being able to increase vitamin B12 levels to promote positive health outcomes. Participants will consume Hype Bites daily. Participants will also take surveys and blood samples to examine both the subjective experience of taking Hype Bites as well as changes in biomarkers across the trial.
The objective of the research is to test the hypothesis that participating in group-based gardening or group-based art activities may alter the mental health and cardiac physiological status of a wellness population of women ages 26-49. Assessment of the effects of gardening or art activities on the experimental population will take two approaches, the first being the use of physiological measurements of heart rate and blood pressure. The second approach will employ six widely used and well-established self-reported assessment instruments that will capture information about the health and well-being of participants. These measurements and assessments will provide a psychometrically-based before and after mental health status and between treatments health summaries of the participants in the gardening group and those engaged in the art group activities.
Hypobaric hypoxia (decreased oxygen supply to body tissues due to low atmospheric pressure) caused by exposure to high altitude disrupts sleep. Sleep deprivation is associated with degraded post-sleep performance of neurobehavioral tasks. The lowest altitude at which sleep and/or post-sleep performance are affected is not known. The study hypothesis is that sleep and/or post-sleep performance of neurobehavioral tasks will occur due to hypobaric hypoxia at altitudes of 8,000 or less.
AD 452 is a new drug which is being developed for use in adult patients with RA. It is believed that AD 452 may modify the underlying disease of RA as well as improving RA symptoms, and in order to establish its efficacy and safety, AD 452 is being tested in a 3 month study. Patients enrolled in this study will already be taking methotrexate for their RA and they will remain on methotrexate throughout the study. An earlier clinical study in 98 subjects with RA on stable background therapy investigated the pharmacokinetics, safety and tolerability of AD 452 taken for one month. The drug was well tolerated and no significant drug related adverse events were reported.
Given the public health and social relevance of sexual aggression and the gap in the extant literature regarding state anger, emotion regulation, alcohol, and sexual aggression, the present study will contribute to our understanding of emotion regulation's role in sexual aggression perpetration. The proposed 2-year research plan will examine the effects of alcohol intoxication, state anger, and emotion regulation on men's sexual aggression intentions. This study will recruit non-monogamous, men (individuals who identify their gender as male and whose biological sex is male) who have sex with women, ages 21-35. While more research on female perpetrators is needed, the proposed study will exclusively recruit males for the following reasons: 1) the scientific literature indicating the majority of sexually aggressive acts are perpetrated by men; and 2) the current sexual aggression analog has not been piloted with female participants and would require preliminary experiments to determine its appropriateness. The study will utilize a 2x2 design in which participants are randomized to beverage condition \[alcohol (target BAC= .08gm%) or control (no alcohol control)\] and an emotion induction (anger induction or control). The outcomes will be assessed using a sexual aggression analog which participants will complete on the descending limb of alcohol intoxication and indicate the likelihood that they would engage in various sexually aggressive acts. The study also includes self-report measurements of state anger and emotion regulation to explore emotion regulation as a moderator in the associations among alcohol intoxication, state anger, and sexual aggression intentions.
The purpose of this study is to examine state representation in individuals aged 18-30 who have been diagnosed with a psychotic illness, as well as young adults who do not have a psychiatric diagnosis. State Representation is our ability to process information about our surroundings. The investigators will complete some observational tests as well as a cognitive training clinical trial.
This study will evaluate the effectiveness of an integrative group psychosocial therapy combined with stimulant medication in treating children with attention deficit hyperactivity disorder plus impairments in mood.
Background: Irritability is an elevated proneness to anger. Children with irritability have difficulty tolerating frustration. They get angry and have temper outbursts more easily than their others their age. Irritability is a symptom of DMDD and ADHD. (DMDD is disruptive mood dysregulation disorder. ADHD is attention deficit/hyperactivity disorder.) Yet the reasons why some children get irritated easily are not well understood. Objective: To use brain imaging methods to study responses to frustration in youth. Eligibility: Youth aged 8 to 17 years with severe irritability (including those diagnosed with DMDD) and/or ADHD. Healthy volunteers are also needed. All participants are already enrolled in studies 02-M-0021 or 01-M-0192. Design: Participants will visit the clinic 3 times. The second and third visits will be 3 to 4 weeks apart. The first visit will be an enrollment visit. They will receive training on the tasks they will do during the study. Participants and their parents will take surveys. They will answer questions about their moods and feelings. Participants will train for an MRI scan. They will lie in a mock scanner tube and hear the noises an MRI makes. On the second and third visits, participants will have real MRI scans. They will play a computer game or watch a movie during each scan. The scans will last about 1 hour. The week after each scan, participants will wear a device on their wrist to measure their heart rate and activity level. Participants and their parent will use a smartphone to answer questions about how they are feeling and acting. Participants who do not have smartphones will be given one to use during the study.
The purpose of this study is to evaluate the effectiveness and safety of flexible-doses paliperidone ER (3 to 12 mg as needed) compared with placebo over 3 weeks in patients with Bipolar I Disorder who are experiencing an acute manic or mixed episode. This study will also evaluate the effects of paliperidone ER on global functioning, and will compare the effectiveness of flexible doses of paliperidone ER to that of quetiapine over 12 weeks.
