Mood

The postpartum period, also defined as the fourth trimester of pregnancy, encompasses the approximately 6-8 week period following childbirth, during which the organs that underwent changes during pregnancy return to their previous state. This period is of great importance in terms of protecting the health of both mother and baby, meeting their care needs, and increasing their comfort. During the postpartum period, women experience physiological, psychological, and social changes; hormonal changes, assuming parental roles, changes in family dynamics, and increased responsibilities related to infant care can lead to adjustment difficulties. This can cause problems for the mother in both her own care and infant care. In the postpartum period, mothers may experience various health problems such as pain, fatigue, sleep disturbances, infections, breastfeeding problems, hemorrhoids, constipation, urinary incontinence, depressive symptoms, and mood swings. Pain, in particular, arises due to uterine contractions, breast engorgement, nipple tenderness, and other complications, negatively affecting the mother's mobility, sleep patterns, social interaction, and quality of life. Furthermore, stress and adjustment problems experienced during the postpartum period can lead to serious psychological problems such as delayed maternal bonding, postpartum blues, postpartum depression, psychosis, and communication problems between couples. Pharmacological and non-pharmacological methods are used in the management of these problems. However, due to the negative effects that pharmacological methods may have during breastfeeding, interest in complementary and alternative medicine practices has increased. Reflexology, aromatherapy, music therapy, acupressure, and Reiki are among these methods. Reiki is an energy therapy method that aims to balance an individual's life energy and support the natural healing process, applied through touch or the placement of hands on specific points. Reiki application is reported to have positive effects on pain, stress, anxiety, sleep quality, and coping skills. Although it is one of the preferred methods for adapting to changes and reducing problems experienced in the postpartum period, studies directly examining the effects of Reiki application on postpartum recovery quality, comfort, and mood are quite limited. Due to its low cost, ease of application, and lack of side effects, Reiki is considered an important complementary care approach that can be used in the postpartum period. The aim of this study is to determine the effect of face-to-face Reiki treatment on the quality of postpartum healing, comfort level, and mood in women who have had cesarean deliveries, on days 1, 2, and 7 of the postpartum period.

Twenty healthy adults (≥21 years old) will be enrolled to evaluate the efficacy of a single oral dose of psilocybin (25 mg) administered with or without pretreatment using oral pimavanserin (34 mg) or placebo. Outcome assessments will occur at 1 week and 1 month following psilocybin administration. The purpose of this study is to clarify the receptor-level mechanisms underlying psilocybin's effects on mood and well-being, along with the associated neurophysiologic signatures. These mechanisms will be examined using psychometric scales, autonomic and fMRI-based neurophysiologic markers, and integrated pharmacokinetic/pharmacodynamic modeling.

The purpose of this study is to investigate the effects of Binaural Beat Music (BBM; personalized music playlist with binaural beats), Spatialized Music (SM; personalized and spatialized music playlist), their combination, and possible interaction on older adults in an assisted living community who are either living with a dementia diagnosis or are experiencing typical age-related changes. The control condition is a personalized music playlist without binaural beats and spatialization. It is hypothesized that BBM, SM, and their combination each improve aspects of BPSD compared to controls over a two-week intervention period. The Specific Aims of the study are (1) to evaluate whether BBM, SM, and/or their combination is superior to control in reducing BPSD severity (primary outcome); (2) to evaluate whether BBM, SM, and/or their combination is superior to control in reducing caregiver distress (secondary outcomes); and (3) to evaluate the effects of BBM, SM, and/or their combination on improving overall well-being and mood (secondary outcomes).

This is a clinical trial aimed to investigate if a novel phytochemical and fibre-rich snack can improve perimenopausal symptoms and well-being in perimenopausal women aged 40-55 and not on hormone replacement therapy. Hypothesis: The investigators hypothesise that the phytochemical and fibre-rich snack will improve perimenopausal symptoms via a gut microbiota mediated mechanism. Main research questions: Does eating the snack every day lower menopause symptoms such as hot flushes, night sweats, mood changes, and sleep problems? Does the snack improve mood, stress, anxiety, sleep, and overall quality of life? Does the snack improve the balance of bacteria in the gut, and could this be part of how it helps symptoms?

Hypothesis: Consumption of a collagen supplement for 8 days will improve quality of life and improve glycaemic control in comparison with a placebo in individuals overweight or with obesity with a perceived low quality of life. Participants will be asked to: 1. Consume a collagen peptide supplement for a total of 8 days at a time 2. Fill in questionnaires about quality of life, appetite, mood and energy 3. Wear continuous glucose monitors

This study investigates the cognitive effects of Ārepa, a blackcurrant-based drink, under simulated high-altitude conditions (4,500m normobaric hypoxia for \~180 minutes). Using a double-blind, randomised, placebo-controlled crossover design, participants will consume either the nootropic blackcurrant-based drink or a taste-matched placebo. Cognitive testing (\~80 minutes) includes Trail-making, Stroop, N-back, Serial 7s/3s, and RVIP tasks. Physiological measures (heart rate, SpO₂, blood) and biomarkers (MAO-B, BDNF, hsCRP, S100B, Prolactin, C3G, Sarmentosin) will be assessed. Scales will evaluate mood, wellbeing, and perceived effects. The aim is to determine if the nootropic drink can support cognitive function in hypoxic environments.

This study explores the effects of 7-day losartan (50mg) versus placebo with brief behavioural activation on emotional processing in young volunteers low in positive mood

The Developing Resilience and Anxiety Management Through the Arts (DRAMA) Study examines the degree to which the arts can help to address stress, anxiety, and sad mood in children and adolescents. The researchers will pair theatrical improvisation exercises with cognitive-behavioral therapy (CBT) techniques versus improvisation exercises alone versus a social craft group on reducing elevated levels of anxiety and depression.

The goal of this clinical trial is to learn if a Nepalese Pepper Extract (Zanthoxlum Armatum, ZA) supplement can improve cognitive performance and mental abilities in competitive gamers aged 16 to 34. The main questions it aims to answer are: 1. Does ZA supplement improve cognitive abilities like attention, memory, and decision-making? 2. What is the most effective dose of ZA supplement (300mg vs 150mg)? 3. How do the effects of ZA supplement compare to caffeine? Researchers will compare four different treatments (high-dose ZA, low-dose ZA, caffeine, and placebo) to see if ZA supplement produces better cognitive performance than placebo and how it compares to caffeine\*\*. Participants will: * Complete a screening visit with health checks and training on computer tasks * Attend four testing visits (7-14 days apart) where they receive different treatments * Avoid alcohol and energy drinks for 24 hours before each visit, and caffeine from waking * Take assigned treatment at 11:30am and complete cognitive tests at -1, 1, 3, and 5 hours in relation to dose. * Complete mood questionnaires, sleep assessments, and gaming-specific tasks (aim training, character control) * Wear heart rate monitors during testing * Eat standardized meals provided during visits * Play competitive games at home in the evening and complete performance questionnaires

Previous studies have shown that polyphenol-rich foods can positively affect cognitive functions, memory, and mood in humans. We hypothesize that both acute and chronic intake of muscadine wine polyphenols will improve cognitive performance and mood through regulating the HPA axis, alleviating inflammation and oxidative stress, and/or inhibiting monoamine oxidase activities

The aim of the study is to investigate the acute and chronic effects of a supplement containing Caffeine, Vitamins, Minerals and Botanical extracts on cognitive function, sleep and wellbeing, in healthy volunteers. The study will follow a randomised, double-blind, placebo-controlled, crossover design. Participants will receive both treatments, and both study arms will include an acute testing visit (day 1) and a chronic testing visit (day 29). The active treatment contains a blend of 120mg caffeine, vitamins, minerals and botanical extracts and the matched placebo treatment contains marigold extract and brown rice flour. The trial will use computerised cognitive tasks, administered via COMPASS software (Northumbria University, UK), online cognitive assessments via Cognimapp and self-reported questionnaires and sleep diary, as measures of the outcome variables. 90 participants will participate, aged 18-75, and self-ported as being in good health. Participants will be randomly allocated to a treatment order and will be supplied with either the active treatment or the placebo whilst visiting the research centre for the acute testing visits. Participants will take the treatment home to consume daily for the duration of the supplementation period. Participants will record the time of taking treatment each day in a treatment diary which will be returned to the research centre, along with any unused treatment, at each chronic testing visit.

Compared to the control condition, evening-exercisers prescribed morning exercise will exhibit improved sleep quality (increased efficiency, decreased fragmentation) and increased sleep duration. Aim 2. Compared to the control condition, evening-exercisers prescribed morning exercise will exhibit improved mood (increased positive affect, decreased depression, anxiety and anger). Aim 3. Compared to the control condition, evening-exercisers prescribed morning exercise will exhibit decreased stress and increased productivity.

Purpose of this study: The purpose of this study is to learn more about how hormonal oral contraceptives affect brain processes and emotional wellbeing. Procedures: If participants agree to participate, the following will happen: 1. Eligibility visit (remote screening session) 2. If participants are eligible to participate in the study, they will be placed in one of two groups. If they are in the first group, they will be asked to take an oral contraception pill ("study drug") every day for 21 days. If they are in the second, they will take a placebo every day for 21 days. A placebo is a pill that looks like medicine but is not real and will have no medical effect on participants. Participants will not get to choose which group they are in, nor will they be told which group they are in. 3. During the three-week period in which participants will take either the study drug or placebo, they will be asked to complete daily check-in surveys on their computer or mobile device. 4. Participants will be asked to attend two additional visits over the course of about three weeks. At these visits, participants will be asked to undergo a urine drug screen, a blood draw, and a magnetic resonance imaging (MRI). They will also be asked to complete behavioral questionnaires.

This is a digital health study in which participants are recruited to collect sleep and activity data from digital activity trackers. We are also collecting survey/questionnaire data on baseline health and sleep characteristics as well as bi-weekly assessments of sleep quality and mood. Overall, we aim to examine how sleep relates to physical and mental health in a large population of activity tracker users.

The goal of this clinical trial is to test the effectiveness of an intervention designed to improve wellness through aromatherapy. The main question it aims to answer is whether this intervention can deliver beneficial psychological effects on stress, anxiety and mood, as well as overall well-being. Participants will receive a bottle with a no/neutral odor or an essential oil (or a blend of essential oils) for home administration and will be asked to complete a series of scales pre and post self-administration twice one week apart.

The investigators will examine the acute effects of stimulant medication on executive functioning. The rationale for the proposed study is to examine the efficacy of stimulants for college students with ADHD and help prevent stimulant misuse among college students without ADHD. The working hypothesis is that stimulants, compared to baseline and placebo conditions, will improve executive functioning for college students with ADHD but not for college students without ADHD. Improvements on executive functioning measures (e.g., CPT-IP, Spatial Span) will be examined through 2 (ADHD vs. non-ADHD) x 3 (Baseline, Placebo, Stimulant) repeated measures ANOVAs. Follow-up analyses will include paired comparisons. Expected outcomes are to confirm these hypotheses and demonstrate the need for further study of stimulants. If confirmed, the results will provide pilot data for a larger NIH grant proposal aimed at further examining the acute effects of stimulants (i.e., improved cognitive functioning with stimulants) and comparing them to the acute effects of physical exercise (i.e., improved cognitive functioning immediately after exercise). The investigators expect this outcome to have an important positive impact because it can help support stimulant medication as an effective treatment for college students with ADHD (DuPaul et al., 2012). Additionally, demonstration that stimulants do not improve executive functioning for college students without ADHD can be used to help prevent and discourage stimulant misuse and diversion on college campuses (Hartung et al., 2013).
