Filter by:The primary aim of this randomised, double-blind, placebo-controlled, cross-over study is to assess the short-term cognitive effects of a single dose (300 mg) of Mango Leaf Extract compared to a placebo on cognitive function, including during cognitively demanding task performance. The trial will utilise the COMPASS cognitive assessment system and cognitive demand battery (CDB), and Profile of Mood States (POMS), visual analogue mood scales (VAMS), and Stress Visual Analogue Scales (S-VAS) with assessments taking place at baseline, 30 minutes, 180 minutes and 300 minutes post treatment, on two separate testing days separated by 7 days (minimum).
Oral ATP disodium (adenosine 5'- triphosphate disodium) is a commercially available product available alone and as a constituent in a number of sports supplements that is purported to maintain ATP levels and improve performance during high-intensity exercise. Acute deficits in cognitive performance have also been reported in both young adults and children following high-intensity exercise; however, the effects of supplemental ATP on cognitive performance has not been studied. Goals: 1. To investigate the effect of ATP supplementation versus. placebo on mood, reaction time and cognitive performance before and after an acute bout of fatiguing exercise. 2. To investigate the effect of ATP supplementation versus. placebo on anaerobic performance.
Dehydration is defined as the state of water deficit due to excessive water losses and/or small water intake. Underhydration is the result of inadequate water intake leading to activation of water hormonal homeostasis, characterized by elevated vasopressin, lower urinary output, and concentrated urine without any measurable changes in total body water. It is well established that dehydration (water deficit) decreases exercise performance and worsens mood, mainly in women. However, the impact of increased water intake in underhydrated individuals on their exercise capacity and mood is not known. The aim of the proposed study is to investigate the impact of increased water intake in underhydrated individuals on aerobic exercise performance and mood in both women and men.
This study aims to determine the effect short-term dosing (7 days) of a placebo beverage, cranberry juice, cranberry juice + lemon balm extract, cranberry juice + tart cherry powder, or cranberry juice + L-theanine or L-theanine beverage on cognitive function and mood in healthy adults (18-45 years). The study will include measures of attention, alertness, performance, and mood/stress.
In this project, we will examine effects of MA on reward function using electroencephalograms (EEG), which will complement our ongoing study with MA and fMRI. We will determine how MA alters reward-related neural activity and how this is related to its subjective rewarding effects. The effects of MA on reward function will be examined using both reward-task-related activation and resting state activity. We will examine the effects of MA on ratings of drug liking and euphoria, as well as on EEG measures sensitivity to reward. Healthy young adults will undergo three EEG sessions with placebo and MA (10 and 20 mg), while performing the Monetary Incentive Delay task and the Stop Task, as a measure of inhibition. We will examine correlations between the neural responses and subjective responses to MA. Our central hypotheses are 1) that MA will increase feelings of alertness and well-being, and 2) that MA will increase neural responses to anticipation and receipt of reward, and 3) that the effects of MA on mood will be correlated with its effects on neural responses to reward.
Postnatal depression (PND) is a type of depression that can occur in some parents after the birth of their baby. PND has been estimated to affect 1 in 10 new parents; mothers in particular are at an increased risk of developing PND in the first year after childbirth. Symptoms of PND include a persistent feeling of sadness or low mood, a lack of enjoyment and loss of interest in the wider world, lack of energy and feeling tired all the time, difficulty bonding with your baby, withdrawing from contact with other people and problems concentrating and making decisions. Research has shown that mothers with PND have more cognitive, behavioural and interpersonal issues, and lower mood, energy and concentration than mothers without PND. Current treatments for PND include self-help resources, support from local and national organisations, psychological therapy or antidepressants with varying success rates. Further research is required to investigate accessible, cost-effective preventions or treatments for new mothers who are at risk or have been diagnosed with PND. There is also a pressing need to investigate natural alternatives to medication, especially for breastfeeding mothers who do not want to expose their infants to pharmaceuticals through breast milk. Flavonoids are naturally occurring compounds found in high levels in foods such as berry and citrus fruits, leafy green vegetables, tea, dark chocolate and red wine. Evidence suggests that consumption of high flavonoid foods can improve health and cognitive outcomes. Prior research investigating daily dietary flavonoid intervention in a postnatal population for 2 weeks indicated significantly higher physical quality of life and significantly lower state anxiety in mothers of infants under 1 year old, at the end of the intervention. These benefits were not observed in the control group. This data shows promise for the management of mood in a key period for mothers and their babies, where risk of PND is high. The research aim of the current study will be to further these investigations to see whether implementation of a high flavonoid diet across a 2 week period positively affects maternal mental health, specifically mood, anxiety, depressive symptoms and perceived quality of life. The study will involve recruiting mothers of infants under 6 months old to take part in an online study investigating diet and mental health. Mothers will be assigned to either a high flavonoid diet or a control condition for 2 weeks. They will complete online questionnaires (Positive and Negative Affect Scale (PANAS), Edinburgh Postnatal Depression Scale (EPDS), Postpartum-Specific Anxiety Scale (PSAS), World Health Organization Quality of Life (WHOQOL), State-Trait Anxiety Inventory (STAI) and Food Frequency Questionnaire (FFQ) at the start (day 0) and end (day 14) of the dietary intervention. In this study, a sub-sample of fathers will also be recruited to take part in the same study to assess if dietary or mood outcomes are similar or different in this population. This pilot data will inform future research of dietary interventions in new fathers. The study does not pose ethical issues. Participants will be asked to complete non-invasive questionnaires about their mood and quality of life. For those in the high flavonoid group the change to diet will not be extreme; this group will be encouraged to include 2 items from a list of high flavonoid foods in their daily food consumption. All participants will be provided with helplines and web links upon debrief should they wish to seek further support. The helplines provided will be Samaritans UK and PANDAs Foundation. Web links to NHS, MIND and the Association for Postnatal Illness will also be listed.
The primary aim of this randomised, double-blind, placebo-controlled, cross-over study is to assess the short-term cognitive effects of two beverages containing 100 and 300 mg coffeeberry extract (obtained from the fruit of the coffee plant (Coffea arabica) compared to a placebo beverage. The trial will utilise the COMPASS cognitive assessment system and cognitive demand battery (CDB) and mood visual analogue scales (VAS) with assessments taking place at baseline, 60- and 120-minutes post treatment, on four separate testing days separated by 7 days. A treatment containing 75 mg caffeine will be used as a positive control to document participants' responsiveness to an established psychostimulant.
The primary purpose is to test the short-term effects of the acute consumption of two novel beverages made from coffeeberries, the fruit of the coffee plant (Coffea arabica) benchmarked against caffeine on several aspects of cognitive performance. Preliminary studies suggest that flavanols and chlorogenic acids can enhance cognitive performance. It is unknown if drinks formulated with flavanols and chlorogenic acids (without high sugar or caffeine) improve cognition or mood to a similar extent as caffeine. Coffeeberry beverage comparisons will be made to a flavored positive control beverage containing caffeine and a flavored placebo beverage.
This study aims to investigate the acute and chronic effects of an 8 week probiotic intervention (Ecologic Barrier©) on mood and cognitive outcomes in healthy adults.
INTRODUCTION: Bright light therapy (BLT) has demonstrated positive effects on sleep, mood, and behavioral problems in older adults with dementia. However, there is little research in people with advanced stages of dementia. OBJECTIVES: Main objectives are to study the immediate effects, short and long-term effects of BLT in a sample of institutionalized older adults with moderate to very severe dementia. Later, to compare the potential effectiveness of bright light therapy sessions with other non-pharmacological interventions in people with dementia. METHODS AND ANALYSIS: The study was a 2 x 2 randomized controlled trial using a two-group design (BLT vs. control) and two repeated measures (pre- vs. postintervention). In addition, the BLT group participants were assessed immediately before, after, and during each session. The BLT protocol consisted of 30-minute morning sessions of 10,000 lux, Monday through Friday, for 4 weeks. For the statistical analysis, two-way analysis of variance (ANOVA) are used to determine the existence of differences at two points in time (pre- vs. post-). The Wilcoxon signed-rank test or the Paired t test are used to measure changes from before to after the intervention sessions.
