Filter by: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.
This is a prospective, randomized clinical study to evaluate the feasibility and efficacy of a digital neurotherapy on depression, cognition, and quality of life in two groups of patients with major medical illness: 1) a sample of cancer survivors, and 2) a sample of patients with end stage kidney disease (ESKD) on dialysis.
This study aims to investigate whether consuming a drink containing powdered blueberries (equivalent to 150 g fresh fruit) can improve mood and cognition in healthy young adults. Blood biomarkers of inflammation and neurotransmitter turnover will be analyzed as well as responses to computer-based cognitive tasks designed to measure verbal memory, executive function, and emotional processing.
The effect of probiotics on stress and cognitive function in healthy adults with moderate stress
Physical activity (PA) is insufficient in children with three quarters of them who do not meet the WHO's recommendations. Physical inactivity is growing during adolescence; in part due to the time spend in sedentary behaviors at school. The recent literature is highlighting the importance of physical activity on academic achievement, physical fitness and academic achievement in children. In addition, deleterious effects of sedentary behaviors have been demonstrated. At school, many strategies have been settled to break the prolonged sitting time. The use of workstations is one of them and allows to reduce sedentary time at school and increases physical activity without interrupting class. Active workstations like bike desks have demonstrated their effectiveness on physical activity but their effects have not been evaluated in primary school in France. In addition, few studies have evaluated the effects of bike desk use on the child's cognitive abilities. The main objective of this project is to measure the variations linked to the use of bike desks (desk with pedals) for an average of 1h45mn per week (30min 3 to 4 times per week) for 13 weeks during school time in primary school pupils (aged 8 to 11 years) on the cognitive abilities (mental flexibility, working memory and inhibition) of children. Our hypothesis is that the use of the bike desk for 1h45 per week will induce an increase in the attention and cognitive capacities (mental flexibility, working memory and inhibition) of the children. Other improvements that should be identified are the child's body composition, the classroom climate and the well-being of pupils and teachers. The children's physical capacities could also be increased, beyond what is expected given the normal evolution during the year.
Project which objective is a) to test the effectiveness, in preschool children, of an integrated physical activity intervention in the classroom based on intervallic training (MOVI-HIIT) on improving executive function, body composition, cardiorespiratory fitness and b) to evaluate teachers' perceptions of barriers and facilitating elements for the implementation and monitoring of MOVI-HIIT interventions in the classroom.
RATIONALE: Exercise may improve the mood and cognition in young people. PURPOSE: It has been well-known that physical exercise can generally benefit the mental health. However, most evidences that physical exercise improves psychiatric symptoms come from retrospective or cross-sectional studies. Moreover, the studies on the effect of physical exercise in the young adults' mental health were limited. This randomized-controlled trial aims to determinate the effects of a chronic and aerobic exercise on the mood and cognition of young people.
Age-related chronic diseases including dementia, type II diabetes mellitus (T2DM) and cardiovascular disease (CVD) become more prevalent and of increasing societal concern. Common denominators of these co-morbidities are insulin-resistance and impaired vascular function. Animal and short-term human studies now suggest that NWT-03 - an egg-protein hydrolysate - improves insulin-sensitivity and peripheral vascular function, which are risk markers for the development of T2DM and CVD. Insulin-resistance is also associated with cognitive decline, while impaired brain vascular function is an important event preceding the development of impaired cognitive performance. The investigators have already shown in a shorter-term trial (12 weeks) beneficial effects of a daily dose of 5.0 g of NWT-03 on cognitive performance. However, underlying mechanisms have not yet been addressed, while the long-term effects remain unknown. Thus, the investigators now hypothesize that NWT-03 beneficially affects cognitive performance and brain vascular function following long-term daily intake. The primary objectives of this trial are to evaluate in overweight or obese adults (aged 60-75) with subjective cognitive decline (SCD) the effects of a 36-weeks NWT-03 intervention on (1) cognitive performance using a neurophysiological test battery, and (2) cerebral blood flow, as quantified by the current non-invasive gold standard magnetic resonance imaging (MRI) perfusion method Arterial Spin Labeling (ASL). Secondary study objectives are to examine effects on insulin-sensitivity and peripheral vascular function. This intervention study will have a randomized, controlled, parallel design. The total study duration will be 36 weeks. Forty-four older adults (aged 60-75 years) with a Body Mass Index (BMI) between 25-35 kg/m2 (overweight or obese) and subjective cognitive decline (SCD), as assessed with the cognitive failure questionnaire, will participate. These study individuals are known to be at increased risk of cognitive impairment, allowing for improvement by the intervention. During the study, subjects will receive daily (in the morning) 5.0 g NWT-03 or placebo powders for 36 weeks.
A double-blind randomized controlled trial design is used in this study. A mixed design of 2 (pollution reduction group vs. no pollution reduction group) × 3 (high intensity intermittent exercise [HIIT], moderate intensity of aerobic exercise [MICT] and control group [CONT]) is used. 93 subjects recruited by advertising will be randomly divided into 6 groups: high intensity exercise group (pollution reduction vs no pollution reduction), moderate intensity aerobic exercise group (pollution reduction vs no pollution reduction) and Stretching group (Control) (pollution reduction vs no pollution reduction).
This study applies a hypothesis-driven approach to examine the effects of chronic marijuana use on HIV-associated inflammation and its subsequent impacts on central nervous system function, with the goal of identifying the mechanisms through which cannabinoids modulate neurological disorders and other comorbidities in persons with HIV.
