NCT04856410
This study investigates the effects of extended-duration spaceflight (12-month International Space Station missions) on general cognitive performance (measured with the Cognition test battery), spatial cognition, structural and functional brain changes in general, and hippocampal plasticity more specifically relative to the shorter 6-month and 2-month missions.
NCT06489873
The goal of this clinical trial is to learn the impact of lutein, zeaxanthin, and fish oil (LZF) supplementation in healthy adults. The main question it aims to answer is: Will supplementation with LZF improve macular pigment optical density (MPOD), cognitive performance and bone mass compared to controls after six months? Subjects with an MPOD \<.43 will significantly improve MPOD after 6-months of LZF supplementation. Consuming a LZFO supplement for 6-months will improve visual cognitive performance. Consuming a LZFO supplement for 6-months will improve bone density. Participants will be asked to take either a LZF supplement or placebo daily for 6 months.
NCT03771716
REACT is a randomized intervention to examine the benefits of African Dance as a method to increase physical activity behaviors in older adults. In this 6- month intervention, older African Americans will be randomly assigned to either an African Dance or an Africana Culture class. Both before and at the completion of the intervention, the investigators will collect a comprehensive neuropsychological battery and MRI scans of brain health and function to better study how physical activity influences neurocognitive health in African Americans.
NCT07103837
Aging is associated with cognitive and physical decline, leading to an increased risk of falls in older adults. Recent evidence highlights the critical role of cognitive functions-such as attention, memory, and executive functioning-in postural control and fall risk. This study aims to develop and validate a novel Reactive Skill Test (RST) that simultaneously assesses cognitive (reaction time, visual attention, short-term memory) and motor responses in older adults. The test involves matching colored stimuli to targets using a color-coded pod and cone setup controlled via the ReactionX system. The validity of RST will be examined through correlations with established cognitive and fall risk measures, while test-retest reliability will be assessed across separate sessions. This tool may provide early detection of cognitive-motor impairments contributing to fall risk in aging populations.

NCT06693505
This study aimed to examine the impact of caffeinated chewing gum on the cognitive performance of night-shift emergency physicians in a partially sleep-deprived state. A randomized, double-blind crossover controlled experimental design was employed in which fourteen (Age: 29.9 ± 1.44; height: 176.5±5.3; weight: 78.1±13.4) emergency physicians consumed either caffeinated chewing gum (CAF) containing 200 mg caffeine or a caffeine-free placebo gum (PLA) for 10 minutes at 03:30 am during their first 8-hour night shift after at least one day off, and completed cognitive performance tests before shift, mid-shift (10 minutes after gum chewing), and after shift, including included Corsi block test, Task-switching paradigm, Stroop Test, Visual search, and Wisconsin Card Sorting Task. Sleep quality was assessed subjectively by a single question score, and objectively by ActiGraph for one night on the off day and the last sleep before the first night shift, to evaluate the effect of sleep quality on cognitive performance.
NCT06684808
The purpose of the study was to evaluate the effects of 12 weeks of Active Breaks on motor, academic and cognitive performance in elementary school children.
NCT05073406
The aim of the current study is to evaluate under blinded conditions, both in a simulated environment and during helicopter flight, the effect of a rapid (within 20 minutes) exposure to altitude (4000 m asl) on physiological parameters and selected cognitive domains, in providers operating in helicopter emergency medical service (HEMS) exposed to hypobaric hypoxia or to hypobaric normoxia (H0: cognitive effects under hypobaric hypoxia = cognitive effects under hypobaric normoxia). Simulated environment will allow to control different factors. The parallelism between a study branch conducted in a simulated environment and another one conducted under a real-life condition will allow to evaluate the additive effects on additional stressor factors (processive and systemic ones). * Simulation branch: each participant will take part in three research sessions: a familiarization session and two experimental sessions in simulation facility called terraXcube (test 1 and 2). On test 1 and test 2 each group will be exposed twice to the simulated altitude of 4000 m asl (under hypobaric hypoxia or hypobaric normoxia conditions) according to the randomization protocol. Participants will perform the neurocognitive tests three times on each of the two tests: before the ascent (TC0), after 5 min from the end of the ascent (TC1) and after around 30 min (TC2), to investigate European Union Aviation Safe Agency (EASA) proposed recommendations. After completing each neurocognitive test session, participants will be asked to rate their performance using a visual analogue scales (VAS). All participants will wear the vital parameters monitoring system during the entire duration of the tests inside the chamber, as well as the cerebral oxygen saturation (ScO2) sensor. Samples will be collected by saliva, urine and/or capillary blood. The same schedule is repeated in each test session. * In-field branch: each participant will take part in three research sessions: a familiarization session and two experimental sessions during helicopter flights (test 1 and 2). On test 1 and test 2 each group will be exposed twice to the altitude of 4000 m (under hypobaric hypoxia or hypobaric normoxia conditions) according to the randomization protocol. Participants will perform the neurocognitive test two times on each test: before the ascent (TC0), after around 5 min from the end of the ascent (TC1). After completing each neurocognitive tests, participants will be asked to rate their performance using a visual analogue scales (VAS). All participants will wear the vital parameters monitoring system during the entire duration of the tests. Samples will be collected. The same schedule is planned in each test session.

This trial investigated the impact of providing a regular meal with and without additional multiple micronutrients for children in Northwest Pakistan on their performance at school, in comparison to a local government school that served as a control i.e. no school meal.
NCT05226039
The current clinical study will have two groups of participants (young adults ages 20 - 30, and older adults ages 60 - 70) take part in three visits to the lab. On the first visit participants will fill out questionnaires assessing demographics and physical activity level. On the 2nd and 3rd visits participants will be engage in both a moderate intensity bout of aerobic exercise for 20 minutes, and 20 minutes of resting on a stationary bike watching an educational video. These two visits will be counterbalanced across age groups. Following both the exercise bout and the resting control condition participants will complete cognitive tasks assessing episodic memory and executive functioning. The first hypothesis is that older adults who are more physically active (assessed via questionnaire) will have significantly greater cognitive abilities compared to those who are less active or sedentary. The second hypothesis is that following a single bout of moderate intensity aerobic exercise, older adults will have a greater magnitude of change in their short-term memory, and long-term memory performance compared to younger adults.
NCT05204823
The objective of the study is to evaluate the glycemic index and glycemic load of 4 chocolate milk drinks.
NCT04974606
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.
NCT03321227
The purpose of the present study is to determine the effects of eggs and egg components on cognitive performance and appetite in children aged 9-14 years, as well as to identify the underlying physiological mechanisms in this relationship.
NCT03627637
Cognitive performance is negatively related to an impaired glucose metabolism, possibly due to impairments in brain vascular function. Supported by the statement from the American Heart and American Stroke Association that healthy plant-based diets, which consist of soy foods, protect against cognitive decline, we now hypothesize that soy-induced changes in glucose metabolism cause beneficial effects on brain vascular function thereby improving cognitive performance. The primary objective of this intervention study is thus to evaluate in elderly men and women the effect of a 16-week soy intervention on cerebral blood flow, as quantified by the non-invasive gold standard magnetic resonance imaging (MRI) perfusion method Arterial Spin Labeling (ASL). Cerebral blood flow is a robust and sensitive physiological marker of brain vascular function. Secondary objectives are to examine effects on glucose metabolism using the oral glucose tolerance test and cognitive performance as assessed with a neurophysiological test battery.
NCT03350100
A number of studies have considered the neuroprotective effects of date fruit on neurodegenerative diseases in animals. However, so far no study has addressed the acute effects of date fruit on mood and cognitive performance in humans. This study will investigate the acute effects of two different cultivars of Saudi dates on mood and cognitive performance into healthy volunteers. This study will follow a double blind, randomised, placebo controlled, repeated measures, cross over design with two active treatment arms versus placebo. Treatment orders will be counterbalanced with the use of a Latin Square design. Thirty six healthy participants aged between 18 and 35 will be recruited. Participants will be required to undergo a screening/training visit, followed by three measurement visits at weekly intervals. The trial will last for 3 months in total.
