Filter by:Tomatoes and tomato-based products could play an important role in modulating microbiota-gut-brain axis (MGBA) interactions due to their high content of fiber and phytochemicals. Phytochemical metabolites derived from the consumption of tomato-based products can act directly as neurotransmitters in the central nervous system, crossing the blood-brain barrier, or indirectly by modulating the MGBA. These metabolites can thus alter gut bacterial composition and brain biochemistry. Therefore, researchers propose a new interventional study to assess the impact of daily tomato consumption in the organism, and to evaluate the effect on the MGBA. The final aim of this study is to spread a message of the health benefits of tomato consumption for the general population.
The goal of this observational study is to study the effect of gene polymorphism on cognitive improvement in response to exercise in healthy participants. The main questions it aims to answer are: To investigate whether FNDC5/Irisin genotype polymorphism affects cognitive function and inter-individual variability in exercise response. To explore whether the FNDC5/Irisin gene polymorphism can act alone or interact with the BDNF gene to cause inter-individual differences in cognitive function responses to exercise gain. Participants will be asked to perform high-intensity interval training( HIIT) on a cycle ergometer. Each high-intensity training period will be 30 seconds followed by a 4-minute rest period. The participants will also perform cognitive tests (Vistorian stroop test and Fitlight trainer test) before and after the exercise.
The goal of this clinical trial is to investigate the effects of kinesthetic motor imagery training and dual-task training on cognitive and motor functions in healthy young people. The main question[s] it aims to answer are: - Kinesthetic motor imagery training and dual-task training do not affect cognitive and motor functions in healthy young people. - Kinesthetic motor imagery training and dual-task training affect cognitive and motor functions in healthy youth. - In healthy young people, kinesthetic motor imagery training is more effective on cognitive functions than dual-task training. - In healthy young people, dual task training is more effective on motor functions than kinesthetic motor imagery training. Participants will be divided into 3 groups, taking into account the inclusion and exclusion criteria. Participants in each group will be asked to fill out the sociodemographic form before starting the training. Then, initial assessments were the Motion Image Questionnaire-3 to measure motor imagery ability, and the Box and Block Test for mental stopwatch; Stroop Test to measure cognitive functions; In order to evaluate the dual-task performance, the measurement of the dual-task effect and the Berg Balance scale, which evaluates balance as a motor function, and the Y test, which is frequently used in healthy individuals, will be applied. In the balance exercises group, the participants will do the determined balance exercises 3 days a week for 6 weeks, accompanied by a physiotherapist. In the double-task training group, the participants will perform the cognitive tasks in addition to the determined balance exercises, 3 days a week for 6 weeks, accompanied by a physiotherapist. In kinesthetic motor imagery group, the participants will do the physically determined balance exercises in the first session. Participants will participate in imagery exercises, 3 sessions a week for 6 weeks. Visualization studies will be performed in a quiet environment with the eyes closed, accompanied by a physiotherapist, and whether the participants perform a real motor imagery will be examined by evaluating their autonomic functions. At the end of 6 weeks, initial evaluations will be repeated in all groups. The investigators will compare dual-task training group, kinesthetic motor imagery training group and balance exercises group to see if changes in cognitive and motor function.
The goal of this study is to investigate the effects of selective histamine 3 antagonist pitolisant on brain function and cognition in healthy individuals. The main questions it aims to answer are: 1. Does pitolisant alter functional activity in brain regions linked to reward and cognitive processing during rest or cognitive task performance? 2. Does pitolisant alter cognitive ability across a range of psychological domains, including working memory, executive functioning and emotional processing? Participants will undertake fMRI scanning in addition to a battery of tasks designed to measure cognitive and emotional processing after taking a single dose of pitolisant or placebo. Researchers will compare differences in functional activity, cognition and emotional processing across the pitolisant and placebo groups.
Dementia is a clinical disorder characterized by progressive and permanent loss of multiple cognitive functions, especially memory, at a level that affects activities of daily living. There is no pharmacologic treatment method that can change the prognosis in dementia. The methods used today are symptomatic and cause various side effects. For this reason, non-pharmacologic approaches are on the agenda in the treatment of dementia. Among these approaches, physical activity approaches such as symptomatic treatment or exercise come to the forefront due to their prognosis-slowing effects. There are also many studies showing that dementia is directly related to physical performance and frailty. Deterioration of physical performance, increased frailty, and decreased muscle strength create a vicious circle with the prognosis of dementia. In addition, patients with dementia have balance problems due to prolonged reaction time, cognitive impairment and physical problems, and the risk of falls increases. In order to prevent the risk of falls, exercise practices are of great importance. Although the effects of aerobic exercise on dementia have been examined many times in the literature, there are very few studies examining the effects of balance exercises and combined exercises. In addition, physical characteristics such as frailty and muscle weakness, which are very common in patients with dementia, have not been evaluated as a whole in studies on patients with dementia. Therefore, this study will be conducted to comparatively examine the effects of combined aerobic exercise and balance exercises on balance and falls, frailty, muscle strength, cognitive functions, and reaction time in patients with dementia.
The rapid increase in the prevalence of dementia in Taiwan poses an economic burden on healthcare systems as well as the families of the patients. Thus, how to prevent dementia is a crucial issue. Mild cognitive impairment (MCI) is defined as cognitive decline objectively and subjectively and it has been deemed as a transitional state between normal cognition and dementia. Identifying and preventing MCI can be a venue for reducing the prevalence of dementia. Sleep and physical activity are modifiable risk factors of MCI. Both factors could influence brain structure, such as the volume of the hippocampus. As a result, physical activity and adequate sleep are helpful to prevent the decline of cognitive function. In addition, sleep could regulate physical activity and change cognitive function indirectly. To our knowledge, there has been no research investigating the relationship between sleep, physical activity, and cognitive function in Taiwan. Hence, this research will aim to explore the relationship between sleep, physical activity, and cognitive function. Whether sleep and physical activity can be predictors of MCI will be investigated. We will recruit 150 participants aged above 65, who haven't been diagnosed with MCI or dementia. The measurements will include the Chinese version of The Pittsburgh Sleep Quality Index (PSQI), the Chinese Version of the Physical Activity Scale for the Elderly (PASE-C), and the Chinese version of Montreal Cognitive Assessment (MoCA). The relationship between sleep, physical activity level, and cognitive function will be analyzed by multiple linear regression and Pearson correlations. A prediction equation will be established.
The current study aims to investigate the cognitive effects of diet-induced blood glucose fluctuations on cognitive performance in healthy older adults over multiple days, taking advantage of the currently available techniques to continuously measure blood glucose levels and to assess cognitive performance in a real-life setting. In this fully decentralized study, subjects will undergo two times a three-day measurement period, where their blood glucose will be continuously measured by a minimally invasive sensor and where the cognitive performance is measured at multiple time points throughout a day using a short test battery administered on their mobile phone. In addition to receiving standardized breakfast and lunch meals, the subjects are administered a low-GI(Glycemic Index) or normal-GI(Glycemic Index) snack in the morning and afternoon.
Executive function play a key role in boosting human behavioural performance. Based on scientific literature, it is still controversial whether electroencephalography-based neurofeedback (EEG-NFB) represents an effective technique for enhancing healthy adults' executive function. This study evaluates generalized effects of 3-week EEG-NFB training, using self-regulation of the theta to beta wave ratio (TBR), on executive function in healthy adults. The subjects are an uniform group of healthy young right-handed males divided into two equal groups. The trained group (TR) performs 3-week EEG-NFB training (three sessions per week) focused on a cognitive self-regulation of TBR (to achieve the lower TBR values as beneficial cognitive effect), while the control group (CO) does not participate in the EEG-NFB training. Cognitive function are rated before and after 3-week EEG-NFB training by psychological tests: Trail Making Test (TMT, parts A and B) and the Stroop Test (ST, parts I and II). This project is important for the future development of effective EEG-NFB protocols to be used by healthy people to improve their behavioural performance.
There is great interest in improving cognitive performance and eye health as working from home becomes more prominent. Working from home as well as stress in the workplace is an increasing problem. Students and work professional can therefore benefit from improved attention and thus performance in academic and other work environments. A completely natural supplement with aronia melanocarpa extract could be a promising way to naturally improve cognitive performance
The goal of this randomized, double-blind, parallel group interventional study is to evaluate the effect of ketone bodies on healthy older adults (65-85 y) during 5 days of bed rest. The main questions it aims to answer are: Does supplementation of ketone bodies prevent the typical decline in muscle protein synthesis, muscle size, muscle function, insulin sensitivity, and muscle mitochondrial function that occurs in response to bed rest? Researchers will compare ketone supplements (KET) to an energy matched control beverage (carbohydrates and fats) to see if the ketones can rescue the decline in muscle protein synthesis rates, muscle loss, muscle function, insulin sensitivity, and mitochondrial function due to 5 days of bed rest. This may positively impact the heath of older adults subjected to bed rest.
