Active clinical trials for "Mental Fatigue"

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 study aims at examining the influence of both physically and cognitively induced fatigue on trunk motor control on the one hand and brain activity related to movement preparation on the other hand, in healthy adult subjects. Furthermore, a comparison between the effects of both types of fatigue will be made. For this purpose a motor control task will be performed and compared before and after 3 specific interventions: i.e. a control intervention, a physical task and a cognitive task. Muscle and brain activity will be measured during each motor control task. It is hypothesised that motor control will not be altered after a control task, i.e. seated rest for 45 minutes. With regards to the physical fatigue condition, it is expected that trunk muscles will contract earlier after this task than before due to altered motor control. Cognitive fatigue is hypothesised to have similar underlying processes as physical fatigue, thus a similar earlier muscle contraction is also expected after cognitive fatigue. Lastly, as both types of fatigue are expected to induce a similar effect on motor control no significant differences between cognitive and physical fatigue are hypothesised. However, it is possible that the magnitude of this effect differs between types of fatigue, i.e. that 1 of both types has a bigger effect on motor control than the other. With regards to brain activity in preparation of a motor control task similar hypotheses are formulated: no effect of the control task on brain activity, earlier and possibly increased brain activity after both fatiguing tasks, and no differences between both types of fatigue besides a possible difference in magnitude of effect.

The aim of the study is to test a Fasting Mimicking Diet (FMD) for its efficacy on improving muscular resistance and endurance. The investigators will perform a randomized clinical trial to test the efficacy of the FMD on improving muscular strength, muscular resistance and endurance in physically active young adults (18-40 years of age). The study will include two arms: Placebo (Placebo diet) and FMD (3 cycles of 5-day fasting-mimicking diet within two months). Study endpoints will include muscular strength evaluation of lower limbs, cardio-pulmonary responses, neuromuscular function and muscle architecture. Subjects will be evaluated 4 times within 3 months: at baseline (T1), after the 1st cycle of diet (T2), 7 to 15 days after the 3rd cycle of diet maintaining baseline intensity (T3) and with re-assessment of Peak Power Output (T4).

Cognitive impairment refers to when an individual struggles to learn, concentrate, remember, or make decisions. This can be due to underlying neurological diseases (i.e. Alzheimer's disease, dementia, etc.), caused by viral illness (i.e. brain fog experienced by COVID-19 survivors) or physical trauma (i.e. concussion). Recent reports indicate that two out of three Americans experience some amount of cognitive impairment in their lifetime. There are a number of therapies that have been used to help address this condition. One of these is transcranial direct current stimulation (tDCS), which delivers sustained direct current to to the head area via electrodes. A number of studies have indicated that this form of therapy is safe and efficacious at inducing neuroplasticity and exciting neuronal activity. These factors can help improve aspects of cognitive functioning such as working memory, learning, and task performance. The purpose of this pilot study is to examine the acceptability and proof of concept effectiveness of a wireless, transcranial direct current stimulation for people with cognitive impairments.

The primary objective is to investigate the correlation between physical and mental fatigue to lower extremity force production in adults to determine if there is an association of performance output that is inhibited by mental and physical stressors that mimic sport environments that can be further investigated to determine the importance of not only physical training and exercise for athletes, but also mental and cognitive exercises with physical task to enhance performance training and rehabilitation of individuals. In adults, how does physical and mental fatigue in combination compared to those who are just physically fatigued affect average peak height in performance of five CMJ with hands on hips.

The purpose of this study is to assess the effectiveness and safety of the Alpinia galanga formulation, Theacrine formulation, and Caffeine formulation on fatigue, mental acuity, and cognitive health among overall healthy participants

The aim of this study is to demonstrate the effects of 28-days supplementation with a novel probiotic formulation on mental fatigue following a cognitive load in healthy adults. Half of the participants will receive the probiotic formulation while the other half will receive placebo.

The need for assisted-technology at home reflects some of the most serious health-related conditions faced by children with physical and developmental disabilities. 'Technology-dependent' is often used in the literature to describe children "who need both a medical device to compensate for the loss of a vital body function and substantial and ongoing nursing care to avert death or further disability". Parenting a child is stressful and challenging, and even under ideal circumstances the care of a child with complex needs requires greater than normal parenting skills. Studies have showed that parents of children whose illness require assisted-technology experience significant emotional stress, potential gaps in social support, and social isolation leading to lower quality of life, unhealthy family functioning, and negative psychological consequences. This study intends to assess the feasibility and efficacy of a tele-psychotherapy (Tele-P) intervention as a way to promote the emotional functioning of parents and to help increase the quality of life of children that are technology-dependent in the Greater Boston Area. It is hypothesized that parents who adhere to psychotherapy sessions via videoconferencing (Tele-P) will demonstrate significant reductions in symptoms of depression, anxiety and social isolation. Children of parents in the (Tele-P) condition will show significantly greater improvements in their quality of life including their physical health, mental health, family life, free time, and general life enjoyment. A randomized controlled trial is proposed in order to evaluate the feasibility and efficacy of a tele-psychotherapy intervention for parents of technology-dependent children at the Critical Care, Anesthesia and Perioperative Extension (CAPE) program in Boston Children's Hospital. This study will serve as model for social workers to perform an intervention for parent's raising technology-dependent children. This study proposes that tele-psychotherapy be a means of advocating for this underserved population.

The purpose of the study is to determine if temporarily relocating clinicians who deliver remote care using the eICU telehealth system to Sydney, Australia will lead to greater job satisfaction, reduced physiologic stress, and improve performance. Four nurses and six physicians will be sent to a site in Sydney Australia on a rotating basis to determine whether providing care during the Australian daytime is more efficient and precise than providing care during the night in the United States.

The purpose of this study is to determine which substances in cocoa produces changes in mental energy. This is a double blind study. The primary outcome measures are performance on tasks of sustained attention (serial subtract, continuous performance test and Bakan task) at pre and 90, 120 and 160 minutes post intervention, energy and fatigue symptoms (profile of mood state), and ratings of motivation to perform cognitive tasks. The assigned interventions are the following:
