Filter by:The objective of the current study is to determine the acute effect of a glucose drink and a sacharose drink compared to a placebo on cognitive performance in elderly with light memory complaints. The investigators expect that the sugar containing drinks will improve memory and attentional functions. Furthermore, blood glucose response will be measured.
The purpose of this study is to determine whether modafinil is effective in the improvement of mnesic performance and executive functions of university students from high academic performance.
The purpose of this study is to investigate the effects of the dietary supplement oréVida™ (active ingredient on the basis of a culinary herb)administered twice daily in an acute study on an improvement in vigilance, attention, concentration, memory and mood in 45 healthy men and pre-menopausal women, aged 35-50 years, inclusive. oréVida™ is considered a dietary supplement, and therefore it is not an approved drug by the Food and Drug Administration (FDA). It is regulated like a food. The U.S. Food and Drug Administration does not strictly regulate herbs and dietary supplements. We do not claim that this supplement is meant to treat any ailment.
Impaired WM is a central deficit in ADHD. A computerized training program, Cogmed, has been shown to increase WM capacity in children with ADHD. It is not known whether the training improves behavior associated with classroom learning, such as remaining on-task and inhibiting off- task behavior. The aim of this study is to utilize ecologically valid measures to investigate training's effect on observable ADHD behavior in conjunction with more standard measures. Subjects will be randomly assigned to a Cogmed versus an active "placebo" condition in which the tasks do not increase in difficulty level in a double-blinded fashion. The effects of the active Cogmed versus placebo computer training will be compared on measures in children with ADHD.
To date, the relationship between omega-3 polyunsaturated fatty acids (n-3 PUFAs) in cognitively intact individuals has only been examined in a limited number of studies; it is at present unknown whether supplementation with n-3 PUFAs can improve cognitive function and mood in this population. Further to this, it still remains to be established whether a relationship exists between peripheral fatty acid status—reflective of dietary n-3 PUFA intake—and cognitive function in this population. The current study therefore aims to address this issue by exploring the relationship between serum PUFAs and specific cognitive functions in a sample of healthy adults. To this end, participants will complete a range of cognitive tasks evaluating performance across the domains of attention, memory and executive function. Self-report mood assessments will be included as secondary measures.
The goal of this study is to determine if 8-week dietary treatment with the omega-3 fatty acid docosahexaenoic acid (DHA) improves attention performance and associated cortical activity and metabolism in 8 - 10 year old males that were not breast-fed during infancy.
The purpose of this study is to determine the efficacy and safety of REMEMBER-fX (HT1001, an extract of Panax quinquefolius) in a human sample using standard clinical neuropsychological instruments and side effects rating scales.
