简要总结
The primary purpose of this study is to evaluate the impact of a novel, neuro-protective and neuro-restorative dietary supplement (Braini®) on standardized memory and cognitive performance parameters. The principal active ingredients in the Braini® supplement have been commercially-available since at least 2015 or have achieved FDA new dietary ingredient notification (NDIN) in 2018, with no adverse events reported to the FDA.
A 28-day randomized, double-blinded, placebo-controlled dietary supplement study will be conducted with a cohort of younger and a cohort of colder adults to achieve the purpose of this study. The research team hypothesizes that Braini® will improve standardized performance scores measured by CNS Vital Signs standard memory and cognitive performance assays more effectively than placebo.
详细描述
The number of people affected by cognitive decline continues to rise as the US population ages. A recent report indicates that this decline can be seen as early as age 45. Optimizing cognitive function during adulthood is a key mechanism to combat cognitive decline as one reaches older adulthood.
Recent advances in cognitive wellness management have shown that tailored diet and lifestyle regimens that factor in various biomarkers and proclivities signaling cognitive decline (e.g. family genetics) can cause a person with a declining MOCA (measure of cognitive ability) score to restore or achieve an improved MOCA score.
A number of clinical trials have studied nutraceutical ingredients for improved memory enhancement and/or cognitive performance. While the individual ingredients are already well-utilized in commerce globally, the Braini® formulation is novel, harnessing synergistic effects seen in a new in vitro human neural cell challenge study carried out in South Korea by the study sponsor. In this study a series of independent in vitro (cell line) tests of the active nutraceutical constituents that comprise the Braini® dietary supplement product line were performed. The tests follow current peer-reviewed published methods for assessing the effects of biologically active compounds on human neuronal cells. The in vitro study showed a significant improvement in cell viability and reactive oxygen species (ROS) inhibition using the Braini® compounds.
Based on existing published science supporting the neuroprotective role of the Braini® formulation, this supplement may be useful and to improve cognitive function and health. Based on studies conducted outside the United States, the research team hypothesizes that orally ingested Braini® taken as directed (2 x 525 mg powdered capsules per day), will demonstrate superior improvements in standardized cognitive performance assays. MOCA scores will be used for screening patients. The research team aims to conduct a randomized, placebo-controlled, double-blinded dietary supplement study to evaluate this hypothesis among a cohort of younger and a cohort of older healthy adults.

盲法说明
Participants and study personnel will be blinded to group assignment. Study personnel will receive 24 bottles each of either "active" or "placebo" product from the supplier. The bottles would be numbered sequentially from 101 to 148 for the younger cohort and 201 to 248 for the older cohort. Within that sequence, randomized blocks of 4 bottles each would be filled with either "active" or "placebo" product, for a total of 12 blocks. The bottler will not reveal to anyone which bottles got filled with which type of product until after the conclusion of the trial. Except for having a different sequential number on the label, the bottles will be indistinguishable.

CNS Vital Signs test battery
时间窗: 28 days
The CNS Vital Signs test is a computerized neuropsychological battery that includes seven sub-tests designed to screen cognitive abilities. The Verbal Memory Test involves immediate and delayed recognition for words presented on the screen. The Visual Memory Test involves immediate and delayed recognition of geometric figures. The Finger Tapping Test involves rapidly press the space bar. The Symbol Digit Coding Test involves typing numbers that correspond to different symbols presented on screen. The Stroop Test contains three parts that involve responding to words and colors. The Shifting Attention Test involves matching geometric objects either by shape or by color. The Continuous Performance Test is a 5-min sustained attention test that involves responding to the target stimulus. Results are given as normed domain scores for Memory, Psychomotor Speed, Reaction Time, Complex Attention, and Cognitive Flexibility each with a mean score of 100 and SD of 15
