About this trial
This clinical trial aims to determine whether broccoli sprout extract improves cognitive function in adults with mild cognitive impairment and to assess its safety.
The main questions are:
* Does broccoli sprout extract improve cognitive function in participants? * What side effects occur when participants take broccoli sprout extract?

Trial outcomes
Primary outcomes
1
Change from baseline to 12 weeks in total Computerized NeuroCognitive Function Test score comprising verbal learning test, digit span test, and auditory continuous performance test
The change in total CNT score from baseline to 12 weeks, calculated as the sum of verbal learning test, digit span test, and auditory continuous performance test scores. Higher total CNT scores indicate better neurocognitive function across the domains of memory, attention, and sustained concentration. This composite measure assesses overall cognitive performance, where positive changes (increase in total score) indicate cognitive improvement and negative changes (decrease in total score) suggest cognitive decline.
Time frame
12 weeksSecondary outcomes
1
Change from baseline to 12 weeks in verbal learning test score
The change in verbal learning test score from baseline to 12 weeks, measuring memory and learning capacity. Higher scores indicate better verbal memory and learning ability. This assessment evaluates the ability to acquire, retain, and recall verbal information over multiple learning trials. Positive changes (increase in score) indicate improvement\*\* in verbal memory function, while negative changes (decrease in score) suggest a decline in verbal learning capacity.
Time frame
12 weeks2
Change from baseline to 12 weeks in digit span test score
The change in digit span test score from baseline to 12 weeks, measuring working memory and attention span. Higher scores indicate better working memory and attention capacity. This assessment evaluates the ability to temporarily hold and manipulate numerical information in memory through forward and backward digit recall tasks. Positive changes (increase in score) indicate improvement in working memory capacity, while negative changes (decrease in score) suggest decline in attention and short-term memory function.
Time frame
12 weeks3
Change from baseline to 12 weeks in auditory continuous performance test score
The change in auditory continuous performance test score from baseline to 12 weeks, measuring sustained attention and concentration abilities. Higher scores indicate better sustained attention and concentration capacity. This assessment evaluates the capacity to maintain focused attention and respond appropriately to auditory stimuli over an extended period. Positive changes (increase in score) indicate improvement in sustained attention function, while negative changes (decrease in score) suggest decline in concentration and vigilance capabilities.
Time frame
12 weeks4
Change from baseline to 12 weeks in Korean Mini-Mental State Examination (MMSE-K) total score
The change in MMSE-K total score from baseline to 12 weeks, providing a brief assessment of global cognitive function. Higher scores indicate better global cognitive function. This standardized instrument evaluates orientation, attention, memory, language, and visuospatial abilities. Positive changes (increase in score) indicate improvement in overall cognitive status, while negative changes (decrease in score) suggest decline in cognitive function.
