简要总结
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?
详细描述
Researchers will compare broccoli sprout extract to a placebo to evaluate their effectiveness in improving cognitive function in participants.
Participants will:
- Take dietary broccoli sprout extract or a placebo daily for 12 weeks.
- Visit the clinic at screenig, 0, 6, and 12 weeks for checkups and tests

结局指标
主要结局
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
时间窗: 12 weeks
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.
次要结局
- Change from baseline to 12 weeks in verbal learning test score(12 weeks)
- Change from baseline to 12 weeks in auditory continuous performance test score(12 weeks)
- Change from baseline to 12 weeks in Korean Mini-Mental State Examination (MMSE-K) total score(12 weeks)
- Change from baseline to 12 weeks in serum malondialdehyde (MDA) concentration(12 weeks)
- Change from baseline to 12 weeks in digit span test score(12 weeks)
- Change from baseline to 12 weeks in serum brain-derived neurotrophic factor (BDNF) concentration(12 weeks)
- Change from baseline to 12 weeks in serum superoxide dismutase (SOD) activity(12 weeks)
