NCT07334366

Brief Summary

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?

Outcome Measures

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.

    12 weeks

Secondary Outcomes (7)

  • Change from baseline to 12 weeks in verbal learning test score

    12 weeks

  • Change from baseline to 12 weeks in digit span test score

  • 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
