Our results confirmed that the dementia marker BDNF was effective in reducing cognitive impairment on community-dwelling individuals of various ages after 4 weeks of treatment; (50–59 years; *** p < 0.001), (60–69 years; *** p < 0.001), and (70–79 years; *** p < 0.001) are shown Figure S2. The gene discussed is BDNF; the disease is dementia.
