In people with cognitive complaints, we are unsure whether ginkgo improves global clinical status at six months, and it may be associated with an increased risk of AEs at three months. Ginkgo probably has no benefit at three months for cognition in multiple sclerosis; numeric data on AEs were unavailable, but studies did not suggest concerns. In people with MCI, ginkgo probably has little or no effect at six months on global status, cognition, or ADLS. There may be little or no difference in AEs, and there is little or no difference in SAEs, at up to 12 months. In people with dementia, there may be small to moderate benefits at six months for global status, cognition, and ADLs. There is probably little or no difference in AEs at up to 12 months, and there may be no difference in SAEs.
Wieland et al. (Thu,) studied this question.
