Research suggests that gastrodin may alleviate tau pathology by targeting the Alzheimer's risk gene FERMT2, potentially reversing the reduction in brain viscoelasticity. The therapeutic effects of gastrodin and other compounds on neurological disorders, including dementia and Alzheimer's disease, are being explored. Studies are also investigating the role of traditional Chinese medicine and the gut microbiota in the treatment of Alzheimer's disease, considering multiple therapeutic mechanisms.
