With rates of subjective cognitive decline (SCD) and dementia rising, Traditional Chinese Medicine (TCM) is presented as a promising, multimodal strategy for supporting brain health due to its holistic, individualized approach. Cognitive decline is a complex condition linked to neurodegenerative diseases, lifestyle, and chronic inflammation. Emerging research indicates that acupuncture supports cognitive function through key neuroregulatory effects: promoting cerebral blood flow, modulating neurotransmitter levels, and reducing neuroinflammation. Human trials show that acupuncture can lead to increases in hippocampal volume and improved brain connectivity in older adults with SCD and mild cognitive impairment (MCI). Furthermore, Chinese herbal medicine offers neuroprotective support. The article highlights several botanicals: Panax ginseng (ren shen) for enhancing memory and cognitive performance; Salvia miltiorrhiza (dan shen) for cerebrovascular health and reducing oxidative stress; and Polygala tenuifolia (yuan zhi), which has shown potential in experimental models by reducing beta-amyloid plaques associated with Alzheimer's disease. The existing evidence, combined with TCM’s centuries of clinical application, strongly suggests that integrating acupuncture and herbal medicine into mainstream cognitive health strategies is a warranted and essential adjunct to conventional care.
