Roots to Renewal: Traditional Chinese Medicine and Neurogenesis
In recent years, there has been growing interest in the role of adult neurogenesis—the process by which new neurons are generated in the adult brain—in both health and disease. Emerging evidence suggests that adult neurogenesis plays a crucial role in various neurological and psychiatric disorders, making it an attractive target for therapeutic interventions. Traditional Chinese Medicine (TCM), with its rich history and diverse repertoire of herbal remedies, has emerged as a promising avenue for modulating adult neurogenesis and potentially offering new treatment options for these conditions.
TCM has been shown to influence adult neurogenesis through several mechanisms. Firstly, it promotes the secretion of neurotrophic factors such as brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), and nerve growth factor (NGF). These factors are essential for the proliferation, migration, and differentiation of neural stem cells, thereby enhancing adult neurogenesis. Essentially, specific TCMs release helpful substances that encourage the growth of new brain cells, which promotes brain health. Additionally, certain TCMs have been found to increase the levels of neurotransmitters such as serotonin, norepinephrine, and dopamine, which play a role in regulating adult neurogenesis. This means that some TCMs increase certain chemicals in the brain that are important for the process of growing new brain cells.

TCMs also exert anti-inflammatory effects by inhibiting microglial activation and reducing the release of pro-inflammatory cytokines, thereby mitigating the negative impact of inflammation on adult neurogenesis. Think of it like settling down a storm in the brain. By doing this, TCM helps protect the new brain cells that are growing.
TCMs protect against neurotoxicity induced by factors such as amyloid-beta deposition in Alzheimer's disease, preserving the pool of neural stem cells and supporting adult neurogenesis. This protection helps the brain keep making new cells.
Finally, TCMs regulate several cell signaling pathways, which are involved in various stages of adult neurogenesis and survival. Studies also indicate that they help to regulate the Notch signaling pathway, promoting stem cell proliferation and inhibiting neuronal differentiation, thereby influencing adult neurogenesis.
The modulation of adult neurogenesis by TCM holds significant promise for the treatment of neurological and psychiatric disorders. By targeting key pathways and factors involved in adult neurogenesis, TCMs have the potential to promote neural repair and regeneration, improve cognitive function, and alleviate symptoms associated with these disorders.
While the evidence supporting the role of TCM in regulating adult neurogenesis is compelling, further research is needed to fully understand the specific targets and mechanisms involved to validate the efficacy and safety of TCM interventions. It is also important to note that the role of TCM should not be taken as a replacement for conventional medicine, but rather as a supplement that may hold the potential to further promote health and wellness.
