Traditional Chinese Medicine views brain health not as an isolated issue, but as part of an integrated system involving the heart, kidneys, liver, spleen, qi, blood, and body fluids. The brain is nourished by kidney essence, while the heart governs mental activity and consciousness. Cognitive decline often stems from intertwined factors such as kidney essence deficiency, heart blood insufficiency, qi and blood stagnation, phlegm-dampness obstruction, and emotional strain.
In TCM, chronic conditions such as hypertension, diabetes, and high cholesterol are often associated with patterns such as liver-yang rising, spleen deficiency with dampness, and blood stasis. Therefore, protecting blood vessels and metabolism is an essential part of protecting the brain.
Practical prevention for those over 40 includes a balanced diet, regular sleep, sustained moderate exercise, emotional regulation, and proper management of chronic conditions. Rather than waiting for noticeable memory loss, the TCM approach emphasises early, daily care—nourishing the “Sea of Marrow”, calming the spirit, and ensuring the smooth flow of qi and blood—to maintain mental clarity and slow cognitive ageing.
