grey matter and white matter

Question

Doctor, I’ve recently been learning more about brain health, and I came across the terms grey matter and white matter. I know that grey matter contains the cell bodies of neurons and is involved in muscle control, sensory perception, and decision-making, while white matter consists of nerve fibers that connect different areas of the brain. I’m curious about how these two parts of the brain work together, and what could happen if either is damaged.

I’ve heard that conditions like multiple sclerosis and Alzheimer’s disease can affect grey matter and white matter, leading to cognitive decline or motor issues. Could an imbalance in the doshas be a factor in these conditions, particularly Vata dosha, which governs communication in the nervous system? Could Vata imbalance contribute to a deterioration of cognitive function, resulting in issues with grey matter and white matter?

What Ayurvedic herbs or treatments can support the health of grey and white matter, especially as we age? I’ve heard that Brahmi and Ashwagandha can help with brain health—could these herbs support the regeneration of grey and white matter? Are there dietary changes that can improve my cognitive function and promote the health of these brain tissues?

I’d appreciate your Ayurvedic guidance on how to protect and enhance brain health and function, especially in relation to grey matter and white matter.

In Ayurveda, brain health is closely linked to Majja Dhatu (nervous tissue) and the balance of Vata dosha, which governs neural communication. Grey matter, responsible for processing information, and white matter, which facilitates connectivity, both require proper nourishment to function optimally. An aggravated Vata dosha can lead to cognitive decline, poor memory, and neurodegenerative conditions like Alzheimer's and multiple sclerosis. Ayurvedic herbs such as Brahmi, Ashwagandha, and Shankhpushpi help nourish the nervous system, enhance cognitive function, and support nerve regeneration. Medhya Rasayanas (brain-rejuvenating herbs) like Gotu Kola and Jyotishmati are also beneficial. A diet rich in ghee, soaked almonds, walnuts, and warm, unctuous foods can strengthen brain tissues. Avoid excessive stress, irregular sleep, and overstimulation, as these can aggravate Vata. Regular Abhyanga (oil massage) with Brahmi oil, Nasya therapy (application of medicated oils in the nose), and meditation help maintain a balanced nervous system and protect both grey and white matter as you age.
