In vata-type apasmar, increased Vata goes to majja dhatu causing abnormal brain waves. Which dhatu is involved?

• A. Rasa dhatu
• B. Majja dhatu
• C. Mamsa dhatu
• D. Shukra dhatu

Answer: (B)

In vata-type apasmar, the key idea is that aggravated Vata disrupts the nervous system by affecting the tissue that forms and supports brain and nerves. Majja dhatu is the nervous tissue that includes brain-related structures and is closely tied to consciousness, perception, and neural impulses. When Vata increases and travels to majja dhatu, it disturbs its function, leading to abnormal brain activity described as abnormal brain waves.

The other dhatus relate to different body systems—Rasa dhatu to plasma and nourishment, Mamsa dhatu to muscle tissue, and Shukra dhatu to reproductive fluids. They are not the primary mediators of nervous-system disturbances in this context, so majja dhatu best explains the brain-wave abnormality seen in vata-type apasmar.
