Ayurveda, which takes a comprehensive view of an individual's physical, emotional and spiritual conditions, attributes anxiety disorder symptoms to aggravated prana vata, a subsidiary of vata dosha which is associated with worry, anxiety and depression. Prana vata weakens the nervous system and triggers mental imbalance. It also weakens the neuro-hormonal system and nerve impulses. Ayurvedic treatment of anxiety disorder would involve curbing aggravated prana vata and increasing sattva guna, which envisages a stable and peaceful mind through self-realization and self-control, and appropriate changes in diet and lifestyle.
