Episode 3 – Mental Health, Depression & Autoimmune Disease: The Vagus Nerve Connection

by | Podcast

In this episode, Dr. Micah Yu and Dr. Melissa Mondala discuss one of the most overlooked aspects of autoimmune disease: mental health. With depression and anxiety affecting more than half of all autoimmune patients, the conversation explores the deep connection between the nervous system, trauma, inflammation, and long-term healing.

Key Points: 

  • One in two people with autoimmune disease also has depression or anxiety.
  • Mental health symptoms often appear years before autoimmune diagnosis.
  • Emotional trauma, chronic stress, and neuroinflammation can all trigger or worsen autoimmune flares.
  • The field of psycho-neuro-immunology explains how the brain, nervous system, and immune system interact.
  • Childhood trauma (ACEs) significantly increases the risk of autoimmune conditions later in life.
  • Early signs of depression and anxiety include sleep changes, appetite issues, mood swings, perfectionism, joint pain, rashes, and fatigue.

Featured Case Study:

A 60-year-old woman with long-standing rheumatoid arthritis saw dramatic improvement in pain, energy, and inflammation after focusing on nervous system regulation, sleep, and mental wellness. Her care plan included vagus nerve stimulation and lifestyle changes. Within 3 months, she was pain-free, off prednisone, and considering a return to nursing. Her recovery also positively impacted her son, who struggled with mental health issues.

Final Message:

Healing is possible — even after years of trying. When diet and medications aren’t enough, it’s time to address mental health, trauma, and the nervous system. This episode reminds us that what feels emotional is often physical, and that support, persistence, and the right tools can make all the difference.
