Why Depression May Be an Early Sign of AutoimmunityWhy Depression May Be an Early Sign of Autoimmunity
The Biology of Trauma™ With Dr. Aimie
Dr. Aimie examines how depression and autoimmunity often move together in a biological loop involving trauma, inflammation and nervous system changes. She discusses why standard antidepressants may fall short and describes body-based strategies to help shift the system towards greater safety and healing.

Depression, Autoimmunity and That Scary Feeling of Going Flat
Episode Overview
- Depression and autoimmune disease show a two-way relationship, with each nearly doubling the risk of the other.
- Early-life toxic stress can reshape the nervous, immune and endocrine systems, contributing to both depression and autoimmunity.
- Inflammation can create a “sickness behaviour” type of depression marked by flatness and lack of motivation rather than sadness.
- Serotonin-focused antidepressants may underperform when inflammatory pathways are driving depression linked to autoimmunity.
- Shifting the nervous system from survival to safety through somatic, body-based practices can open the door for further biological and emotional healing.
“Some proportion of people are sitting in a psychiatrist’s office with depression that will not respond and are in the early biology of an autoimmune process that just has not showed up on the panels.”
What drives someone to seek a life without going numb to their own struggles? This episode of The Biology of Trauma™ takes on that quiet, frightening experience of having an autoimmune diagnosis and realising the hardest symptom isn’t pain, but the sense that you’ve stopped caring about your own life. Dr. Aimie goes solo, speaking both as a medical physician and someone who has personally lived through depression before her own autoimmune diagnosis.
She challenges the usual story that depression is simply a natural emotional reaction to chronic illness. Instead, she walks you through research showing that depression and autoimmunity often move in a loop, each nearly doubling the risk of the other, and both sharing deeper biological roots.
You’ll hear clear explanations of large-scale studies, including work from Denmark and meta-analyses involving millions of people, all pointing to the same pattern: early adversity, changes in the nervous system, chronic low-grade inflammation, and then the arrival of both depression and autoimmune disease. She explains “sickness behaviour” – that flu-like flatness where nothing feels enjoyable and motivation disappears – and how this can show up long before an autoimmune condition appears on lab tests.
Rather than blaming personality or willpower, Dr. Aimie frames depression linked with autoimmunity as a biology issue, especially when antidepressants don’t do much. She describes how inflammation can undercut serotonin-based medications, why treatment-resistant depression may actually be an early sign of autoimmunity, and how survival physiology keeps the body stuck. For those in recovery or living with chronic illness, the most hopeful part is her focus on what can change.
She talks about somatic, body-based practices to create a felt sense of safety, shifting the nervous system out of survival mode, and then layering in nutritional and biological support. If you’ve ever wondered whether your “flatness” could be telling you something important about your body, this episode might help you ask better questions – and feel less alone in the process.
