In my last article I explored how Dr. Silkworth’s classic “restless, irritable, and discontented” (RID) description in The Doctor’s Opinion (AA Big Book) might be understood through modern neuroscience. In the article (RID <-> DNS Article), I proposed that RID can be viewed as the felt experience of a Dysregulated Nervous System (DNS) – a state where reward, stress, interoceptive, autonomic, and immune systems struggle to maintain proper balance.
This week, I expanded that framework to take on a more difficult question:
- What happens when we look at depression through this same (DNS) lens?
What emerged surprised me.
Addiction and depression – usually treated as separate conditions – may actually be divergent expressions of some of the same underlying regulatory disruptions (key word being, “may”).
In some, addiction externalizes dysregulation: the system pushes outward through compulsive seeking, activation, urgency, or escape. Depression often internalizes dysregulation: the system collapses inward through withdrawal, anhedonia, shutdown, or loss of agency. Different on the surface; but underneath, the same systems often show strain:
- blunted dopaminergic and glutamatergic reward signaling
- a stress system stuck in fight-flight-freeze mode causing depletion
- distorted interoception (‘my body feels heavy’)
- reduced vagal-autonomic flexibility resulting in reduced HRV
- inflammatory signaling that drags down mood and vitality
None of this collapses addiction and depression into one disorder, and DNS isn’t a diagnosis. It’s a hypothesis-generating, transdiagnostic framework that may help us understand why these conditions so often co-occur, why they transition into one another, and why they both respond to interventions that restore regulation.
