You've Already Tried the Standard Path. This Is What Comes Next.
You have tried to feel better. Maybe medication helped for a while, then stopped. Maybe it never helped enough. Maybe your mood lifted but your energy, sleep, focus, and motivation never followed it back.
Treatment-resistant depression means depression that hasn't improved enough after at least two adequate antidepressant trials, at therapeutic dose, for sufficient duration. That definition matters: the problem was never lack of effort. It was that standard treatment stopped at the point where most of the actual biology was never examined.
"Being told your depression is treatment-resistant is not a verdict. It's a signal that the next step needs a different strategy than the last one. So we prepare the terrain first, apply the catalyst into a system that's actually ready to respond, then protect and extend the gain once it's made."

Depression Has Up To Six Measurable Failure Mechanisms
Before we talk about treatment, we look for which of these are active in you, because two people with the identical diagnosis can be failing for entirely different biological reasons.
1
Neuroinflammation & Kynurenine Activation
Inflammatory signaling shunts tryptophan away from serotonin and into a neurotoxic metabolite (quinolinic acid) that interferes with the same receptors plasticity-based treatments depend on. Serotonin synthesis can fail even on an SSRI, because the problem is substrate, not reuptake.
2
HPA-Axis Dysregulation & Hypercortisolism
Sustained cortisol suppresses BDNF and alters the receptor context that governs how well the brain forms new connections. A brain on high cortisol is fighting itself before treatment begins.
3
Thyroid Insufficiency
Low free T3, even with a normal TSH, quietly suppresses BDNF and reduces serotonin-receptor density. It's common in TRD, and standard TSH-only screening does not catch it.
4
Sleep & Circadian Disruption
Deep, slow-wave sleep is the specific window when the brain consolidates new connections and clears neurotoxic waste. Destroy that window and plasticity-based gains fade within days.
5
Medication Interference
Certain medications, most notably long-acting benzodiazepines and some mood stabilizers, block the exact cellular cascade plasticity-based interventions rely on. A specific, identifiable, correctable conflict.
6
Neuroplasticity Readiness (BDNF/TrkB Deficit)
Chronic depression depletes the brain's own growth-factor receptor density. Without enough BDNF substrate and TrkB sensitivity, a plasticity-triggering intervention can't fully take, no matter how well it's delivered.
Two systems that connect them
Autonomic Nervous System Regulation
Sustained sympathetic dominance and low heart-rate variability directly impair the brain's capacity for recovery and repair.
Hormonal Substrate
Thyroid, reproductive, and adrenal hormones shape mood, cognition, and neuroplasticity together, not in isolation.
Why "Resistant" Doesn't Mean "Hopeless"
A Staged Protocol, Not A Grab Bag
You are never handed every intervention at once, and never given a catalyst before the terrain is ready. Sequence is not a formality here, it's the mechanism.

The Modalities We Use
How We Find Your Drivers
Comprehensive baseline labs (in-office, first visit)
Inflammatory markers including the kynurenine ratio, a full HPA-axis cortisol curve, a complete thyroid panel including free T3 (not TSH alone), serum BDNF, and genetic and nutrient markers relevant to methylation and treatment response.
Paired brain measurement
Brain Gauge and WAVi EEG completed together at your first visit. Neither test alone diagnoses a disorder or dictates treatment; together they sharpen the picture your labs and history have started to build.
Ongoing outcome tracking
Depression and anhedonia scales, sleep quality, HRV trends, and medication effects are tracked at defined intervals, and the plan is refined, simplified, or stopped based on what your own response shows.
Working Alongside Your Care
What This Is Not
F.A.Q.
Depression that hasn't improved enough after at least two adequate treatment trials at therapeutic dose and duration. We review your actual treatment history in detail rather than relying on the label alone.
No. It means the next step needs a different strategy, one built around the biological drivers standard treatment never tested for.
No. We review your full history, current medications, safety profile, and biological driver pattern first. Ketamine, when it's the right tool, is introduced only once your evaluation and substrate preparation support it.
No. Medication may be part of your plan, but we also directly address sleep architecture, autonomic recovery, HPA-axis and thyroid status, neuroinflammation, and neuroplasticity substrate.
Yes. Baseline labs are drawn in-office at your first visit, and Brain Gauge and WAVi EEG are completed together the same day.
There's no universal timeline, and we won't manufacture one to make this page sound better. Response depends on your specific history, biology, and treatment sequence.
Often, yes. We coordinate with your existing care team with your permission. Don't stop or change a prescribed medication without speaking to the clinician who manages it.
No. Peak Body and Mind is not an emergency service. If you may harm yourself or someone else, call or text 988, call 911, or go to the nearest emergency department.
You are not a failed treatment history.
You are a person whose symptoms deserve a better map. We test for the biological drivers standard treatment never examined, prepare the terrain, and build a staged plan around what we actually find in you.
