How they work
EMDR
Core mechanism: Bilateral stimulation during trauma memory processing facilitates adaptive information processing and memory reconsolidation (proposed)
Ontology: Unprocessed trauma memories stored dysfunctionally with original affect, sensation, and cognition
Ketamine-Assisted EMDR™ (KA-EMDR)
Core mechanism: Standard 8-phase EMDR protocol adapted for ketamine integration. Client self-administers low-dose sublingual ketamine (troches) at a strategically timed point during the reprocessing phases. The psycholytic dose is intended to expand the window of tolerance and enhance neuroplasticity while preserving the client's capacity to engage in bilateral stimulation and verbal processing — unlike higher-dose psychedelic approaches that impair interactive participation.
Ontology: Traumatic memories are stored in maladaptive neural networks (per EMDR's Adaptive Information Processing model). Low-dose ketamine enhances neuroplasticity and the memory reconsolidation window, allowing EMDR's bilateral stimulation to reprocess traumatic material more effectively. The pharmacological and psychotherapeutic mechanisms are proposed as synergistic rather than additive.

What each assumes — and misses
EMDR
Philosophical roots: Merleau-Ponty (body holds memory); Bion (processing/containment); Pavlov (orienting response); Shapiro (adaptive information processing — pragmatic, not philosophically derived)
Blind spots: Mechanism debate unresolved; protocol fidelity varies; may be applied to conditions beyond its evidence base
Therapeutic voice: Bring up the image and the negative belief. Notice what you feel in your body. Now follow my fingers.
Ketamine-Assisted EMDR™ (KA-EMDR)
Philosophical roots: Inherits EMDR's basis in information processing theory and memory reconsolidation science. The ketamine component draws on psycholytic therapy tradition (Passie et al., 2022) — the use of sub-psychedelic doses to enhance psychotherapeutic process rather than induce altered states as the primary intervention.
Therapeutic voice: We're going to do EMDR reprocessing the way you've experienced it before, but this time the ketamine will help your brain stay in a state where it can process the difficult material with less fear and more flexibility.
Choosing between them
EMDR (Trauma-Focused) and Ketamine-Assisted EMDR™ (KA-EMDR) (Integrative) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
