Study Overview

Three Conditions. One Neuroplasticity-Based Protocol.

This protocol runs across three overlapping neuropsychiatric categories: treatment-resistant depression, obsessive-compulsive disorder, and traumatic brain injury. Comorbid presentation is the norm rather than the exception: TBI with concurrent depression, depression with OCD features, and veterans carrying all three diagnoses at once.

Nearly everyone who reaches us has failed at least two prior treatment approaches for their primary diagnosis. Depression patients have failed multiple antidepressant trials; OCD patients have failed SSRIs at therapeutic doses and cognitive-behavioral therapy with ERP; TBI patients have completed standard neurorehabilitation with incomplete recovery. We have treated more than 1,000 guests since 2019 with zero serious complications recorded.

The multi-condition design reflects the clinical reality that ibogaine does not target a single diagnosis but rather operates at the level of fundamental neuroplasticity, neuroinflammation, and neural circuit reconfiguration, mechanisms relevant across this entire spectrum of neuropsychiatric conditions. Structured outcome collection began in July 2026; cohort aggregates publish at mindscaperetreat.com/outcomes once at least 20 people hold paired baseline and follow-up data, never before.

The analytics dashboard below draws live values from the clinical records system across four validated scales, PHQ-9 (depression), GAD-7 (anxiety), Y-BOCS (OCD), and a composite TBI cognitive recovery score, and renders only when the cohort holds real assessment data. These three conditions are rarely grouped in the same study, but their inclusion here is methodologically deliberate: depression, OCD, and TBI all involve pathological rigidity in neural circuit function, and tracking their responses to a shared neuroplasticity-based intervention reveals whether the therapeutic mechanism is condition-specific or operates at a more fundamental neurobiological level.

Ibogaine's BDNF and GDNF upregulation, sigma-1 receptor agonism, and temporary disruption of pathological default mode network activity create a window of enhanced neural flexibility that operates across this entire diagnostic spectrum. In depression, this disrupts self-referential rumination loops anchored in the default mode network. In OCD, it interrupts the cortico-striato-thalamo-cortical hyperdrive that sustains compulsive cycles. In TBI, it modulates post-concussive neuroinflammation and promotes axonal repair processes. The dashboard captures whether these parallel mechanisms produce measurable improvement in the same patient population within the same treatment window.

The 3 to 7 days following ibogaine administration is the window in which BDNF upregulation and default mode network reorganization are most active, which is why depression, OCD, and cognitive recovery are all scored across it rather than only at discharge. If the therapeutic mechanism is not condition-specific but operates at the level of fundamental neural circuit plasticity, three clinically distinct conditions should move inside the same pharmacological window. That is the prediction the protocol is built to test, and the instruments are scheduled to catch it either way.

Comorbid presentation is where the mechanism gets its most interesting test. The neuroinflammatory burden in TBI plausibly amplifies depressive and obsessive-compulsive circuitry dysfunction independently, so ibogaine's anti-neuroinflammatory properties would be addressing a compounding effect rather than three separate diseases. Resolving a TBI-driven neuroinflammatory cascade would then be expected to assist the depression and OCD response rather than compete with it, which is why guests carrying more than one diagnosis are scored on every relevant instrument rather than only their primary one.

Depression and anxiety are scored on two of psychiatry's most widely validated self-report instruments, and the bands matter as much as the numbers. The PHQ-9 (Patient Health Questionnaire-9) measures depression severity on a 0 to 27 scale: scores of 15 and above indicate moderately severe depression, while scores of 20 or above indicate severe depression. The GAD-7 (Generalized Anxiety Disorder 7-item scale) measures anxiety severity from 0 to 21, with scores above 15 indicating severe anxiety. Guests accepted into this protocol sit in the upper bands of both, which is the point: this is not a population that responds to any intervention.

Severe depression and severe anxiety co-occurring is clinically typical rather than unusual, because the anxious rumination the GAD-7 captures frequently accompanies and amplifies treatment-resistant depressive disorder. Ibogaine's simultaneous action on both the serotonergic and default mode network pathways driving these presentations makes it a particularly rational intervention for comorbid depression-anxiety, a profile that often requires multiple medications and years of therapy under conventional approaches.

The PHQ-9 and the GAD-7 cover the affective and ruminative dimensions of neuropsychiatric dysfunction, the subjective suffering layer. They tell only part of the neuroplasticity story. The Y-BOCS and the TBI cognitive composite cover the structural and behavioral dimensions instead: circuit-level disruptions that standard antidepressants and anxiolytics do not address, and the place where ibogaine's circuit-remodeling effects would either penetrate the deeper dysfunction underlying obsessive-compulsive and post-concussive presentations or fail to.

The mechanism that would connect depression and anxiety improvement to OCD and TBI recovery is not coincidental: it is the shared neuroplasticity pathway. Once BDNF upregulation and default mode network reorganization open a window of neural flexibility, the same biological conditions that permit affective circuit reconfiguration are simultaneously available to the cortico-striato-thalamo-cortical loops in OCD and the axonal repair processes in TBI. This is why multi-condition improvement within a single treatment window is not only possible but mechanistically expected.

Taken together, the four-metric profile is designed to answer a single question about ibogaine's breadth of action: does one intervention move a guest across clinically meaningful thresholds on instruments that measure different kinds of dysfunction. On the PHQ-9 that threshold is the step down out of the severe band, something most pharmacological interventions reach only after months of titration. On the Y-BOCS it is the step out of the severe range, where the subjective experience of obsessional intrusion and compulsive drive is meaningfully reduced rather than merely dulled.

The TBI cognitive composite is the measure we watch most closely, because no currently approved treatment produces meaningful cognitive recovery in this population. Standard TBI rehabilitation focuses on compensatory strategies and symptom management, whereas ibogaine is proposed to operate at the level of neural substrate repair through anti-neuroinflammatory and neurotrophic mechanisms that address the underlying injury pathophysiology. Convergent movement across all four metrics inside a single 14-day protocol would be the strongest available evidence for a fundamental neuroplasticity mechanism rather than any condition-specific pharmacological action, which is exactly why we will not publish a figure for it until a cohort of at least 20 people holds paired data. When one does, it goes up at mindscaperetreat.com/outcomes.

Mechanism of Action

One Mechanism. Three Conditions. Profound Neurobiological Overlap.

Depression, OCD, and TBI share a common mechanistic thread that explains ibogaine's efficacy across all three: each condition involves pathological rigidity in neural circuit function. In depression, default mode network hyperactivity locks patients into self-referential rumination. In OCD, cortico-striato-thalamo-cortical loops become trapped in compulsive cycles. In TBI, disrupted neural connectivity reduces cognitive flexibility and emotional regulation capacity.

Ibogaine's primary therapeutic action (promotion of neuroplasticity through BDNF upregulation, sigma-1 receptor agonism, and temporary disruption of pathological default mode network activity) addresses this shared mechanism directly. The result is a window of enhanced neural flexibility during which all three conditions show measurable improvement.

For TBI specifically, ibogaine's anti-neuroinflammatory properties are particularly relevant. Post-concussive neuroinflammation is a major driver of chronic TBI symptoms including cognitive fog, emotional dysregulation, and persistent headache. Ibogaine's modulation of glial cell activity and sigma-1 receptor-mediated neuroprotection targets this inflammatory cascade in ways that standard TBI treatments do not.

Clinical Protocol

Multi-Condition Ibogaine Protocol

01

Comprehensive Neuropsychiatric Evaluation

Each patient receives a full neuropsychiatric assessment tailored to their primary and comorbid diagnoses. Depression patients are assessed with PHQ-9 and MADRS; OCD patients with the Y-BOCS; TBI patients with cognitive screening, neurological history, and, where available, prior imaging. All patients complete a medication history and prior treatment timeline.

02

Medical Screening & Cardiac Clearance

Full bloodwork, EKG, and cardiovascular evaluation are mandatory for all candidates. TBI patients with a history of seizures require additional neurological clearance. Patients on psychiatric medications complete a supervised taper protocol prior to ibogaine administration to ensure both safety and therapeutic efficacy.

03

Individualized Protocol Design

Our medical director designs a personalized ibogaine dosing protocol that accounts for diagnosis mix, comorbidity burden, prior medication exposure, and therapeutic goals. Depression-primary patients, OCD-primary patients, and TBI patients receive different emphases in their protocols, including tailored supportive medications, nutritional preparation, and integration frameworks.

04

Treatment at MindScape Retreat, Cozumel

Ibogaine is administered in our medically-equipped sanctuary on Cozumel Island under continuous physician and nursing supervision. For TBI patients, neurological monitoring is enhanced. For OCD patients, the integration team prepares specific cognitive frameworks for working with obsessional content during and after the treatment experience.

05

Integration Therapy & Aftercare

Each patient departs with a diagnosis-specific integration plan. Depression integration focuses on behavioral activation and relapse prevention. OCD integration includes ERP framework continuation and reframing of intrusive thought patterns. TBI integration emphasizes cognitive consolidation exercises and somatic recovery practices. Follow-up assessments are scheduled at 30, 60, and 90 days.

Frequently Asked Questions

Questions About Ibogaine for Depression, OCD & TBI

Yes, and in many cases, patients with comorbid presentations (depression plus OCD, or TBI plus depression) experience improvement across all presenting conditions from a single treatment. This reflects ibogaine's action at the level of fundamental neuroplasticity rather than targeted receptor modulation, making it uniquely suited to complex multi-condition presentations.

We work with moderate-to-severe treatment-resistant depression, scored on the PHQ-9 (0 to 27) and the MADRS (0 to 60) at intake. We generally work with patients who have had inadequate response to at least two antidepressant trials or therapeutic courses. Mild or first-episode depression without prior treatment is not typically an appropriate indication for ibogaine.

TBI patients require additional medical evaluation, particularly regarding seizure history, current neurological status, and any cardiovascular complications from the original injury. The majority of TBI patients without active seizure disorder or significant cardiac contraindications can be safely evaluated for ibogaine treatment. Our medical director makes individual safety determinations for every TBI candidate.

All three act through neuroplasticity-promoting mechanisms, but they differ significantly in depth of action, duration of effect, and mechanism specificity. Ibogaine's unique combination of sigma-1 agonism, NMDA antagonism, serotonergic reuptake inhibition, and opioid receptor modulation produces a more comprehensive neurobiological reset than either psilocybin or ketamine alone, including direct action on OCD circuitry and TBI-relevant neuroinflammation that the others do not address.

OCD severity is scored on the Y-BOCS (0 to 40) at baseline and again through 90-day follow-up, and cohort aggregates publish at mindscaperetreat.com/outcomes once at least 20 people hold paired data. Patients typically describe a meaningful reduction in the urgency and intrusiveness of obsessional thoughts, decreased compulsive drive, and increased ability to tolerate uncertainty, the core therapeutic target of OCD treatment. These gains are typically maintained and deepened through integration therapy in the weeks following treatment.
