§ 003 / Treatment · Evaluation-first

We'll tell you
honestly if this
can help.

Neurologic and complex-condition programs are the most consequential work we do. And the most uncertain. We run a long evaluation before we treat, and we decline more applicants than we accept. If we think the honest answer is "not this therapy," we will say so.

§ 003.1 / What we tell you first

Neurologic cell therapy
is real, partial, and
still being understood.

There is credible evidence that mesenchymal stem cells can modulate neuroinflammation and, in specific conditions, support function. There is not yet credible evidence that they reverse established neurodegeneration, regrow myelin at scale, or restore lost neurons in a clinically meaningful way.

We operate in the window between those two statements. For some patients (with the right condition, the right disease stage, and realistic expectations) that window is worth entering. For many, it isn't.

Everything below is written assuming you want the real picture, not the marketing one.

§ 003.2 / Candidacy

Conditions we consider.
And ones we don't.

We do not treat every neurologic diagnosis. Below is where we believe the current evidence supports cautious intervention, and where it clearly does not. This list changes as data matures.

Consider · case-by-case

We may accept

CNS · inflammatory

Relapsing-remitting MS (select cases)

Stable disease-modifying therapy, documented active inflammation, treating neurologist willing to co-manage. Not a DMT replacement. A potential adjunct.

Stage
Early / active
Likelihood
Low–moderate
PNS · post-viral

Post-COVID small-fiber neuropathy

Biopsy or QSART-confirmed, symptoms < 24 months, failed standard care. We have modest but consistent signal here, across patient-reported and autonomic testing.

Stage
Subacute
Likelihood
Moderate
Autonomic

POTS & dysautonomia (inflammatory)

Post-infectious or autoimmune phenotype, failed tilt-table directed therapy. We stratify aggressively. The label covers very different biology.

Stage
Any
Likelihood
Low–moderate
CNS · vascular

Chronic post-stroke deficit

6–36 months post-event, plateaued on standard rehab, stable imaging. Modest functional signal in distal limb control for a subset of patients.

Stage
Chronic / plateaued
Likelihood
Low
Decline · as of 2026

We do not accept

Motor-neuron

Late-stage ALS / MND

We decline late-stage applicants where structural loss is advanced. Evidence does not support meaningful functional benefit at that stage. Early-to-mid ALS is considered separately, for quality-of-life support only, never framed as disease-modifying or a cure.

Cortical · advanced

Advanced Alzheimer's or FTD

No current protocol can restore established cortical loss. Early-stage, well-characterized patients are occasionally considered in research contexts only. Never as a billed treatment.

Spinal · acute

Acute spinal-cord injury

Acute SCI belongs in trial protocols at Level-1 centers, not in a private clinic. Chronic cases > 12 months post-event, with stable imaging, we discuss. Individually, skeptically.

Unrealistic expectation

"Regrow brain" requests

We will not sell hope that isn't supported. If the intake form describes expected outcomes we know are unreachable with current cell therapy, we end the process there. Candidly.

§ 003.3 / Evaluation

A 2–3 week evaluation,
before any decision.

Neurologic cases demand more than a blood panel and a consult. Every applicant we take past intake goes through a multi-disciplinary review. We say yes, no, or "come back when X changes." We'll tell you which.

§ 003.4 / Protocol (if accepted)

What treatment
looks like, for accepted patients.

Neurologic protocols are tailored. Dose, route, and cadence depend on condition and disease stage. Below is the common architecture. Specifics live in your written plan.

Source
Allogeneic UC-MSCs, P3 expansion
Typical dose
100–300M cells per session
Delivery
IV + intrathecal (condition-dependent)
Sessions
3 over 12 months
Re-evaluation
Every 90 days
Co-management
Required with treating neurologist
Exit criteria
Pre-defined, written
01 / Dose one

First treatment & observation

IV (and IT where indicated) under attending supervision. Short inpatient window for intrathecal cases. Functional re-test at day 14 and day 45.

1–2 nights on site · post-dose labs included
02 / 90-day gate

First decision point

We re-run your functional battery and compare to baseline. If the delta is below our pre-agreed floor, we pause. No automatic dose two.

Written assessment · accept / pause / stop
03 / Dose two

If signal is present

Second treatment at 4–6 months. Dose adjusted on response. Same observation protocol, same re-test cadence.

Conditional on gate 01
04 / 180-day gate

Second decision point

Repeat full battery. The question we answer: is continuation doing something we can defend in writing? If not, we stop and say so.

Written assessment · shared with your neurologist
05 / Dose three + exit

Consolidation & handoff

Final treatment for responders. Comprehensive handoff package to your treating neurologist: all data, all trajectories, everything we'd want if we were on their end of the chart.

§ 003.7 / Fit

Before you apply,
a self-check.

We would rather lose an application at this stage than at the written-decline stage four weeks later.

Likely a fit

You might be
right for this.

  • You have a specific diagnosis, on the conditions list above, with imaging and records to match.
  • You are stable on disease-modifying therapy and have a neurologist willing to co-manage.
  • You understand this is unlikely to be curative, and you are choosing to try anyway, eyes open.
  • You can commit to a 12-month measurement plan, including two in-person re-evaluations.
  • You want a clinic that will tell you to stop if the data says to stop.
Likely not

This probably
isn't for you.

  • You have been told by multiple clinicians that your condition is terminal and near end-stage.
  • You're looking for a protocol to reverse established neurodegeneration or regrow cortex.
  • Your treating physicians are unaware of this consultation.
  • You cannot return for re-evaluation or coordinate ongoing care locally.
  • You are looking for certainty, and cannot operate inside a response rate that is meaningfully less than complete.
§ 003.8 / Investment

What an accepted
program costs.

Prices below apply only after acceptance. The evaluation itself is free, as noted above.

Plan · Single dose

Diagnostic dose

One treatment, full baseline capture, 90-day re-evaluation. Used rarely, and usually when we want to test responsiveness before committing to a full program.

Individualizedafter eval
Plan · 12-month program

Neurologic protocol

Three doses, full evaluation, quarterly re-measurement, multi-disciplinary review throughout. Includes written handoff to your treating neurologist at program end.

Individualized/ program
Policy · Partial refund

If we pause you at the 90-day gate

If we stop your program at the first decision point because the data doesn't support continuation, you receive a refund of the undosed balance. We want that decision to be easy for us to make.

§ 003.9 / Questions

Neuro-specific
questions.

Q.01 Why are you so selective about who you accept?
Because neurologic biology is harder, the financial commitment is larger, and the cost of selling false hope is measured in something other than dollars. Even among carefully chosen patients, not everyone responds. Accepting everyone who wanted treatment would erode the honesty of our outcomes, and the trust patients place in our accepting them.
Q.02 What does "intrathecal delivery" mean, and is it required?
Intrathecal means injection into the cerebrospinal fluid through a lumbar puncture. It puts the cells closer to the CNS than IV alone. For some CNS conditions we recommend it; for peripheral or autonomic conditions, IV alone is appropriate. The decision is part of your written plan, not a pre-sold add-on.
Q.03 Do you coordinate with my neurologist?
For neurologic programs, yes. Co-management is required, not optional. If your neurologist is unwilling to be looped in, we will not take the case. Every handoff document is designed to be the kind of record we'd want to receive if we were the one managing you long-term.
Q.04 What happens if nothing measurable changes in my first 90 days?
We stop. You receive a pro-rated refund of the undosed program balance and a written summary of what we measured, what we expected, and what we observed. The second dose is conditional on meeting the pre-agreed response floor, written into your plan before dose one. Exactly to prevent the dynamic where a clinic keeps dosing a non-responder.
Q.05 Is this a clinical trial?
No. This is a physician-led treatment program operating under COFEPRIS regulation in Mexico. We measure outcomes rigorously and publish them, but we are not an IRB-registered trial site. If a trial exists for your condition at a major center and you might qualify, we'll tell you. Sometimes that's the honest recommendation.
Q.06 What's the downside I should know about?
Three. First: there is a real chance that the treatment does not produce measurable change. You pay for the evaluation and program regardless, minus refund policies above. Second: intrathecal dosing carries the standard LP risk profile (headache, rare bleeding, very rare infection). Third: unlike joint patients, neurologic patients often face the slow, ambiguous grief of "did it work?" We structure measurement to cut through that. Not every patient wants that level of cold clarity, and it matters to know that going in.
§ 003.10 · Apply

Start with
the evaluation.

Not a sales call. A records review, a screen, and a multi-disciplinary opinion. If we accept you, we'll tell you what to expect. In writing. If we don't, we'll tell you why, and where we think you should look next.
