Start with what life feels like now

How can immune concerns overlap with nervous-system symptoms?

We help people with unpredictable reactions, fatigue and brain fog by examining immune symptoms alongside other systems so that they can work toward a day that is easier to plan.

How we look at the whole picture

A meal, a smell or an ordinary outing can leave you feeling unwell, and the pattern is difficult to explain.

You may be tracking triggers while also dealing with poor sleep, fatigue or trouble thinking clearly.

You do not need to know which treatment to ask for. Start with what has changed and what you want to be able to do again.

The 7 Domains of Recovery™

Your symptoms may belong in the same conversation.

Immune symptoms can coexist with changes in energy, autonomic responses and concentration. We look across the seven domains without assuming that one label explains everything.

Neuregen's proprietary 7 Domains of Recovery framework organizes that conversation around seven connected parts of your life and health. We consider all seven, then focus the evaluation on the questions your history raises.

Explore our clinical framework

1Brain function & neural networks
What has changed in your memory, concentration, balance or sensory tolerance?
2Autonomic & nervous system regulation
What happens when you stand, move, rest or encounter stress?
3Immune function & neuroinflammation
What immune history, reactions or symptoms need a closer look?
4Brain energy & metabolic health
What affects your energy through the day and after activity?
5Structure, stability & body-to-brain signals
How do pain, posture, movement and stability affect what you can do?
6Psychological flexibility & behavioral recovery
How are mood, stress and patterns of coping affecting your day?
7Life, relationships & environment
What demands, relationships and support shape your recovery?

A plan starts with the things you want to do again.

We review the timing of symptoms, suspected triggers, prior diagnoses and current care. Testing is chosen to answer specific questions rather than adding a standard panel for everyone.

01
Tell us what you want your life to look like
We start with what has changed, what you have tried, and the activities you most want to return to.
02
Answer the questions the history leaves open
We review prior reports and select relevant assessments. You should understand what each assessment is meant to clarify.
03
Agree on the priorities and the first steps
We discuss the findings, possible approaches, costs and practical constraints. The plan sets an order that fits your situation.
04
Check what changes and adjust together
We compare your response with the starting point, including daily function. If something is not helping, we discuss what needs to change.

Only then do we discuss which therapies, if any, belong in your plan. The choice depends on the findings, the evidence, your preferences and how you respond.

Domain 3 of 7

Immune Function & Neuroinflammation

Calming immune overactivation and central nervous system inflammation

Book a Strategy Consultation 866-999-1177

What this domain covers

The key question: Is the immune system in a pro-inflammatory state?

Addresses cytokines, mast cell activation, autoimmunity, and persistent neuroinflammation. Chronic low-grade inflammation damages neural pathways and causes severe brain fatigue.

Conditions this domain leads

Signs this domain may be involved

Post-viral inflammation, MCAS-like patterns, autoimmunity, elevated cytokines, chronic fatigue syndrome.

How Neuregen assesses and treats it

How we label evidence

Each grade describes the evidence for a particular treatment and use. It does not guarantee an outcome or establish regulatory approval.

Level 1
Evidence: Strong
Multiple high-quality studies consistently support meaningful benefit for this use. Results are unlikely to change substantially with additional research.
Level 2
Evidence: Moderate
Good clinical evidence supports benefit, but important uncertainty remains about magnitude, patient selection, long-term outcomes, or generalizability.
Level 3
Evidence: Emerging
Early clinical studies suggest potential benefit, but the evidence is not yet strong or consistent enough for confident conclusions.
Level 4
Evidence: Preliminary
Evidence is limited to small studies, case series, retrospective data, or indirect clinical evidence. Benefit remains uncertain.
Level 5
Evidence: Investigational
There is biological rationale or very early clinical evidence, but efficacy for this use has not been established.

Some care pages also use Established to describe an established clinical use. That label is not an automatic Level 1 or Level 2 rating; the strength of evidence must be reviewed for the specific indication.

Promising does not mean proven. Your clinician considers the indication, alternatives, risks and your circumstances before recommending care.

Watch the explainer

Narrated explainer for Domain 3: immune overactivation and neuroinflammation, the question Neuregen asks, and the goal of immune equilibrium.

What recovery in this domain looks like

Quenched microglial activation, balanced cytokine profiles, and immune system equilibrium.

Treatments that may be used

Specific interventions depend on your assessment findings and are always directed by our clinical team.

Frequently asked questions

What is neuroinflammation, and why is it relevant to recovery?

Neuroinflammation refers to chronic immune activation in the central nervous system. Persistent low-grade inflammation damages neural pathways and contributes to severe brain fatigue, slowing or blocking recovery.

What does Domain 3 address?

Domain 3 addresses cytokine activity, mast cell activation, autoimmune patterns, and persistent neuroinflammation affecting brain function.

What conditions are associated with this domain?

Domain 3 leads for MCAS and mast-cell dysregulation, mold and environmentally associated illness, and Long COVID and ME/CFS: the cluster where single-specialty care most often stalls and where plasma exchange and EBOO have their strongest rationale. It also covers post-viral inflammation, autoimmunity, and elevated cytokines.

What peptides does Neuregen use in this domain?

Neuregen uses specific neuroprotective peptides — including Cerebrolysin, BPC-157, Semax, and Selank — that can cross the blood-brain barrier to support neural repair and reduce microglial hyperactivation.

What does recovery in this domain look like?

Recovery aims for quenched microglial activation, balanced cytokine profiles, and an immune system in equilibrium.

How does Domain 3 connect to the others?

Immune and inflammatory signals affect every other domain. Neuroinflammation worsens cognitive function (Domain 1), disrupts autonomic tone (Domain 2), and impairs cellular energy production (Domain 4).
