Start with what life feels like now
What if symptoms began after an illness or exposure?
We help people with symptoms following an exposure or illness by reviewing their history and current findings so that they can make informed choices about getting back to everyday life.
How we look at the whole picture
You noticed a change after an illness or exposure, but you still have questions about what is happening now.
Fatigue, sensitivities or trouble thinking may be disrupting work, home life and plans.
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.
In their own words
We understand your experience of Toxic (Mold, Lyme)
People often describe it in their own words long before anyone gives it a name. If one of these sounds like you, you are in the right place.
“My symptoms started after we moved into a water-damaged home or building, and they improve when I’m away from it.”
“I was treated for Lyme disease but the brain fog, fatigue, and nerve symptoms never went away.”
“I’ve been told mold illness isn’t real, or that my Lyme is cured, and yet I’m still sick.”
“Every specialist treats one symptom and no one is looking at the exposure.”

The 7 Domains of Recovery™
Your symptoms may belong in the same conversation.
An exposure history is one part of the picture. We also consider immune function, energy, cognition and the other domains, including alternative explanations for symptoms.
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.

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 timeline, previous testing and care, and any ongoing exposure concerns. The next assessments depend on what remains uncertain.
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.

The nervous system injured by the environment

What is happening in your nervous system
An environmental trigger sets off an immune response that does not switch off. In mold-related illness, the working model is that biotoxins from water-damaged buildings drive persistent innate immune activation in susceptible people, a pattern described as chronic inflammatory response syndrome (CIRS). In post-treatment Lyme disease syndrome, symptoms persist after antibiotic treatment, and the leading explanations include residual immune activation, autonomic injury, and tissue damage from the original infection. In both cases the nervous system carries the cost. Sustained neuroinflammation reduces network efficiency in Domain 1, immune signaling disrupts autonomic regulation in Domain 2 and produces orthostatic intolerance and heart rate swings, and the psychiatric overlay of anxiety, depression, and cognitive change follows. Domain 3 (Immune Function & Neuroinflammation) is the primary site. Domain 7 (Life, Relationships & Environment) matters as much, because if the exposure continues, no therapy can outpace it. These diagnoses are contested in conventional medicine. CIRS and chronic Lyme are not universally accepted as defined entities, and diagnostic testing for both is debated. Neuregen tells you that plainly, and builds the plan around the mechanisms that can be measured and treated.
Domains most involved:
Every plan starts from the same map: the 7 Domains of Recovery.
How it fits your plan
Exposure assessment comes first. If you are still living or working in the environment that made you ill, remediation or relocation is part of the plan, and we say so before recommending any therapy. Conventional medical management stays in place: active infection is treated by infectious disease, and Neuregen does not replace that. Our lane is what persists afterward. A functional neurology and autonomic evaluation establishes the domain map. The most established tools are applied first: neurorehabilitation, autonomic retraining, and integrative psychiatry for the mood and cognitive overlay. A stellate ganglion block may be used where autonomic dysregulation is prominent. Therapeutic plasma exchange for mold-related neurologic illness and EBOO are offered as investigational adjuncts, with explicit informed consent and no outcome guarantee. The Blood Rehabilitation hub explains each of those in detail. Which laboratory testing is ordered, and how it is interpreted, is decided at evaluation and discussed with you directly.
The timing of symptoms, possible exposures, prior diagnoses and treatments all belong in the evaluation. We consider immune, autonomic and daily-life factors together without assuming that an exposure explains every symptom or that a particular treatment is needed.
When rehabilitation alone gets you most of the way but a barrier remains, we can medically escalate inside the same clinical relationship instead of referring you out.
We review your history, explain the findings, agree on next steps and check how you respond.
Potential Therapies
We use established medicine where it works, and emerging medicine where it makes sense.
These are options to discuss after evaluation, not a predetermined treatment plan. Each label refers to the condition or indication described beside that therapy; evidence can differ for another use. An evidence label does not mean FDA approval.
- Environmental & Exposure AssessmentEvidence: Established
The prerequisite: identify the driving exposure and plan remediation before any advanced therapy.
- Conventional Medical ManagementEvidence: Established
Active infection stays with infectious disease; Neuregen coordinates rather than replaces.
- Functional Neurology AssessmentEvidence: Established
Baseline evaluation of network, autonomic, and immune-driven dysfunction.
- NeurorehabilitationEvidence: Established
Rebuilding the Domain 1 networks worn down by sustained neuroinflammation.
- Autonomic Regulation & RetrainingEvidence: Established

- Integrative PsychiatryEvidence: Established
For the anxiety, depression, and cognitive overlay that accompanies environmentally driven neuroinflammation.
- Stellate Ganglion Block (SGB)Evidence: Preliminary
Where autonomic dysregulation is driving the picture; one step inside the program.
- Therapeutic Plasma Exchange (mold/Lyme)Evidence: Investigational
For mold-related neurologic illness; early-stage evidence, offered with informed consent.
- EBOOEvidence: Investigational
Metabolic and neuroinflammatory support; investigational adjunct, not standalone.
- Complex Immune & Neuroinflammatory PathwayEvidence: Established
The symptom-pattern entry point when the exposure has not been identified.
Where the evidence stands
Evidence varies by therapy and by condition. Each therapy on this page carries its own evidence label for this condition, from established to investigational.

Is mold illness a real diagnosis?
The symptoms are real. The label is contested. Chronic inflammatory response syndrome (CIRS) is a working model for how biotoxins from water-damaged buildings drive persistent immune activation in susceptible people, and it is not universally accepted in conventional medicine. Neuregen tells you where the evidence stands, evaluates the immune and neurological mechanisms that can be measured, and treats those.
Does Neuregen treat active Lyme disease?
No. Active infection is managed by infectious disease physicians, and Neuregen coordinates with them rather than replacing them. Our lane is the neurological and autonomic symptoms that persist after treatment, sometimes called post-treatment Lyme disease syndrome.
Is therapeutic plasma exchange proven for mold or Lyme?
No. TPE is an established therapy for classic autoimmune neurologic disease, but for mold-related neurologic illness it carries early-stage evidence and is labeled investigational at Neuregen. It is offered as an adjunct within a broader program, with explicit informed consent and no outcome guarantee, and only after exposure assessment and the more established tools are in place.
What if I am still living in the exposure?
Then that is the first problem to solve. Domain 7 covers your environment for a reason: no therapy can outpace an ongoing exposure. Remediation, relocation, or a change of workplace becomes part of the plan, and we say so before recommending anything else.
How does this differ from the Immune flagship and the Complex Immune pathway?
The Immune flagship covers immune dysregulation affecting the nervous system in general, including autoimmune-neurologic, MCAS, and post-viral presentations. The Complex Immune pathway is the symptom-pattern entry point for people without a clear trigger. This page is for people whose illness began with an identifiable environmental exposure, mold or Lyme most often, and who search in that language.
