Consulting & Education for MCAS, POTS, & Nervous System Dysregulated Conditions

If you live with MCAS, POTS, Long COVID, or similar conditions and your testing looks normal, but you still feel unwell, you’re not imagining it — your body is reacting.

Welcome to New Leaf Neuro

Many people living with MCAS, POTS, Long COVID, or nervous system dysregulation feel caught in a cycle of flares, partial improvement — relapse, especially when medical testing appears normal but you clearly do not feel normal.

Common experiences include a racing heart, dizziness, food or chemical sensitivities, internal vibration, a hung-over or unwell feeling, brain fog, panic, anxiety, asthma-like symptoms, skin reactions, gastrointestinal issues, and fatigue, to name a few. Although these symptoms may seem unrelated, they often follow recognizable patterns.

What is often missed is that these conditions involve a nervous system and neuro-immune response that has become stuck in a persistent “alarm” state. Your body is not failing — it is reacting.

New Leaf Neuro provides structured, science-informed education and practical guidance to help you recognize patterns, reduce physiological overwhelm, and build stability step by step.

Does This Sound Familiar?

✓ You’ve seen multiple doctors but still don’t have clear answers
✓ Symptoms shift and don’t follow predictable rules
✓ You react to foods, stress, temperature, or exertion
✓ You feel stuck managing flares instead of improving
✓ You’ve been told “everything looks normal”

You are not imagining this.
These patterns are commonly seen in neuro-immune and autonomic dysregulation.

-This is not just symptom management.
This is stabilization architecture.

Conditions We Commonly Support:

Common Issues w/ Dysregulated Nervous System Disorders

I'm Constantly Chasing Symptoms

I'm constantly chasing symptoms, visiting doctors who never have answers. My symptoms remain unexplained and often unrelated.

Countless Scans & Tests - No Answers

I have had so many scans and blood test that never seem to bring answers or clarity to my issues.

I Have Massive
Brain Fog

My brain fog, memory loss, and mental fatigue make daily tasks so overwhelming.

I Feel Hungover, Like My Body Is Poisoned

I feel hungover and sick, as if poisoned, despite not drinking any alcohol.

I End Up At The Emergency Room Too Often

Countless ER visits, no answers and no relief.

I've Been Diagnosed With (POTS) What Now?

I feel stuck, even slight movement sends my heart racing. Despite increasing salt and following a specialized exercise plan, my symptoms remain or worsen.

I'm Scared—Will This Ever Get Better?

I am getting no relief—will I always have to just manage symptoms?

I Have Developed Anxiety and/or Phobias

I have developed unexplained fears and anxiety I’ve never had before.

Everything Makes My Body React

My body reacts to everything—food, chemicals, EMFs, heat, and more—causing symptoms from anaphylaxis to asthma, hives, palpitations, and GI issues. What’s happening?

It's Not Just Stress

Yes, I have some stress but this is not just stress. I am tried of being prescribed anti-anxiety meds, and then being referred to a psychiatrist.

I Am Always
Exhausted

I am beyond tired, despite rest, with aching muscles and heaviness.

My Body Feels Overstimulated

Loud sounds, bright lights, crying on TV can trigger agitation and overstimulation.

From Reacting to Responding

During a flare, every decision can feel uncertain — rest or push through, add something or remove it, change diet or wait it out. Many people end up constantly adjusting without knowing which changes actually help.
We work with you to replace guesswork with structure. You learn how to read what your body is signaling and choose responses that support stabilization instead of adding more stress.
As patterns become clearer, symptoms feel less chaotic. Flares may still occur, but they are easier to navigate because you know what to do and why you are doing it. We provide practical, day-to-day guidance — the kind of decision-making support that often falls outside traditional medical visits.

Founder & Lead Consultant

Liz is a Health Educator and Environmental Health Scientist. As a Registered Sanitarian (RS) with training in cell and molecular biology, she translates complex biological and environmental concepts into clear, understandable education for individuals living with MCAS, POTS, and related conditions.

She leads the live New Leaf Neuro sessions, helping participants make sense of their experiences. Her work focuses on making complex physiology approachable so individuals feel more confident in navigating daily life while continuing care with their healthcare providers.

Liz also lives with MCAS and POTS, which informs the practical and supportive perspective she brings to her work.

Pascal Boudreau

Co-Founder & Program Director

Pascal is a Professional Engineer (P.Eng.) with a background in electrical engineering and systems analysis. He brings a structured, analytical perspective to the program, helping participants organize information and recognize patterns in their day-to-day experiences.

During live sessions, he helps guide discussion, answer questions, and support participants as they work through the material and apply it in practical ways. He also plays a key role in program development and organization, translating complex concepts into clear, manageable steps that can be implemented consistently over time.

Supporting Recovery Thru Education & Consulting

Our Approach

Many people with MCAS, POTS, and dysautonomia are left trying to manage daily symptoms without clear direction on what to prioritize. Our focus is helping you move from reacting to each flare toward a steadier, organized way of responding.

At New Leaf Neuro, we provide structured education and guidance so you can better understand how to approach symptoms, recognize patterns, and make practical decisions in day-to-day life. Rather than trying to figure everything out alone, you are given a clear framework and consistent support.

Ways to Work With Us

6-Week Online Live Stabilization Class

Most individuals begin here.

This weekly live class taught by Liz and Pascal includes teaching, guided discussion, and real-time Q&A. You may participate as much or as little as you are comfortable with — many people simply listen at first.

The class is designed to stand on its own and helps you organize what you are experiencing, identify patterns, and develop steadier responses in daily life.

Individual Consulting

Individual sessions are available for those who want more personalized guidance or are navigating more complex situations. Sessions can be done after the class, alongside it, or independently.

Your body is responding — not malfunctioning.

How Your Symptoms Connect

In conditions such as MCAS, POTS, dysautonomia, chronic anxiety, Long COVID, and other nervous system regulation conditions, symptoms may relate to changes in nervous system signaling. For many individuals, this is why learning ways to support steadier nervous system function becomes a very important focus.
When the nervous system remains persistently activated, it can influence how the body’s systems communicate — including immune responses, circulation, and other physiological processes.
