Common Symptoms
I'm constantly chasing symptoms, visiting doctors who never have answers. My symptoms remain unexplained and testing never seems to bring answers.
I'm Constantly Chasing Symptoms, Scans & Testing
Countless ER visits, no answers. My body reacts to everything—food, chemicals, EMFs, heat & more— anaphylaxis to asthma, hives, palpitations, and GI issues and more. What’s happening?
I'm At The Emergency Room Often & React to Everything
After Mold Exposure I Now React to Everything.
After my house had mold, I am reacting to everything—cleaners, perfumes, and scents. Will I ever be able to live like I did before?
I Have Massive
Brain Fog
My brain fog, memory loss, and mental fatigue make daily tasks so overwhelming.
I'm Scared—Will This Ever Get Better?
I am getting no relief—will I always have to just manage symptoms?
I Am Always
Exhausted
I am beyond tired, despite rest, with aching muscles and heaviness.
I Feel Hungover, Like My Body Is Poisoned
I feel hungover and sick, as if poisoned, despite not drinking any alcohol.
I Have Developed Anxiety and/or Phobias & It's not Just Stress
I have developed unexplained fears and anxiety I’ve never had before. It's not just stress. I am tried of being prescribed anti-anxiety meds, and then being referred to a psychiatrist.
My Body Feels Overstimulated
Loud sounds, bright lights, crying on TV can trigger agitation and overstimulation.
Does This Sound Familiar?
✓ You’ve seen multiple doctors but still don’t have clear answers
✓ You react to foods, stress, temperature, or exertion
✓ You notice symptoms flare in certain rooms, homes, or workplaces
✓ You react strongly to everyday products like cleaning supplies, fragrances, or new materials
✓ You feel stuck managing flares instead of improving
✓ You’ve been told “everything looks normal”
What Is Causing My Symptoms?
Did you know your symptoms are actually being driven by a different mechanism than the original trigger?
-
So here is what happened, your body experienced a trigger, maybe it was environmental - (like mold, poor air quality, or VOCs) or maybe it was internal (such as a viral illness, stress, or injury). This trigger shifted the nervous system into a reactive, protective state. Normally this self-corrects, but sometimes it gets “stuck on.” When it stays "stuck on" we call this nervous system dysregulation.
-
Here is the surprising part, even after the trigger has been removed, the system can remain activated and continue driving symptoms. This is why treating these conditions through conventional medicine can be tricky and not always well understood. It’s also why it’s important to address, not just the trigger, but the mechanism that was switched on so it can stabilize and move back toward regulation.
-You deserve clear explanations, not confusion or dismissal.
Meet the Founders
Liz McGhee
Co-Founder | Environmental & Neuro-Immune Autonomic Consultant
Liz McGhee, RS is an Environmental Health Scientist and Registered Sanitarian with training in cell and molecular biology and communicable and infectious disease. Her work focuses on the relationship between environmental exposures, immune signaling, and autonomic nervous system regulation.
Through New Leaf Neuro, Liz helps individuals interpret environmental factors such as mold, indoor air quality, and chemical exposures alongside symptom patterns seen in conditions including MCAS, CIRS, POTS, MCS, ME/CFS, Long COVID, and other neuro-immune and autonomic conditions.
Her approach emphasizes identifying patterns across environment, physiology, and lived experience to help individuals better understand environmental triggers and move toward greater stability & regulation.
Pascal Boudreau
Co-Founder | Principal Building Systems Engineer, P.Eng
Pascal Boudreau, P.Eng. is a licensed Professional Engineer with over 30 years of experience in systems analysis and engineering design, including work in complex infrastructure systems such as power systems and telecommunications.
At New Leaf Neuro, he applies this systems-based perspective to the built environment, focusing on how moisture dynamics, ventilation patterns, and indoor air quality influence environmental safety.
Pascal helps interpret how building conditions may affect symptom patterns for sensitive individuals and leads New Leaf Neuro’s Environmental Building Masterclasses on creating healthier indoor environments.
-Your body is not failing.
These symptoms often represent a protective system that has become overly reactive. When you understand the patterns and respond consistently, the system can settle .
