Consulting & Education for MCAS, POTS, & Dysautonomia
-Your symptoms aren’t random. We help you understand what they mean and how to respond.
Welcome to New Leaf Neuro
People living with MCAS, POTS, Long COVID, and related conditions often notice a repeating cycle — a flare, some improvement, then another setback. These conditions frequently involve a nervous and neuro-immune system that remains in a persistent “alarm” state. When the body stays on high alert, normal functions such as heart rate, digestion, circulation, breathing, and food tolerance can shift from day to day.
Because of this, symptoms appear inconsistent — yet they often follow patterns. What is often missed is that different flare states can feel similar while requiring different responses. Without understanding which pattern is occurring, people understandably rely on trial-and-error, and the wrong response can unintentionally prolong the flare.
At New Leaf Neuro, we first teach stabilizing practices that help lower overall reactivity. We then help you recognize flare patterns, understand why your body’s signals change, and respond more consistently so you can move through flares and gradually establish that steadier baseline in time.
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.
Your symptoms may look the same from day to day, but the underlying pattern can be different.
We help you identify the pattern so you know what to do next.
-Helping you understand your body’s signals so you can respond with confidence, not guesswork
Conditions We Commonly Support:
Common Symptoms in the MCAS, POTS & Dysautonomia Community
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.
How New Leaf Can Help
New Leaf Neuro provides structured education and practical guidance for individuals living with MCAS, POTS, and dysautonomia.
We help you move from reactive experimentation to clear pattern recognition and consistent response.
We teach you how to:
• Identify what type of flare you are in
• Respond appropriately without over-correcting
• Use food and daily routines to create stability
• Build response habits that reduce constant symptom monitoring
Our goal is not to diagnose or treat disease.
Our goal is to help you understand what is happening and know what to do when it happens.
-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 .

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.
-
When the nervous system stays “on,” it can affect immune activity, circulation, and other body functions.
