Consulting & Education for MCAS, POTS, & Dysautonomia

-Your partner in navigating the MCAS and POTS journey.

Welcome to New Leaf Neuro

With MCAS, POTS, Long COVID, and related conditions, symptoms often follow a pattern — a flare, some improvement, then another setback.

What is often overlooked is that these conditions commonly involve a nervous system that remains in a persistent “alarm” state. When the body stays on high alert, it affects many normal body functions — heart rate, digestion, breathing, circulation, and sensitivity to foods and environments. Because of this, symptoms can appear in many different parts of the body. This doesn’t mean the body is failing — it means the body is reacting to signals.

At New Leaf Neuro, we help you understand why your body signals change and what tends to trigger flares, providing you with the tools to support your body’s path toward balance and resilience.

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.

Our consulting focuses on the complex patterns often associated with neuro-immune and autonomic dysregulation.

-Because Education is the Key.

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.

Supporting Recovery Thru Education & Consulting

Our Approach

Many people with MCAS, POTS, and dysautonomia are left managing daily symptoms without clear direction.
We help you move from reacting to each flare to responding in a steadier, more organized way.
You don’t have to figure it out alone — we provide a clear framework and steady support.

To Programs

New Leaf Neuro provides educational and consultative services and does not offer medical care.

-You deserve clear explanations, not confusion or dismissal.

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.
