Is Oppositional Deifiance Actually Anxiety?

Oppositional defiance can cause a tremendous amount of suffering for both children and their families. I have long thought of it as another face of anxiety — one that too often leads to social isolation and rejection.
In this reel, I share research from the Walsh Research Institute showing that 85% of children diagnosed with oppositional defiance had a methylfolate imbalance (relatively high folate), which can contribute to lower serotonin activity. Undermethylation also appears to be a common root of anxiety and depression. Here I also discuss traits associated with undermethylation and related diagnoses.

The Gene That May Influence High Sensitivity (HSP)

CAPS (CYP21A2 Mutation Associated Neuropsychiatric Spectrum) described in Dr. Sharon Meglathery's RCCX Theory shares considerable overlap with the HSP (Highly Sensitive Person) concept developed by Dr. Elaine Aron. Both describe individuals with deeply sensitive nervous systems, high empathy, emotional depth, and a tendency to become easily overwhelmed by chaotic or high-stimulation environments.

RCCX Theory attempts to provide a biological framework underlying this psychological presentation. These traits appear to impact 20-30% of the population and are not considered pathologic.

As someone who has been "highly sensitive," I find RCCX theory to be very helpful in understanding not only vulnerabilities, but also strengths and how to harness those strengths effectively without burnout or overwhelm.

I'll be discussing CAPS, HSP and RCCX Theory in an upcoming newsletter.

Why Some Don't Easily Bounce Back Easily After Stress or Illness

Pyrrole disorder is a fairly common nutrient imbalance associated with a range of brain-related symptoms, including low stress tolerance and difficulty being in large groups or new situations. For some individuals, everyday stimuli can feel overwhelming—noises, bright lights, textures, and even people can feel like "too much."
In those who are genetically predisposed or who develop pyrrole-related imbalances, emotional or physiological stress can cause a relative depletion of zinc, vitamin B6, and magnesium. Zinc plays an important role in the central nervous system, immune system, gastrointestinal function, and connective tissue, including the skin and joints. Vitamin B6 is required for the synthesis of several neurotransmitters.
In this reel, I discuss how this nutrient imbalances may contribute to difficulties with resilience and "bouncing back" after a stressor or illness.

Is EMF Sensitivity Real?

When it comes to EMF sensitivity, most people’s not familiar with think of the series, “Better Call Saul.,” The main character’s older brother, Chuck, has electromagnetic hypersensitivity - portrayed as being largely psychosomatic.

In 2015 Igor Yakymenko and collegues looked at 100 studies on the impacts of EMF on living organisms and found that 93 confirmed that RFR induces oxidative effects in biological systems. Oxidative stress in humans results in a depletion of protective antioxidants and thus damage to DNA and cells.

In this reel, I discuss my expereience treating people who have EMF sensitivty, most of which had no awareness of EMF or reported impacts when their symptoms began shortly after a significant increase in EMF exposure. I also discuss the three parts of treatment, including addressing the underlying root cause.

What May Be at the Root of Health Anxiety?

What Toxin May Be Driving Chronic Fatigue? (Research Data)
Chronic Fatigue Syndrome, now more commonly referred to as Myalgic Encephalomyelitis (ME/CFS), is a debilitating physical illnesss. Many people who struggle with this condition often don’t “look sick.”

Core symptoms include:

• Post-Exertional Malaise (PEM): Even minor physical or mental exertion can trigger a severe and prolonged worsening of symptoms.

• Unrefreshing Sleep: Patients often wake up feeling just as exhausted as when they went to sleep.

• Cognitive Impairment: Commonly referred to as “brain fog,” causing difficulty with memory, concentration, and clear thinking.

• Orthostatic Intolerance: Dizziness or lightheadedness that worsens when moving from sitting or lying down to standing.

• Additional Symptoms: Muscle and joint pain, headaches, flu-like symptoms, and more.

In this reel, I discuss common root causes I frequently see in my practice that are also supported by research conducted by Dr. Joseph Brewer, an infectious disease specialist.

(My own healing from CFS/ME came about by addressing this toxin along with mast cell activation).

What Finger Length Ratio May Reveal About the Brain

A male-pattern finger length ratio (the ring finger is longer than the index finger) in women has been associated with an increased risk of anxiety, as well as higher self-reported competitiveness, assertiveness, and a greater propensity for risk-taking. There also appears to be a higher incidence of giftedness and neurodivergence among women with this trait. Economists studying founders and business leaders have found that some of the most successful female entrepreneurs and executives often had ring fingers 10–20% longer than their index fingers.
In this reel, I discuss how finger length ratio may relate to various brain-related traits and symptoms.
(Though not discussed in this reel and fitting with RCCX theory, this relationship may be due to a genetic variant affecting 21-hydroxylase, an enzyme involved in hormonal pathways.)

Depression: Not One Size Fits All - The 5 Biotypes

Psychiatric research often starts with the assumption that, for a given condition, there is one cause and therefore one treatment. Researchers may study the effects of a single medication on 1,000 people with depression. Even if some respond well, if enough people do not respond, the treatment may be deemed a failure.

This clinical trial design is largely shaped by regulatory agencies and the pharmaceutical industry, both of which rely on the Diagnostic and Statistical Manual of Mental Disorders (DSM). However, DSM diagnoses do not account for the different biotypes underlying these conditions.

In this reel, I discuss the five biotypes (biochemical imbalances) of depression identified by the Walsh Research Institute, each with its own distinct traits, lab findings, and treatment.

Could Mold Toxicity Be the Hidden Reason Students Leave College?

Though I’ve been treating mold toxicity for the last 9 years, I’m still surprised by how common it is among people experiencing brain-related symptoms such as depression, anxiety, brain fog, fatigue, mood swings, and at times, even psychosis.

I often see students who have had to leave college because of new-onset symptoms that appear to be largely related to mold toxicity acquired in their dorm or off-campus apartment. Once properly diagnosed — often with the help of urine mycotoxin testing — and treated (which can take time), most are able to return to their educational path.

Sadly, many students leave college never realizing they have mold toxicity, and instead come to believe that their loss of energy, motivation, and focus simply means that “college isn’t for them.”

The Art of Saying 'No" For Better Health & Relationships

We're allotted only so much time, energy, and attention in this life. When we say "yes" to requests we really want to say "no" to, we're also saying "no" to the things that truly deserve those scarce resources.
Resentment builds, our health and relationships suffer, and we forget what we're actually here for."
