Chronic Yeast Toxicity and Autism

Posted on 06 September 2011 by admin

The organic acid test is essential to analyze for yeast, and bacterial overgrowth. It is also helpful to assess the level of oxalate excretion, and other factors related to glutathione and antioxidant status, serotonin metabolism, quinolinic acid production (a marker for potential brain toxicity) as well as markers for in-born errors of metabolism including oxalate and amino acid dysfunction.

Case History Yeast and Pervasive Developmental Disorder (PDD-NOS)

Mark was one of my first ASD cases back in 1998. He was a 2 year old boy diagnosed with PPD-NOS (not otherwise specified). His development was typical of the history listed above. Multiple ear infections had led to repeated antibiotics for months on end. Loose stools were the norm as he struggled to maintain eye contact and learn in school. I ordered an Organic Acid Test (OAT) from Great Plains laboratory and discovered a massive amount of yeast metabolites – arabinose being the most common and quite elevated in Mark. Being new to biomedicine for autism all I knew (back in 1998) to do was make a recommendation for a gluten/casein-free diet and antifungal therapy. The anti-fungal medication was called Nystatin. Mark’s mother also implemented some basic supplements including a multi-vitamin and mineral, probiotics, and digestive enzymes.

After 18 months of continuous use of Nystatin, dietary modification and general nutritional support Mark was mainstreamed into regular school and continued to do well. His repeat OAT finally showed no yeast overgrowth. This case illustrated for me the powerful changes that could happen for an ASD child with basic dietary intervention and prolonged antifungal therapy.

Yeast has a tremendous effect on health. What are common in children with yeast overgrowth are behaviors that suggest dissociation, withdrawal, and aloofness. The most common behaviors that I see most commonly attributable to a yeast overgrowth problem are the following:

Poor eye contact.
Increased self-stimulatory behavior – fixating on spinning objects, odd hand movements including and finger-flicking in front of eyes.
Becoming withdrawn.
“Silly, goofy and/or giddy” – but this is not a behavior that involves other people. The child becomes silly, goofy and/or giddy to themselves. Parents will often describe that their child appears drunk.
Increased sugar craving.
Overall increased sensory seeking behavior, i.e. pressure

Other parents can describe more subtle differences, but those listed above are fairly common manifestations. What is most prevalent with “yeasty” behavior is a giddiness that mimics drugged or drunk behavior. When they are put on medications such as Nystatin or natural remedies, i.e. oregano oil, and/or grapefruit seed extract these behaviors improve.
