Autism, Asperger's, and other
Developmental and
Intellectual Disorders

There is considerable evidence linking gut issues such as dysbiosis in the small intestine to Autism and other neurological complaints. Dr. Weyrich has been trained in the use of the Great Plains Labs Organic Acid Test and other related tests for treating Autism and other neurological complaints.

For example:

• Yeast overgrowth in the GI tract is very commonly associated with autism, and symptoms often abate when the yeast infection is cleared.
• High body burdens of mercury are also often associated with autism, and symptoms often abate when the mercury burden is cleared.
• But it has also been observed that yeast overgrowth increases the absorption of mercury from the environment.
• Does that mean that yeast infection causes mercury toxicity?
• On the other hand, it has also been observed that it is harder to clear a yeast burden without first clearing a coexisting mercury burden.
• Does this mean that mercury toxicity causes yeast overgrowth?
• Or do we have a positive feedback cycle in which each reinforces the other?
• Just to muddy the water further, childhood vaccines have historically contained high levels of mercury (used as a preservative), and there are also reports suggesting that administering certain vaccines while a child has a yeast overgrowth is associated with the onset of autism.

Therefore with the caveat that association does not necessarily distinguish between cause and effect, the following factors have been associated with autism, in no particular order:

• High incidence of otitis media (ear infections) [Kontstantareas1987]. This may be associated with hearing impairment or to yeast dysbiosis secondary to antibiotic treatment [Shaw2008].
• Elevated urinary levels of 3-(3-hydroxyphenyl)-3-hydroxypropionic acid (HPHPA) and other markers of dysbiotic overgrowth with Clostridium spp. are common in autism [GP2008].
• Elevated urinary levels of arabinose, which may be problematic for children with a defect in their metabolism of pentose sugars. High levels of arabinose are found in certain fruits (apples and pears), but also arise from dysbiotic overgrowth of yeast [Shaw2008].
• Toxic metal exposure (mercury, lead, etc.) [Shaw2008].
• Gastrointestinal abnormalities observed by Andrew Wakefield (Royal Free Hospital, London) and Karoly Hovarth (University of Maryland School of Medicine) after vaccination with certain types of measles vaccine [Shaw2008].
• Genetic diseases of purine metabolism reported by Ted Page, Mary Coleman, et al [Shaw2008].
• MMR (Measles, Mumps, Rubella) vaccine. The British gastroenterologist Andrew Wakefield has associated lymphoid hyperplasia of the gastrointestinal tract leading to fecal impaction with the MMR vaccine [Shaw2008]. This research is controversial and was redacted by the British journal Lancet after claims were made of procedural irregularities and conflict of interest. More recently, data obtained from the CDC via the Freedom of Information Act has shown that at least one study conducted by the CDC showed a statistically significant correlation between Autism and the MMR vaccine. However, the CDC has released data from a smaller study showing no statistically significant effect.
• DPT (Diphtheria, Pertussis, Tetanus) vaccine [Bolte1998].
• Hepatitis B vaccine [Shaw2008].

• Dysbiosis (Organic Acid Test)

• Heavy metal toxicity.
• Gut dysbiosis.
• Genetic defect in purine metabolism [Shaw2008].
• Genetic defect in pentose sugar metabolism [Shaw2008].
• Vitamin B12 deficiency [Pacholok2011].

Arabinose

In some cases, it appears that a metabolic defect in the processing of pentose sugars such as arabinose may be the cause, since it is reported that in some children, eating fruits rich in arabinose (apples and pears) rapidly induces an exacerbation of autistic symptoms [Shaw2008].

It has also been hypothesized that arabinose, being an aldol (reducing) sugar which contains an aldehyde functional group, may contribute to pathology by reacting with the terminal ammonia group of the amino acid lysine, which is found in many proteins of the body, to form a pentosidine, which may further react with an arginine in an adjoining protein strand to form a pentosidine link [Shaw2008, pg 36], (Maillard reaction) The pentosidine link alters the structure and function of the affected proteins, which may be enzymes.

Dr. Weyrich notes that this is similar to the mechanisms underlying protein glycosylation, which is measured by the HbA1c test [Sell1989]. Both protein glycosylation and formation of pentosidine links are associated with aging - once these links are formed, they persist until the cell they are associated with dies and is replaced. Note that neurons are not replaced when they die. The concentration of pentosidines has been reported to increase linearly with age [Sell1989].

Elevated protein-bound arabinose has been found in the serum proteins of schizophrenics and in children with conduct disorders [Varma1983], [Varma1980]. Dr. Weyrich notes that it is not clear whether this is a marker for elevated arabinose, or a cause of the neurological pathology. In any case, accelerating the aging process is not a good thing.

Elevated urine arabinose has also been found in an autistic child in whom a brain MRI showed diffuse demyelization [Shaw2008].
