• Biomedical view of autism: Autism is a
disease resulting from underlying,biological abnormalities (pathologies).
• Behavior analytic view of autism: Autism
is a neurological disorder resulting inbehavioral excesses and deficits (Lovaas,2003).

underlying biological basis of autism, but no

biomedical treatments for autism, each based
on a different theory about the underlying cause

• Excess Yeast in the intestinal tract.
– Low good bacteria allows yeast to proliferate– Antibiotics may stimulate yeast
– Yeast colonies attach to the intestinal walls and digest portions of
– Undigested food molecules can then “leak” through the intestinal
– Result: Increased susceptibility to allergies resulting in behavioral
• Elevated peptides in urine resulting from incomplete
breakdown of gluten (in wheat) and Casein (in dairy).
• Theory: Incomplete breakdown of gluten and casein in the
gut results in excess caseomorphines, gluteomorphines and
gliadinmorphines which are opioid like peptides.
– These opioids have abnormal leakage from the gut.
• These cross the blood-brain barrier and affect the CNS and inhibit
– These opioid peptides modulate monoamine transmitter systems.
• Unusual effects on transmitter systems may explain a variety of the
behavioral traits in autism (E.g. attention and social indifference).
• What is a Gluten-free, Casein-free (GFCF)
– Elimination of all gluten containing foods
– Elimination of all casein containing foods.
– 3 children who received secretin for gastrointestinal
problems showed significant behavioral improvementsin social and language skills.

– Function: to cause the pancreas to release bicarbonate
• Bicarbonate neutralizes stomach acid so that enzymes can
– An infusion containing either human or porcine secretin
• Children with autism do not produce enough secretin thus
impairing their digestive processes.
– Reduced secretin production may be related to gluten
• Children with autism produce a defective type of secretin that
is not capable of stimulating the pancreas.
• Secretin has some direct beneficial effect on brain functioning
• The autoantibodies against the pancreas, induced by Candida,
may be preventing the pancreas from responding to the normal
amount of secretin produced by the child’s own body.
• Abdominal cramps, bloating, diarrhea,• GI tract bleeding• Fatigue, fever, flushing• Decreased blood pressure• Bradycardia (Slow heart rate)• Excessive sweating• Nausea, hot sensation, headaches• Vomiting• Numbness• Possible seizures• Transient respiratory disease.
– The regressive form of autism represents a form of mercury poisoning. – Symptoms of autism are similar to the symptoms of mercury poisoning. It is
believed that the cause of this may be exposure to mercury in thimerosol, the
• (a) symptom onset shortly after immunization• (b) ASD prevalence increases corresponding to vaccination increases• (c) similar sex ratios of affected individuals• (d) a high heritability rate for autism paralleling a genetic predisposition to Hg sensitivity

• Courtney will discuss this issue in detail next week. • We will focus on Chelation as a treatment for heavy metal toxicity.
– Testing: Hair analysis- heavy metals such as mercury
may be 250 times higher in the hair than in the blood.
• Removal of any source of heavy metal poisoning• Use of agents to remove toxic metals• Chelation agents bind to toxic metals in the blood or tissues
and the metal-chelation agent complexes are eliminated in theurine or the stool.
• Prescription drugs: BAL, DMPS, EDTA, DMSA. DSMA is

• Theory: Children with autism have a metabolic disorder.
– The breakdown and metabolism of food into acids and sugars is
disrupted by abnormal chemical reactions.
– This results in too much or too little of certain vitamins and
– These deficiencies or excesses of certain vitamins and minerals
effects body and brain functioning, resulting in the symptoms ofautism.
– If these deficiencies or excesses are remedied, or if the metabolic
disorder is addressed, the symptoms of autism will decrease or beeliminated.
• B6 and Magnesium – High dose pyioxine
(B6) is administered often in combinationwith magnesium.
• Folic Acid – Administered as a supplement. • Calcium – Administered as a supplement.
• Inclusion criteria: Random assignment and controlled (placebo
– Two studies met criteria for inclusion. – One study (Tolbert, 1993) could not be evaluated due to lack of
information and inability of the author to provide thatinformation when contacted.
– The other study (Findling, 1997) showed no significant
differences between the control group and treatment group insocial interaction, hyperactivity, impulsivity, communication orcompulsivity.
– B-Cells: Produce antibodies (immunoglobins). – T-Cells: Kill foreign or infected tissues and produce large proteins
that regulate the immune system and enhance immune response.
• Theory: Children with autism have abnomalities or
deficiencies in T-cells, B-cells or related phagocytic cellsand proteins.
– Due to these abnormalities or deficiencies, their immune response
– They may be more susceptible to allergies, gut issues, and excess
• Types of immunotherapy treatments (most common):
– Transfer Factor: low molecular weight dialyzable molecule– Pentoxifyline: phosphodiesterase inhibitor known to have
immunomodulatory, hemorrheologic and serotonergic effects.
– Intravenous Immune Globulin (IVIG): prepared from plasma from

– Results of the non controlled studies that have been carried out
show mixed results (3 found support, 4 found negative results).
• Antipsychotic• The only drug approved by the FDA for the
treatment of “irritability” in autism.
– Irritability: aggression, deliberate self-injury
• FDA approval based on two, 8-week placebo
– Significantly more improvement in irritability scores
from baseline compared to the placebo group.
– Reductions in scores on the parent-rated Aberrant
– Significantly greater improvement in stereotypic
behavior, lethargy, social withdrawal, hyperactivityand/or noncompliance subscales for the treatmentgroup.
