Disclosures:
I have received funding for two studies on
hyperbaric treatment in children with autism
from the International Hyperbarics Association
but I have no commercial or financial
relationships with chamber manufacturers.
With all treatments and recommendations,
please consult with your child’s physician
before implementation.
The use of every treatment in individuals
with autism is “off-label” except for
risperidone for the treatment of irritability
Autism Spectrum
ADHD
Asperger
Syndrome
PDD-NOS
Autism
Psychologically / Behaviorally defined
Communication
Stereotypical
behaviors
Social
interaction
Underlying pathophysiology ???
Autism: Pathophysiology
Cerebral hypoperfusion
Inflammation
– Cerebral
– Gastrointestinal
Dysbiosis
Mitochondrial dysfunction
Oxidative stress
Impaired glutathione production
Environmental toxicant exposures
Study Descriptive Terms
Prospective: planned ahead of time
Randomized: participants assigned to a
group by random allotment
Double-blind: Neither participants nor
researchers know group assignment
Placebo-controlled: A placebo is given
to one group of participants
Cross-over: placebo group crosses
over and gets treatment
Placebo Effect
As high as 30-37% in several studies in
children with autism
Points to need for double-blind,
placebo-controlled studies
However, also need to treat children
now, and cannot always wait for these
types of study
Need to evaluate the risk/benefit ratio
of each treatment
Evidence-based Medicine:
Strength of Evidence (Efficacy)
A: Supported by at least 2 prospective
randomized controlled trials (RCTs) or 1
systematic review
B: Supported by at least 1 prospective RCT or
2 nonrandomized controlled trials
C: Supported by at least 1 nonrandomized
controlled trial or 2 case series
D: Troublingly inconsistent or inconclusive
studies or studies reporting no improvements
Caveat
Double-blind, placebo-controlled studies
can cause you to lose sight of the
individual patient
– e.g., DMG: 2 negative double-blind placebocontrolled studies in autism (however, dose
in studies lower than we typically use). DMG
is ranked #17 by parents on ARI list. Some
children manifest good improvements with
DMG, including speech.
– e.g., Secretin
Caveat
Over 50% of what is done in medicine is “off-label”

Example of Study: A in Autism
Melatonin: 2 randomized, double-blind,
placebo-controlled studies
demonstrating improvement in the
amount of time to fall asleep, number of
nighttime awakenings, and length of
sleep compared to both baseline and to
placebo.

STEPS
Safety: has it been studied in children?
Tolerability: what are the side effects?
Efficacy: does it work?
Price: how much will it cost?
Simplicity: how easy is it to do?
STEPS: Melatonin
Safety: two double-blind studies
showing safety in children with autism
Tolerability: very little side effects
Efficacy: Double-blind studies showing
improvements compared to placebo
Price: less than $30 per month
Simplicity: pill taken at bedtime
DOEs versus POEMs
DOE: Disease Oriented Evidence
– Example: Cholesterol pill lowers my
cholesterol by 50 points
– Example: Flecainide
– Example: MB12 increases glutathione
POEM: Patient Oriented Evidence that
Matters
– Example: Cholesterol pill makes me live
longer, or prevents a heart attack or stroke
– Example: MB12 improves speech
Ideal Treatment
Backed by Strength of Evidence: A
Safe
Tolerable
Efficacious
Cheap
Simple, in-home treatment
POEM: Outcome matters to child/parent
Treatment Options: Know
Your Reason for Treatment
Based upon symptoms
– e.g., inattention: pycnogenol, zinc,
carnitine, iron, omega-3 fatty acids
Based upon laboratory testing
– e.g., oxidative stress: pycnogenol,
carnitine, CoQ10
Based upon probabilities
– e.g., most children with autism have low
glutathione: MB12, folinic acid, pycnogenol
