The
results showed that ADHD ratings are high in children
with dyslexia and that children with both the inattention
and hyperactivity/impulsivity forms of ADHD displayed
signs of fatty acid deficiency. After twelve weeks, the
group receiving the LCP supplement displayed significant
improvements in the average scores for cognitive problems,
behavior problems and anxiety, as measured on the Conners'
Parent Rating Scales. The children receiving the placebo
showed no improvement.
When
the placebo group was switched to LCPs they too displayed
significant improvements while the other children, who
continued to use LCPs, maintained their reduction of
symptoms.
This
is the most compelling research to date. As a doubleblind
trial in which neither the doctors nor the participants
knew who was getting the real thing and who was getting
the placebo, it is particularly valid.
Dr.
Richardson and her team have also conducted two other
trials with a total of some 200 participants concentrating
on LCP supplementation and dyslexia. One study consisted
of one hundred adultssome have dyslexia; others
do not. The second study comprised a similarly large
group of childrenall with dyslexia. The results
of supplementation have not been made available but an
analysis of baseline data showed that in the dyslexic
adults there were greater signs of LCP deficiency compared
with the nondyslexics. In the dyslexic children,
those who were more deficient in LCPs were more behind
in their ability to readsome by as much as thirty
months.
Earlier
research with dyslexics and dyspraxics was pioneered
by B. Jacqueline Stordy,PhD. of the University of Surrey
in the UK.
Initially,
Dr. Stordy discovered that mothers of dyslexic children
had, while pregnant, been on a diet low in omega3
fatty acids compared to the mothers of nondyslexics.
She then found that a group of young adult dyslectics
had poor night vision and were probably deficient in
DHA. When dyslexics were given 480 milligrams of DHA
a day as fish oilfor just a monththeir ability
to see in the dark bcame equally as good as that of nondyslexics.
In
a study with dyspraxic children aged between five and
twelve, Dr. Stordy found motor skillsmeasured using
the ABC Movement Assessment Battery for Childrensignificantly
improved following four months of LCP supplementation.
Behavioras measured using the Conners' Parent Rating
Scalesalso improved and the children were significantly
less anxious.
Research
at Purdue University has shown that boys with ADHD had
clinical signs of LCP deficiency and displayed greater
behavioral problems. A study supplementing a group of
ADHD boys with a high DHA fish oil supplement showed
improvement in behaviorbut not across all measures.
It was noted, however, that the less LCP there was in
a child's blood, the worse the child's behavior.
