blonde hair and blue eyes among ADHD

[ross]

In the following web site:
http://www.chiro.cc/health_info/add.htm
Canadian Dr. Zoltan P. Rona from Toronto wrote:
"ADD affects more boys than girls with a ratio of 3:1. A high
percentage of hyperactive children have blond hair and blue eyes and
suffer from what appear to be allergic signs and symptoms."
Later on he added, "In the more severe cases they may be "rockers" or
"head bangers" rejecting affection and mothering."

Is he saying children with blonde hair and blue eyes have more chance
of getting ADHD? Can someone please clarify the sentence, "A high
percentage of hyperactive children have blond hair and blue eyes and
suffer from what appear to be allergic signs and symptoms."

Since I never heard that there was any such study done that showed
that most ADHD children have blonde hair and blue eyes, can someone
please provide a link or reference for any such study? Was there any
study done that showed that blonde and blue eye children have high
percentage of ADHD?

Also, what is the percent of ADHD children having blonde hair blue
eyes vs brown hair and brown eyes? (for example earlier he indicated
that there was a 3:1 chance of boys having ADD than girls)
Thanks.

This would be indicative of Autism Spectrum Disorders rather than simply
ADHD.

We need to look at the percentage of blonde, blue-eyed childred with
allergies in the general population to know if this really is indicative of
a prevalence difference.

Take a close look at the number of participants he bases his theories upon.
If these are large then he may have a theory that could be put to a
statistical scientific test. It may be that in his particular practice, he
is located in an area where there are general population genetic trends that
are simply reflected in the patients he sees.
