Dr. Curtis Dohan dedicated much of his professional life to exploring and
publishing the connection between cd and schizophrenia. I believe he is
an unsung medical hero of the Twentieth Century. The future will herald
his achievements, as he took one of the first major steps toward the
understanding some of the biochemical processes at work in many mental
illnesses.

Dohan learned about a comparatively high frequency of schizophrenia
in celiac disease, in discussion with a gastroenterologist. He had
previously been aware of several celiacs among his schizophrenic patients.
In 1966, Dohan published a report that schizophrenics improved on the
diet used for treatment of celiacs (1)

Dohan and Grassberger, as staff psychiatrists, began double blind trial of a
gluten-free, casein-free diet in a locked ward for mental patients. In their
published report, this group stated: "These clinical studies support the
hypothesis that cereals play a role in the pathogenesis of overt symptoms
in those with an hereditary capacity to develop schizophrenia"(2)

A small flurry of research activity followed when this study was supported
by Singh and Kay, who had also studied a population on a locked ward,
with a similar result (3). The studies that followed provided conflicting
information. Where adequate time is allowed, and the diet is strictly
observed, improvement occurs. Studies of less than six months' duration,
or where the diet is not strictly observed, there are few or no
remarkable improvements.

A lesser man might have allowed his insight to wither under the burden of
scepticism. Dohan continued his work by searching for confirmation of his
hypothesis. Zioudrou et. al. provided support, by discovering
endorphin-like peptides (exorphins) in enzymatic digests of glutens (4).
Mycroft et.al. discovered that gluten contains a neuropeptide which
enhances dopamine activity (5).

Dohan et. al. published a report demonstrating that schizophrenia is
virtually non-existent in cultures where glutinous grains are not
consumed (6).

Marginalized, and often ridiculed, Dr. Dohan continued to express his
ideas, and had his work published in many professional journals. What was
the problem? Why was his work less recognized? His work as a researcher
withstood the scrutiny of his peers repeatedly, throughout his life.

It is my opinion that Dohan's work threatened much of the social and
economic structure surrounding agriculture and the food industry,
that his ideas were unthinkable to the readers of these journals. In other
words, it was a challenge to the dominant paradigm, so it was dismissed
without serious consideration, except among a tiny group.

This tiny, geographically fractioned group has learned to apply this
concept to a variety of mental illnesses. Doctor Reichelt in Norway works
primarily in the field of autism research, as does Dr. Shattock in Great
Britain. In the US, an underground network of concerned parents has
emerged on the internet. But the work is scattered, and without funding.
(I am currently exploring some connections between gluten and attention
deficits, and learning disabilities.)

Dr. Curtis Dohan, of Philadelphia, Pa, pioneered opioid research in
mental illness, and has blazed a trail for future generations. He is a
genuine hero of Twentieth Century medical scientific inquiry. Our
education system is such that we foster this, and similar dynamics of
denial within the scientific community. We need to revamp our education
system, from elementary to medical school, in the realm of science
instruction, in the interest of the survival of human culture. We have
not advanced very far from the incarceration  (house arrest) of Galileo
for suggesting that the earth was not the center of the universe.

I hope this is helpful.
Best Wishes,
Ron Hoggan

Hi Don and list,

You said:

"I don't think anything much is gained by hypothesizing grand
conspiracies."

I'm sorry if what I said sounded like a conspiracy theory. It was
intended as a critical comment on the methodologies employed in teaching
science, and the unthinkable nature of the implications of Dr. Dohan's
hypothesis.

You say you are unconvinced by his work. Perhaps the work of Abrams and
Hoffer, in the treatment of schizophrenia with megadoses of nicotinic
acid was what convinced me. Their experience treating thousands of
schizophrenics showed results that would be totally consistent with
Dohan's hypothesis. If the patient was not yet chronic, (absorption
capacity for this vitamin was not yet totally destroyed) remissions could
be achieved through megadoses, and the megadoses had to be continued for
life, and had to be adjusted to variations in tolerance. I could go on,
but what I think is important here is that these folks were working in my
backyard (so to speak) and I know that the results they were getting were
very real. I know some of their former patients.

There are other, similar triangulations, from the literature, that convince
me.

I am also convinced that Dohan's work has some profound implications for
cancer research.
Sincerely,
Ron Hoggan

They were conducted on locked wards. Control was quite meticulous.

The regions he looked at were:
remote regions of Papua, New Guinea (1950-1967) and Malaita, Solomon
Islands (1980-1981) and on Yap, Micronesia (1947-1948)

I would welcome his further input on this topic, and I'm confident that
there are others on the list who would like to hear his assessment.

Best Wishes,
Ron Hoggan
