The current issue of Advanced Diver Magazine (#8) has an article by Bruce
Wienke and Tim O'Leary about tech diving medical concerns which opens with
references to studies that indicate associations between diving and
neurological symptoms, as well as other medical problems. The research was
done in the 1970's and 80's.

Subject: Re: brain damage and divers
Although a study like this would be very interesting, I doubt DAN would do
it, since there is no third party with an interest in funding it.
If results showed that diving mixes with helium prevented lesions seen in
other groups of air divers -- who would benefit financially? The only
group
I can think of are the people involved in the mining and distribution of
helium. I don't think they have a big stake or interest in the dive
industry.
Who would lose? Anyone teaching or promoting air diving (regardless of
depth). Potentially, recreational divers would be frightened by the risk,
but unwilling to pay for helium. This means less diving, less equipment
sales, less dive travel...
There has to be some other driver for doing the study, like pure research,
to
drive its occurrence.

Wendell, Trey,
as you both mentioned the basic problem is money to do a
scientificly sound study ("double blind").
On the other hand, in all the MRI centers round europe and
the states there should be a huge amount of stored previous
scans. If we could find a scientist who is willing to look
through them and sort them out, that may give some evidence.
Again the problem is money, as somebody has to pay the poor
guy. :-) DAN has probably done such studies, or may
be able to do further work on it.
I can not see big companies funding it, as there is no imidiate
profit in these studies. The so called
technical diving agencies like TDI or others, even PADI and
SSI should be interested in it (I am shure there are many others
I did not mention).
It is good to know that there are groups who are working on a
way to get this research done.
Jens.
