Dear blacknet:
This very interesting topic discusses hyperbaric oxygen for memory. It was my assumption that the author referred to memory loss in the elderly, as I mentioned above. I was taught by my instructor in hyperbaric oxygen therapy (Eric Kindwall), that the effect is primarily the result of personal contact and interaction, and it has less to do with the oxygen itself. The following are some references, all of them old.
[sp]· Goldfarb AI, Hochstadt NJ, Jacobson JH 2nd, Weinstein EA. (1972). Hyperbaric oxygen treatment of organic mental syndrome in aged persons. J Gerontol. ;27(2):212-7.
[sp]· Raskin A, Gershon S, Crook TH, Sathananthan G, Ferris S. (1978). The effects of hyperbaric and normobaric oxygen on cognitive impairment in the elderly. Arch Gen Psychiatry ;35(1):50-6
The use of oxygen for poisoning from carbon monoxide, hydrogen cyanide, or hydrogen sulfide is another matter. Here, oxygen under pressure has been shown to produce good results especially with regard to the late neuropsychiatric syndrome. This has been found in the United States and other parts of the world to be of benefit.
Some reports have also come out in favor of HBO for stoke victims. Apparently, it must be administered within an hour of ictus (= stroke). This was told to me a few years ago by Richard Neubauer, MD, of Florida. I have not heard anything recently, but at that time, he told me they we trying to get some form of HBO therapy on an EMS vehicle.
Therefore, HBO for senile dementia appears to not be successful, at least as currently applied. Other problems are more promising.
I hope that this helps.
