I take a lot of this stuff. It was the first PD pill I took, along with Elderpryl, so the CNN report this morning really grabbed my attention. The first time in ages that I saw something all the way through instead of catching the tail end of a report, like "....cure for Parkinson's. And in other news..." Somewhere in Germany (Bern?) there were a bunch of depressed horses (no, this is serious, really.) These horses stopped eating, some of them even killed themselves. I have no idea how a horse kills himself, but that's beside the point. When they did slides of the horse's brains they found a virus, now known as the Bern Virus (amazing how they come up with these names, isn't it?) Now researchers have found the same virus in the brains of humans who have killed themselves and find that Amantadine is effective in killing it (the virus, not the people.) Now isn't it interesting that a virus which installs itself in the brain, causing depression, can be attacked by Amantadine, a drug which, through some yet unknown method, also has a positive effect on PD symptoms? I certainly have a layman's' concept of the inner working of the brain, which is to say that I know enough to contradict where my wife thinks mine is located, but shouldn't this respark the theory that PD is caused by a yet unidentified virus?
