Dec. 13th, 2007 08:40 pmThe treatments available for Alzheimer's disease, from the NIH Institute on Aging.
I keep seeing people saying that it's good that Terry Pratchett was diagnosed early, because then there's more the doctors can do to help, and I'm getting very tired of it.
I suppose it is good that he was diagnosed before he, for instance, started having trouble driving and got into an accident because no one knew they should be watching him closely so they would know when to take away the keys. Or before he started getting lost easily. I suppose since he's early on and still healthy he's a better candidate for clinical trials (although given that the last clinical trials of an Alzheimer's vaccine that had been very promising in mice turned out to give humans meningitis, this is not necessarily a good thing).
But take a look at what the NIH has to say about actual treatments for Alzheimer's: they don't have any medications that slow the progression of the disease. People on drugs die just as quickly as they would have if they weren't on drugs. All the drugs do is improve the symptoms for a while. So if Terry were diagnosed a year from now, the doctors would do for him what they're probably doing now: put him on Aricept or Reminyl, or Namenda if he's progressed far enough, tell him to take gingko and vitamin E because they're good for the brain, and try to do crossword puzzles since mental exercise helps preserve brain function longer. That's it. And the only difference it would make to him is that his symptoms would have been somewhat less if he had started the medications earlier.
Unfortunately, Alzheimer's isn't cancer. You can't make a terminal case better with chemo or radiation to help slow the disease down for a while. So while catching it early is probably better than catching it later, it doesn't give you more options in treatment, or give you the option of more good years. The medications give you more good months, and while that is certainly something to treasure when someone you love is disappearing before your eyes, it's not much in the grand scheme of things. It's certainly not a reason to tell yourself that it won't be as bad because they caught it early.
