Alzheimer's disease, the leading cause of dementia, has long been assumed to originate in the brain but new research indicates that it could be triggered by breakdowns elsewhere in the body.
The findings, published today in Molecular Psychiatry [DOI: 10.1038/mp.2017.204] [DX], offer hope that future drug therapies might be able to stop or slow the disease without acting directly on the brain, which is a complex, sensitive and often hard-to-reach target. Instead, such drugs could target the kidney or liver, ridding the blood of a toxic protein [amyloid-β protein] before it ever reaches the brain.
"Alzheimer's disease is clearly a disease of the brain, but our research shows that we need to pay attention to the whole body to understand where it comes from, and how to stop it," said Dr. Weihong Song, UBC psychiatry professor.

Would a drug that targets amyloid-β in the body be helpful in preventing the onset of Alzheimer's? Could the potential onset even be detected by screening for amyloid-β which TFA says is a precursor? The presence of amyloid-β and other factors could indicate to treat with drugs targeting amyloid-β. (Not mentioned is how many drugs treat this.)
Millions of people could benefit from such treatment if it enabled politicians to remember what they said, promised or tweeted just yesterday. It might also be helpful for press secretaries and even people running for office.
When trying to solve a problem don't ask who suffers from the problem, ask who profits from the problem.

How many hundreds of billions (trillions) of $ will be spent on targeting a-beta before this is over? No data or reasoning seems to put a dent in the enthusiasm for this idea.

To whoever downvoted, can you find one disease state where someone has looked for a link to amyloids and not found it? Amyloids are like the generic cold symptoms of diseases because it requires constant vigilance to prevent their formation (they are the lowest energy state for any peptide).

Which would be: No one. The only moderation that post got up to now is a single Disagree, which doesn't reduce the post's score, therefore is not a downvote.

I am currently watching my grandmother go through the stages of Alzheimer's disease as my wife and I caretake for her. After watching this I want to make sure that I am able to kill myself if I ever develop the kind of mental deterioration that comes with this (and other) diseases. As part of this a friend of mine and I have been discussing checks that you can make against your brain to confirm your mental ability and then commit these to habit. The goal is to be able to run your own system diagnostics through a series of thought processes to determine you are at a point where you need to take action without returning false positives.
Being people of intellect I imagine that this is something other soylentels have thought about to. Any ideas?
Something that I do daily is run through the multiplication tables in my head. Pretty easy, but could be a useful method in this case.

An OS watchdog timer only works if the kernel itself hasn't become corrupted; I don't think it's possible for system to analyze itself effectively without a rogue component that has been designed to be as independent as possible from the rest of the system.
I mean, there's a reason it's difficult for a lot of people to keep themselves from drinking too much alcohol; it's hard to be reasonable about something that explicitly diminishes reason.
Instead of figuring out how to self-check, spend your time figuring out how to kill yourself in a non-violent, peaceful way, which includes figuring out how to prepare yourself to follow through with such a decision. Alzheimer's or not, the longer you live, the more likely you'll need to make that choice (or, like most people, choose not to think about it, and then just futilely claw in fear as the Universe sucks you down its merciless hole of eternal oblivion). Hypoxia by nitrogen gas seems like a good choice.
None of us knows how the story will go. The only thing we do know is that it won't end well. Prepare accordingly.

Music Therapy. Insist that, should your mental condition deteriorate, your family and/or caretakers regularly play music and other media from back when you were younger and stronger.
So for current old Geezers, this would be stuff like Louis Armstrong, Gershwin, perhaps some fifties and even sixties shit. Old TV shows etc. The sense of association can tie who they were to who they are today.
Note: I didn't come up with this idea, but I think it's a good one -- who likes the crap media churned out nowadays anyway?
The second I become incontinent or demented, I'm going to go full-chimp and fling my poo at people while making monkey-noises. That's always been my lifelong dream, just gotta wait until I have the right excuse to do it.

You've been channeling my father's ghost. He got Alzheimer's and towards the end one of his joys was to take his urine bag and swing it around his head...at some point it usually broke.

Once you get past your peak your general trajectory is deterioration for most stuff, BUT you can still enjoy life. And as long as you're having a decent quality of life and not being a big burden or problem for others why kill yourself? Just because you're starting to forget stuff or start not being able to do some stuff?
Most pet dogs don't think that well but lots of people still love them AND want them to still be around. Even the really stupid ones.
Similarly lots of us don't mind those kind gentle old folks with good hearts even if they're forgetful. Then it's only near the very end that it becomes a big problem, but that's true for the many other ways you can age to death (cancer, heart problems etc).
So maybe what might help is training yourself and your character so that even if you're a forgetful person you'd still be a nice forgetful person that normal people are happy to be with. There are some paranoid and angry forgetful people who accuse other people of stealing stuff, get angry and make a huge fuss for small stuff, etc.
Unfortunately there are cases of nice people being changed by Alzheimer's to becoming nasty people, not everyone though.

That wouldn't be the first time that has happened in the field of medicine.
There are more than a few very common diseases where diagnosis is just wrong. [cnn.com]
Yet these guys write that is if recognizing the misdiagnosis is somehow a bad thing.
Behavioral based diagnosis is a tricky business at best. Deciding that Neurodegeneration is in progress really says nothing about the source. If AD is defined as the presence of Aβ accumulation, AND Aβ accumulation is missing, then what would be the point of continuing to treat Aβ accumulation?
No, you are mistaken. I've always had this sig.

I doubt it'll work for everybody (lots of other causes for dementia) but it may work for lot of people. After all many people have type 2 diabetes, so while not all dementia might be "type 3 diabetes" a large percentage might be:

Based on the above research - I think these 'new treatments' will prove to be ineffective.

how about screw you? why don't you skanks just educate people on their lifelong habits(bad nutrition, etc) and pollutants that are causing the shit and we won't need your expensive, likely poisonous drugs. oh, actually fixing the problem isn't absurdly profitable? i wonder if selling doctors and drug chemists' forcibly harvested organs is profitable...
