New Blood Test Offers Early Warning for Alzheimer's Onset
Georgetown researcher (and executive dean of Georgetown's medical school) Howard Federoff has taken a "systems" approach to diagnostics for certain chronic diseases. By comparing blood samples taken from patients who subsequently developed Alzheimer's to blood samples after the disease has manifested, Federoff has identified markers and created a blood test that is described as "90 percent accurate" (the BBC article does not delve into the ratio of false positives to false negatives) in predicting whether a currently healthy patient is likely to develop Alzheimer's in the following three years. Understandably, this raises some ethical and practical questions. What would you do differently if this test came back positive for yourself? Or for a parent? Here's the (paywalled) paper, at Nature Medicine.
The main symptom that brings people to the neurologist is forgetfulness. Most of the time it's subjective (ie. I know someone with Alzheimer's and I begin to notice and worry about the times I meet people and the names won't come to my head). We look for signs of cognitive impairment, with tests that include memory and other mind processes. Of course, YMMV depending on your previous performance, career, educational level, etc.
Once we get proof of MCI, we can make some tests because Alzheimer's isn't the only thing that can cause it. The usual stuff ranges from depression or unfelt strokes to syphillis. The CAT scan/MRI only tells us if the brain is intact, somewhat like trying to work out if a car works by just opening the hood.
Alzheimer's itself can only be diagnosed under the microscope right now. Not a thing we'd agree to to do a live brain.
Other than this blood test, there are radioactive tracer tests and CSF tests. In all of them the result is a chance or ratio telling the possibility of the MCI to be a sign of Alzheimer's against something else.
So, it's a disease for which there is no prevention nor a cure and the current tests just tell us "yes your worries about that time you left the keys on the toilet are related to a 75% propability of having Alzheimer's". We should get into positive and negative predictive values here.
As I tell my patients: "No: there is no sign of cognitive impairment right now. If I knew you were to develop a demence, I'd suggest you settle your pending issues right away, but I don't see a reason not to do that, anyway, You don't know what awaits you at the turn of the corner."
Is if you forget to go to your appointment to take this blood test.
If the test is 90% accurate and then has 10% false positives, then one out of ten people who fail the test is actually free of Alzheimer's. But if only 5% of the general population actually develop Alzheimer's, then even if you fail the test, you are still most probably (67%) in the clear. Granted, it's a reason for concern, because your odds of being in the clear dropped from 95% to 67%, but it's certainly not as big an update of your odds as you might have expected from a 90% accurate test that you just failed. (Right? Or did I screw up the math?)
As this is just more way to get the pre existing condition black list and job based health insurance is slowly fading away as well.
The ACA did kill off the junk plans that some jobs used to offer that did not cover anything any ways.

No. Alternatives have been tried and found to be monumentally disastrous.
I would change my diet very quickly and take up jogging:
Is Alzheimer’s Type 3 Diabetes?

Also, I would look specifically at anti-inflammatory diets, because Alzheimers, like many chronic modern diseases, is linked to chronic inflammation (in this case, in the brain):
> Since the late 1980s, various studies have found hints that the chronic inflammation found in Alzheimer’s hastens the disease process
See the connection?

Inactivity and obesity increase the risk for diabetes, but exactly how is unclear. Recent research suggests that inflammation inside the body plays a role in the development of type 2 diabetes.
The good news: An "anti-inflammatory" diet and exercise plan can help prevent and treat type 2 diabetes.
The effects of inflammation are familiar to anyone who has experienced a bug bite, rash, skin infection, or ankle sprain. In those situations, you will see swelling in the affected area.
With type 2 diabetes, inflammation is internal.

Heh... Easy question, unfortunately.
Top priority: prepare an easy and painless way out. Guns are illegal here, so it would take a bit of thinking, organizing, saving money, etc. Probably the best solution would be an international trip to a clinic that will help me, but I would need a backup plan if someone decided to stop me. Better do it early and be ready for later, with a plan simple enough to execute when the illness already has a significant effect (but before it makes me forget I have that option). Later I may not be able to do this and noone will help me. Hell, I wouldn't even ask for it, I don't want that helpful person to go to jail.
Oh, I could have other priorities, if I could achieve this just by making my wish clear. But as long as euthanasia is not legal here, I'd have to rely on myself, so waiting too long would be risky. I will not reach the final, infant-like stages if I can help it. I prefer to keep my dignity, thank you.
So, this is the most important thing. Number two is obvious too - research into current best practices and applying them (diet, activity, training, whatever). Even if it buys me just a few more months of mostly normal life, it's worth it.
Not to suggest that anyone should do the same. If your views or priorities are different, feel free to do whatever you want.

My familiy is under orders to put me on a jet to Alaska, and from there, a bush plane to as far north as possible, and deliver me to Inuits, with instructions to set me out in the weather as senilicide. For that, I'll make a sizable contribution to the village.
Only an hour or so at -20, and I'll be polar bear food.

While I do understand the ethical dilemma as outlined in TFA regarding the blood test for screening the Alzheimer's disease, I do welcome it.
My reasoning is that if I take that test and it comes out positive (that is, there's a great chance I gonna get hit with it, in coming years / decades) it would at least give me more time to be better prepared.
I can put in my will, before my Alzheimer's disease set in, that any other will that I do, after I'm hit with the Alzheimer's disease must be deemed not valid, for people around me could take advantage of my losing of cognitive ability and change my wish on how I want to allocate what I have left to whom I want to leave it with.
I can also take better care of myself, in terms of cognitive health. Maybe I'll put more time in "brain exercise", or taking less food that may be contaminated with substances that have shown to be related to the Alzheimer's disease, such as Aluminium.

I would volunteer for that one-way mission to Mars!
Of course the trip better not take too long, because of the Alzheimer's progression. If I get there too late, I might make a fool out of myself on the mission:
"Hi, Mars, Bob Flemstein, big fan! I know you're crazy busy with us suicidal visitors and everything, but...could you sign? I don't wanna be that guy, but..."
You'll probably end up getting rolled in Anchorage and get stuck at the Motel 6.
That would be a horrible way to go.
Faster! Faster! Faster would be better!
"Monkey! You left the airlock open again!"
Somehow, it just doesn't strike me as a good idea.

If I knew you were to develop a demence, I'd suggest you settle your pending issues right away, but I don't see a reason not to do that, anyway, You don't know what awaits you at the turn of the corner.
It's not so much "pending issues" I'd want to settle it's more a case of holidays. Having had a father who died of alzheimer's last year my mum was trapped at home with him for several years and got very few trips away. If my dad had known that he was going to develop the disease in a few years then they would likely have taken more holidays, visited family etc. a lot more because there was a limited window to do so. As it was it was about a one year window from diagnosis to my dad being too confused to travel.
This is not the sort of thing that you would do without knowing knowing that you were developing alzheimer's since, if you took all that travel at once, you'd be stuck at home for several years afterwards. So if there is still no cure when I get to the age to worry about alzheimer's I would certainly find a 3 year advance warning useful - it gives you time to visit the family and travel while you know what you are doing. It's also easier to put your affairs in order before you start to suffer from the symptoms since financial matters are hard enough to get right with your full mental faculties.
If something isn't your private property then you forfeit the right to dictate how it is used. So I could take stuff you've worked hard for, and break it, and you have no right to be upset because it isn't yours.

Who wants to know earlier they have a horrible fatal disease? And who wants their insurance company to know that as well?
Professor Bob Nagele (from the med school I'm attending now) has had a blood-based Alzheimer's test since 2011: http://www.plosone.org/article...
Using human protein microarrays to characterize the differential expression of serum autoantibodies in AD and non-demented control (NDC) groups, we identified potential diagnostic biomarkers for AD. The differential significance of each biomarker was evaluated, resulting in the selection of only 10 autoantibody biomarkers that can effectively differentiate AD sera from NDC sera with a sensitivity of 96.0% and specificity of 92.5%.
This is better than carbon monoxide, because nitrogen is completely inert and doesn't leave a hazardous scene for those who are present/recovering your corpse.
Wouldn't a room full of pure nitrogen be just as dangerous to the person recovering you if they also will continue to breath normally
until they black out and die as well?

It would take a little bit of thinking but the best solution if you really wanted to do this would be some sort
of dead man's switch that exploited your forgetfulness. i.e. a drawer that explodes if you open it. A
bottle of soda in the fridge that is poisonous, etc... You could easily have multiple booby traps in your
house rigged to go off if you forget they are there. As long as you were of sound mind, you would know
not to trigger them but how to do this safely without accidently endangering a caretaker would be the tricky
part.
From the author's research page: "His research has received support from the National Science Foundation, the National Institutes of Health (NIH), and the U.S. Department of Defense, among other sources." Irritating, no?
"Consensus" in science is _always_ a political construct.

As compared to most of my relatives, catheterized and on anti-Psychotics, bedridden and bedsores? Wearing diapers so they can shit themselves with impunity. Not knowing who they were, if they were lucky, their skin peeiling off? One took 10 years to die that way.
The good news is the nursing homes took pretty much every cent they had, so the will recipients didn't have anything to fight over. Yeah, that's so much better than freezing to death in a couple hours.

No, and the ACA eliminates the primary motive for snooping on your medical records: denying you coverage.
You'll still get denied coverage if the treatment hasn't been through years of trials and millions of dollars to obtain the "blessing" of the funded-by-pharmaceutical-companies-FDA. That's pretty much always been the case, but now under the ADA it will have to go through a cost-benefit analysis by a board of bureaucrats that may decide it's too expensive, like the NIH does now.
Plus, the ACA by-passes the HIPAA rules that protect your medical records in a number of ways, including supplying access to at least 16 federal bureaucracies by default, ostensibly to ensure you are "complying" with their mandates.

Would you? Would YOU truly do that, if someone trusted you enough to give you stuff that they worked hard for, under the conditions that you care for it and give it back when you're done? Would YOU, Fractoid, be that person to breach that trust?

There is a free 10 minute test that was developed at the UW which has a higher accuracy rate and can be administered by any physician.
Without a blood draw.
I guess if you don't pay for it, you don't realize the cheaper one is the better one.
And the reason for using a physician is that they can follow up with treatment after confirming the diagnosis.

Several civilisations have had dominant concept of communal property, and every civilisation has limited concepts of communal property: air, grazing ground, sea, health service, roads, etc.
Sure, but the idea there would be no private property just doesn't work. Even the Soviet Union backed of of that piece of silliness within a year or two, if not de jure then de facto.
And sure, there have been civilizations with a "dominant concept of communal property". Failed civilizations.
Notice that you're still "giving" stuff, with conditions. Without the idea of private property, you can't give things because you can't own things. And you can't apply conditions, for the same reason. So no, I wouldn't breach that trust, because there would be no gift and nothing for the trust to apply to. It would not exist to be breached.

And really, that is so much better. None of us gets out of here alive, and the concept of fighting in agony to spend that last few seconds is incredibly masochistic.
Anyone thinking this is so awful, simply needs to compare your rather poetic description of an end to life, to the long, and morally bankrupt forced "life" in the Terri Schiavo case. Forcing bodily functions on a corpse that long ago had her brain converted to cerebrospinal fluid is something that an evil doctor in a horror film might do.

Precautions: Do not consume alcohol, do not smoke.Do not eat tinned food or packaged food.Learn new things; stay busy in writing, reading and other things.Engage yourself in activities. Home remedies: Diet plays a very important role in slowing the progress of an Alzheimer patient. Almonds, hazelnuts, vegetable oils, egg yolk, whole grain products and avocado are rich sources of Vitamin E, which plays a role of deterrent to Alzheimer.Various Natural Herbs have medicinal properties that can fight Alzheimer. Herbs like Rosemary, Dandelion, Fenugreek, ginkgo, Brazil nut, stinging nettle, willow, gotu kola, fava beans and horse balm have shown excellent results in Alzheimer’s. It has been proved that consuming pumpkin regularly helps fight the disease. So eating pumpkin is recommended.Sesame oil, sesame seeds and sunflower seeds are used for ages to increase the strength of the brain. Eat lots of carrots to improve memory and health.
