#3Great but the big problem is how to actively treat it. Sleep is a huge factor and that’s a problem for us insomniacs :(

#4For a disease which (to my knowledge) can’t be slowed down or reversed, I think it’s a fair question why we would want to detect Alzheimer’s. Maybe there are other reasons, but my suspicion is that we will be able to, and an easy detection method significantly widens the pool of subjects to study later on.
If it turns out that driving a Prius on Tuesdays slows down Alzheimer’s, a larger pool of subjects would allow us to figure that out.

The accuracy of this test is nowhere nearly good enough to do population-wide screening. The clinical setting for this test is memory clinics in which Alzheimers is already relatively highly likely differentially, and even there you're going to get a surprising number of false positives.
(There's enough info in the supplemental link on this page to have an LLM do the Bayes math for you.)

This again?
The test is optional. Feel free to skip it.
Tell 50 million people they’re likely to have Alzheimer’s then tell them where to donate towards a cure, or treatments to slow it by a decade.

Nobody is ever going to do that with this test, because the overwhelming majority of positive test results in a population-wide sample will be false, and the proposed diagnosis is devastating. This is a test for people who already have symptomatic dementia that helps confirm the diagnosis.

I would personally want to know as early as possible, so I could get my affairs in order and register my wishes around end of life care and euthanasia while I am still recognised as having full mental capacity.
It's also better for people around the Alzheimer's patient, as it will let them understand why someone's personality and behaviours may be changing, and possibly let them be bit more forgiving of such changes. It will also give family more time to plan and understand the health and community services and support are offered wherever they live.

There are more personal practical reasons too.
Even though it cannot be reversed or eradicated (yet, let's hope) detection can allow individuals to adopt interventions that help either adjust their lives to better cope with its progression or help mitigate some of the detrimental behavioral consequences. In addition, if you have family to care for it may be impetus to get certain things in order for them before later stages of the disease, etc. It's horrible and bleak, but I could certainly see why one might want to know.
In the lucky case, it can also relieve anxiety. Even though false negatives may still be possible, receiving a negative detection might give people who have anxiety about certain symptoms relief, since they can rule out (rightly or wrongly) a pretty severe disease.

If the patient still has periods of lucidity but the disease is suspected to be advancing, knowing they have it could prompt them to get their legal affairs in order.
