Good as in scientifically proven. Not speculative fantasy.
As someone with family affected by this disease, it’s a very personal choice whether you want to know or not, but I wish people understood that there are many things you can do with it, particularly for those who will be there for you if/when it hits.
Taking care of a loved one with this disease is extremely hard, and it’s even harder when they haven’t had any chance to prepare for this eventuality. Stuff like written records of your history (health, life, etc.), clear powers of attorney, and so on.
It also makes things much easier for healthcare professionals.

For some reason, taxi drivers seem to have a dramatically lower risk of it.

> Early detection of Alzheimer’s disease is important since the first treatments capable of slowing the progression of the neurodegenerative disease recently became available to patients, and these drugs are more effective when started sooner rather than later.
Clearly the goal is to be able to prevent the disease from progressing or slow it significantly, but are we really there yet even if we have a test?
The risk of dangerous side effects seems to be much higher for those with APOE4 — before approving the treatment they required among other things a genetic test ruling that out. (There are several other genetic variants that predispose to Alzheimer’s, fwiw.) We were lucky and saw none of the concerning side effects.
Are we “there” yet? Where’s there?
The prognosis after this treatment is a massive improvement over what it would have been at this stage of progression if it had been reached even 5 years ago.
If you can detect the disease even earlier and halt progress at a point where you retain more cognitive function, that’s a huge win — and gives you time to wait it out a bit longer in hope that we’re able to develop a treatment that doesn’t just pause but can reverse progression.
Yeah, I doubt we’re ready yet to administer these drugs to people who are asymptomatic (not to mention how pricey they currently are). But for someone who likely has the genes for it, just _knowing_ would in some ways be a relief.
I suppose my point on "are we there yet?" is that the benefit of knowing is limited when there aren't any preventative treatments you can take. I can see both sides but I'm not sure I'd want to take such a test.
For me, this one doesn’t seem to have enough accuracy to be worth the trouble.
But a few years of improvements and maybe a blood test like that is what you need to get insurance to cover a baseline neurological evaluation plus re-evaluation every few years to see whether it’s time to start aggressive treatment.
Maybe in another decade aggressive treatment will be available for disease at earlier stages and good enough to prevent progression at all and maintain nearly full quality of life.
This isn’t a game changer right now, but every time something like this makes it through trials it gives me a bit more hope that we will in fact beat this thing. Likely within my lifetime. Maybe even before I succumb to it.
With the original course of treatment complete we then transitioned to a maintenance regimen of … I can’t remember the name off the top of my head but it’s the other one that’s similar but a bit less aggressive — they had originally presented it as one of the possibilities when we were deciding to start treatment. They’re also adding on a neuroplastocity-enhancing drug as a complement, along with some occupational therapy.
Best of luck to you and your family!
