Technology To Detect Alzheimer's Takes SXSW Prize
An anonymous reader writes "Being able to diagnose people with Alzheimer's disease years before debilitating symptoms appear is now a step closer to reality. Researchers behind Neurotrack, the technology startup that took the first place health prize at this year's South by Southwest (SXSW) startup accelerator in Austin. The company says their new technology can diagnose Alzheimer's disease up to six years before symptoms appear with 100% accuracy."
A good screening test is one that identifies a treatable disease.
Or six years extra for people to try experimental treatments before symptoms kick in. Or six extra years to decide when or how to gracefully leave this world, with dignity.
This device can detect Alzheimer's, and it sure as hell can detect Alzheimer's!
Not quite in line with the data. FTFA "Kaplan said 100 percent of subjects who scored below 50 percent on the test have gone to receive an Alzheimer's diagnosis within six years, while none of those who scored above 67 have developed Alzheimer's." This doesn't equate to 100% accuracy. What happens between 50 and 67%? Plus it doesn't say what the sample size is. Is it 1, 10, 100, 1000? Some more robust statistics would have been nice. They were probably trying to keep it simple instead of confusing people with 99/99, but they could have said "approaching 100%".
GENERATION 27: The first time you see this, copy it into your sig on any forum and add 1 to the generation.
Now they can figure out who has it, before it is too late. I heard it described as "this test is like before mammograms, when a woman found out she has breast cancer It was always stage 4 at that point". Now, with a test, researchers have a better window to fight it.
Claim of 100% accuracy.
A Twitter full of "launch" and "pitch" announcements and not much else.
A website that is nothing more than a placeholder.
Yeah, they're going straight into the history books, they are.
You want me to believe you, publish, and let people rip it apart. If the public-facing part of your whole organisation is talking of nothing more than startup awards and pitches, I don't see how you can be doing proper research, or how you can be selling it to medical establishments. And without bothering to provide evidence of either, I can only assume it's snake-oil.
Drinking from Aluminum cans isn't going to expose you to Aluminum, at least not much. Instead it will expose you to plastics which strongly resemble sex hormones, because the cans are lined with plastic, and all plastic beverage containers leach toxics into their contents.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
It is very easy to make a test that detects 100% of patients who will eventually get a disease. Just make it always say "positive" and you're done. The hard thing is balancing the ability to detect a disease and avoid false negatives (sensitivity) with the ability to detect absence of disease and avoid false positives (specificity). Related to this are the positive predictive negative predictive values. Since Alzheimer's is very difficult to diagnose clinically and the only definitive proof is a biopsy/autopsy, I very much doubt a screening test would exist with a 100 % sensitivity and/or specificity.
There's growing evidence that treating Alzheimer's early, before substantial amyloid plaques have formed, can quite significantly delay the onset of symptoms. You need early screening tools to implement this.
I would welcome the advance notice. I'd like to have a chance to get my affairs in order and do a few things before I'm unable.
Do those things now; you never know when your time is up.
My wife was perfectly healthy until the day before Thanksgiving 2005 when, with only the complaint of a persistent headache, she was diagnosed with a fatal brain tumor known as a Glioblastoma Multiforme (GBM). She died in my arms just seven weeks later; we had been together for 20 years.
While she was 61, I was 42 at that time. We both had Wills and our finances pretty well in order anyway, but now I have a more detailed Will, beneficiaries and/or transfer on death notices on my investments, copies of important paperwork in a firesafe at home, and a Living Will registered at U.S. Living Will Registry that includes a DNR (Do Not Resuscitate) - many hospitals can provide and submit the paperwork and having them do so will also cover the $5/year fee. I have also signed up with the Virginia State Anatomical Program to donate my body to science, like my wife asked me to do for her.
We were lucky and I'm grateful for all our years and those last seven weeks together, including our last Thanksgiving, wedding anniversary, Christmas and New Year. (though, the Winter season suck for me now.) Many people aren't so lucky and the end comes very suddenly.
