One Woman Can Smell Parkinson's Disease Before Symptoms Manifest (npr.org) 64

"For most of her life, Joy Milne had a superpower that she was totally oblivious to," reports NPR. Long-time Slashdot reader doug141 explains what happened next: Milne's husband's natural odor changed when he was 31. He was diagnosed with Parkinson's at 45. When Joy walked into a Parkinson's support group, she smelled the same odor on everybody. A Parkinson's researcher tested her with blind samples from early stage patients, late-stage patients, and controls...
NPR tells the story of that test, which took place at the University of Edinburgh with a Parkinson's researcher named Tilo Kunath: [O]ut of all the samples, Joy made only one mistake. She identified a man in the control group, the group without Parkinson's, as having the disease. But many months later, Kunath says, that man actually approached him at an event and said, "Tilo, you're going to have to put me in the Parkinson's pile because I've just been diagnosed."

It was incontrovertible: Joy not only could smell Parkinson's but could smell it even in the absence of its typical medical presentation.

Kunath and fellow scientists published their work in ACS Central Science in March 2019, listing Joy as a co-author. Their research identified certain specific compounds that may contribute to the smell that Joy noticed on her husband and other Parkinson's patients. Joy and her super smelling abilities have opened up a whole new realm of research, Kunath says... Joy's superpower is so unusual that researchers all over the world have started working with her and have discovered that she can identify several kinds of illnesses — tuberculosis, Alzheimer's disease, cancer and diabetes.

Kunath says the ultimate goal is developing a new tool that can detect detect Parkinson's early. "Imagine a society where you could detect such a devastating condition before it's causing problems and then prevent the problems from even occurring."

    • Ya know, I could swear I'd heard about it even before that.. But I have a poor sense of time, so maybe it's only that old.. It really does seem like *forever* ago that I read about this first.

      • Hmm me too - but I might be thinking about dogs smelling cancer or something.... How are we doing with the whole artificial nose thing anyway?

          I'll bet dogs could also easily be trained to smell parkinsons and a ton of other diseases, maybe even covid-19! ... Covid-19 guard dogs!!! Dogs are seriously under-utilised, I bet they could also smell food that would give us food poisoning too. Or tell me when the bloody pears are of perfect ripeness because I can never tell.

          Why aren't we doing this training?

      BBC Scotland news

      One year and nine days old news, to be exact.

    • I've noticed that this seems to be a sort of coronavirus effect. Old stories, historical stories, and other stuff that can be written without research that requires physically interacting with the world is all over the place.

      • I've noticed that YouTube's algorithm has had a sudden change in what it thinks I want to see. It's old stuff that's been around for a while on youtube, but I think it's move up because it doesn't have any of my normal new content to show.

        Mind you, I really don't mind seeing Robin Williams on Johnny Carson/Tonight Show... or Andy Kaufman, but definitely not what it would have dug up for me a few weeks ago.

        • The algorithm includes things that are popular with other people who watch the same things you do, so since more people are watching videos, but the rate of video production is likely normal or even low, the older videos will get a lot of new views and start trending again.

          The algorithm didn't change what it thinks you want to see, it only changed what it thinks people who watch the stuff you watch are watching. And it is right.

      The new thing is the publication in a peer-reviewed, high-impact, western scientific journal. That means that it's very, very, VERY likely a real thing. This isn't a lucky guessing streak or a fraudulent act. People are starting the process of identifying the specific compounds that give the odors and once that's done, a detector isn't all that far behind. That's the big deal, and yes it's a big medical deal.

      Given the range of stuff that's posted here, this definitely rates a slot.
      • Yeah.. I haven't looked at the recent stuff, but the "very likely a real thing" wasn't really an issue before. I remember that she could identify correctly something like 48 out of 50 times. I'm glad for you that you believe its real because it's in a specific journal, but the stuff I saw long ago presented the evidence (and methodology) and it was from a very reputable source. OK, hell, this is so old, it had trickled down to youtube well over a year ago.. It seems that the BBC thing was even a bit old

        • Oh oops.. It was actually 49/50 according to this video, but it seems to be the case that this year+ old video had outdated information in it at the time, and the one person that had been counted as a false positive was later diagnosed (8 months later.. seriously old news!) as having Parkinson's, making her tested accuracy 100%.

      • Given that dogs can be trained to smell for low blood sugar conditions and for cancer, it's not that surprising that random humans can do so as well.

        Good grief, people, this story is important enough to run more than once, unlike a lot of other crap.

        Not everyone in the world reads news for a living and remembers every headline they have ever seen. I follow the news comprehensive at times, but then a big project flares up and I missing everything for weeks or months at a time.

      • In my perspective, we should be finding people like her every day, we just don't have a rigorous research society that want to find this.
        I cite my view after enjoying a few episodes of that Stan Lee show a few years back. besides the people that were flexible, 1 case stood out for me, the guy that could run for a very long time because his body does not produce a specific hormone or acid when the body process fat cells to energy cell ( or something like that ). the guy could run 50 to 100 miles without any

      I understand they're training giant rats in India. They have a better sense of smell than a dog, and can be trained in a fraction of the time. As I recall they're actually on-par or a little better at diagnosing many diseases than a doctor examining a relevant biopsy. I believe they use them to sniff out abandoned explosive mines as well - they're light enough that they probably won't set off the mine - and if they do, a new rat can be trained quickly.

  • Has her sense of smell been tried out on other diseases that have been detected by bloodhounds (malaria, diabetes, certain cancers), or is it focused on substances specific to Parkinson's?

    Imagine a society where you could detect such a devastating condition before it's causing problems and then prevent the problems from even occurring.

    The latter doesn't follow from the former. Both my mom and dad have serious medical conditions, but even though we know we can't keep the illness from progressing further.

      Yes, that's the big problem with something like Parkinsons. Even if you developed a test that can detect the disease years before any symptoms occur . . . . so what?

      There is nothing that can cure Parkinsons, so the only thing that your test does is allow you to tell a person, "You have a disease and it's going to kill you at some time in the future". And what about false positives? What if you tell someone that they are going to develop Parkinsons in the future, and since Parkinsons is currently incurabl

      • We don't have a cure, but I'm pretty sure they have drugs that slow the progress of the disease. Combine those with the ability to detect the disease before there's any obvious symptoms, and you could postpone your decline dramatically.

        >What if you tell someone that they are going to develop Parkinsons in the future, and since Parkinsons is currently incurable they commit suicide.
        In that case, you might want to be really careful not to let them know about these things they call "aging" and "mortality".

        • > We're all going to die at some time in the future - that's the one and only guarantee life comes with You forgot about taxes.
          • Taxes are a recent addition, and more of a guarantee that comes with government rather than life.

    • True. But she noticed the new smell on a particular day, and the Parkinson's slowly manifested itself over the next ten years. This rather suggests that something happened to her husband, or something already within her husband reached some crisis over a period of maybe days, maybe hours. If we could learn something about that period, rather than mapping the degeneration ten years later and trying to slow it down, we might have a chance of prevention.
    • Hi, While what you say is correct. I think the advantages of this,
      even with false positives within the group, is the possibility to find
      when, where or how it happens. What event need to take place
      in order for the disease to rapidly grow.

      Also, which is most likely sci-fi in my head, reprogramming the
      DNA or RNA or whatever needs to have a switch turned on or
      off.

      what is going to be interesting is the newer age related disease
      once we start elongating out life span.

    But I can usually tell if the person in front of me is a sysadmin.

  • Early detection, by itself, won't help us cure Parkinson's since, thanks to dismal funding on basic research, we know very little about how to reverse or halt it.

  • Genes dealt it, she smelt it.

  • There were sporadic reports of pet dogs smelling skin cancer etc.

    The iconic picture during the famine in Somalia of a fat vulture and an emaciated pathetic little child on death bed made one think, why is it waiting for the baby to die, and how would it know? Can vultures smell the diff between life and death?

  • There are beagles trained to react to cancer. I know a doctor who can smell certain diseases. He doesn't tell anyone but his regular diagnosis have always added up.

    It's definitively an effect that is known. Peer review studies on this are good. Even more so if they confirm the effect. Nice. Interesting too.

  • Since many of these "we just don't know" diseases are affected gut bacteria and our buddy, the vagus nerve, I wonder if that's what she's smelling, the chemicals created by the gut bacteria.
  • Train dogs to detect Parkinsons. They sense of smell is 30,000 more sensitive than humans, and you train them the same way Joy was trained: by exposing them for people with and without Parkinsons and rewarding them for alerting on the ones with Parkinsons.

    if a human can smell it, dogs most certainly should be able to.
    much like drugs sniffing dogs, they could be trained to detect these different types of diseases.
