Thanks to Artificial Intelligence, Scientists can Now Predict Dementia Before it Happens

One of the things that would be good to be able to determine years in advance are diseases such as dementia. The prognostic capabilities would give patients and their families time to prepare, as well as plan and manage treatment and care. Fortunately, this no longer seems like a wishful thinking, because an artificial intelligence research has been done at McGill University and it shows this kind of prediction will soon be available to clinics everywhere.

Using artificial intelligence techniques and big data, scientists from the Douglas Mental Health University Institute’s Translational Neuroimaging Laboratory at McGill managed to develop an algorithm which can recognize the signatures of dementia two years before it happens, and all that by using a single amyloid PET scan of the brain of patients at risk of developing Alzheimer’s disease. A new study published in the journal Neurobiology of Aging is where you can find their findings.

According to Dr. Pedro Rosa-Neto, co-lead author of the study and Associate Professor in McGill’s departments of Neurology & Neurosurgery and Psychiatry, this technology is going to change the way physicians treat patients and speed up the research into Alzheimer’s disease.

Dr. Serge Gauthier, co-lead author and Professor of Neurology & Neurosurgery and Psychiatry at McGill added that with the tool being used, clinical trials could focus only on individuals with a higher likelihood of progressing to dementia within the time frame of the study. In his opinion, this will reduce the cost and the time necessary to conduct these studies by a great measure.

It’s been a long-known fact for scientists that a protein called amyloid is found growing in the patients’ brains that have mild cognitive impairment (MCI), a condition that often leads to dementia. Even though the protein starts accumulating decades before the actual dementia starts, the doctors couldn’t use it as a reliable predictive biomarker because not all those who have MCI would continue to develop Alzheimer’s disease.

McGill researchers used data available through the Alzheimer’s Disease Neuroimaging Initiative (ADNI), which is a global research effort in which participating patients agree to complete a variety of imaging and clinical assessments, to start their study.

Sulantha Mathotaarachchi, a computer scientist from Rosa-Neto’s and Gauthier’s team, used hundreds of amyloid PET scans of MCI patients from the ADNI database to train the team’s algorithm to identify which patients would develop dementia, with an accuracy of 84%, before symptom onset. Research is still in progress so researchers can find other biomarkers for dementia that could be included into the algorithm so the software’s prediction capabilities can be improved.

And although this new software is available online for scientists and students to check it out, physician won’t be able to use this tool in clinical practice yet. Not until it gets a certification by health authorities. While that is waiting to be done, the McGill team is doing more testing to make sure the algorithm is valid in different patient cohorts, particularly those with concurrent conditions such as small strokes.

  14. After going over a handful of the articles on your blog, I really appreciate your technique of writing a blog. I bookmarked it to my bookmark site list and will be checking back soon. Please visit my website as well and tell me what you think.|

  15. What a material of un-ambiguity and preserveness of valuable experience regarding unpredicted feelings.|

  16. I’m now not positive the place you’re getting your information, but great topic.

    I must spend a while studying more or working out more.
    Thank you for magnificent info I was on the lookout for this information for my mission.

  17. Hello there I am so grateful I found your webpage, I really found you by error, while I was looking on Aol for something else, Nonetheless I am here now and would just like to say thank you for a tremendous post and a all round exciting blog (I also love the theme/design), I don’t have time to go through it all at the moment but I have book-marked it and also added your RSS feeds, so when I have time I will be back to read more, Please do keep up the excellent work.|

  18. First of all I want to say great blog! I had a quick
    question which I’d like to ask if you don’t mind. I was curious to know how
    you center yourself and clear your mind before writing. I have had a hard time clearing my thoughts
    in getting my ideas out there. I do take pleasure in writing however it just seems like the first 10
    to 15 minutes are generally wasted just trying to figure out how to begin. Any suggestions or
    hints? Thanks!

  19. I think that everything posted was very reasonable.
    But, think about this, suppose you were to create a
    killer title? I ain’t suggesting your content
    is not good., however suppose you added a post title that makes people
    want more? I mean Thanks to Artificial Intelligence, Scientists can Now
    Predict Dementia Before it Happens is kinda plain. You could peek at
    Yahoo’s home page and watch how they create news headlines to
    grab viewers interested. You might add a related video or a pic or two to get people excited about what
    you’ve written. Just my opinion, it would bring your website a little bit more interesting.

  20. Hi to all, it’s in fact a pleasant for me to pay a
    visit this web page, it consists of valuable Information.

  21. Link exchange is nothing else but it is only placing the other person’s weblog link on your page
    at appropriate place and other person will also do same in support of

  22. Wow, marvelous weblog structure! How lengthy have you been running a blog for?
    you make blogging glance easy. The overall glance of your website is excellent, let alone
    the content material!

  23. We’re a group of volunteers and starting a new scheme in our community.
    Your web site provided us with valuable information to work on. You’ve done a formidable job and our
    entire community will be grateful to you.

  24. Spot on with this write-up, I really believe that this website needs much more attention. I’ll probably
    be back again to see more, thanks for the advice!
