AI being used to diagnose Alzheimer's disease early by reviewing brain scans

A devastating chronic neurodegenerative disease, Alzheimer’s disease (AD) currently affects around 5.5 million people in the United States alone. Causing progressive mental deterioration, it ultimately advances to impact basic bodily functions such as walking and swallowing.

Looking for a way to help, researchers at the University of Bari and Istituto Nazionale di Fisica Nucleare in Italy have developed new machine learning AI technology that may help identify Alzheimer’s a decade before doctors usually can, by way of non-invasive MRI brain scans. An early diagnosis — before any of the symptoms a doctor might recognize become apparent — could give patients a chance to make changes to their lifestyle which may slow Alzheimer’s progression.

“We used publicly available data, consisting of 67 brain MRI scans from the Alzheimer’s Disease Neuroimaging Initiative, including healthy controls and AD patients,” Nicola Amoroso, one of the lead researchers on the project, told Digital Trends. “We used this cohort to feed [our] artificial intelligence, then an independent test of about 148 subjects — including controls,

Alzheimer’s disease and mild cognitive impairment (MCI) subjects — was performed. According to our results, it is possible to distinguish a healthy brain from one with Alzheimer’s with an accuracy of 86 per cent. Crucially, it is also possible to detect the difference between healthy brains and those with MCI with an accuracy of 84 per cent.”

This isn’t the first similar study that involves using cutting-edge technology to help diagnose Alzheimer’s and other neurodegenerative diseases. Researchers at VU University Medical Centre in Amsterdam have also been using MRI scans to try and carry out similar early diagnosis of Alzheimer’s. Another intriguing high tech approach is one being taken at Cedars-Sinai Medical Center, University of Southern California (USC), and University of California, Los Angeles (UCLA), where researchers are working to develop an early diagnosis eye test for Alzheimer’s.

“Our goal is to use our approach for other pathologies,” Nicola Amoroso continued. “In particular, we are now investigating Parkinson’s disease, and preliminary results are really encouraging. It would be very important to support studies and clinical trials to let emerge novel preventive or disease modifying therapies.”

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."
