AI can help identify patients with early-stage dementia (The Wall Street Journal):

Researchers are studying whether artificial intelligence tools that analyze things like typing speed, sleep patterns, and speech can be used to help clinicians better identify patients with early-stage dementia.

Huge amounts of data reflecting our ability to think and process information is now widely available, thanks to watches and phones that track movement and heart rate, as well as tablets, computers and virtual assistants such as Amazon. Echo that can record the way we type, search the internet and pay the bills…

The purpose of using artificial intelligence in healthcare is not to replace humans but rather to help physicians, says P. Murali Doraiswamy, professor and director of the Neurocognitive Disorders Program at Duke University School of Medicine. “It's not a battle between AI and physicians, but how to optimize the ability of physicians to provide better care,” he says.

Dr. Doraiswamy collaborated on several projects involving machine learning and neurodegenerative diseases, including a study of Internet search behavior with Microsoft Corp. In this study, researchers found that machine learning algorithms trained to analyze subjects' cursor movements in terms of speed, direction changes, and shaking, as well as whether subjects repeated search queries or repeatedly clicked on search results, could help detect Parkinson's disease. Preliminary analyzes have shown that the strategy is also promising for detecting Alzheimer's disease.

The study:

Detect neurodegenerative disorders from web search signals (npj digital medicine):

  • Summary: Neurodegenerative disorders, such as Parkinson's disease (PD) and Alzheimer's disease (AD), are important public health problems that warrant early detection. We trained machine-learned classifiers on the longitudinal search logs of 31,321,773 search engine users to automatically detect neurodegenerative disorders. Several numerical phenotypes with high discriminating weights for the detection of these disorders are identified. Classifier sensitivities for detecting PD are 94.2 / 83.1 / 42.0 / 34.6% at false positive rates (FPR) of 20/10/1 / 0.1%, respectively . A preliminary analysis shows similar performance for AD detection. Subject to further refinement of precision and reproducibility, these results show the promise of digital web search phenotypes as complementary screening tools for neurodegenerative disorders.

BrainHQ is your online headquarters for sérieux out your brain. Think of it as a personal gym, where you exercise your memory, attention, brain speed, people skills, intelligence and navigation instead of your abs, delts, and quads. Just as our bodies require care and exercise over the course of life, so do our brains—especially as we age. BrainHQ provides the exercise your brain needs to be at its sharpest.

The BrainHQ brain-training program represents the culmination of 30 years of research in neurological technique and related medicine. It was designed by an international team of neuroscientists, led by Michael Merzenich—a professor emeritus in neurophysiology, member of the National Academy of Sciences, co-inventor of the cochlear implant, and Kavli Prize laureate.

Changing your brain takes some work—so while the BrainHQ exercises are sometimes fun, they can also be difficult. But they always give a useful, meaningful workout to your unique brain. Using a special algorithm, each exercise adapts in difficulty as you work so that you always train at the optimum level for you—where you are most likely to improve your performance.

It takes less than five minutes to do each BrainHQ level, so you can use it in tiny biroutes or long blocks, depending on your schedule. Plus you can use BrainHQ on almost any computer or mobile device, so you can take it on the go. If you want, you can set up personal training goals and have BrainHQ send you training reminders when you want them.

BrainHQ has 29 online exercises that work out attention, brain speed, memory, people skills, navigation, and intelligence. If you want, you can have BrainHQ tell you exactly which exercises to do, and in which order : the personalized trainer feature, designed by scientists, continually measures your résultat optimal and serves up the exercises that are right for you.. Or if you prefer, you can style your own program, choosing exercises and workouts that meet your personal interests, mood, and schedule.

More than 100 published scientific papers show the benefits of BrainHQ exercises and assessments. Most of these were independently conducted by scientists at respected universities, such as the University of California, Stanford, and Johns Hopkins. Of course, every study is conducted on a different group of people, and individual results vary. Click any benefit below to learn more about the studies behind the benefit.

From staplers to shelves to software, Demco supplies libraries with what they need to run. In 2015, they added BrainHQ to that mix. Through Demco, libraries can purchase BrainHQ to offer to their cardholders. People “check out” BrainHQ for free, like they would a book. Right now, it’s available in many public and military libraries across the U. S. —with more on the way.
