AI fast-tracks dementia diagnoses by tapping into 'hidden information' in brain waves

By pairing AI and EEG tests, the team at the Mayo Clinic Neurology AI Program was able to identify specific types of dementia sooner than they would have with human analysis....                        ...                        ...                            ...As dementia becomes more widespread, Mayo Clinic researchers believe that You are not allowed to view links. Register or Login is the key to enabling earlier and faster diagnoses.......By pairing AI and EEG (electroencephalogram) tests, the team at the Mayo Clinic Neurology AI Program (NAIP) in Rochester, Minnesota, was able to identify You are not allowed to view links. Register or Login sooner than they would have through human analysis.......Based on these findings, EEGs could eventually provide a more accessible, less expensive and less invasive way to assess brain health earlier, according to a hospital press release.......You are not allowed to view links. Register or Login......The research was published last week in the journal Brain Communications.......With an EEG, a technician attaches small metal electrodes to the patient's scalp, which measure electrical activity in the brain.......The test produces a recording of wavy lines that represent the brain's electrical impulses. ......It is primarily used to diagnose epilepsy, but can also be used to identify other brain conditions, according to Dr. David Jones, a practicing clinician specializing in behavioral neurology, who directs the You are not allowed to view links. Register or Login program at Mayo Clinic in Minnesota.......You are not allowed to view links. Register or Login......The clinic performs thousands of EEGs each year to evaluate patients with You are not allowed to view links. Register or Login.......It's been known for some time that brain wave patterns change in patients with dementia or cognitive problems caused by Alzheimer's disease or Lewy body disease, Jones said in a phone interview with Fox News Digital......."However, it takes a lot of specialized analysis, expertise and manual labor to extract that information, so Alzheimer's and dementia are not routinely assessed on EEG."......With this study, the researchers set out to find "hidden information" in patients' brain waves using computer algorithms, without manual labor, Jones said.......The AI tool was built in-house at Mayo Clinic, trained on data from more than 11,000 patients who received EEGs over a decade-long period.......In analyzing You are not allowed to view links. Register or Login, the model identified six specific patterns that appeared in patients with Alzheimer's or Lewy body disease that were not found in those who had no cognitive trouble, according to Jones.......The correlation was confirmed by also looking at other measures, such as cognitive testing, blood biomarkers and brain PET scans.......You are not allowed to view links. Register or Login......Overall, the AI tool decreased the EEG reading time by 50% and increased the accuracy of those readings "pretty significantly," Jones said......."This tells us that there is a lot of unused information in clinically acquired EEGs that we can extract automatically — and now we can begin to build better tools, algorithms and methods," Jones said.......It would be "very difficult" to perform this type of analysis at scale without AI or machine learning technology, according to the neurologist.......Harvey Castro, a Dallas-based board-certified You are not allowed to view links. Register or Login and national speaker on artificial intelligence in health care, was not involved in the study but referred to Mayo Clinic's research as "a significant leap forward."......"This technology can rapidly and precisely analyze brain wave patterns, identifying early signs of dementia often invisible to the human eye," he told Fox News Digital.......As an ER doctor, Castro said he does not typically use EEGs due to the time required to interpret the results......."However, You are not allowed to view links. Register or Login allows for fast processing of large amounts of data, facilitating quicker, more informed decisions about a patient's cognitive health," he said. ......"As a result, I can see this becoming a new tool for me to use in the ER."......AI-driven EEG analysis could be a "game-changer" in rural and underserved areas, according to Castro. ......"It provides a cost-effective, non-invasive method to You are not allowed to view links. Register or Login early, where advanced diagnostic tools like MRIs or PET scans are limited."......The ultimate goal is to include this AI-driven EEG analysis into a "multimodal" approach to dementia testing, according to Jones......."That means being able to model brain scans, blood work, cognitive tests and brain waves into one complete model of You are not allowed to view links. Register or Login," he told Fox News Digital.......You are not allowed to view links. Register or Login......The next step is to implement the AI tool into routine clinical practice......."So if you're coming in and having an EEG for epilepsy or a You are not allowed to view links. Register or Login, we'll also simultaneously be able to tell you something about your cognitive health, and whether we see something that means you might need to see a behavioral neurologist," Jones said.......In the future, the neurologist envisions EEGs becoming a "highly scalable and portable" technology, where people can even perform cognitive assessments remotely — "in the same way that you measure You are not allowed to view links. Register or Login or heart rate in your own home."......There are still You are not allowed to view links. Register or Login ahead before this technology becomes widely accessible, Jones noted.......Despite the benefits of this type of technology, Castro cautioned that there are challenges with integrating AI into clinical practice. ......"These include the need for substantial training for health care professionals to use these tools effectively and the potential for over-reliance on AI at the expense of clinical judgment," he told Fox News Digital.......It's also important to balance the use of AI with a "human touch," Castro said.......You are not allowed to view links.
