ROCHESTER, Minn. — Mayo Clinic researchers have developed a brand new synthetic intelligence (AI) device that helps clinicians determine mind exercise patterns linked to 9 varieties of dementia, together with Alzheimer’s illness, utilizing a single, broadly out there scan — a transformative advance in early, correct analysis.
The device, StateViewer, helped researchers determine the dementia sort in 88% of circumstances, in keeping with analysis printed on-line on June 27, 2025, in Neurology, the medical journal of the American Academy of Neurology.
It additionally enabled clinicians to interpret PET mind scans practically twice as quick and with as much as 3 times higher accuracy than commonplace workflows. Researchers skilled and examined the AI on greater than 3,600 scans, together with photos from sufferers with dementia and other people with out cognitive impairment.
This innovation addresses a core problem in dementia care: figuring out the illness early and exactly, even when a number of situations are current. As new therapies emerge, well timed analysis helps match sufferers with probably the most applicable care when it may well have the best impression. The device might deliver superior diagnostic help to clinics that lack neurology experience.
Dementia impacts greater than 55 million individuals worldwide, with practically 10 million new circumstances annually. Alzheimer’s illness, the most typical kind, is now the fifth-leading reason for loss of life globally.
Diagnosing dementia usually requires cognitive exams, blood attracts, imaging, medical interviews and specialist referrals. Even with intensive testing, distinguishing situations reminiscent of Alzheimer’s, Lewy physique dementia and frontotemporal dementia stays difficult, together with for extremely skilled specialists.
StateViewer was developed below the path of David Jones, M.D. (pictured), a Mayo Clinic neurologist and director of the Mayo Clinic Neurology Synthetic Intelligence Program.
“Each affected person who walks into my clinic carries a novel story formed by the mind’s complexity,” Dr. Jones says. “That complexity drew me to neurology and continues to drive my dedication to clearer solutions. StateViewer displays that dedication — a step towards earlier understanding, extra exact remedy and, in the future, altering the course of those ailments.”
To deliver that imaginative and prescient to life, Dr. Jones labored alongside Leland Barnard, Ph.D., an information scientist who leads the AI engineering behind StateViewer.
“As we had been designing StateViewer, we by no means overpassed the truth that behind each information level and mind scan was an individual dealing with a troublesome analysis and pressing questions,” Dr. Barnard mentioned. “Seeing how this device might help physicians with real-time, exact insights and steerage highlights the potential of machine studying for medical drugs.”
The device analyzes a fluorodeoxyglucose positron emission tomography (FDG-PET) scan, which reveals how the mind makes use of glucose for power. It then compares the scan to a big database of scans from individuals with confirmed dementia diagnoses and identifies patterns that match particular varieties, or mixtures, of dementia.
Alzheimer’s usually impacts reminiscence and processing areas, Lewy physique dementia entails areas tied to consideration and motion, and frontotemporal dementia alters areas liable for language and behavior.
StateViewer shows these patterns via colour-coded mind maps that spotlight key areas of mind exercise, giving all clinicians, even these with out neurology coaching, a visible rationalization of what the AI sees and the way it helps the analysis.
Mayo Clinic researchers plan to increase the device’s use and can proceed evaluating its efficiency in a wide range of medical settings.
