StateViewer's Impressive Performance
The AI tool demonstrated remarkable accuracy, correctly identifying the dementia type in 88% of cases. Moreover, it enabled clinicians to interpret brain scans nearly twice as fast and with up to three times greater accuracy compared to standard workflows

. These findings were published in Neurology, the medical journal of the American Academy of Neurology, on June 27, 2025.How StateViewer Works
StateViewer analyzes fluorodeoxyglucose positron emission tomography (FDG-PET) scans, which show how the brain uses glucose for energy. The AI compares these scans to a large database of confirmed dementia diagnoses, identifying patterns specific to different types of dementia

. For instance:- Alzheimer's typically affects memory and processing regions
- Lewy body dementia involves areas tied to attention and movement
- Frontotemporal dementia alters regions responsible for language and behavior

The tool presents these patterns through color-coded brain maps, providing a visual explanation of the AI's diagnostic reasoning, even for clinicians without specialized neurology training.

Development and Future Implications
StateViewer was developed under the direction of Dr. David Jones, a Mayo Clinic neurologist and director of the Mayo Clinic Neurology Artificial Intelligence Program, in collaboration with Dr. Leland Barnard, a data scientist leading the AI engineering

. The team trained and tested the AI on more than 3,600 scans, including images from patients with dementia and people without cognitive impairment.This innovation addresses a core challenge in dementia care: early and precise identification of the disease, even when multiple conditions are present. As new treatments emerge, timely diagnosis becomes crucial in matching patients with the most appropriate care when it can have the greatest impact.
Expanding Access to Expertise
StateViewer has the potential to bring advanced diagnostic support to clinics that lack specialized neurology expertise. This is particularly significant given the rising toll of dementia worldwide, with Alzheimer's disease now being the fifth-leading cause of death globally.
Mayo Clinic researchers plan to expand the tool's use and continue evaluating its performance in various clinical settings. As the field of AI in healthcare continues to evolve, tools like StateViewer demonstrate the potential of machine learning to provide real-time, precise insights and guidance in clinical medicine, potentially changing the course of devastating neurological diseases.
