A powerful new AI tool developed by the Mayo Clinic is set to transform how doctors detect and diagnose dementia. Named StateViewer, this breakthrough tool uses a single brain scan to accurately identify nine different types of dementia, including Alzheimer’s disease, with high precision.
🧠 What Is StateViewer?
StateViewer is an AI-based diagnostic tool that analyzes an FDG-PET brain scan — a common type of imaging that measures how the brain uses glucose (energy). It identifies subtle brain activity patterns linked to different types of dementia. These include:
- Alzheimer’s disease
- Lewy body dementia
- Frontotemporal dementia
- And six more types
This tool helps doctors:
- Diagnose dementia twice as fast
- Improve accuracy by up to three times compared to traditional methods
📊 How Was the Tool Developed?
The Mayo Clinic team, led by Dr. David Jones, trained the AI on over 3,600 brain scans from both dementia patients and people without cognitive issues. This large dataset allowed the tool to “learn” the unique patterns associated with each dementia type.
Dr. Leland Barnard, Ph.D., led the AI engineering work behind the scenes, ensuring the tool was both clinically accurate and easy to use in real-world settings.
“Behind every scan is a person with urgent questions. StateViewer aims to bring clearer answers, earlier,” says Dr. Barnard.
🔬 Why Early and Accurate Diagnosis Matters
Dementia affects over 55 million people worldwide, with nearly 10 million new cases every year. Alzheimer’s disease alone is now the fifth leading cause of death globally. But detecting dementia early is challenging because:
- Symptoms often overlap
- Diagnosis usually requires multiple tests, including memory exams, blood work, interviews, and specialist referrals
- Differentiating between types of dementia, even for experts, is complex
StateViewer changes that by delivering accurate, data-driven insights from just one scan.
🎨 Visual Diagnosis Made Easy
One of the standout features of StateViewer is its color-coded brain maps. These maps:
- Highlight areas of abnormal brain activity
- Allow even non-specialists to understand what the AI sees
- Improve clinical communication and decision-making
For example:
- Alzheimer’s affects memory-processing regions
- Lewy body dementia targets movement and attention areas
- Frontotemporal dementia impacts behavior and speech
With these visuals, doctors can explain results clearly to patients and caregivers.
🌍 Broader Impact for Clinics and Hospitals
Because StateViewer uses commonly available brain scans (FDG-PET), it has the potential to bring high-quality dementia diagnosis to:
- Smaller clinics
- Rural hospitals
- Facilities without neurology departments
This is a game-changer for equitable healthcare access.
🔮 What’s Next?
Mayo Clinic researchers are now expanding the use of StateViewer to more hospitals and clinical settings. They will continue to evaluate its accuracy, usability, and integration into standard care workflows.
As AI tools like this evolve, they will play a bigger role in:
- Personalized medicine
- Remote diagnostics
- Primary care support
