Summary:

- The study found that AI models can accurately predict a person's age based on brain scans, with potential applications in early detection of cognitive decline and neurodegenerative diseases.
- The AI models were able to predict a person's age with an accuracy of about 4 years, suggesting that changes in brain structure and function can be detected before clinical symptoms appear.
- The researchers believe this technology could be used to develop personalized interventions and treatments to slow or prevent cognitive aging, potentially leading to improved quality of life for older adults.
