A new artificial intelligence (AI) tool can predict brain decline years in advance, allowing for early treatment. Researchers at Mass General Brigham developed this tool, which analyzes subtle brain activity changes during sleep using electroencephalography (EEG).
How It Works
The AI was trained using sleep study data from women over 65, tracked for five years. Of the 281 participants, 96 developed cognitive impairment later. By studying brainwave patterns, especially gamma waves during deep sleep, the AI could predict brain decline with 77% accuracy, correctly identifying 85% of those affected.
A New Hope for Dementia Prevention
Lead researcher Dr. Shahab Haghayegh said this tool could change how we prevent dementia. It detects brain wave changes early, offering a chance to take action before symptoms appear.
Why Early Detection Matters
The World Health Organization (WHO) reports that 55 million people live with dementia. Before symptoms start, brain and behavior changes can happen. Early detection can help people make lifestyle changes like exercise, mental activities, and a healthy diet to slow cognitive decline.
Next Steps
While this study is promising, researchers say more studies with diverse groups are needed to confirm the results.
