Bio-impedance spectroscopy-based classification of mental acuity in university students via machine-learning and deep-learning approaches.

Summary: Can a quick body scan tell how sharp your brain is today? Scientists tested university students using a safe, painless tool that measures body water and metabolism with tiny electrical signals. They found that students with better body cell health and hydration had sharper minds. By feeding these scan pictures into a smart computer program (called deep learning), the computer could guess a student's mental sharpness with 98% accuracy! This means we might soon use simple, quick body scans to keep track of our brain health and catch problems early.
