Wearable EEG devices in the detection of mild cognitive impairment: a systematic review

1

Wearable EEG devices show promise as accessible tools for screening mild cognitive impairment (MCI) using objective neurophysiological biomarkers.
2

The study analyzed 21 studies on 16 wearable EEG devices, revealing a wide range of classification accuracy from 46% to 95% for MCI detection.
3

Seven critical factors were identified to optimize wearable EEG systems, including moderate channel density and adaptive signal preprocessing.
4

Methodological recommendations for future research include standardizing MCI diagnostic frameworks and optimizing device usability.
5

Insights from this study aim to enhance the real-world application of wearable EEG technology for early cognitive impairment screening.
