Summary
This study introduces a novel electroencephalography (EEG) analysis method for diagnosing Alzheimer's disease (AD). The data-driven approach achieves over 80% accuracy, aiding early detection and improving patient outcomes.
Area of Science:
- Neuroscience
- Medical Imaging
- Artificial Intelligence
Background:
- Alzheimer's disease (AD) is a neurodegenerative disorder marked by protein accumulation and neuronal damage.
- Electroencephalography (EEG) is a cost-effective, non-invasive tool for AD diagnosis, but faces noise and analysis challenges.
Purpose of the Study:
- To develop a novel, data-driven methodology for accurate Alzheimer's disease diagnosis using EEG.
- To enhance the diagnostic capabilities of EEG for neurodegenerative disorders.
Main Methods:
- A three-stage approach: signal pre-processing, frame-level classification, and subject-level classification.
- Utilized Convolutional Neural Networks (CNNs) for feature extraction from spectrograms, scalograms, and Hilbert spectra.
- Implemented feature fusion and selection for robust frame-level and subject-level AD classification.
Main Results:
- The proposed model achieved over 80% accuracy, 82.5% sensitivity, and 81.3% specificity in distinguishing AD patients from healthy controls.
- Demonstrated strong performance in subject-level classification for Alzheimer's disease detection.
Conclusions:
- The model offers significant clinical implications for early and accurate AD diagnosis, potentially reducing misdiagnosis rates.
- Further refinement is needed to improve efficacy for differentiating AD from other neurodegenerative disorders like frontotemporal dementia (FTD).
