From the Guidelines
The most effective approach to AI-based sleep disorder detection combines EEG with other biosignals, including EMG, ECG, and SpO₂, to provide a comprehensive understanding of sleep patterns and improve diagnostic accuracy. Several studies have demonstrated the benefits of integrating multiple physiological signals to detect sleep disorders, such as sleep apnea, insomnia, and narcolepsy. The use of polysomnography, which records various physiological variables during sleep, including electroencephalography, electro-oculography, electromyography, respiratory pattern, snoring, oxygen saturation, transcutaneous carbon dioxide tension, electrocardiography, and body posture, allows for the recognition of events that occur during sleep and offers the advantage of identifying sleep with certainty 1.
- Key benefits of combining EEG with other biosignals include:
- Improved diagnostic accuracy for complex sleep disorders
- Enhanced ability to identify subtle patterns and relationships between different physiological systems during sleep
- Increased sensitivity to detect sleep disorders, such as sleep apnea and insomnia
- The integration of EEG with other biosignals, such as EMG, ECG, and SpO₂, provides complementary information, including:
- Brain activity patterns from EEG
- Muscle movements related to disorders like REM sleep behavior disorder from EMG
- Cardiac abnormalities common in sleep apnea from ECG
- Oxygen desaturation events from SpO₂
- Deep learning architectures, such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs), are typically used to process the various signals simultaneously and improve detection accuracy.
- The SLEEP-EDFX database and MESA Sleep Study have been widely used in research combining multiple physiological signals, demonstrating the effectiveness of this approach in real-world applications.
