Demonstrates EEG delta/theta phase-coherence features plus ML classifiers achieving high AUC in small clinical cohorts—relevant as signal-processing precedent for EEG biomarker work, though the endpoint is dementia taxonomy not BCI control. Takeaways: coherence features as inputs task-locked oddball protocol generali
- Cognition is tied to long-range cortical connectivity, which can be indexed by phase synchronization of low-frequency EEG (under 8 Hz) between electrode pairs during cognitive tasks.
- The study combined event-related delta (1–3.5 Hz) and theta (4–7 Hz) phase coherence from EEG recorded during a visual oddball task with machine learning to separate groups.
- Participants included healthy controls (n = 24), Parkinson’s disease with mild cognitive impairment (n = 20), Parkinson’s disease dementia (n = 18), and dementia with Lewy bodies (n = 11).
- With delta-band coherence as the classifier input, healthy controls versus Parkinson’s disease with mild cognitive impairment reached an AUC of about 0.79 and 86.4% accuracy.
- Healthy controls versus Parkinson’s disease dementia showed stronger separation, with an AUC near 0.92 and 94.6% overall accuracy.
- Discrimination was higher for healthy controls versus Parkinson’s disease dementia than for healthy controls versus Parkinson’s disease with mild cognitive impairment.
- The work targets discrimination among Parkinson’s disease cognitive stages and dementia with Lewy bodies rather than a brain–computer interface control endpoint.
