Under Review
A Putative Role of Heavy Cannabis Use in Temporal Lobe Epilepsy: A Retrospective Cohort Study
Steven Haworth, Cameron Brace, et al.
Under review — Journal of Neurology
Investigates the relationship between chronic cannabis use and temporal lobe epilepsy using EEG-derived machine learning features. Spectral and connectivity biomarkers extracted from HD-EEG recordings are used to characterize network-level differences in affected populations, with classification performance evaluated across seizure onset zones.
Under Review
Engineering and Clinical Biomarkers for Machine Learning Based Seizure Prediction in Hospitalized Patients
Souvik Phadikar1, Santiago Philibert2, Steven E. Haworth3
Under review — Brain
Identifies and evaluates a comprehensive set of engineering and clinical biomarkers for machine learning based seizure prediction in hospitalized patients. Examines the interplay between EEG-derived signal features and clinical covariates to improve prediction performance in acute care settings, with emphasis on features that generalize across patient populations and monitoring configurations.

Duration of EEG Monitoring Needed to Ensure a Low Risk of Seizure Recurrence in Hospitalized Patients
Parimala Velpula Krishnamurthy1, Santiago Philibert-Rosas2, Steven E. Haworth3, et al.
Journal of Neurology · Vol. 273, Issue 1 · p. 70 · January 2026
Presents a survival analysis of 117 hospitalized patients with electrographic or electroclinical seizures undergoing cEEG at the University of Wisconsin Hospital between 2018 and 2022, establishing data-driven thresholds for monitoring duration after seizure detection. Demonstrates that status epilepticus is the only clinical feature significantly associated with increased recurrence risk, and quantifies the EEG duration required to reduce that risk below 5% — 36.8 hours in patients with status epilepticus and 21.2 hours in those without.

Argus: A CNN-LSTM Architecture for Real-Time Seizure Detection in Long-Term EEG Monitoring
Steven E. Haworth1, Santiago Philibert2, Cameron Brace3
Presents Argus, a multi-scale convolutional and bidirectional LSTM network with an attention mechanism for automated seizure detection. Trained and evaluated on the Temple University Seizure Corpus (TUSZ v1.5.2) using a 22-channel TCP bipolar montage at 200 Hz, achieving 98.06% ROC-AUC. The architecture is designed with clinical deployment in mind, prioritizing low false positive rates in continuous long-term monitoring settings. No manuscript in preparation at this stage.

Classifying Conscious Experience Using Topological EEG Features in Healthy Populations
Steven Haworth, collaborators at Harvard and Beth Israel Medical Center
Investigates the electrophysiologic and network-level features distinguishing conscious experience (CE) from no conscious experience (NCE) during NREM stage 2 and 3 sleep using HD-EEG combined with machine learning classification. In a serial-awakening paradigm across 140 participants and 699 awakenings, spectral power, functional connectivity via lagged coherence, and graph-theoretic metrics including modularity, global efficiency, and rich-club coefficient were extracted and screened using false discovery rate correction. A probabilistic ensemble classifier achieves ROC-AUC 0.80 and average precision 0.80 with stable 5-fold participant-level cross-validation, with the largest discriminating effects observed in posterior alpha, delta, and gamma-to-alpha power ratios.
