Objective: This study investigated sensitivity and false detection rate of a multimodal automatic seizure detection algorithm and the applicability to reduced electrode montages for long-term seizure documentation in epilepsy patients.
Methods: An automatic seizure detection algorithm based on EEG, EMG, and ECG signals was developed. EEG/ECG recordings of 92 patients from two epilepsy monitoring units including 494 seizures were used to assess detection performance. EMG data were extracted by bandpass filtering of EEG signals. Sensitivity and false detection rate were evaluated for each signal modality and for reduced electrode montages.
Results: All focal seizures evolving to bilateral tonic-clonic (BTCS, n=50) and 89% of focal seizures (FS, n=139) were detected. Average sensitivity in temporal lobe epilepsy (TLE) patients was 94% and 74% in extratemporal lobe epilepsy (XTLE) patients. Overall detection sensitivity was 86%. Average false detection rate was 12.8 false detections in 24h (FD/24h) for TLE and 22 FD/24h in XTLE patients. Utilization of 8 frontal and temporal electrodes reduced average sensitivity from 86% to 81%.
Conclusion: Our automatic multimodal seizure detection algorithm shows high sensitivity with full and reduced electrode montages.
Significance: Evaluation of different signal modalities and electrode montages paces the way for semi-automatic seizure documentation systems.

Aspiration of the nasopharyngeal airway (NPA) is one of the rarest and life-threatening complications. In the literature, very few cases have been reported. The advent of NPA to protect the airway in semiconscious patients acts like a double-edged sword, based on the patient's condition.

Objective: Sunflower syndrome is a rare photosensitive childhood-onset epilepsy, featuring repetitive handwaving events (HWE) triggered by light. Objective documentation of these HWE can be difficult due to the numerous events occurring daily and/or caregivers who document the seizures but are not always present. Hence, seizure diaries can be underreporting.

Introduction: A significant proportion of patients do not achieve seizure freedom despite treatment attempts with two different anti-seizure medications (ASMs). A subset may not truly have drug-resistant epilepsy ("pseudoresistant"), while rapid referral of patients with genuine drug-resistant epilepsy to surgery is mandated. This study was designed to evaluate a structured and intensive treatment course with the objective of promptly identifying cases of pseudoresistance and accelerating the time to referral to epilepsy surgery.
