abstract: > | ||
Epilepsy is a prevalent neurological disorder characterized by recurring | ||
seizures, affecting approximately 50 million individuals globally. Given the | ||
potential severity of the associated complications, early and accurate | ||
seizure detection is crucial. In clinical practice, scalp | ||
electroencephalograms (EEGs) are non-invasive tools widely used in seizure | ||
detection and localization, aiding in the classification of seizure types. | ||
However, manual EEG annotation is labor-intensive, costly, and suffers from | ||
low inter-rater agreement, necessitating automated approaches. To address | ||
this, we introduce a novel deep learning framework, combining a convolutional | ||
neural network (CNN) module for temporal and spatial feature extraction from | ||
multi-channel EEG data, and a transformer encoder module to capture long-term | ||
sequential information. We conduct extensive experiments on a public EEG | ||
seizure detection dataset, achieving an unweighted average F1 score of 0.731, | ||
precision of 0.724, and recall (sensitivity) of 0.744. We further replicate | ||
several EEG analysis pipelines from literature and demonstrate that our | ||
pipeline outperforms, current state-of-the-art approaches. This work provides | ||
a significant step forward in automated seizure detection. By enabling a more | ||
effective and efficient diagnostic tool, it has the potential to | ||
significantly impact clinical practice, optimizing patient care and outcomes | ||
in epilepsy treatment. | ||

This database is a subset of the TUH EEG Corpus that was collected | ||
from archival records of clinical EEG at Temple University Hospital | ||
recorded between 2002 – 2017. From this large dataset, a subset of | ||
files with a high likelihood of containing seizures was retained | ||
based on clinical notes and on the output of seizure detection | ||
algorithms. | ||
V2.0.0 contains 7377 .edf files from 675 subjects for a total | ||
duration of 1476 hours of data. The files are mostly short | ||
(avg. 10 minutes). The dataset has heterogeneous sampling frequency | ||
and number of channels. All files are acquired at a minimum of 250 | ||
Hz. A minimum of 17 EEG channels is available in all recordings. | ||
They are positioned according to the 10-20 system. | ||
The annotations are provided as .csv and contain the start time, | ||
stop, channel and seizure type. | ||
