Duration of epileptic seizure types: A data‐driven approach

Objective To determine the duration of epileptic seizure types in patients who did not undergo withdrawal of antiseizure medication. Methods From a large, structured database of 11 919 consecutive, routine video‐electroencephalograpy (EEG) recordings, labeled using the SCORE (Standardized Computer‐B...

Description
Summary:Objective To determine the duration of epileptic seizure types in patients who did not undergo withdrawal of antiseizure medication. Methods From a large, structured database of 11 919 consecutive, routine video‐electroencephalograpy (EEG) recordings, labeled using the SCORE (Standardized Computer‐Based Organized Reporting of EEG) system, we extracted and analyzed 2742 seizures. For each seizure type we determined median duration and range after removal of outliers (2.5–97.5 percentile). We used surface electromyography (EMG) for accurate measurement of short motor seizures.
