Rationale:
Previous consensus-based ILAE guidelines (Commission Report Subcommission on European Guidelines), the American Society of Clinical Neurophysiology and the Canadian Society of Clinical Neurophysiologists recommend that at least 20 minutes of technically adequate recording should be made during routine electroencephalography (rEEG). This retrospective study assesses the duration of rEEG recording required to detect epileptiform activity (EA) in people with epilepsy (PWE).
Methods:
Routine EEG recordings were analysed for PWE who had experienced at least one seizure in the last 5 years. Each rEEG was performed at the tertiary epilepsy centre of Vilnius University Hospital Santaros Clinics and lasted 30 minutes. The time of the appearance of the first EA was assessed in each recording. The presence of sleep and the latency to sleep onset were also determined. Statistical analysis was performed using MS Excel and R (version 4.2.2), with statistical significance set at p < 0.05.
