Understanding of Rapid Ictal Blinking: Definition Criteria, Prevalence, and Localizing Value

Key Points

• The aim is to define rapid ictal blinking (RIB) and evaluate its frequency and potential for localizing seizures.
• Analysis of blinking rates during seizures.
• Comparison of blinking frequency in different seizure types.
• Proposing a definition of RIB based on observed thresholds.
• Ictal blinking rates were notably higher in patients experiencing occipital seizures.
• A definition of RIB was established as seven or more blinks in any 15-second interval during a seizure.
• RIB is frequent but does not significantly aid in localizing seizure focus.
