ABSTRACT
OBJECTIVES:
We aimed to estimate the frequency of epileptic seizures (ES) and psychogenic nonepileptic seizures (PNES) with atypical duration in our epilepsy monitoring unit (EMU), in order to raise awareness of atypical durations of both types of events. MATERIALS &METHODS:
We retrospectively reviewed all consecutive video-electroencephalogram (vEEG) recordings in our medical center's EMU from January 2013 to December 2017 and identified patients with seizures with atypical duration. Short PNES were defined as those lasting fewer than 2â¯min and long ES as those lasting for more than 5â¯min.RESULTS:
The files of 830 adult (age >16â¯years) patients were reviewed, of whom 26 patients (3.1%, mean age 33.3⯱â¯9.8â¯years, 12 females) were diagnosed as having an unusual seizure duration. Among 432 patients with ES during monitoring, fourteen patients [3.2% (95% confidence interval (CI) 1.5%-5.0%), mean age 33.0⯱â¯12.2, 5 females [had long ES durations (exceeding 5â¯min). In 64% of patients with long ES, the events were provoked by antiepileptic drug (AED) withdrawal during vEEG, 62% had focal lesion on brain imaging, and 64% had a frontotemporal or a temporal seizure focus. Among 223 patients diagnosed with PNES, 12 patients [5.4% (95% CI 2.2%-8.6%), mean age 33.6⯱â¯6.6, 7 females] had short PNES durations (less than 2â¯min) and demonstrated motor (9/12, 75%), altered responsiveness (6/12, 50%), and vocalization (5/12, 42%) as the most prominent clinical features.CONCLUSIONS:
The data from our case files highlight two main considerations in the diagnosis of paroxysmal events prolonged event can be due to ES, while short events can be psychogenic.Palavras-chave
