Resumen:
Purpose : Categorize semiological features observed inpsychogenic nonepileptic seizures (PNES) during Video-EEG (VEEG) monitoring to improve clinical diagnosis.Method : Retrospective observational study in patients(p)admitted to VEEG during 2014?2018. Recording of patientswith PNES, with or without epilepsy, were reviewed.The semiology of each event was visually analyzed andentered into a database, in which the signs and symptomswere classified in four groups according to the prominentsemiological finding: Hypermotor, Motionless, Total lack ofResponsiveness and the presence of Aura. Other symptomswere also included.Results : 379 Video- EEG studies were performed duringthe period studied, 53p (14%) met the inclusion criteria, 42(79%) women. A total of 259 PNES were analyzed; 34p wereclassified in the PNES- only group and 19 in the PNES andEpilepsy group. Mean age was 33 yr (15 to 83). Mean onset ofPNEs was 26 yr. Average time before diagnosis was 6 yr. Firstevent was recorded after 16 hr in VEEG (1?90 hr). Numberof events was 4 (1 to 30). As for the treatment, 98% were onmedication with AEDs, mean 4 AED′s (1 to 7). Accordingto the semiological characterization, 40p (75.5%) presented137 Hypermotor PNES, followed by Aura in 36p (68%)presenting 53 PNES. The Total lack of Responsiveness typewas present in 15p (28.3%) with 32 PNES, and Motionlesstype in 11p (20.7%) with 20 PNES.Conclusion : VEEG is the study of choice for the diagnosisof PNES, since it is a dependent operator study, definingthe semiological features of PNES results in a most precisediagnosis. In our study we found that most of the patientspresented with multiple crisis with non- stereotyped events.The most frequent clinical presentation was hypermotorPNES. Thoroughly observation of VEEG recordings bytrained personal is essential to accomplish an accuratediagnosis of PNES.
