Validation of a novel classification model of psychogenic nonepileptic seizures by video-EEG analysis and a machine learning approach

Semiological classification of psychogenic nonepileptic seizures

“…This classification system proved to be valid and reliable in its original study 2 . According to this semiological classification system of PNES, we 6 observed that more than half of our patients had generalized motor seizures, while approximately two-fifths had non-motor seizures.…”

“…In conclusion, we observed that the recently proposed PNES classification system by Magaudda, et al 2 is a useful and practical proposal and may provide a good foundation to begin discussions on the definition and classification of PNES in the scientific community. This proposed classification of PNES may address proper diagnosis and provide standardization across future studies and may also potentially shed light on the etiologic understanding and management process of various classes of patients affected with PNES.…”

“…Recently, some experts tried to provide various classification systems for PNES [2][3][4][5][6] . A semiologically focused classification of PNES may address proper diagnosis and provide standardization across future studies 2 .…”

Post–epilepsy surgery psychogenic nonepileptic seizures

“…However, seizure semiology plays an important role in increasing the index of suspicion to make an appropriate diagnosis; emergence of new postoperative seizure semiology may suggest the existence of PNES. A longer duration, a gradual onset, waxing and waning movements, asynchronous movements, pelvic thrusting, closed eyes, and side‐to‐side head movements are often seen in PNES, but none of these manifestations is pathognomonic . Other semiologies may also be seen in PNES including akinetic seizures and seizures with subjective feelings .…”

Psychogenic nonepileptic seizures in pediatric population: A review

“…As regards different semiological types of PNES, in adults the most common one is rhythmic motor (Magaudda et al, ; Wadwekar et al, ), whereas in pediatric studies results are contrasting. Madaan et al () found that dialeptic and mixed semiology are prevalent in pediatric population.…”
