Psychogenic non-epileptic seizures: A model of their pathogenic mechanism
Psychogenic non-epileptic seizures (PNES) consist of paroxystic events facilitated by a dysfunction in emotion processing. Models explaining the pathogenic mechanisms leading to these seizure-like episodes are limited. In this article, evidence that supports dysfunction at the level of arousal tolerance, cognitive-emotional information processing and volitional control is reviewed. A hypothetic...
متن کاملPsychogenic non-epileptic seizures.
Psychogenic non-epileptic seizures (PNES) need to be differentiated from epileptic seizures as the management varies for both. Presence of tongue biting, falling and urinary incontinence favors a diagnosis of epileptic seizures. We report two children with features suggestive of epileptic seizures that were eventually diagnosed as PNES with the help of video-EEG monitoring.
متن کاملNon-Epileptic Psychogenic Seizures: a Neurologist’s Perspective
Psychogenic non-epileptic seizures (PNES) represent a relatively frequent challenge for clinicians. While they resemble epileptic seizures, they are not the consequence of paroxysmal electrical discharges in the brain, but are related to psychological triggers in vulnerable subjects. Gold standard of PNES diagnosis remains the recording of a typical event under video-EEG. PNES recognition is no...
متن کاملPsychogenic non-epileptic seizures: a case report.
Psychogenic Non-Epileptic Seizures (PNES) are paroxysmal episodes of altered behavior that superficially resemble epileptic seizures but lack both the expected electroencephalographical epileptic changes and the association to dysfunction of central nervous system. They account for 17 to 30% of the population admitted to epilepsy units of tertiary hospitals for evaluation of seizures refractory...
متن کاملIctal injury in psychogenic non-epileptic seizures
PURPOSE Whilst ictal injuries in psychogenic non-epileptic seizures (PNES) have been reported previously, very few studies have described the spectrum of ictal injuries in these patients. In the current study, we tried to determine the spectrum of reported ictal injuries associated with PNES and to investigate the possible associated risk factors. METHODS All patients with PNES were recruited...
