A systematic review of suggestive seizure induction for the diagnosis of psychogenic nonepileptic seizures
نویسندگان
چکیده
Suggestive seizure induction is a widely used method for diagnosing psychogenic nonepileptic seizures (PNES). Despite seven decades of multidisciplinary research, however, there is still no unified protocol, no definitive agreement on the ethical framework and no consensus on diagnostic utility. This systematic review surveys the evidence at hand and addresses clinically relevant aspects of suggestive seizure induction. In addition to its use for facilitating the diagnostic process, its mechanism of action and utility in elucidating the psychopathology of PNES will be discussed.

The Diagnosis of Psychogenic Nonepileptic Seizures
About 25% of patients seen in epilepsy clinics and monitoring units who do not respond to antiepileptic drugs (AEDs) have received a misdiagnosis.1-3 The eventual diagnosis for most of these patients will be psychogenic nonepileptic seizure (PNES)1,4-a somatoform conversion disorder. It is treatable, but diagnosis, delivery of the diagnosis, and management present significant challenges. A majo...

METHOD A questionnaire pilot study of newly diagnosed psychogenic nonepileptic seizure patients confirmed by video electroencephalography (EEG) was carried out, using a 59-item general symptom questionnaire, wit...
متن کاملPsychogenic (nonepileptic) seizures.
Psychogenic (nonepileptic) seizures are among the most common and serious of all psychogenic neurological disorders. They account for approximately 20% of all intractable seizure disorders referred to comprehensive epilepsy centers and present with a reported annual incidence of approximately 4% that of true epilepsy. These events are serious and disabling. Indeed, compared with patients with t...
متن کاملInforming patients about the impact of provocation methods increases the rate of psychogenic nonepileptic seizures during EEG recording.
Observation of psychogenic nonepileptic seizures (PNESs) during video-EEG represents the diagnostic gold standard for PNESs. Different provocative techniques have been used to increase PNES frequency during EEG. These techniques include placebo administration, suggestion strategies, or both. In order to avoid the appearance of deception, we investigated the following hypothesis: If patients wit...
متن کاملVariables associated with co-existing epileptic and psychogenic nonepileptic seizures: a systematic review
PURPOSE Epileptic seizures (ES) have many mimickers, perhaps the most relevant being psychogenic nonepileptic seizures (PNES). The picture is even more challenging when PNES are associated with ES in a given patient. The aim of this research paper was to delineate the demographic, epileptological and psychiatric profile of that specific population. METHODS A systematic review was carried out ...
