Short-term outpatient EEG video with induction in the diagnosis of psychogenic seizures

Abstract

To analyze the yield of short-term outpatient EEG video monitoring, the authors reviewed data on all patients who underwent this procedure at their center. All patients were suspected of having psychogenic nonepileptic seizures (PNES) on clinical grounds. The total number of cases of short-term outpatient EEG video monitoring was 74. In 49 (66%) cases, the suspected diagnosis of PNES could be confirmed, thereby obviating the need for prolonged inpatient EEG video monitoring.

The efficacy of routine hyperventilation for seizure activation during prolonged video-electroencephalography monitoring

“…6,15,19 The main limitation of our study is that it is a retrospective analysis of an inpatient population, which may contribute to the current findings, especially in patients who have partial seizures. Further study of routine HV during EEG recording in patients who have partial seizures is required; repeated, prolonged cycles of HV might improve the yield of this procedure, especially in the outpatient setting.…”

Life after being diagnosed with psychogenic non-epileptic seizures (PNES): A South African perspective

“…A video-EGG telemetry unit, which makes use of monitoring individual brain and seizure activity over a period of time, may also be used to ensure an accurate diagnosis [20].…”

Usefulness of prolonged video–EEG monitoring and provocative procedure with saline injection for the diagnosis of non epileptic seizures of psychogenic origin

“…Benbadis et al and Bhatia el al performed short term VEEGM combined with induction protocols [3,4]. Those methods, which are cost-effective, raise some diagnostic problems.…”
