Role of short term out patient video electroencephalography in diagnosis of paroxysmal disorders

ABSTRACT

To distinguish epileptic seizures from non epileptic paroxysmal events, we often use video electroencephalography [EEG] recording. Long term video electroencephalography recording for inpatients is of good value, but, it necessitates much resources [financial and manpower]. There is some evidence suggesting that short term video EEG [STVEEG] is useful, but its role in practice has yet to be evaluated. To assess the usefulness of STVEEG in the diagnosis of different paroxysmal disorders and classifying epilepsy if present. Thirty sex patients had STVEEG recordings [for 2 hours] during a 15 months period. A diagnostic event was recorded in 21 of 36 [58.3%] within the first 2 hours of monitoring PNES [n =11], epilepsy [n=5], and other paroxysmal disorders e.g. syncope, hemifacial spasm, movement disorder [n=5]. STVEEG is a useful diagnostic technique in diagnosis of different paroxysmal disorders and it can be used as a successful screening test for saving other resources like prolonged inpatient video EEG recording
