“…At our institution, over 85% of admissions were diagnostic, with less than 15% being inconclusive. Such data compares favorably to inconclusive rates of 15-38% reported in previous studies (Ghougassian et al, 2004;Benbadis et al, 2004;Noe and Drazkowski, 2009). The value of such monitoring is apparent when considering the potential consequences of misdiagnosis.…”

“…A study from the Mayo Clinic has shown that the mean time to first seizure is 2 days in VEM. 15 Another study of patients with idiopathic generalized epilepsy found that the mean latency to the first generalized spike-wave discharge was 14 hours, and to the first seizure was 33 hours. 16 A previous study from our institution demonstrated that VEM resulted in a change of diagnosis in 58% of patients and the most substantial increase was seen in the group of patients with PNES, recording an increase from 7% pre-VEM to 31% post-VEM.…”

“…There were no previous studies in which all AEDs were discontinued before the VEEG admission. Interestingly, we and a number of other authors observed no complications related to discontinuation or dose reduction of AEDs [2,9,10,18,19,[21][22][23][24][25]. However, it is too early to conclude that we can discontinue all AEDs from our single series of VEEG monitoring.…”

Purpose:The pur pose of this study was to deter mine the optimal dur ation of long-term video-EEG monitoring (VEEG) in patients with epilepsy. The response time of medical staff to seizures was also evaluated from the viewpoint of safety of the monitoring. Methods: We estimated the optimal duration of VEEG from the seizure onset pattern. We retrospectively investigated all VEEG sessions performed in our department during the period between June 2005 and July 2016. Sessions with no seizures and with only non-epileptic seizures were excluded. Using 91 sessions from 69 patients, information on the onset time and response time of medical staff to seizures was collected. Results: The median duration from the start of VEEG to the first seizure was 2 days. Seventy-seven percent of first seizures occurred within 3 days of VEEG. The median duration from the first seizure to the third seizure was 2 days. Eighty percent of third seizures occurred within 3 days of the first seizure. There was no significant diurnal distribution of seizure occurrence. Medical staff did not respond to 20% of generalized seizures and 69% of focal seizures. The overlooking of generalized seizures occurred mainly during the hours of 1-2 pm and 8-9 pm but there was no significant diurnal pattern in overlooking generalized and focal seizures.Conclusion：Based on these findings, we suggest that VEEG can be terminated when no seizure occurs within 4 days after onset. In our VEEG protocol, in which all antiepileptic drugs were discontinued before the start of a session, there was no diurnal pattern of seizure occurrence. This is the first study investigating the diurnal pattern of overlooking seizures by medical staff during VEEG. Since there was no diurnal pattern to the overlooking, medical staff should pay equal, 24-hour attention to patients on VEEG.
