“…If inconclusive, overnight EEG/polygraphic recording is indicated [30,97,106]. A few data suggest that ambulatory EEG might be an alternative procedure [107]. Epileptic activity can occur in a (sub)continuous, periodic or fragmented fashion and the topography can be diffuse, unilateral, focal or multifocal [30,32].…”

“…al 13 indicates the average time to first event occurring around 21.8 hours, ranging from 1 to 115 hours after starting the ambulatory recording. Critically, this study's sample included a broad age range (12–101 years), which may have impacted these findings, as optimal duration for event capture may not be equivalent among adult, pediatric, 14 and geriatric populations 15 due to differences in the common types of epileptic syndromes in these life stages.…”

Objective Ambulatory video EEG allows for extended recording of EEG in the comfort of a patient's home. However, the optimal duration of recording to capture clinical events is yet to be established. The current study uses retrospective analyses to identify an optimal recording duration for at‐home video EEG. Methods A retrospective review was performed utilizing an anonymized database of ambulatory video EEG recordings performed between March and September 2020 with a national in‐home EEG provider. Only completed assessments with neurologists' reads of raw data were reviewed, resulting in 3644 unique studies divided into three age cohorts: pediatrics (n = 941), adult (n = 2020), and geriatric (n = 683). Cohorts were characterized by assessment yield and time to first typical clinical event, as well as subsequent typical events over duration of recording. Results Frequency distributions reveal over half of first events are captured within 12 hours, but longer recording durations capture a much wider majority of both first typical events, as well as the mean number of subsequent events (5 clinical events). In 72 hours, over 97% of first events were observed in adult and geriatric patients, as well as over 95% of the mean number of subsequent events. In children, time to first event was significantly earlier than either adult or geriatric samples, with 98% of first events, and 92.8% of the mean number of subsequent events being observed in 48 hours. Significance These results from a large‐scale, national dataset of patients using in‐home EEG monitoring suggests recording at least 48 hours in duration for children, and at least 72 hours in duration for adult and geriatric samples, is optimal to maximize the likelihood of observing typical clinical events to facilitate diagnosis.

“…EEG-video recording is the mainstay of epilepsy centers; however, epilepsy monitoring units (EMU) frequently have long backlogs, waiting periods, and require patients to be in-hospital for several days. 1 To date, most literature on ambulatory EEG monitoring refers to EEG without video [2][3][4][5][6][7][8][9][10][11] and EEG-video has long been assumed to be an inpatient procedure. As of the past decade, technology has made ambulatory EEG-video possible.…”

Introduction The availability of ambulatory EEG-video monitoring gives an alternative to traditional inpatient EEG-video, but its yield and diagnostic value are not well known. This study evaluates the yield of ambulatory EEG-video for the diagnosis of epilepsy. Methods We retrospectively reviewed the ambulatory EEG-video monitoring data from 200 consecutive and unselected patients aged 12 years and older performed by a single company (RSC Diagnostic Services) between January 2018 and May 2018. Studies were processed by two senior certified long-term monitoring EEG technologists and interpreted by neurologists. Results Of the 200 patients, 130 (65%) were women, mean age was 45 years. Mean duration of studies were 76.6 hours (range 23-175 hours). There were 110 studies (55%) with events recorded and 101 (92%) were captured on video. Epileptic events accounted for 17.8% (18/101) of the events captured and 9% (18/200) of our total cohort. Nonepileptic diagnosis accounted for 38% of the total number of patients in study (76/200). Conclusion Ambulatory EEG-video monitoring may be a useful alternative to inpatient epilepsy monitoring unit, particularly with high clinical suspicion for nonepileptic events.
