The main use of AEEG is the characterization of patients with non-epileptic events, in patients with a diagnosis of epilepsy that is not clear, and quantification of spikes and seizures to improve the medical management. In this study, we found that AEEG has a high diagnostic yield (72%) and believe that careful selection of patients is the most important factor for a high diagnostic yield. Three patients were referred for epilepsy surgery without the necessity of video-EEG telemetry. In only 1 patient was the AEEG inconclusive due to non-physiological artefacts. For 28 (28%) patients, the AEEG did not provide information on diagnosis because no events or epileptiform activity occurred. For 73 (72%) patients, the AEEG provided information that was useful for the management. The mean duration of AEEG recording was 32 ± 17 hours (15-96 hours). The primary reasons for the AEEGs were subdivided into four categories: a) to differentiate between seizures and non-epileptic events b) to determine the frequency of seizures and epileptiform discharges c) to characterize seizure type or localization and d) to potentially diagnose epilepsy. Most of the patients had at least one previous routine EEG (93%). The mean age of the group was 36.6 ± 16.1 years. Our population consisted of 45 males (44.6%) and 56 females (55.4%). One hundred and one patients undergoing AEEG were prospectively recruited during a three-year-period. The yield of AEEG was assessed by taking into account the questions asked by the clinician before and after the investigation. Over a period of three years, 101 patients were included. This is a prospective cohort study performed in a Canadian academic centre in order to assess the yield and tolerability of AEEG in the adult population. This work-in-progress study aims to address this gap through the design of a low-cost, easy-to-use, and effective EEG headset for engineering educational research studies.Ambulatory electroencephalography (AEEG) is a monitoring technique that allows the recording of continuous EEG activity when patients are at home, without the necessity of admission to the hospital for prolonged video-EEG monitoring.

However, commercially available EEG devices are often either prohibitively expensive, or do not offer the correct capabilities such as enough electrodes. There is potential for such a device to provide insight into learner behavior in the remote learning environment due to its lower cost, light weight, and small size.ĪB - Electroencephalography signals are used widely in medical and pedagogical research because they quantitatively and non-invasively reflect brain activity. This exploratory study provides a framework for future studies when more data could be collected.
Additionally, no distinct conclusion could be drawn from the signal quality comparison between the current design and the commercial device due to limited sample size and large variation among collected data.

For example, although most participants found the authors’ current design to be more comfortable than commercially available designs, the design also had a much larger range of reported comfort levels. The current study includes a relatively small sample size (N=6) however, it does identify some preliminary trends. This work-in-progress study aims to address this gap through the design of a low-cost, easy-to-use, and effective EEG headset for engineering educational research studies.
