Epilog is founded on passion for EEG technology deeply rooted in academical research. We are convinced that by using advanced signal analysis techniques EEG can be exploited to its fullest potential and become the window into the brain it has always aspired to be. Enabling advanced EEG processing and making it accessible to clinical practice is Epilog’s driving force. As a team of experts we have the expertise and experience to bridge the gap between engineering and medicine.

Bringing advanced EEG technology into clinical practice is a complex challenge. Several advanced signal and image processing techniques have been studied and validated in epilepsy. Unfortunately, despite very promising results of validation studies, they have not been widely disseminated in clinical practice. We believe this is due to the technological barriers that exist for clinical centers who do not have resources that can be dedicated to this task. With Epilog we aim to change this to the benefit of the clinician and the patient.


The core philosophy of Epilog is to bring advanced EEG diagnostic technology to clinical practice as a service. A service that allows EEG readers to focus on what really matters: the interpretation of the data to the benefit of the patient or the study.

We offer interpretation guidelines, training and symposia to continuously involve and train our collaborating centers, clinicians and industry.


Our services are focused on epilepsy. We offer 3 different solutions. Epilog PreOp that just recently became Persyst ESI supported by Epilog provides an efficient analysis of long-term EEG recordings and HD-EEG recordings in the preoperative work-up, including electrical source imaging for the localization of the irritative zone. Epilog DX is focused on making the analysis of 24 hours or overnight EEG recordings more approachable and less time consuming. Our services for industry are dedicated to clinical trials, offering our EEG derived paramaters to de-risk them. For academia we offer our research services that our tailor made to the needs of the study.



Focus on the interpretation of your data instead of learning how to use technical software.


Our services are completely hardware independent. Do not worry about compatibility issues.
