  • ICTALS2019 the Epilepsy Journey
    ICTALS2019 The Epilepsy Journey 2-5 September In partnership with Abstract book This conference is supported by a grant from the American Epilepsy Society ICTALS2019 The Epilepsy Journey Foreword The International Conference for Technology and Analysis of Seizures, 2019 (ICTALS2019) aims to bring together neurologists, neuroscientists, researchers from quantitative disciplines and people with lived experience of epilepsy in order to work as a community to advance our understanding of epilepsy and develop practical ways to improve diagnosis and treatment. The theme for this year’s conference is: The Epilepsy Journey: from first seizure to treatment and beyond. We will emphasise how advances in our understanding of the dynamics of brain networks can be used to make a difference to people with epilepsy at all points of their journey: from elucidating the causes of the first seizure to diagnosing epilepsy, understanding how ictogenic networks give rise to recurrent seizures and how this insight can inform personalised treatment. To encourage this focus on the whole epilepsy journey we seek to include all relevant communities. In addition to discussions on current scientific, clinical and technological advances, we will take steps to increase accessibility for people with lived experience of epilepsy. Dates: Monday 2 September 2019 - Thursday 5 September 2019 Venue: University of Exeter, Streatham Campus, Xfi Building Conference website: http://ex.ac.uk/ictals2019 Contact the organisers: [email protected] ICTALS2019 The Epilepsy Journey Partners We are partnering with charities Epilepsy Research UK and Epilepsy Action and Alliance for Epilepsy Research. Sponsors This event would not be possible without the generous contributions from our generous sponsors UCB, the Epilepsy Foundation, NeuraLynx, and Liva Nova.

We have published 110 peer-reviewed items of primary research and a further 54 chapters in books, reviews and commentaries of expert opinion. During this period, Young Epilepsy Chief Executive Carol Long caught the research bug and moved on to begin her PhD at Durham University.

However its current use is restricted to specific electroencephalograph scenarios, namely in the diagnosis refractory focal epilepsies where electroencephalography (EEG) has been source localisation inconclusive. This review highlights the recent progress of MEG within epilepsy, including advances in the OPMs technique itself such as simultaneous EEG/MEG and intracranial EEG/MEG recording and room temperature MEG recording using optically pumped magnetometers, as well as improved post processing of the data during interictal and ictal activity for accurate source localisation of the epileptogenic focus. These advances should broaden the scope of MEG as an important part of epilepsy diagnostics in the future. 1. Introduction one large study of 1000 consecutive cases of refractory focal epilepsy demonstrated that MEG provided additional information to existing pre- A mainstay in epilepsy diagnostics over the last century has been the surgical methods (including scalp EEG, single photon emission electroencephalogram or EEG. Simply explained, EEG records electrical computed tomography (SPECT) and MRI) in 32% of cases, and complete currents reflecting synchronous neuronal activity attributable to the magnetoencephalography resection was associated with significantly brain surface, and can identify abnormal activity related to epilepsy with higher chances to achieve seizure freedom in the short and long-term good temporal resolution.

The integration of new wearable and mobile technologies to collect electroencephalographic (EEG) and extracerebral signals in a portable system might be the solution to prospectively identify times of seizure occurrence or propensity. The performances of several seizure detection devices have been assessed by validated studies, and patient perspectives on wearables have been explored to better match their needs. Despite this, there is a major gap in the literature on long-term, real-life acceptability and performance of mobile technology essential to managing chronic disorders such as epilepsy. Objective: EEG@HOME is an observational, nonrandomized, noninterventional study that aims to develop a new feasible procedure that allows people with epilepsy to independently, continuously, and safely acquire noninvasive variables at home.
