This book offers a detailed account of all aspects of photosensitive epilepsy, including genetic testing, functional imaging (fMRI, MEG), pharmacological studies, animal studies, classification based on the occurrence of photoparoxysmal responses (PPRs) in different epilepsy syndromes, and the available prevention and treatment options. In addition, the comorbidity of and overlap between migraine and epilepsy are discussed. Informative case histories with EEG examples and a helpful glossary are included.
In epilepsy, the term photosensitivity is used both for epileptic seizures triggered by flashing or flickering light and for epileptiform discharges evoked by intermittent photic stimulation (IPS) during an EEG recording. Most patients with a clear history of visually induced seizures will show epileptiform EEG discharges during IPS (PPRs). As epileptiform discharges can be evoked in photosensitive patients at any time, without triggering seizures, theycan be considered a useful surrogate marker of the necessity and efficacy of epilepsy treatment. This book will serve as an ideal guide to the subject for pediatricians, (pediatric) neurologists, epileptologists, (child) psychiatrists, clinical geneticists, neuropsychologists, neuropharmacologists, occupational therapists, and basic scientists.

About the author
Dorothée Kasteleijn-Nolst Trenité, MD, PhD, works in the Department of Medical Genetics, University Medical Center Utrecht, the Netherlands and the Child Neurology Division, Department of Pediatrics, Sapienza University of Rome, Italy. Her work in Utrecht aims to help unravel epilepsy genetics, while in Rome she was given a Marie Curie Chair position within the FP6 EU research program. Dr. Kasteleijn trained extensively in epilepsy at the Epilepsy Centre “Meer en Bosch- de Cruquiushoeve” (now known as SEIN) and in video-EEG and the combination of pharmacology and EEG studies. Dr. Kasteleijn has practiced both child and adult neurology. She has done research on various topics in epilepsy (driving, neuropsychology, and neuropharmacology), but above all has been known for her work on photosensitivity since the publication of her thesis on this topic in 1989. She enjoys international collaboration and has (co-)organized many workshops, founded a European Consortium on Photosensitivity Genetics, and stimulated the development of EU guidelines. She is the author of very many peer-reviewed articles and book chapters and is regularly invited as a keynote speaker all over the world. She is an editor and reviewer for many journals in the field of Neurology. She has had many international PhD and Master’s students. One of her most consistent activities besides lecturing and publishing is raising awareness at the international level of the patient with epilepsy in general and photosensitive epilepsy in particular.
