Dr. Frans S.S. Leijten (1960) studied medicine at Utrecht University and obtained his MD in 1986. He became a neurologist and clinical neurophysiologist in 1994. In 1996 he defended his PhD thesis on critical illness polyneuropathy at Leiden University. He worked as an epileptologist at epilepsy center SEIN, then called Meer en Bosch, in Heemstede, from 1994-1996. Since then, he has been working at the University Medical Center Utrecht, where he is now head of the EEG department and the monitoring unit for invasive EEG recordings. He is also chairman of the National Dutch Epilepsy Surgery Taskforce. He is a member of the European Childhood Epilepsy Surgery Group U-TASK and of the European Network for Epilepsy Research ENER. He is a member of the Consilium Neurologicum, responsible for the education of neurology residents in the Netherlands. He has received various educational awards and is a well-known speaker at congresses.

Research line

His research focuses on intractable focal epilepsy and epilepsy surgery. His team explored the clinical use of new advanced neuroimaging methods, clinical decision-making in focal epilepsy, quality-of-life and coping issues in intractable epilepsy, and new treatments. He is engaged in a national collaboration which led to the develop a device to detect seizures during the night (Nightwatch). Recent research focuses on networks in the intracranial EEG measured on the cortex. Together with the department of Applied Mathematics of Twente University, he is engaged in developing a neural mass computer model that can represent the epileptic cortex of individual patients. For a demonstration tool, look at .

Using epileptic network knowledge, he has started a clinical trial of closed loop cortical stimulation in patients with intractable epilepsy in the primary sensorimotor cortex. Dr Leijten has over 150 publications in peer-review journals and is the editor of a Dutch textbook on clinical epilepsy.

Side Activities

(1) I am chair of the TeleEpilepsy consortium that has developed a medical device to detect nocturnal motor seizures, NightWatch, together with a commercial partner, LivAssured. There are no direct financial ties, but a percentage of future profit from the sales of NightWatch will be made available to the consortium for further research in epilepsy.

(2)  I am a consultant of and hold shares in ProLira, a start-up company that developed DeltaScan, a device to detect delirium making use of EEG technology.
