This study will included 20 children presenting with epilepsy with spasms. It aims to offer
these children, non invasively and without supplementary examinations, a recording of local
and cerebral hemodynamic changes concomitant with an electroencephalographic recording during
epileptic episodes. This will be carried out by combining optical imaging using near
infra-red spectroscopy (NIRS) with electroencephalography (EEG), in a simultaneous
high-resolution (HR) recording.
This study is among those based on multimodal analyses of epilepsy, combining methods of
analysis of electrical activity (electrical imaging) and hemodynamics (optical imaging).
Surface electroencephalography (EEG) is a precious tool enabling the study of neuronal
dysfunction from a functional point view. It is used in the routine follow-up of children
with epilepsy. Optical imaging is a promising medical imaging technique. It uses light in the
spectral regions of near infra-red as a source of radiation. It is quantitative, rapid, non
invasive, and inoffensive which could easily be used at the child's bedside or in a clinical
setting and can provide metabolic information about cerebral function.
This study is multidisciplinary, which calls upon the skills of neurophysiologists,
biophysicists, and clinicians
