The aim of this study is to analyse thanks to eye tracking experiments ocular movement classical parameters in children with attention deficit hyperactivity (ADH) and to compare them to results obtained in healthy children and to results obtained with neuropsychological tests commonly used in standard health care.

We should then be able to compare eye tracking with neuropsychological parameters.

The final objective is to give to health professional a tool for ADH investigation with which they should be able to do a simple and effective follow up of children with ADH.
