A two-stage stratification method will be used to ensure sufficient number of AEDs resistant patients to be enrolled:
a) stratification of the investigators: there are a total number of about 2,000 neurologists in each country of interest. These neurologists can be divided in 3 categories according to the magnitude of their activity in the management of epilepsy : - A first category concerns neurologists with a low activity (less than 5 outpatients a week in consultation) they will not be invited to participate. - A second category concerns neurologists specialised in epilepsy management (epileptologists) who will be identified, either as members of a medical association (French League Against Epilepsy in France) or through their setting in centres specialized in epilepsy (about 20 centres in France and Spain). All epileptologists in this category will be asked to participate. - The third category includes the remaining neurologists. The study will be proposed to a random sample of this last group up to reach the expected number of participating investigators. b) stratification of the patients included: each investigator will be asked to enroll about one AEDs resistant in three patients, the other patients being either patients whose AEDs resistance is currently undefined or AEDs responsive patients. The 3 sub-groups of patients included will therefore be as follows: • AEDs resistant patients in accordance with the criteria established by the ILAE in 2009 (see the note below); • AEDs responsive patient at inclusion; • Status currently undefined regarding AEDs resistance at inclusion According to the 2009 ILAE Task Force definition a AEDs resistance is defined as “failure of adequate trials of two tolerated appropriately chosen and used AEDs schedules (whether as monotherapies or in combination) to achieve sustained seizure freedom”. The seizure freedom is defined by “freedom from all types of seizures for 12 months or 3 times the preintervention interseizure interval, whichever is longer” |
Database objective | |
Main objective | To describe the population of adult patients with focal epilepsy currently being treated by an association of at least two antiepileptic medications, in terms of clinical profile, current medical management and seizure control, history of care, referral pathways and quality of life. |
Inclusion criteria |
• Patient aged ≥ 18 years, presenting with focal epilepsy with or without secondary generalization;
• Patient currently treated with at least 2 antiepileptic medications in association, for at least 3 months, whether the patient is seizure-free or not; • Available medical data allowing to specify AEDs responsiveness status (resistant, responsive, or undefined); • Patient who has agreed to participate after having read the information letter. |

Data collection method | The data collected will circulate from the investigators to the data management center via a depersonalized paper questionnaire (medical data). The other data collected will circulate from the patients to the data management center via the depersonalized paper questionnaires (self-questionnaires) sent through the mail (return postage paid envelope). |
