Epilepsy affects 0.7% of the general population and 15-20% of patients develop drug resistance. The temporal lobe epilepsy (TLE) is the most common symptomatic focal epilepsies with a particularly high rate of drug (about 20 to 30%). In this type of epilepsy, where feasible, surgical removal of the home is the best therapeutic outcome.

Mechanisms of epileptogenesis and drug resistance are still mysterious. Of recent clinical and experimental studies have shown that dysfunction of the blood-brain barrier (BBB) contributes to epileptogenesis and drug resistance. It is now recognized that cytokines exacerbate the excitability and permeability of the BBB, which was recently confirmed by studies showing that treatment of inflammation reduces epileptogenesis. Moreover, we have described an association between pathological angiogenesis and BBB permeability in the tissue of patients with excision of drug-resistant TLE. With experimental models, it was revealed an activation of the VEGF-VEGFR2 by seizures leading to rapid degradation of the BBB.

The investigators hypothesis is that the identification of factors involved in BBB permeability may designate potential targets for drug-resistant partial epilepsy.

Primary Outcome Measures:
  • Comparison of Biomarkers [ Time Frame: 12 months after inclusion (day 0) ]
    Identify blood sampling biomarkers of drug resistance in temporal lobe epilepsy, an analysis by large-scale expression profiling of serum factors involved in inflammation, immunity and angiogenesis

Secondary Outcome Measures:
  • permeability of the blood-brain barrier [ Time Frame: Day 0 ]
    Compare changes in lesion morphologic imaging and blood flow measurements by Magnetic Resonance Imaging between the two groups
