About this trial

This is an interventional treatment trial for Partial Epilepsy focused on measuring Deep Brain Stimulation, Anterior Nucleus of thalamus, Treatment refractory, Pharmacoresistant partial epilepsy, vagus nerve stimulation therapy

Eligibility Criteria

16 Years - 60 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patient with focal or multifocal epilepsy with or without secondary generalized seizure inoperable at the time of inclusion
  • Failure of pharmacological therapies (pharmacoresistant epilepsy) for over 4 years (persistent seizures despite at least two anti-epileptic treatments used at the optimal dose for at least 2 years)
  • Failure of vagus nerve stimulation, defined as the persistence of crises considered debilitating after 2 years of VNS's treatment
  • VNS failure in a patient treated with VNS, for less than 2 years. with stop early due to the worsening crisis
  • Intelligence quotient above 55
  • Have the written consent of the legal representative for patients under guardianship and minors
  • Affiliation to the french social security system or equivalent
  • People who signed the consent form
  • Seizure frequency at least 4 crisis / month on average for at least 3 months, about 12 crisis in 3 months objectified by the neurologist during visit pre-inclusion, and confirmed by the neurologist after 3 months of Baseline during the inclusion visit

Exclusion Criteria:

  • Patient with a generalized epilepsy Immediately
  • Patient with a simple partial seizures (subjective manifestations only)
  • Patient with a cons-indication for MRI, a serious intercurrent disease, a progressive brain tumor

  • Woman of childbearing potential without effective contraception, or pregnant or lactating
  • People hospitalized without consent
  • People deprived of freedom

5. Study Description

Brief Summary
The main objective of the study is twofold: Assess the clinical efficacy of DBS on epilepsy according to their number and severity at 1 year follow up. Perform a cost-effectiveness analysis from the perspective of Medicare at 1 and 2 years. The study hypothesis is that thalamic DBS (neurostimulation of the anterior nucleus of the thalamus) will decrease significantly, the frequency (potentially 50% reduction in severe crises) of the most severe seizures, in at least 50% of patients who have drug-resistant partial epilepsy; and should also improve significantly the quality of life through a gain of independence in activities of daily life, the possible recovery of functional abilities, recovery of social or professional activities.
