  Purpose

The primary objective is to demonstrate that a higher proportion of responders to deep brain stimulation (DBS) in the anterior nucleus (AN) of the thalamus in refractory epilepsy patients in the SANTE study exhibit a recruitment rhythm relative to non-responders.


Condition Intervention

Primary Outcome Measures:
  • To demonstrate that a higher proportion of DBS responders exhibit a RR relative to non-responders, using maximum tolerated voltage settings, at activated electrode contacts used for DBS stimulation in the SANTE study. [ Time Frame: Study testing to occur during the long-term follow-up phase of the SANTE trial. ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • For patients without a RR at their activated DBS electrode contacts used in the SANTE study, demonstrate that activating other electrode contacts generates a RR. [ Time Frame: Study testing to occur during the long-term follow-up phase of the SANTE trial. ] [ Designated as safety issue: Yes ]

Groups/Cohorts Assigned Interventions
Responder
A subject having at least a 50% reduction in total seizure frequency compared to the SANTE study 3-month Baseline Phase
Device: There was no intervention.
There was no intervention. This study was designed as an in-clinic testing protocol to identify recruitment rhythms.
Non-responder
A subject with a less than 50% reduction in total seizure frequency compared to the SANTE study 3-month Baseline Phase.
Device: There was no intervention.
There was no intervention. This study was designed as an in-clinic testing protocol to identify recruitment rhythms.
