Eligibility Criteria

Inclusion

  • Children enrolled in this study must:
  • Be 5-14 years of age at consent.
  • Have a diagnosis of LGS, as determined by:
  • Slow (\<3.0Hz) spike-and-wave pattern and/or fast wave pattern (tonic seizures) detected on EEG at least six-months prior to the enrolment into the baseline period
  • History of drop seizures (tonic, atonic, or tonic-clonic) that precedes at least six-months prior to the enrolment into the baseline period
  • Have experienced at least 10 seizures in the four weeks prior to enrolment.
  • Have tried and not responded to two or more antiseizure medications prior to enrolment.
  • Be taking one or more anti-seizure medication(s) at a stable dose for at least the four weeks prior to enrolment.
  • Have a carer who is willing for their child's maintenance anti-seizure medications and ketogenic diet (if relevant) to be unaltered for the trial duration.

  • Children enrolled in this study must not:
  • Have received prior deep brain stimulation insertion.
  • Have an active ('on') vagus nerve stimulator (or active within the six months prior to the baseline period).
  • Have had a change in their anti-seizure medication prescription or stopped their ketogenic diet within the last 4 weeks
  • Have started or made changes to the prescription of a ketogenic diet within the last 12-weeks
  • Have abnormal thalamic anatomy detected on imaging that would render DBS either unsafe or unfeasible.
  • Have a bleeding disorder(s).
  • Have a medical condition(s)/factor(s) that would increase their anaesthetic risk to an unacceptable level.
  • Have a nickel allergy.
