Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Postoperative patients treated with vagus nerve stimulation for refractory epilepsy

You may qualify if:

  • Subjects treated with VNS for epilepsy, aged 18-65 years, with a Body Mass Index (BMI) ≤ 28 kg/m2.

You may not qualify if:

  • Body Mass Index \> 28 kg/m2
  • Daily epileptic insults.
  • Subjects that need 'Rapid Cycling' VNS to control their frequency of epileptic insults.
  • Psychological unstable subjects (as judged by the treating neurologist).
  • subjects with mental retardation (as judged by the treating neurologist).
  • subjects with severe behaviour disorders (as judged by the treating neurologist).
  • Pregnant subjects.
  • Subjects that previously underwent high dose radiation for diagnostic or therapeutic purposes (radiotherapy, high frequency CT-scans).
  • ß-blockers,
  • Ketogenic diet
