Description

Inclusion Criteria:

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

Exclusion Criteria:

  • Body Mass Index > 28 kg/m2

  • 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).

  • The use of the following medication is an exclusion criterium;

    • ß-blockers,
    • Ketogenic diet
