Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Age: 12 years and above
  • At least 2 years disease history
  • Refractory epilepsy:
  • Seizures are not completely responsive to longlasting antiepileptic treatment. At least 4 antiepileptic medicaments failed in mono or combined anticonvulsive regimen.
  • At least 4 seizures per week in the last month, despite adequate antiepileptic regimen.
  • Epilepsy surgery is not indicated or not accepted by the patient or by the parents of the patient.
  • A stable anticonvulsive regimen, defined as unchanged dose and type of the antiepileptic medication in the last month before tDCS and before VNS implantation.
  • Seizure diary is available and completed.
  • VNS implantation is planned within the next 2 months.

You may not qualify if:

  • Acute, symptomatic seizures (caused by tumor, stroke, acute encephalitis)
  • Uncontrolled medical problems (e.g. cardiovascular, nephrotic oder severe, chronic or severe acute disease)
  • Increased intracranial pressure for whatever reason
  • Implantation of metallic material (e.g. pacemaker, cochlear-implant)
  • Diseased or damaged skin over the scalp (e.g. Dermatitis)
  • Pregnancy
  • Known or supposed non-compliance
  • Age: less than 12 years
