NCT02946151

Brief Summary

The study is a two-phase study, which aims to explore the uses of a novel electrode type in detecting epileptic seizures. The electrode is designed for subcutaneous implantation with long-term monitoring in mind.

Outcome Measures

Primary Outcomes (3)

  • Seizure comparison

    Qualitative comparison of patient-recorded seizures and EEGgraphical seizures

    24 months

  • Adverse events

    Descriptive account of device related adverse events

    24 months

  • Compliance

    Descriptive account of compliance in use of the investigational device

Study Arms (1)

Implantation

EXPERIMENTAL

Implantation of a subcutaneous electrode and connection to the external logging device

Device: UNEEG implantable EEG electrode and data storage device

Interventions

The implantable EEG electrode will be implanted subcutaneously in the relevant temporal region by a certified neurosurgeon. The EEGgraphical data recorded will be transmitted transcutaneously to the data storage device via an inductive link, providing continuous data on brain activity.

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Semiology of some seizures compatible with mesial temporal lobe involvement.
  • Paraclinical findings supporting mesial temporal seizure focus. Such proof may consist of:
  • previous EEG recording interpreted as compatible with mesial temporal involvement OR
  • radiological findings demonstrating pathology in the mesial temporal area (CT, MRI, FDG-PET or SPECT).
  • Age 18-90.
  • Current seizure frequency (fulfilling criteria 1) of more than one per week to be eligible to EMU admission or 1 per month for direct enrollment to home monitoring (by own account).
  • Available for the duration of the study (6 months from screening).

You may not qualify if:

  • Known disorder of hemostasis.
  • Daily or frequent (more than 2 days per week) treatment with any drugs of the following types:
  • antiplatelets
  • anticoagulants
  • chemotherapeutics
  • non-steroid anti-inflammatory drugs (NSAID)
  • omega 3 fatty acids (fish oil)
  • Skeletal deformities or damage at the proposed implantation site to an extent that impedes correct electrode placement.
  • Scheduled facial or cranial surgery within 6 months from enrollment.
  • Active deep brain stimulation device.
  • Presence of implanted ICD pacemaker, cochlear implant or other active implants.
  • Planned transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) in the duration of the study.
  • Presence of any implanted device at the proposed site of implantation.
  • Known allergy towards any material that is part of the investigational device.
  • Females of childbearing potential who are pregnant, intend to become pregnant, or are not using adequate contraceptive methods throughout the study.
  • +30 more criteria
