Mobile EEG in epilepsy

Area of Science:

• Neurology
• Biomedical Engineering

Background:

• Routine electroencephalogram (EEG) sensitivity for detecting interictal epileptiform discharges in epilepsy is limited.
• Inpatient video-EEG monitoring is used to improve diagnostic yield but is resource-intensive.
• Home EEG recordings present a potential cost-effective alternative, though widespread adoption is lacking.

Purpose of the Study:

• To assess the current use and perceived value of home EEG recordings among Dutch neurologists.
• To evaluate a novel mobile EEG device (Mobita, TMSi) and compare its specifications with other devices.
• To gather patient perspectives on the usability and comfort of home EEG procedures.

Main Methods:

• Survey of 109 Dutch neurologists regarding home EEG adoption and utility.
• Evaluation of the Mobita mobile EEG device and comparison with three other commercial devices.
• Patient satisfaction survey regarding comfort and experience with home EEG.

Main Results:

• Thirty-three percent of surveyed neurologists reported using home EEG recordings.
• Neurologists see value in home EEG for investigating unclear paroxysms, not initial diagnosis post-seizure.
• Recent mobile EEG devices have addressed previous constraints like signal quality and recording duration.
• Most patients were satisfied with the home EEG procedure and device comfort, though public use caused unease.

Conclusions:

• Home EEG monitoring, particularly with improved mobile devices, holds significant potential for epilepsy diagnosis and management.
• Technological advancements are overcoming previous limitations, paving the way for broader clinical implementation.
• Patient acceptance of home EEG is generally positive, though social considerations for public use require attention.
