What does an EEG test involve?

For an EEG investigation itself, your appointment will be led by a specialist clinical physiologist who will walk you through the entire process. It will likely entail the following:

  • Brief preparation involving the application of sticky removable discs onto your head to record brain activity.
  • Brain activity recording for 20-60 mins dependent on study specifics
  • After the study, said discs would be removed you could resume your usual day to day activities.

For an overnight study (eg. home video telemetry or sleep study), it would be similar to the above but once the discs are fitted, you’d be sent home or to a hotel overnight for monitoring in your sleep. You’d then return the following morning to meet a clinical physiologist again who would remove this kit and save any data for onward reporting.

What are the benefits of having an EEG?

Having an EEG will give  your consultant essential clinical information to support or rule out diagnosis of specific brain conditions. Depending on the results reported, your clinician will advise on any follow-up tests needed and next steps.
