What to Know About Your Study

1. Preparing for a Study

  • Hair must be free of hair spray, oil, and gels.
  • Remove any and all hair extensions, glue and clips.  Undo braided hair, remove wigs and hair pieces.
  • Please wash your hair within 24 hours of the appointment.
  • Wear a button-up, zippered shirt, or a wide neck shirt so you are able to change your shirt without disturbing the EEG recording.
  • Do not get the equipment wet while wearing it (no showers or baths during the study).
  • Do not scratch your head.
  • Do not run, jump, wrestle or participate in any extreme physical activity.
  • Do not participate in any activity that will cause excessive sweating.
  • Do not chew gum (constant chewing doesn’t allow for proper recording).
  • Do not place electrical devices (headphones, electric blanket, etc.) on the electrodes.
  • Patient may use a telephone, but keep the phone on the ear, do not lean the phone on the side of your head.

2. During the Study


  • A set-up technician will call thirty minutes prior to your scheduled appointment.
  • The technician measures your head and marks your scalp with a crayon to map out where 25 flat metal electrodes on your scalp will be temporarily secured using collodian, a gentle adhesive glue made for skin.
  • Connecting the electrodes to your scalp is painless. You will not lose any hair from the attachment of the electrodes.
  • The EEG electrodes attach to leads (wires) that connect to a recorder called the Track-IT device, which collects the electrical activity in your brain.
  • You will be wearing the Track-IT inside of a small bag over your shoulder or cross-body over your chest.
  • The video camera will be mounted on a lightweight tripod with an acquisition laptop and microphone attached.
  • The technician will set up equipment in the room you will be in most often and run a 10 minute baseline study.
  • Your study set-up appointment takes approximately 2-3 hours in order to complete all lead placement, review of testing instructions and equipment.
  • Throughout the duration of your in-home EEG, a monitoring technician will remotely log into the study three times a day (at a minimum) to ensure that all electrodes are working and recording properly.
  • You will be asked to keep a diary of your activities such as sleeping, eating, and any seizures/events that occur (A family member may record these events if necessary).
  • Avoid scratching. If you have an itch, gently tap or pat the itchy electrode. Scratching will loosen the connection and affect the quality of the test.
  • If an electrode becomes disconnected, your set-up technician will be dispatched to your home to resolve the issue.
  • You will be asked to periodically check on the laptop screen. You should see a clear picture centered in the pop-up screen.  You should also notice that the frame numbers are increasing/advancing. If you do not see these numbers increasing, please contact your local technician immediately.
  • If at any time you notice a black screen, a white screen, one STOP sign (versus two STOP signs) or a PLAY button, please contact your technician immediately.

What to Do During a Seizure/Event

  • Press the Track-IT button for any seizure/event. Tap the Track-IT button once. You or a family member can do this
  • Talk out loud or into the microphone describing any symptoms or events you are experiencing. You or a family member can do this.

3. After the Study

  • At the end of the EEG study, a technician will return to your home to gently remove the electrodes and collect the recording equipment.
  • It is common for your hair to still have paste and glue remnants from the electrodes. The best home remedies to remove the paste/glue are:
    • Pure acetone (nail polish remover)
    • Baby oil
    • Hair conditioner applied to dry hair
    • Washing your hair in the shower 2-3 times with a brush/comb
  • The disconnect appointment takes approximately 30 minutes - 1 hour

4. Results of the Study

  • After your study is completed, your doctor will then review and discuss it with you at your next visit.
  • Do not ask your technician about results, as they are unable to interpret or explain results. Only your physician can discuss your study with you.
