Symptoms and clinical questions an EEG may help investigate.
Why May an EEG Be Requested?
A straightforward recording process.
Electrode positions are measured
Measurements will be taken to identify electrode positions.
Electrodes are attached
Small electrodes are attached to the scalp using conductive paste or adhesive.
Brain activity is recorded
The patient relaxes while brain activity is recorded.
Simple instructions may be given
The patient will be asked to open and close their eyes.
Additional activation may be used
Deep breathing and flashing lights will be used when clinically appropriate.
Electrodes are removed
The electrodes are removed after the recording.
The test is generally painless, although the paste may leave the hair feeling sticky.
