How long does an eeg take
Q: Can my child eat/drink and take medications the day of the testing?Ī: Unless otherwise specified by the ordering provider, your child should do everything normally including taking any medications prior to and after the testing. From there, we will place the electrodes touching the scalp directly. We will move the hair out of the way to expose the scalp. Q: Will you have to shave my child’s head?Ī: No. During the testing, we are pulling the electrical pulses from your child’s brain and do not use any type of outside electrical stimulation. While the photic stimulation and hyperventilation may be uncomfortable for your child, we do not do anything during this testing to cause pain.

If you or your child is unable to wear a mask due to age or medical condition, please contact our office prior to your appointment so that we can make accommodations.Ī: This testing will not hurt. We do request that during this time, only one parent attend the testing appointments and we also request that masks be worn at all times, unless otherwise instructed by our EEG technician. Some patients can experience lightheadedness or tingling in the extremities during or immediately after hyperventilation, but these symptoms should go away by the time you leave the office.Īfter testing, your child will have paste in their hair that will wash out easily with warm water.ĭUE TO CONCERNS FOR COVID-19, we do use disposable materials during this testing and sanitize equipment thoroughly between patient appointments. We do use a pinwheel for hyperventilation for younger children to elicit quick breathing. We attempt hyperventilation for 2 minutes at the end of the study, followed by 3 minutes of post-hyperventilation where your child will relax and breathe normally. Hyperventilation: During the testing, your child might be asked to hyperventilate or breathe quickly. If your child is experiencing light sensitivity at the time of testing, they may close their eyes and this will not affect the study. We use the intermittent photic stimulation to detect abnormal epileptogenic sensitivity to flickering light. Photic Stimulation: Our test uses 8 rounds of flashing lights that get quicker with each round. This will be discussed with the doctor if appropriate. Some patients may require sleep-deprivation the night prior to testing. Rest: For about 20 minutes of the study, your child will be laying down with their eyes closed so they can go into a “sleep-like” state.

There are three parts to the testing itself based on the needs and age of the patient: We have a room with a small twin bed that we use for testing so that patients can relax comfortably during the testing. During the hookup, the scalp is cleaned and electrodes are placed on specific areas of the scalp with a water-soluble paste to measure the electrical activity for each area of the brain. The testing itself takes approximately 30 minutes. Our routine EEG process takes about one hour start to finish. This testing a non-invasive test that records electrical patterns in your brain and is used to help diagnose conditions such as seizures, epilepsy, head injuries, dizziness, headaches, brain tumors, and sleeping problems. Brain cells communicate with each other through electrical impulses that can be used to help detect potential problems associated with the brain’s electrical activity. An EEG (electroencephalogram) is a test used to evaluate the electrical activity in the brain.
