If you need EEG diagnostic testing, contact the office nearest you to schedule an appointment. Selim Benbadis, MD Division Director, Epilepsy, Eeg, & Sleep Medicine Professor, Department of Neurology Epilepsy, Eeg, & Sleep Medicine. Garza can determine if there are any abnormalities in your results after a careful review of the brain wave patterns indicated by the test. An EEG can occasionally lead to confusion, especially if non-specific. help localise the site of seizure activity in a child with focal epilepsy. Garza has completed a fellowship in Neurophysiology specializing in the reading and interpretation of EEGs. EEG is occasionally used to: help confirm or exclude epilepsy, following a thorough clinical evaluation (usually with EEG recording during episodes) monitor treatment in some types of epilepsy. Our office utilizes only certified EEG technicians to ensure a high quality diagnostic test. Once the test is complete, you can expect to go home and get back to your usual activities. Photic stimulation is also used which involves rhythmic flashing lights at various frequencies, to provoke seizure activity.ĭepending on the reason for your test, it can take up to 60 minutes to achieve the necessary results. You may be asked to breath quickly (hyperventilate) to help provoke seizure activity. When the electrical impulses move through the electrodes, you won’t feel any abnormal sensations or pain. Objective: To evaluate the prevalence of abnormal EEGs and related neurological disorders.
You should avoid eating or drinking for at least eight hours before your EEG.ĭuring the test, your provider attaches several electrodes on your scalp in different locations. Globally, EEG is used to further classify neuropsychiatric disorders. Your provider may advise you to stop certain medications in advance of your appointment. To ensure the most accurate results, avoid the use of any hair products on your test day. Common conditions an EEG can detect and monitor include:Īn EEG is a noninvasive, painless procedure that is safe for people of all ages. Voltage changes come from ionic current within and between some brain cells called neurons. EEG measures changes in the electrical activity that the brain produced.
Why do I need an EEG?Īn EEG is an effective diagnostic test for a variety of neurological conditions or disorders. EEG stands for electroencephalography which is an electrophysiological process to record the electrical activity of the brain. This is data can be reviewed to identify abnormal activity patterns. The electrodes are attached to wires that connect to a computer and capture electrical brain activity. These impulses are what your cells use to communicate with each other, influencing your movements and biological functions.Īn EEG monitors and records patterns of brain wave activity using electrodes attached to your scalp. An electroencephalogram (EEG) is a diagnostic test that can evaluate the electrical impulses occurring in your brain.
