The EEG Lab also performs evoked potential tests and intracranial corticography. Last year, our team performed approximately 5,000 outpatient EEG studies, 1,000 ambulatory EEG studies, 1,500 days of monitoring in the Epilepsy Monitoring Unit (EMU), and 2,000 days of monitoring in CHOP’s intensive care units. The EEG Lab at Children's Hospital of Philadelphia (CHOP) supports neurology patients at CHOP's Main Campus, numerous satellite locations, and additional regional hospitals. Why would a child need an EEG?ĮEG testing is primarily used to diagnose and manage epilepsy, but it may also be used to diagnose other brain disorders or evaluate events of unclear cause. An EEG measures brain waves through small metal disks called electrodes that are gently pasted to your child's scalp right before the test and then removed once the EEG is complete. Be sure to speak up if there’s anything about your results that you don’t understand.An electroencephalogram (EEG) is a test that measures the electrical activity in the brain, called brain waves. Before you review the results, it may be helpful to write down any questions you might want to ask. It’s very important to discuss your test results with your doctor.
Hyperventilation is also commonly induced during an EEG to produce abnormalities.
The technician performing the EEG is trained to safely manage any situation that might occur. When someone has epilepsy or another seizure disorder, there’s a small risk that the stimuli presented during the test (such as a flashing light) may cause a seizure. If an EEG does not produce any abnormalities, stimuli such as strobe lights, or rapid breathing may be added to help induce any abnormalities.
