These include brain tumors, epilepsy, sleep disorders, dementia, and more. Do I Need an EEG?ĮEGs can be used to diagnose a variety of conditions and disorders that might be taking place in your brain. Usually, this procedure lasts for either 24, 48, or 72 hours.Īmbulatory EEGs are particularly helpful when patients cannot identify their own seizures (people with mental retardation, encephalopathy, and other similar conditions are often unaware of their seizures), or during nocturnal hours when the patient is asleep. However, instead of attaching to a larger machine, the wires attach to a smaller device (closer to the size of a brick), which the patient can wear around without interfering with normal everyday activity. Similar to a Routine EEG, Ambulatory EEG attaches wires to the patient’s scalp to measure their electrical brainwaves. These procedures can confirm or dismiss whether epilepsy waves are causing the patient’s seizures. Most commonly, Ambulatory EEGs are used when a doctor is looking to monitor activity when a seizure is occurring. Depending on the patient, an elastic cap might also be placed on his or her head. These discs are coated with a sticky adhesive to keep them in place. A technician will measure and mark the head of the patient before applying metal discs all over your scalp.
#WHAT DOES EEG MEASURE FREE#
The EEG procedure itself usually takes about 60 minutes and patients are free of pain or discomfort. These brainwave observations can diagnose a variety of conditions ranging from seizures to comas to epilepsy. Routine EEG About Routine EEGsĪn Electroencephalography, commonly known as an EEG, is the measuring and detection of electrical brainwaves. Ambulatory EEGs are longer term measurements of your brain, and can be done at home or in a hospital depending on the discretion of your doctor. However, Routine EEGs usually only last up to a maximum of 60 minutes, which can be insufficient for detecting certain conditions. Routine EEGs are used to detect a variety of brain-associated disorders and conditions.
