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.
AMBULATORY EEG 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.

Nerve Conduction Velocity/EMG-Bilateral.Routine/Ambulatory (24, 48 and 72 hour) EEG.Dasa Satyam (INTERVENTIONAL PAIN MANAGEMENT) Arrange to come in each day during testing (if your test lasts for more than one day).This will make it easier to change clothes when you get home. Wear a shirt that zips or buttons in front.Bring a cap or scarf to cover your head when you leave (if you wish).Remove hairpieces or unbraid hair before the test.Plan to be in the office for up to two hours.At the end of the test, electrodes will be removed and the paste wiped off. It is very important to write the date, time and a brief description of unusual events or symptoms. You will receive a log to write down anything unusual that occurs during the test. The test begins as soon as you leave and lasts until the disks are removed. You will receive instructions about what you should and should not do during the test. You may wear a cap or a scarf over this to cover it up. The technologist will wrap gauze around your head to cover the wires and disks. Wear the pack around your waist or over your shoulder. This weighs about three pounds and is carried in a pack. Wires connect the disks with a small computer that you will take home. During an ambulatory EEG, the technologist will put small metal disks on your scalp, held in place by adhesive. Ambulatory EEGĪn ambulatory EEG may take one to four days, depending on how much information your physician needs. At the end of the test, the electrodes will be removed and the paste wiped off.Ī routine EEG lasts about 60 to 90 minutes. The technologist may ask you to take deep breaths and show you flashing lights. This makes sure that the machine only picks up brain waves and not other movement. When the test starts, you will need to keep very still and keep your eyes closed. Small metal disks (electrodes) will be placed on your head using a creamy paste to keep them in place. The technologist will ask about your medical history, measure your head and clean your scalp. Routine EEGĭuring a routine EEG, you can lie down on a comfortable bed. A routine EEG typically lasts 60 to 90 minutes an ambulatory EEG can last up to four days depending on how much information your physician needs. The EEG can also show where in the brain these changes occur. Brain activity may change with certain conditions or after an injury. An EEG is a test that records brain activity. It can also help in planning your treatment. The EEG helps your physician diagnose your condition.
