How to understand eeg results

An EEG, or electroencephalogram, is a test that records the electrical signals of the brain by using small metal discs (called electrodes) that are attached to your scalp. Your brain cells communicate with each other using electrical impulses. They’re always working, even if you’re asleep.

How are EEG scans performed?

EEG scans are performed by placing EEG sensors, which are small metal discs also called EEG electrodes, on your scalp. EEG electrodes pick up on and record the electrical activity in your brain. The collected EEG signals are amplified and digitized then sent to a computer or mobile device for storage and data processing.

How does an EEG diagnose epilepsy?

This activity shows up as wavy lines on an EEG recording. An EEG is one of the main diagnostic tests for epilepsy. An EEG can also play a role in diagnosing other brain disorders. An EEG can determine changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder.

What should I expect with an EEG?

There are no risks associated with an EEG. The test is painless and safe. Some EEGs do not include lights or other stimuli. If an EEG does not produce any abnormalities, stimuli such as strobe lights, or rapid breathing may be added to help induce any abnormalities.

What is an EEG and how it works?

How does an electroencephalogram test (EEG) work? Your brain cells create electrical signals that are picked up by the electrodes and sent to a computer. The computer shows the results on screen and also stores the information for evaluation. SOURCE: National Migraine Association. SOURCE: National Migraine Association.

What do they do to you during an EEG?

Here are some things you can expect to happen during an EEG:

  • A technician measures your head and marks your scalp with a special pencil to indicate where to attach the electrodes.
  • A technician attaches discs (electrodes) to your scalp using a special adhesive. Sometimes, an elastic cap fitted with…
  • You relax in a comfortable position with your eyes closed during the…

What to expect during an EEG?

An electroencephalogram (EEG) is a diagnostic test doctors use to record and analyze brain waves. During an EEG scan, you can typically expect to relax comfortably, as the test is painless.
