What is Electroencephalogram (EEG)?
Electroencephalogram (EEG) is a diagnostic test used to find problems related to the electrical activity of the brain. An EEG tracks and records brain wave patterns by using small metal discs, called electrodes, that are attached to your scalp. The electrodes send signals to a computer to record the results. Normal electrical activity in the brain makes a recognizable pattern. Through an EEG, doctors can look for abnormal patterns that indicate seizures and other problems.
Who needs an Electroencephalogram (EEG)?
An EEG is used to evaluate several types of brain disorders. Most EEGs are done to diagnose and monitor seizure disorders. EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior, and may also be used to determine the overall electrical activity of the brain.
