When it comes to detecting abnormalities in the electrical activity of the brain, the electroencephalogram or EEG is the diagnostic procedure that is widely used. An EEG tracks and records electrical brain wave patterns, making it easier for physicians to spot abnormal patterns that indicate seizures and other problems.
When is Electroencephalogram (EEG) Needed?
An electroencephalogram may be needed when it’s necessary to distinguish if a person has a mental health problem or a physical one (problems in the nervous system or brain). EEG is also needed when doctors need to diagnose and monitor seizure disorders as well as identify causes of other problems such as narcolepsy. In most cases, doctors perform EEG tests to confirm an individual’s diagnosis of epilepsy and also see what types of seizures are occurring and what parts of the brain are involved (see Epilepsy and Seizure Animation).
The Electroencephalogram (EEG) Procedure
The standard procedure is to place small metal discs with electrodes on the patient’s scalp. The discs will then be activated and signals will be sent to a computer to record the results. If normal electrical activity is present in the brain, the results show a characteristic pattern. If cortical abnormalities are present, we can distinguish the type of abnormality as well as the area(s) where the abnormality occurs.
