Electroencephalogram - EEG
- is a technique which registers the brain’s electrical activity.
- it is similar to an electrocardiogram (ECG) which is often performed as part of a routine heart exam, but looks at the head instead.
EEG is not a new technique:
- It has been used for many years as part of a routine neurological and psychiatric examination.
- With the advent of new technologies such as CAT scans and magnetic resonance imaging (MRI), EEG became less important, except in the diagnosis of epilepsy.
The EEG is reborn!
- Due to developments in computer technology over the last few years, EEG can now suggest connections between changes in the brain’s electrical activity and certain diseases.
- In patients who are confused, disorientated or have other memory problems, EEG is a fast way to differentiate between degenerative diseases (dementia) or other factors.
- It is also used to determine the effect of medication or distinguish between metabolic diseases, infections and intoxication. EEG is an important diagnostic tool.
