In the diagnosis of epileptic conditions, dementia, and sleep disorders, electroencephalography (EEG) can be used to investigate electrical activity in the brain. For this form of examination, electrodes are attached to the scalp to record fluctuations in electrical impulses in the brain. This provides information about brain activity in the most important areas of the cerebral cortex.
EEG is used to investigate
- Possible epilepsy
- Syncope (fainting)
- Memory disorders
EEGs are analyzed with the help of a computer. Frequency and strength of electrical activity is measured in different areas of the brain, and in correlation to neighboring areas.
The principal advantages are:
- Precise mapping of electrical activity in graphic form
- Potential for comparison with previous examinations using the database
- More accurate diagnostics through objective analysis of measurement data
