The role of EEGs in the treatment and prognosis of epilepsy.

The significance of what is recorded in an electroencephalogram (EEG) can be easily misunderstood or misinterpreted. Even after years of use, it is still not an exact science. There appear to be many possible uses of the EEG but no clear agreement on its best use. Even its role in assessing the treatment, severity, progress and prognosis of epilepsy is varied. The need to find answers to questions around areas such as severity, treatment, progress and prognosis seems to be detracting from the area that the EEG can provide most help in: the classification of epileptic syndromes.
