[Use of automatic, computer-assisted EEG analysis in clinical practice].
Digital EEG-recorders are being increasingly accepted for clinical routine application, thereby offering the possibility for an automated computerised EEG evaluation. This paper presents the results of a corresponding computer programme developed in our group. Based on 313 clinical routine-EEG we compared the computer reports to the visual EEG-interpretations and obtained the following result: Background activity is reliably detected with a rate comparable to a human interpreter. Similar results were observed with focussed pathological activity. Intermittent activity (Parenrhythmia, dysrhythmia) however lacks a sufficiently high score of correct evaluation and requires further development. Epileptiform potentials, especially spikes, are detected with high sensitivity, however, at the cost of low specificity, and are therefore still in need of further improvement.
