„Unspezifische“ EEG- Veränderungen - Verlangsamungen fokal und generalisiert, Asymmetrien

Abnormal EEG are divided in “nonspecific” abnormal EEG pattern with low correlation to an underlying pathogenic process, and a more “specific” abnormal EEG pattern with a higher correlation to an underlying pathogenic process, realizing that “specific” abnormal EEG pattern sensu stricto does not exist. “Nonspecific” abnormal EEG pattern is described and illustrated by EEG recordings.
