Description:Organized by wave features rather than pattern names, this atlas helps guide the reader to an EEG interpretation even when the waveform is unfamiliar. The first section takes the reader through the process of characterizing EEG waves by their features. The second section organizes EEG patterns by their features, so provides EEG waveform differential diagnoses. The third section is organized alphabetically by pattern name with each pattern described in a way that allows the reader to distinguish it from similarly appearing patterns. Examples of the patterns also are provided.
