Summary
This chapter provides a framework for the reader to describe abnormalities of the electrographic background and foreground. The electrographic background may be described based on symmetry, continuity, voltage, organization, reactivity, and sleep architecture. A waveform or potential abnormality may be described based on its location, occurrence (sporadic or repetitive – rhythmic or periodic), and morphology (slow or sharp wave). Further, this description can be qualified based on modifiers such as prevalence, frequency, duration, and amplitude. When reporting waveforms, the modifiers should precede the key features in your description. [88 words/557 characters]
