Summary
This chapter uses a case-based approach to describe electrographic patterns associated with coma. These are rare and, though non-specific, may suggest particular underlying etiologies. The electrographic pattern of extreme delta brush (EDB) may be seen with anti-NMDA receptor encephalitis. Alpha-coma is a pattern of continuous unreactive alpha or alpha-theta range activity that may be seen in coma after cardiac arrest or in those with pontine injury. It may resemble normal wakefulness. Spindle-coma and beta-coma are also described. Electrocerebral inactivity (ECI) is the absence of all non-artifactual electrical activity on an EEG, when recording using minimal specified technical standards in patients with cerebral death (brain death).
