Purpose of the Review <p>Continuous electroencephalography (cEEG) is widely used in the critical care setting for detection and management of seizures, as well as a broad range of other indications that we discuss in this review using case examples.</p> Recent Findings <p>Detection of non-convulsive seizure is the most common indication of cEEG. Non-convulsive seizures (NCS) are frequently encountered in the critical care setting and can be seen across heterogeneous diagnosis including after generalized convulsive status epilepticus, in patients with acute stroke, moderate-severe traumatic brain injury, anoxic brain injury, and in patients with metabolic encephalopathy. cEEG should be obtained as soon as possible when NCS are suspected as increasing burden of seizures is associated with worse functional and cognitive outcome. Shorter 30–60-min EEGs may detect seizures in approximately 50% of patients with non-convulsive seizures, while 24–48-h recordings can identify seizures in 90% or more patients with non-convulsive seizures. Quantitative EEG can assist in rapid screening and review of prolonged EEG recordings. cEEG is also used to guide anti-seizure treatment and monitoring depth of sedation. Recently, advances have been made in the use of cEEG for prognostication, particularly in patients with anoxic brain injury, and for ischemia detection in patients with aneurysmal subarachnoid hemorrhage.</p> Summary <p>There has been a significant increase in the utilization of cEEG in neurocritical care. Future directions include determining the impact of cEEG guided treatment on outcomes, integrating cEEG into multimodal monitoring, and advances in artificial intelligence tools to increase access and feasibility of cEEG in day-to-day care.</p>
