The diagnosis of nonconvulsive status epilepticus (NCSE) relies largely on electroencephalography (EEG) findings. The lack of a unified EEG terminology, and of evidence-based EEG criteria, leads to varying criteria for and ability to diagnose NCSE.

Nonconvulsive status epilepticus (NCSE) is an important and often unrecognized cause of impaired awareness especially in critically ill patients, which can easily be missed. Electroencephalography (EEG) findings in clinically suspected cases are the mainstay of …

2022年7月18日 · Nonconvulsive status epilepticus (NCSE) is defined as status epilepticus without a prominent (clinically obvious) motor component. NCSE may have zero motor components, or it may correlate with subtle movements (e.g., subtle facial twitching). NCSE may be diagnosed on the basis of either electrographic or electroclinical seizures: (33475321)

2024年7月7日 · Non-Convulsive Status Epilepticus (NCSE) is a persistent change in the level of consciousness, behaviour, autonomic function, and sensorium from baseline associated with continuous epileptiform EEG changes, but without major motor signs

2023年11月1日 · The mainstay of diagnosing NCSE is an electrographic seizure (ESz) and electrical status epilepticus (ESE) detected on EEG in the presence of clinical suspicion. In settings where EEG is not available, documented clinical improvement (CI) in a close temporal relationship with antiseizure medications (ASM) also suggests NCSE.

Various EEG patterns were found in patients with NCSE: (1) 8.2%, (2a) 2%, (2b) 12.2%, and (2c) 32.7%. Possible NCSE was diagnosed based on fluctuations in 57.1% and EEG improvement without clinical improvement in 14.2%.

Nonconvulsive status epilepticus (NCSE) is a state of continuous seizure activity for at least 30 minutes, with cognitive or behavioral changes. It may be classified according to EEG evidence of focal or generalized epileptic activity, but may be further categorized by etiology and level of consciousness, both with prognostic weight.

NCSE refers to large non-convulsive clinical symptoms caused by persistent EEG attacks, usually defined as >30 minutes. It is now recommended that the standard duration be reduced from 30 minutes to 5 minutes.

The Salzburg criteria for nonconvulsive status epilepticus (NCSE) and the American Clinical Neurophysiology Society (ACNS) Standardized Critical Care EEG Terminology 2021 include a diagnostic trial with intravenous (IV) antiseizure medications (ASMs) to assess electroencephalographic (EEG) and clinical response as a diagnostic criterion for ...

The analysis that follows presents clinical descriptions and EEG patterns of NCSE in the neonatal period, infancy, childhood, adulthood, and late adulthood from a syndromic perspective based on age, encephalopathy, cerebral development, etiology, and syndrome.
