Objective: To quantify the effect of inhaled 5% carbon-dioxide/95% oxygen on EEG recordings from patients in non-convulsive status epilepticus (NCSE). Methods: Five children of mixed aetiology in NCSE were given high flow of inhaled carbogen (5% carbon dioxide/95% oxygen) using a face mask for maximum 120s. EEG was recorded concurrently in all patients. The effects of inhaled carbogen on patient EEG recordings were investigated using band-power, functional connectivity and graph theory measures…

Electroencephalographic criteria for nonconvulsive status epilepticus: Synopsis and comprehensive survey
TLDR
This compendium of patterns by NCSE syndrome classification with illustration of EEGs, and delineation of electroencephalographic features helps define the characteristics and semiologic borderlines among the types of NCSE.
Acute changes in carbon dioxide levels alter the electroencephalogram without affecting cognitive function.
TLDR
Modest changes in PETCO2 may cause significant alterations in the EEG without disturbing cognitive function, and this study examined whether modest changes in end-tidal PCO2 (PETCO2; a noninvasive measure of PaCO2) affect electroencephalographic (EEG) activity, cognitivefunction, and vigilance.
EEG criteria for nonconvulsive status epilepticus
Nonconvulsive status epilepticus (NCSE) represents a prolonged state of seizure(s) (status epilepticus—SE) without marked motor manifestations. NCSE typically encompasses an ictal impairment of
EFFECT ON THE ELECTRO-ENCEPHALOGRAM OF DRUGS AND CONDITIONS WHICH INFLUENCE SEIZURES
TLDR
By the use of patients with frequent minor disturbances, one can in the laboratory make a running record both of clinical seizures and of the lesser disturbances which give no clinical evidence of their presence.

TLDR
The diagnosis and management of nonconvulsive status epilepticus (NCSE) in children is described, a highly heterogeneous clinical condition that is understudied in the pediatric population.
‘Functional Connectivity’ Is a Sensitive Predictor of Epilepsy Diagnosis after the First Seizure
TLDR
The results indicate that epilepsy diagnosis could be improved by using functional connectivity, and theta band SL proved to be a significant predictor of a diagnosis of epilepsy.
Unified EEG terminology and criteria for nonconvulsive status epilepticus
TLDR
Flexible EEG criteria that employ the SCORE system to assemble a database for determining evidence‐based EEG criteria for NCSE are proposed.
Status epilepticus at an urban public hospital in the 1980s
TLDR
The clinical course of adult patients treated for generalized status epilepticus at the San Francisco General Hospital from 1980 to 1989 is reviewed to determine whether the etiologies of SE have changed over the last two decades, and to investigate the relationships between etiology, response to anticonvulsant therapy, and short-term clinical outcome.
