TL;DR: It appears that the patients at highest risk for NCSE can be identified, and this should provide a basis for further studies designed to determine the clinical significance of various EEG patterns and to develop preventative strategies.

Abstract: Object Nonconvulsive status epilepticus (NCSE) is an underrecognized and poorly understood complication of aneurysmal subarachnoid hemorrhage (SAH). The authors evaluated the risk factors, electroencephalographic (EEG) characteristics, hospital course, and clinical outcomes associated with NCSE in a population with SAH treated at a single institution. Methods The hospitalization and outcome data were reviewed in 11 patients who had received a diagnosis of NCSE and SAH. The study included individuals from a cohort of 389 consecutive patients with SAH who were treated between March 2003 and June 2005, and who were analyzed retrospectively. The patients' medical history, neurological grade, events of hospitalization, EEG morphological patterns, and disposition were analyzed. Advanced age, female sex, need for ventriculostomy, poor neurological grade (Hunt and Hess Grade III, IV, or V), thick cisternal blood clots, and structural lesions (intracerebral hemorrhage and stroke) were common in the population with...

Seizures and anticonvulsants after aneurysmal subarachnoid hemorrhage.
TL;DR: When prophylaxis is used, 3-day treatment seems to provide similar seizure prevention with better outcome compared with longer-term treatment, and non-convulsive seizures should be considered in patients with poor neurological status or deterioration.

Electrophysiologic Monitoring in Acute Brain Injury
Jan Claassen,Paul M. Vespa +1 more
TL;DR: Electroencephalography should be considered in all patients with ABI and unexplained and persistent altered consciousness and in comatose intensive care unit (ICU) patients without an acute primary brain condition who have an unexplained impairment of mental status, and uncertainty remains on other applications.

Continuous EEG monitoring in ICU
TL;DR: No definitive diagnostic criteria exist for identifying EEG patterns suggestive of nonconvulsive status epilepticus (NCSE), especially the ambiguous significance of periodic discharges (PDs) further complicates the diagnosis of NCSE.
Utility of levetiracetam in patients with subarachnoid hemorrhage
TL;DR: In patients with SAH, LEV appears to have superior tolerability compared to PHT, and after switching to LEV, all adverse effects resolved except gastrointestinal disturbance and worsening mental status in 4 patients.

Levetiracetam compared to valproic acid: plasma concentration levels, adverse effects and interactions in aneurysmal subarachnoid hemorrhage
TL;DR: Though this finding needs further verification, the enteral liquid application of levetiracetam seems to be associated with lower bioavailability than the common oral application of LEV, and the use of the antibiotic drug meropenem together with valproic acid leads to lower pc levels in patients treated with of valproIC acid.

ASSESSMENT OF COMA AND IMPAIRED CONSCIOUSNESS: A Practical Scale
Graham M. Teasdale,Bryan Jennett +1 more
TL;DR: A clinical scale has been evolved for assessing the depth and duration of impaired consciousness and coma that facilitates consultations between general and special units in cases of recent brain damage, and is useful also in defining the duration of prolonged coma.

Surgical Risk as Related to Time of Intervention in the Repair of Intracranial Aneurysms
William E. Hunt,Robert M. Hess +1 more
TL;DR: The modification of Botterell's classification 3 has been applied to 275 consecutive cases of intracranial aneurysm treated by the faculty and resident staff of the Ohio State University and affiliated hospitals over a 12year period and is of the opinion that a fairly sharp differentiation is possible among patients who have few or no meningeal signs, patients who has welldefined meningealing signs but no neurological deficit, and patients who show neurological malfunction.

Relation of Cerebral Vasospasm to Subarachnoid Hemorrhage Visualized by Computerized Tomographic Scanning
TL;DR: The results indicate that blood localized in the subarachnoid space in sufficient amount at specific sites is the only important etiological factor in vasospasm and it should be possible to identify patients in jeopardy from vasospasms and institute early preventive measures.

TL;DR: As initial intravenous treatment for overt generalized convulsive status epilepticus, lorazepam is more effective than phenytoin and it is easier to use.
Detection of electrographic seizures with continuous EEG monitoring in critically ill patients
TL;DR: Coma, age <18 years, a history of epilepsy, and convulsive seizures prior to monitoring were risk factors for electrographic seizures.
