PURPOSE Convulsive status epilepticus (CSE) is a major medical and neurological emergency that is associated with significant morbidity and mortality. Despite this high morbidity and mortality, most acute care facilities in the United States cannot evaluate patients with EEG monitoring during or immediately after SE. The present study was initiated to(More)
Since its inception 30 years ago, AEEG has continued to evolve--from four-channel tape recorders to 32-channel digital recorders with sophisticated automatic spike and seizure detection algorithms. AEEG remains an important tool in epilepsy evaluation. In the near future, smaller, faster, and more sophisticated AEEGs will be developed. Seizure(More)
We prospectively compared the clinical course of 119 patients treated for status epilepticus (SE) in private practice community hospitals and 344 SE patients treated in the VCU university hospitals in Richmond, Virginia USA over a 2-year period to test the hypothesis that SE presents with the same mortality and clinical patterns in both clinical settings.(More)
In cases of refractory status epilepticus (RSE) unresponsive to sequential trials of multiple agents, a suspension of topiramate administered via nasogastric tube was effective in aborting RSE, including one patient in a prolonged pentobarbital coma. Effective dosages ranged from 300 to 1,600 mg/d. Except for lethargy, no adverse events were reported.
PURPOSE Status epilepticus (SE) is a major medical and a neurologic emergency associated with significant morbidity and mortality. The current definition of SE is continuous seizure activity or intermittent seizure activity without regaining consciousness, lasting > or =30 min. Epilepsy monitoring unit data indicate that many seizures self-terminate within(More)
Ischemic brain injury (stroke) is a major cause of status epilepticus (SE). In our database of 529 adult SE cases, acute or remote cerebrovascular accidents (CVA) were a primary cause of SE for 41% of the patients overall and for 61% of the elderly patients. SE in the setting of acute CVA has a very high mortality, approaching 35%. The degree to which(More)
Ms. Q, a 29-year-old woman, began to behave strangely, claiming to see and hear imaginary people. The following day, she was confused and somnolent in the morning. In the late morning, she had a generalized tonic-clonic seizure and was transported to the hospital. Her past medical and developmental histories were unremarkable. She took a daily oral(More)
Acute symptomatic seizures and epilepsy are two of the most common neurologic complaints in the elderly. Stroke is the leading underlying etiology for both. Because clinical seizure manifestations in the elderly often differ from those in younger adults, they may be difficult to recognize or may be misdiagnosed. Interpretation of diagnostic tests in elderly(More)
To develop expert consensus for conversion between antiepileptic drug (AED) monotherapies, an 11-member panel used the Delphi Technique over three rounds to: (1) identify relevant issues, (2) vote on the issues, and (3) develop consensus. The panel agreed on the basic principle to taper the existing AED only after a presumably efficacious dose of the(More)
Status epilepticus (SE) is a medical and neurological emergency that has been associated with significant morbidity and mortality. The most widely accepted definition of SE is more than 30 minutes of either continuous seizure activity, or intermittent seizures without full recovery of consciousness between seizures. SE is a major clinical concern in the(More)
