To understand further relationships of the interictal electroencephalogram to the aura in complex partial seizures (CPS), we studied the interictal EEG and aura in 144 patients with CPS. The ages of the patients studied ranged from 31 to 80 years (average 52.44 years). The duration of seizures ranged from 1 to 60 years (average 15.69 years). Seventy(More)
Treiman has described five electroclinical stages through which the EEG progresses during generalized convulsive status epilepticus (GCSE). The EEG can show similar patterns in patients with complex partial status epilepticus (CPSE), but there is no agreement as to whether the different patterns seen in the human EEG result from a similar orderly(More)
Propofol is a relatively new anesthetic agent used in outpatient surgery. Some investigators use it in the treatment of status epilepticus and in epilepsy surgery and have concluded that propofol has an anticonvulsant effect. Cases of seizure-like behaviors, myoclonus and opisthotonus following propofol anesthesia have been reported. Although rare, official(More)
Determining the cause of seizures is a significant medical problem, as misdiagnosis can result in increased morbidity and even mortality of patients. The reported research evaluates the efficacy of using an artificial neural network (ANN) for determining epileptic seizure occurrences for patients with lateralized bursts of theta (LBT) EEGs. Training and(More)
PURPOSE Attending to psychological support and education from the time of diagnosis will assist patients in their acceptance of the need for psychological services. DESIGN AND METHODS An intervention was provided at the time of diagnosis of psychogenic nonepileptic seizures. This randomized control pilot study examined outcomes 6-8 weeks after discharge(More)
The widespread use of the routine EEG in clinical practice was a major development in the treatment of patients with ill-defined spells thought to be epileptic. Not every finding on the EEG is suggestive of epilepsy, and the EEG is subject to over-interpretation, which may lead to misdiagnosis and incorrect treatment. Although supplemented by other(More)
The topic of transitory impairment of consciousness with spike wave bursts has been of interest to neurologists for years. Based on some early experiments, a 3-second rule was formulated and has found its way into the conventional wisdom of neurology. It states that, in order to result in impairment of consciousness, a spike-wave burst must be of at least 3(More)
The anterior temporal cerebral region is not well covered, electroencephalographically, by the usual EEG electrodes. Numerous attempts have been made to add anterior temporal electrodes. There has been discussion regarding the amount of additional information actually attributable to those electrodes. We systematically evaluated the abnormalities revealed(More)
