Association between kinetic semiology of psychogenic nonepileptic spells and seizure type in dual disorder.

Purpose: Epilepsy is diagnosed in 20% of patients with psychogenic nonepileptic spells (PNES). The semiology of PNES and epileptic seizures (ES) overlaps in some patients. It is unclear whether the motor phenotype of PNES predicts the type of ES.

Limited-Montage EEG as a Tool for the Detection of Nonconvulsive Seizures.

Purpose: Prefabricated arrays with a limited number of electrodes offer an opportunity to hasten the diagnosis of seizures; however, their accuracy to detect seizures is unknown. We examined the utility of two limited-montage EEG setups for the detection of nonconvulsive seizures.

Methods: Thirty previously interpreted EEG segments with nonconvulsive seizures from 30 patients and 60 segments with background slowing or normal EEG from 60 patients were rendered in a bipolar "double banana" montage, a double distance "neonatal" montage, and a circumferential "hatband" montage.

Towards Successes in the Management of Nonconvulsive Status Epilepticus: Tracing the Detection-to-Needle Trajectories.

Purpose: Data on the timeliness of emergent medication delivery for nonconvulsive status epilepticus (NCSE) are currently lacking.

Methods: Retrospective chart reviews (between 2015 and 2018) and analyses of all patients with NCSE were performed at the University of Nebraska Medical Center, a level 4 epilepsy center, to determine the latencies to order and administration of the first, second, and third antiepileptic drugs (AEDs). Recurrent NCSE cases were considered independently and classified as comatose and noncomatose.

Utilization of brain imaging in evaluating patients with psychogenic nonepileptic spells.

Background: Psychogenic nonepileptic spells (PNES) are paroxysmal movements or sensory events that resemble epileptic seizures but lack corresponding ictal electrographic changes. A confirmed diagnosis of PNES is only accomplished via video electroencephalogram (vEEG) monitoring. Prior to diagnosis, patients are often assessed with neurodiagnostic imaging and their conditions treated with anticonvulsant medications, both of which are of limited clinical value and contribute to the higher cost of care.
