New onset refractory status epilepticus (NORSE) versus refractory status epilepticus not meeting NORSE criteria: A comparative clinical and electroencephalography‐based study

Epilepsia, EarlyView.
Abstract Objective New onset refractory status epilepticus (NORSE) is a rare, severe presentation of refractory status epilepticus (RSE), with approximately half of cases cryptogenic NORSE (c‐NORSE). We compared electroencephalographic (EEG) findings alongside clinical features between NORSE and RSE not meeting NORSE criteria to better understand ...
