Electro-clinical evolution of refractory non-convulsive status epilepticus caused by West Nile virus encephalitis.

West Nile virus (WNV) has re-emerged with a much wider geographic distribution and a higher incidence than ever. In spite of some recent reports on the neurological manifestations and EEG changes caused by WNV encephalitis, there are few data on the incidence of seizures, status epilepticus or post-encephalitic epilepsy. There is also no systematic review of EEG changes caused by WNV encephalitis that is based on a large series of patients. Here, we review the pertinent literature, and report the electroclinical evolution and therapeutic complexity of a patient with WNV encephalitis who developed refractory, non-convulsive status epilepticus.
