J Infect Chemother. 2012 Dec;18(6):961-4. doi: 10.1007/s10156-012-0413-8. Epub 2012 Apr 14.


Influenza virus is associated with a variety of neurological complications, of which the most commonly encountered are seizures and encephalopathy. Acute encephalitis and postinfectious encephalopathy have been reported infrequently in association with influenza A and B virus infections. We describe two previously healthy adults who presented with encephalopathy with a virologically documented influenza B infection.
