Abstract

The number of domestic cases of pandemic H1N1 influenza A was elevated in 2009. The common clinical symptoms associated with H1N1 influenza include respiratory symptoms such as cough, sore throat, rhinorrhea, fever, chills, myalgia, and fatigue. Gastrointestinal symptoms are relatively common. H1N1 influenza A infection brings about neurological symptoms in rare cases. However, there are few reports about H1N1 influenza A infection with neurological manifestations. We recently experienced an H1N1 influenza A patient who presented with disturbed mental status, seizures, and focal changes on brain magnetic resonance imaging , associated with infection.
