Encephalitis
Symptoms and Signs of Encephalitis
Symptoms of encephalitis include fever, headache, and altered mental status, often accompanied by seizures and focal neurologic deficits. A gastrointestinal (GI) or respiratory prodrome may precede these symptoms. Meningeal signs are typically mild and less prominent than other manifestations. Status epilepticus , particularly convulsive status epilepticus, or coma suggests severe brain inflammation and a poor prognosis. Olfactory seizures, manifested as an aura of foul smells (rotten eggs, burnt meat), indicate temporal lobe involvement and suggest HSV encephalitis.
