Answer

The signs of encephalitis may be diffuse or focal. Typical findings include the following:

  • Altered mental status

  • Personality changes (very common)

  • Focal findings (eg, hemiparesis, focal seizures, and autonomic dysfunction)

  • Movement disorders (eg, St Louis encephalitis, eastern equine encephalitis, and western equine encephalitis)

  • Ataxia

  • Cranial nerve defects

  • Dysphagia, particularly in rabies

  • Meningismus (less common and less pronounced than in meningitis)

  • Unilateral sensorimotor dysfunction (postinfectious encephalomyelitis)
