Overview
Japanese encephalitis must be differentiated from other diseases that cause nondescript symptoms, which include fever, headache, and vomiting, such as meningitis, brain abscess, and other demyelinating diseases.
Differentiating Japanese encephalitis from Other Diseases
Japanese encephalitis must be differentiated from other diseases that cause fever, headache, and vomiting, such as:[1][2][3][4][5]
| Disease | Similarities | Differentials |
|---|---|---|
| Meningitis | Classic triad of fever, nuchal rigidity, and altered mental status | Photophobia, phonophobia, rash associated with meningococcemia, concomitant sinusitis or otitis, swelling of the fontanelle in infants (0-6 months) |
| Brain abscess | Fever, headache, hemiparesis | Varies depending on the location of the abscess; clinically, visual disturbance including papilledema, decreased sensation; on imaging, a lesion demonstrates both ring enhancement and central restricted diffusion |
| Demyelinating diseases | Ataxia, lethargy | Multiple sclerosis: clinically, nystagmus, internuclear ophthalmoplegia, Lhermitte's sign; on imaging, well-demarcated ovoid lesions with possible T1 hypointensities (“black holes”)
Acute disseminated encephalomyelitis: clinically, somnolence, myoclonic movements, and hemiparesis; on imaging, diffuse or multi-lesion enhancement, with indistinct lesion borders |
| Substance abuse | Tremor, headache, altered mental status | Varies depending on type of substance: prior history, drug-seeking behavior, attention-seeking behavior, paranoia, sudden panic, anxiety, hallucinations |
| Electrolyte disturbance | Fatigue, headache, nausea | Varies depending on deficient ions; clinically, edema, constipation, hallucinations; on EKG, abnormalities in T wave, P wave, QRS complex; possible presentations include arrhythmia, dehydration, renal failure |
| Stroke | Ataxia, aphasia, dizziness | Varies depending on classification of stroke; presents with positional vertigo, high blood pressure, extremity weakness |
| Intracranial hemorrhage | Headache, coma, dizziness | Lobar hemorrhage, numbness, tingling, hypertension, hemorrhagic diathesis |
| Trauma | Headache, altered mental status | Amnesia, loss of consciousness, dizziness, concussion, contusion |
