Enteroviral encephalitis
Clinical Classification Guidelines
Inclusion Terms
- Enteroviral encephalomyelitis
Medical Intelligence & Overview
Enteroviral encephalitis is an infection of the brain caused by enteroviruses, a group of viruses that are common worldwide. This condition leads to inflammation in the brain, which can impact various neurological functions. Although it can be serious, early diagnosis and management are critical for better outcomes. Recognized under the ICD-10 code A85.0, enteroviral encephalitis primarily affects children but can occur at any age.
Causes & Symptoms
Clinical Causes: Infection with enteroviruses such as Coxsackieviruses, Echoviruses, and Polioviruses Transmission through contact with contaminated fecal matter, saliva, or respiratory secretions Ingesting contaminated food or water Close contact with an infected individual Less commonly, through contaminated surfaces or objects
Key Symptoms: Fever and chills Headache and neck stiffness Sensitivity to light (photophobia) Confusion or altered mental state Seizures in some cases Nausea and vomiting Fatigue and general malaise Muscle weakness or paralysis (rare)
Diagnostic & Treatment
Diagnosis Path: - A detailed medical history and physical examination, focusing on neurological symptoms - Blood tests to identify specific antibody responses or viral markers - Lumbar puncture (spinal tap) to analyze cerebrospinal fluid (CSF) for signs of infection and detect enteroviruses through PCR testing - Neuroimaging studies such as MRI or CT scans to observe brain inflammation or damage - Additional tests may include viral cultures or serology to confirm the specific virus involved
Treatment Protocols: - Hospitalization in severe cases for close monitoring - Rest and hydration to support immune response - Fever management with antipyretics - Medications to control seizures if they occur - Physical therapy and supportive interventions for neurological deficits - Prevention of complications like secondary infections - In some cases, intravenous immunoglobulin (IVIG) therapy may be considered, although its effectiveness varies
