Overview
Acute neurological rabies is a severe, often fatal condition characterized by progressive encephalitis leading to significant neurological deterioration and high mortality rates 13.Diagnosis
Clinical presentation includes acute onset of fever, headache, altered mental status, and neurological symptoms such as confusion, agitation, or paralysis 1.
Diagnostic confirmation typically involves detecting rabies virus-specific antigens or nucleic acids in cerebrospinal fluid (CSF) or brain tissue via PCR or immunohistochemistry 1.
Imaging studies (CT/MRI) may show nonspecific findings such as cerebral edema or mass effect 13.Management
Supportive Care: Maintaining airway, ventilation, and hemodynamic stability 13.
Intracranial Pressure Management: Monitoring and managing increased intracranial pressure to prevent herniation; use osmotic diuretics like mannitol and ensure adequate cerebral perfusion pressure 4.
Antiviral Therapy: Post-exposure prophylaxis with rabies immunoglobulin and vaccine if administered early; no specific antiviral treatment for established cases 1.
Infection Control: Strict isolation to prevent transmission 1.Special Populations
Pediatrics: Early recognition and rapid intervention are crucial due to higher vulnerability and potential for better outcomes with timely management 2.
Elderly: Higher risk of comorbidities affecting prognosis; management focuses on supportive care and addressing secondary complications 3.Key Recommendations
Early and accurate diagnosis through clinical assessment and laboratory testing (CSF analysis, imaging) is critical for prognosis and management 13 (Evidence: Strong).
Aggressive management of increased intracranial pressure is essential to prevent neurological deterioration and mortality 4 (Evidence: Moderate).
Supportive care measures, including ventilation and hemodynamic support, should be prioritized in acute neurological rabies 13 (Evidence: Strong).References
