Akinetic mutism and status epilepticus due to Epstein Barr virus encephalitis

Area of Science:

• Neurology
• Infectious Diseases
• Neuroimmunology

Background:

• Neurological complications from Epstein Barr virus (EBV) are rare, typically manifesting as mild encephalitis.
• The exact pathophysiology of EBV encephalitis, including potential autoimmune mechanisms, remains incompletely understood.

Observation:

• A 14-year-old boy presented with severe EBV encephalitis, characterized by extensive basal ganglia and cerebral cortex involvement.
• The patient exhibited atypical symptoms of akinetic mutism and non-convulsive status epilepticus, necessitating intensive care.
• Diagnostic workup revealed negative results for onconeuronal and synaptic antibodies, including those targeting the dopamine D2 receptor.

Findings:

• This case represents the first evaluation of dopamine D2 receptor antibodies in EBV encephalitis.
• Despite the aggressive presentation and basal ganglia involvement, intensive care management resulted in a favorable clinical outcome.
• The study underscores the variability in EBV encephalitis presentation and the critical role of intensive care.

Implications:

• The findings suggest that even severe EBV encephalitis can have a positive prognosis with appropriate intensive care.
• Further research is needed to elucidate the role of autoimmunity and optimize treatment strategies, including the controversial use of acyclovir and the potential benefit of corticosteroids.
• This case highlights the importance of considering EBV encephalitis in the differential diagnosis of acute neurological presentations, especially in younger individuals.
