Parvovirus B19 as a trigger to anti-n-methyl-d-aspartate receptor (NMDAR) encephalitis

Key Points

• Anti-n-methyl-d-aspartate receptor encephalitis is linked to parvovirus B19 infection.
• In cases of NMDAR encephalitis, autoimmune responses were observed in several patients.
• Analysis of clinical cases shows neuroinflammation triggered by viral infection.
• Findings suggest that parvovirus B19 may serve as an environmental trigger for autoimmune responses.
