Post-Herpetic Anti-NMDAR Encephalitis in Denmark: Current Status and Future Challenges.

ABSTRACT: It is well known that N-methyl-D-aspartate receptor encephalitis (NMDARE) can be triggered by infectious encephalitis such as herpes simplex virus 1 encephalitis (HSE). However, the incidence of post-HSE NMDARE in Denmark is unknown. We reviewed literature cases and compared these to retrospectively identified cases of post-HSE NMDARE in Denmark, using a national cohort database of autoimmune encephalitis (AE) and two regional databases of infectious encephalitis patients. We identified 80 post-HSE NMDARE cases in the literature, 66% being children, who more often presented movement disorders, decreased consciousness, and sleep disturbances compared to adults. Eight patients with post-HSE NMDARE were identified from the national cohort database of AE, none being children. Forty-four
