Anti-GAD associated post-infectious cerebellitis after COVID-19 infection

The coronavirus disease 2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to spread rapidly all over the world. Besides severe pneumonia, it causes multisystemic disease, including neurological findings. Here, we present a patient with anti–glutamic acid decarboxylase (anti-GAD) antibody-associated cerebellitis developed after COVID-19 infection. The patient responded well to the immune treatments. Our knowledge about SARS-CoV-2 infection–related neurological disorders is limited. New data are needed to recognize the clinical spectrum of autoimmune neurological disorders that emerges after SARS-CoV-2 infection.
