Autoimmune Vestibulocerebellar Syndromes

This article describes the epidemiology, clinical presentation, diagnostic considerations, imaging findings, treatment, and prognosis of autoimmune disorders, in which the vestibulocerebellar syndrome is the main or presenting clinical presentation. Antibodies specific for intracellular antigenic targets described in the article are PCA-1 (Purkinje cell cytoplasmic antibody type 1, also known as anti-Yo), ANNA-1 (antinuclear neuronal antibody type 1, also known as anti-Hu), ANNA-2 (antinuclear neuronal antibody type 2, also known as anti-Ri), Ma1/2 (anti-Kelch-like 11/12 antibody), Kelch-like 11, amphiphysin, CV2 (collapsin response 2, also known as collapsin response mediator protein-5 [CRMP5]), VGCC (voltage-gated calcium channel), GAD65 (glutamic acid decarboxylase 65-kDa isoform), AP3B2 (adaptor protein 3B2, also known as anti-Nb), MAP1B (microtubule-associated protein 1B antibody, also known as anti-PCA-2), and neurochondrin antibodies. Antibodies targeting cell-surface or synaptic antigenic targets described in the article include DNER (delta/notchlike epidermal growth factor related receptor; antigen to anti-Tr), CASPR2 (contactin-associated proteinlike 2), septin-5, Homer-3, and mGluR1 (metabotropic glutamate receptor 1). The vestibulocerebellar presentation is largely indistinguishable among these conditions and is characterized by subacute onset of cerebellar symptoms over weeks to months. The diagnosis of autoimmune vestibulocerebellar syndromes is based on a combi...
