We describe the first case of a patient with eyelid tremor probably associated with anti-contactin-associated protein-like 2 (Caspr2) antibody. Encephalitis associated with anti-voltage-gated potassium channel antibody is now attributed to autoantibodies against leucine-rich glioma inactivated 1 (Lgi1) and less frequently against Caspr2. Eyelid tremor or blepharoclonus is a rare or underdiagnos...
