Abstract

Anti-LGI1 (leucine-rich glioma inactivated-1) antibody encephalitis is one of autoimmune encephalitis. We report a 66-year-old man who presented with frequent, brief dystonic seizures which involve predominantly ipsilateral face and arm without cognitive impairment. Brain MRI showed normal finding. Serum and CSF tests revealed anti-LGI1 antibody. His symptom was not relieved by antiepileptic drugs, but completely controlled after immunotherapy. This case indicates that recognition of the brief, dystonic seizures should do tests for anti-LGI1 antibodies. Key Words: Autoimmune encephalitis, LGI1, Voltage gated potassium channel
