Electroclinical features of seizures in myelin oligodendrocyte glycoprotein antibody-associated cerebral cortical encephalitis: a case report and literature review

Myelin oligodendrocyte glycoprotein (MOG) antibodies (Abs) are detected in demyelinating diseases of the central nervous system, including acute disseminated encephalomyelitis in children and anti-aquaporin 4 Ab-negative neuromyelitis optica spectrum disorders. Recently, the spectrum of MOG-Ab–associated diseases (MOGADs) has been widened, and cerebral cortical encephalitis (CCE) with MOG-Ab positivity has been recognized as a MOGAD [1]. Patients with MOG-Ab–associated CCE (MOG-CCE) often have seizures, but they may lack other clinical features that suggest encephalitis, including fever, encephalopathy, and focal neurological deficits.
