Research Article: Clinical Features of Patients with Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease and Isolated Seizure Symptoms
Abstract:
Myelin oligodendrocyte glycoprotein (MOG) is a membrane protein uniquely expressed in the outermost lamellae of the myelin sheath in oligodendrocytes of the central nervous system (CNS).– MOG antibody–associated disease is a new clinical phenotype of inflammatory demyelinating disease.– In particular, MOG antibody–associated encephalitis is mostly characterized by acute-disseminated encephalomyelitis, multiphasic disseminated encephalomyelitis, neuromyelitis optica spectrum disorder, optic neuritis, myelitis, encephalitis, brainstem encephalitis, and a series of less typical syndromes such as encephalitis-like seizures, involuntary movement, nausea, vomiting, hiccups, and cranial neuritis.– Compared with multiple sclerosis and aquaporin- antibody–associated disease, MOG antibody–associated disease is an age-dependent demyelinating disease; adults have a lower prevalence than children (the positive frequency in adults is nearly half of that in children [–% vs –%]), and many patients present with the ophthalmoneuromyelitis phenotype.– Recent evidence increasingly indicates that patients with CNS demyelinating events who are MOG antibody–positive present with isolated seizures., However, there are gaps in the epidemiological knowledge regarding seizures in adults with this disease. In this study, we reported and analyzed the occurrence and evolution of isolated symptomatic seizures in MOG antibody–positive patients to characterize the clinical symptoms, treatment effects, and prognoses.
