Encephalitis
Epileptic seizures were repeatedly described in a subgroup of MOGAD patients and are more common than in AQP4-IgG seropositive NMOSD (55–57), occurring in around 20% of all adult and paediatric MOGAD patients (58).
Encephalitis with and without seizures is now becoming increasingly recognised as an important clinical phenotype of MOGAD (58). Here, patients can show neuropsychiatric symptoms, behavioural changes, seizures, and memory or speech problems (59). Recently, encephalitis with MOG-IgG has been described as the most common type of autoimmune encephalitis in children (60).
