MOG and Alzheimer disease: Most reports of patients with co-occurrence of MOG-Ab and anti-NMDAR-Ab have shown that anti-NMDARe may develop initially, followed by MOG-AD[10]; however, patients with the opposite occurrence[11] or repetitive onset of anti-NMDARe attacks with no MOG-AD attacks (positive MOG-Ab just being a bystander) have also been reported.
