Lyme can cause a chronic encephalomyelitis that resembles multiple sclerosis. Blocking PD-L2 has been shown to exacerbate experimental autoimmune encephalomyelitis. Demyelinating lesions of MOG-associated encephalomyelitis resemble more those observed in multiple sclerosis than NMO. Differential diagnosis include riboflavin deficiency and avian encephalomyelitis. Begum suffers from chronic fatigue syndrome, also known as myalgic encephalomyelitis (ME). It also can appear associated with encephalomyelitis and parkinsonism. BCoV has 95% similarity with human coronavirus OC43 and 93% to porcine hemagglutinating encephalomyelitis virus. Louping ill virus is a flavivirus (RNA virus), also known as sheep encephalomyelitis virus. In older dogs that develop distemper, encephalomyelitis and vestibular disease may be present. Muscle tremor is typical of avian encephalomyelitis. The autopsy also found that Levy had hepatitis, encephalomyelitis, and coronary atherosclerosis. The California quail is easily infected with western equine encephalomyelitis virus (WEEV). The relationship between ADEM and anti-MOG associated encephalomyelitis is currently under research. Rarely, a progressive form of encephalomyelitis may occur. This is a list of notable people diagnosed with Myalgic Encephalomyelitis (ME).
