Multidisciplinary Rehabilitation for Relapsing Myelin Oligodendrocyte Glycoprotein Antibody-associated Disease: A Case Report

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is an inflammatory central nervous system disease that is driven by antibodies of the immunoglobulin G1 class. MOGAD has recently been recognized as an autoimmune disease; therefore, little is known about its rehabilitation. Here, we present a case of MOGAD that showed significant recovery after rehabilitation. A 58-year-old woman developed weakness in all extremities, dysarthria, and dysphagia. She visited the neurology department, and early brain and spine magnetic resonance imaging showed multifocal high intensity in the subcortical and periventricular white matter and the cervical cord. The patient's serum tested positive for anti-MOG antibodies. She was diagnosed with MOGAD and received intravenous steroid pulse therapy. After pharmacologic therapy, the patient was transferred to the rehabilitation department. Initially, her Functional Independence Measure (FIM) motor score was 26, allowing her to stand independently for only a few seconds. After 5 weeks of rehabilitation involving physical therapy, occupational therapy, and balance training, her FIM motor score improved to 60. However, 4 months after discharge, the disease relapsed with symptoms of motor weakness in all extremities, and steroid treatment was initiated. On the second admission, her FIM motor score was 42, but after continuous multidisciplinary rehabilitation, it improved to 76. Computerized cognitive therapy improved her cognitive function, from a Korean version of the Mini-Mental State Examination score of 23 on the first admission to 30 on final discharge. Since MOGAD is a relapsing disease, a favorable outcome can be achieved with continuous monitoring and multidisciplinary, symptom-specific rehabilitation.
