Pain, depression and quality of life in adults with MOG-antibody associated disease

BACKGROUND AND PURPOSE: Myelin oligodendrocyte glycoprotein-antibody (MOG-ab)-associated disease (MOGAD) is an inflammatory autoimmune condition of the CNS. However, data on pain and depression have remained scarce. The aim of this study was to assess features of chronic pain and depression as well as their impact on health-related quality of life (hr-QoL) in MOGAD. METHODS: Patients with MOGAD were identified in the Neuromyelitis Optica Study Group (NEMOS) registry. Data were acquired by a questionnaire, including clinical, demographic, pain (PainDetect, Brief Pain Inventory - short form, McGill Pain Questionnaire - short form), depression (Beck Depression Inventory-II), and hr-QoL (Short Form-36 Health Survey) items. RESULTS: Twenty-two of 43 patients suffered from MOGAD-related pain (11 nociceptive, 8 definite neuropathic, 3 possible neuropathic) and 18 from depression. Patients with neuropathic pain had highest pain intensity and most profound ADL impairment. Fifteen patients reported spasticity-associated pain, including four with short-lasting painful tonic spasms. Later disease onset, profound physical impairment and depression were associated with chronic pain. Physical QoL was more affected in pain-sufferers (p
