Research progress in asymptomatic lesions of neuromyelitis optica spectrum disorders
Neuromyelitis optica spectrum disorders(NMOSD)are a group of autoimmune-mediated demyelinating diseases of the central nervous system.A growing number of studies have identified asymptomatic lesions on imaging in patients with NMOSD,including asymptomatic optic neuropathy,asymptomatic spinal lesions,and asymptomatic brain lesions,even in the absence of clinical symptoms.The characteristics of asymptomatic lesions of NMOSD,influencing factors,relationship with relapse and disability progression,and management strategies were reviewed in this article.
