Studies on cognitive impairment in neuromyelitis optica: Chinese scholars' reports published abroad

Neuromyelitis optica (NMO) is now classified as an autoimmune astrocytopathic disease targeting aquaporin 4 (AQP4). NMO can affect cerebral hemisphere beyond optic nerve and spinal cord, resulting in cognitive impairment. In recent years, cognitive impairment in NMO has been increasingly concerned. The characteristics of cognitive impairment in NMO and its neuropathological mechanism have been researched in many studies. This paper selected two high-quality studies by Chinese scholars regarding cognitive impairment in NMO which were published in foreign journals during the past 2 years, and focused on study methods and results.
