NMOSD (Neuromyelitis Optica Spectrum Disorder)


Neuromyelitis Optica Spectrum Disorder (NMOSD) is a rare, relapsing autoimmune disease
that causes your immune system to attack your central nervous system. Uncontrolled
activation of a particular part of your immune system could trigger the next relapse
and people with NMOSD who test positive for aquaporin 4 (AQP4) antibodies have a high risk
of relapse. The complement system is a particular part of your immune system that
helps your body fight potential threats such as infection, but in NMOSD, AQP4
antibodies can lead to uncontrolled complement system activation that can damage your central nervous system.
