Diagnosis will incorporate at least 1 of the following 6 core clinical characteristics, all evident on MRI1:

Optic-neuritis

Optic neuritis

symptomatic-narcolepsy-icon

Symptomatic narcolepsy or acute diencephalic clinical syndrome with diencephalic lesions on MRI that are characteristic of NMOSD

acute-myelitis-icon

Acute myelitis

symptomatic-cerebral-syndrome-icon

Symptomatic cerebral syndrome with brain lesions that are characteristic of NMOSD

Area-postrema-syndrome

Area postrema syndrome

brain-stem-inflammation-icon

Acute brain stem syndrome (with associated periependymal brain stem lesions on MRI in AQP4-IgG negative patients)

Monitoring treatment efficacy should be part of any long-term treatment plan2

Clinical markers and patient symptoms provide important information about disease activity3,4

  • MRI

  • Serum
    Biomarkers

  • Sleep
    Disorders

  • Pain

MRI scan icon

May be a predictive tool of disease severity and the potential for attack recovery5,6

  • Longer lesion length, presence of Gd enhancement, and central cord involvement are associated with higher EDSS scores5,6
  • MRI may help discriminate relapses from pseudorelapses and determine if a change in therapy is warranted6

Serum cell-based assay test icon

Levels at onset may help indicate future disease course and disease severity3

  • Higher levels of sNfL have been correlated with higher EDSS scores at disease onset3
  • Increased levels of sGFAP are associated with an increased risk and intensity of NMOSD attack7
  • B-cell counts may be helpful in assessing a patient’s risk for major attack8
  • AQP4-IgG titers may indicate disease severity during the attack phase9

Sleep disorders icon

May be a factor of predictive value in NMOSD attack4

  • Sleep disturbance is common among the NMOSD population4
  • The frequency of sleep disturbance increases around the time of acute NMOSD attack4

Acute myelitis icon

Common and associated with reduced QOL10

  • In a survey of 166 patients with NMOSD, 75% suffered from chronic pain10
  • NMOSD-associated pain severity has been strongly correlated with reduction of activities of daily living10

Any new or worsening symptom (eg, tingling, numbness, vision loss, sleep disturbance) should be investigated as a potential sign of attack recurrence and loss of therapeutic efficacy2,11

EDSS, Expanded Disability Status Scale; Gd, gadolinium; sGFAP, serum glial fibrillary acidic protein; sNfL, serum neurofilament light chain.
