The signs and symptoms of MS can be similar to other medical problems, such as  [[Devic's disease|neuromyelitis optica]], [[stroke]], [[acute disseminated encephalomyelitis|brain inflammation]], [[infection]]s such as [[Lyme disease]] (which can produce identical MRI lesions and CSF abnormalities<ref>Garcia-Monco JC; Miro Jornet J; Fernandez Villar B; Benach JL; Guerrero Espejo A; Berciano JA.

==Differential Diagnosis==
== Differentiating multiple sclerosis from other diseases==
MS must be differentiated from the following diseases that may cause [[muscle weakness]], [[hypotonia]], or [[flaccid paralysis]]:
Multiple sclerosis must be differentiated from other diseases that can mimic this disease clinically or radiologically such as:

Overview

Differentiating multiple sclerosis from other diseases

Multiple sclerosis must be differentiated from other diseases that can mimic this disease clinically or radiologically such as:

Systemic immune-mediated diseases:

  • systemic lupus erythematosus
  • Behçet’s disease
  • sarcoidosis

Noninflammatory vascular syndromes:

  • Binswanger’s disease
  • Cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy (CADASIL)
  • Mitochondrial encephalopathies


Other demyelinating diseases:

  • Acute disseminated encephalomyelitis (ADEM)
  • Neuromyelitis optica (NMO)
  • Central pontine myelinolysis (CPM)

Infectious Diseases:

  • Progressive multifocal leukoencephalopathy (PML)
  • Human T-Cell leukemia virus 1 (HTLV1) Infection
  • Lyme disease

Metabolic diseases

  • Leukodystrophies

Normal aging phenomenon
