McDonald criteria



The McDonald criteria are diagnostic criteria for multiple sclerosis. In April 2001 an international panel in association with the National Multiple Sclerosis Society (NMSS) of America recommended revised diagnostic criteria for ms. They make use of advances in MRI imaging techniques and are intended to replace the Poser criteria and the older Schumacher criteria. The new criteria facilitate the diagnosis of MS in patients who present with signs and symptoms suggestive of the disease. These include monosymptomatic disease, disease with a typical relapsing-remitting course or insidious progression but no clear attacks and remissions.

Additional recommended knowledge

The McDonald criteria for the diagnosis of multiple sclerosis were revised in 2005 to clarify exactly what is meant by an "attack," "dissemination," a "positive MRI," etc (Polman et al 2005).

Diagnostic Criteria

Clinical Presentation Additional Data Needed
* 2 or more attacks (relapses)
* 2 or more objective clinical lesions
None; clinical evidence will suffice (additional evidence desirable but must be consistent with MS)
* 2 or more attacks
* 1 objective clinical lesion
Dissemination in space, demonstrated by:
* MRI
* or a positive CSF and 2 or more MRI lesions consistent with MS
* or further clinical attack involving different site
* 1 attack
* 2 or more objective clinical lesions
Dissemination in time, demonstrated by:
* MRI
* or second clinical attack
* 1 attack
* 1 objective clinical lesion
(monosymptomatic presentation)
Dissemination in space by demonstrated by:
* MRI
* or positive CSF and 2 or more MRI lesions consistent with MS
and
Dissemination in time demonstrated by:
* MRI
* or second clinical attack
Insidious neurological progression
suggestive of MS
(primary progressive MS)
Positive CSF
and
Dissemination in space demonstrated by:
* MRI evidence of 9 or more T2 brain lesions
* or 2 or more spinal cord lesions
* or 4-8 brain and 1 spinal cord lesion
* or positive VEP with 4-8 MRI lesions
* or positive VEP with <4 brain lesions plus 1 spinal cord lesion
and
Dissemination in time demonstrated by:
* MRI
* or continued progression for 1 year
