1.Diagnosis

4. Multiple Sclerosis Diagnosis

•Diagnosis relies on clinical judgment.
•MS is extremely variable.
•There is no specific test.
•The diagnosis has dramatic implications.

5. Multiple Sclerosis Diagnosis

Diagnosis of MS includes
To prove it is M.S
To exclude other
diagnoses

6. How to diagnose MS?
6


Clinical:
•History and examination.
•Evidence of CNS
involvement.
•Dissemination in space
and time.
Paraclinical:
•Neuroimaging.
•Evoked potentials.
•CSF analysis.

7. 7

8. Diagnostic Criteria
•Dawson criteria: 1916
•Schumacher criteria: 1965
•Poser criteria: 1983
•McDonald criteria: 2001
•McDonald criteria: 2005
•McDonald criteria: 2010
All criteria require dissemination in time and space

9. Summarized Diagnostic Criteria
1. Dissemination in space: Objective evidence
of neurological deficits localized to two
separate parts of the CNS

2. Dissemination in Time:
Onset of neurological deficits separated by
at least one month

3. Rule out other explanations!

•Clinically Isolated Syndrom + MRI

CSF examination:
•Abnormal in 85% to 90% of patients with MS.
•Elevated total IgG, an elevated IgG ratio, an increased IgG synthesis
rate,
•Presence of two or more oligoclonal bands in the CSF that are not
present in a simultaneously drawn serum sample

22. CSF examination
22


IgG index:
•[IgG
CSF/albumin
CSF]/[IgG
serum/albumin
serum]
MS patients elevated IgG index (>1.7). (normal is <0.77)

26. The Red Flags
26

27. Red flags
27


•Major red flags point fairly definitively to a non-MS diagnosis
•Intermediate red flags point to poor agreement and uncertainty
among raters about the weighting of the flag for differential
diagnosis in MS
•Minor red flags suggest that a disease other than MS should be
considered and fully explored, but an MS diagnosis is not excluded.

Normal Aging
•Periventricular caps
and bands
•Mild atrophy with
widening of sulci and
ventricles
•Punctate and
sometimes even
confluent lesions in the
deep white matter
(Fazekas I and II).

65. 65


Normal Aging

66. These white matter changes are classified
according to Fazekas:
66


•Mild - punctate WMLs: Fazekas I)
•Moderate - confluent WMLs: Fazekas II - in the deep white
matter can be considered normal in aging.
•Severe - extensive confluent WMLs: Fazekas III - always
abnormal.
