How do they know that whiplash or trauma doesnt cause this kind of influence to the brain thus causing a false impression.
Are the saying that the diagnostic tool that they have been using for years up until now is the incorrect one
The number of lesions found in a MS patient's white matter has been one criteria for many years in helping diagnose MS. But notice I say "helping diagnose" MS. The docs normally don't base a final diagnosis on MRI lesions alone.
The drug companies, in their trials, have used the number of MS lesions in white matter MRIs as their measurement that the the particular drug is working...or not. Yet there is little correlation between lesions and MS symptoms. But hey, if it helps a drug get approved and brings in millions of dollars of revenue...why not?
Now they have machines that can measure grey matter lesions which appear to be a far more accurate in determining the level of MS one has.
Changing the criteria to suite the diagnosis...who knows but I would have far more reliance on grey matter lesions than anything in the past.
