Brain lesions in CIDP -> what the studies show
There was a small UK study in 1990 that showed 14 of 28 CIDP patients had brain lesions of some sort. Only 6 of them showed symptoms of CNS issues.
A similar study in Japan in 2007 showed similar results. Of the 18 CIDP patients, 5 had abnormal MRIs and another had CNS issues found through a different method. (I read the whole paper, but I’m not a medical doctor, and couldn’t quite decide what fraction of the 5 with abnormal had CNS-related symptoms.)
Anyway, having an MRI that shows lesions (aka “white spots”) doesn’t seem to be unusual for CIDP patients and doesn’t necessarily mean much.
