hi
I had brain leisons on MRI that looked like MS. Had repeat MRI 3 times. Has had multiple neurological symptoms. But doctors say it is not MS

I saw a special neurologist, he said that Sjoegren syndrome has very similar brain lesions and symptoms.
He tested me for that with biopsy, but biopsy and blood test negative.

What symptoms do you have?
Are you seeing a neurologist?

You could look up Sjoegrens, and other autoimmune disorders.
