I had an mri. The impression on the report said minimal area of gliosis within the right insular cortex. What should I do?

Gliosis. Is rather non-specific brain inflammation, encountered in a multitude of neurologic conditions from post trauma scarring to multiple sclerosis or neurodegenerative disease. Your best resource will be your neurologist in trying to connect your actual symptoms/ the reason for the test with the MRI findings in trying to assign it to one of the above mentioned conditions.
