Hello @nsainato, anytime we get results from a medical scan or blood tests that we don’t understand it can be alarming. I’ve had several MRIs over the past year and was told some of the changes in white matter are normal and expected as we age.
The best answers would come from your neurologist or physician, whomever ordered the MRI.

May I ask what led your physician to schedule an MRI for you? Were you having symptoms such as headaches, dizziness or vision issues?
