Hi Christine, unfortunately a lot of these things seem vague. The neuro will be able to tell you more.
I take it you’re not diagnosed with MS?
Spots in the white matter can possibly be a sign of MS. They are usually called ‘lesions’ and it’s where the fatty matter around the nerves have broken down. That damage is what causes the symptoms in MS and is called demyelination.
Spots can be a sign of other stuff going on, but I think they will be looking at MS as one possibility amongst others.
Even after MRI they are not always sure as there isn’t one test for MS. They put your MRI results together with your symptoms and your symptom history. Even then they are not always sure and next step is to have a lumbar puncture to see if the immune system has been active in the Central Nervous System (CNS).
If it has, AND you have spots or marks on MRI, AND your symptoms match MS, then they can diagnose MS (the symptoms have to match the Macdonald Criteria. You can google that… It might be McDonald).
It can be a long drawn-out process. For me, it was over 2 years from seeing GP with symptoms to getting an MS diagnosis.
Hope this helps. Your neuro will be able to tell you more about what the MRI has shown.
