Hello Mareblu and Welcome!
If you have you 'MRI' report you will be able to read what the findings are, like whether the white matter is consistent with 'demyelinating disease' or 'small vessel ischemic changes' which would be more likely with stroke.
You need a neurologist to decipher.
I had a series of small strokes a few years back. It turned out that I have a clotting disorder called the 'antiphospholipid syndrom.'
I hope you find your answers soon! Take care.
