anxious: I didn't find any patient stories about White Matter Disease specifically. Maybe you can.
So since MS is somewhat similar to you, you can try this one, "My MS Story - 17 Years Until a Diagnosis" He refers to many other patient stories. That vid will lead to many other vids. He also has decided to not take the recommended powerful drugs, as of yet.
I'm not saying that you have MS, I'm saying that what these people have to say might benefit you - and also make you feel less alone. Besides, videos can be easier to digest than written articles and scientific texts.
Here's one vid mentioning taking B6, which is also recommended BTW for various kinds of nerve danage.
Here's a very short one that mentions blood vessel **inflammation**, cholesterol, diabetes, smoking:
Here's a very technical one about comparing MRIs of MS on one hand, versus other white matter lesions that might get mistaken for MS:
It might only be helpful to see the rather long list of diseases there that can be mistaken for MS or vice versa. Lupus is one, and lupus is a famous inflammatory disease.
It's 11 minutes, but watch just the first two minutes to be convinced that this whole field is unclear.
The unclear confusion can go both ways, so roughly 18% of people diagnosed with MS actually have something different. This vid is technical, so I'll link only to the spot where she briefly describes immune system (aka inflammation) involvement: https://youtu.be/9LCkA1en3Jc?t=600
Here's one on diet, Paleo versus low saturated fat. My guess is you would do better on one or the other, it's not one-size-fits-all:
How's your blood pressure?
Well, you could get the feeling of motion sickness in a dream, and if so maybe it would be real enough to cause you to sweat. But if it happens again, ask your doctor.
Are you on a particular diet to improve the white-matter situation? A diet rich in vegetables, legumes, fruits, and olive oil and low in dairy, red meat, and processed meat is said to be good for white-matter issues.
