It's rather complex. With the exact diagnosis and term, ask those website owners of they know of any support organisations. However, a number of things can also contribute to things, which might increase dysfunction. I'm not saying he will have any of these, but, of he does it could help. A lot of dysfunction comes along before it's permanent. The "broken glass" look in the MRI causes dysfunction before it gets more permanent. Stopping that just might help a lot. With me it restored significant dysfunction but I had additional issues, that treated, helped me from forgetting everything all the time, and brought up my cognitive function again.

Here are some other things that affect white matter or memory

- Genetic and age related problems dealing with, or recycling (genetic, active form of the vitamin), the vitamin b12. The genetic problem is unlikely, but older people have an issue absorbing B12. But, if the problem is recycling B12 to its activd methylated form, taking B12 won't get checked converted to the active form.

- pyrolia. This is a condition where a component of the blood binds to zinc and takes it out the body. There are three of do different nutrients involved. Zinc at the wriong dosage is neurotic, so find a health practitioner competent in this is important.

- ME/Chronic Fatigue is associated with demyelination. A health care provider that specislises in treatment. Research indicates part viral cells in cells affecting cellular waste clearing and mitochondrial ATP energy production. There are a series of nutrients that help too. ME is associated with nutrient malabsorption and gut issues. Store bought probiotic tablets tend not to be very week compared to natural fermented foods.

- Autism Spectrum Disorder is associated with demyelination. A health care provider that specislises in treatment. There are a series of nutrients that help too. It is associated with nutrient malabsorption too, and gut issues. Store bought probiotic tablets tend not to be very week compared to natural fermented foods. Digestive enzymes is something else a health professional may cover.

- Lyme's/tick born disease (associated with white matter disease from pathogen from ticks or other insects. If so, see a descent Lyme's specialist. Who might put one onto one of the two salt and vitamin C protocols).

-parasites. Some people affected more, and older people. Harbour pathogens, changing the biochemistry of the body, and modern research indicates strong links with various diseases, and some mental illnesses. This is only a very early feild, that practitioners haven't been educated in (it can take a decade or more for practitioners to catch up with research in general practice).

Not many are competent with the last two above, lack insight into the deep complexities, and imagine things instead.

A these things require health care practitioners competent in them. A lot of misconceptions and outdated understandings, exists with them. So, a good practitioner, who has taken time to investigate these things, in order to properly treat them to the utmost efficacy, is desirable. There are a number out there, who just want to push an opinion.
