Sorry about your recent diagnosis, but glad that you introduced yourself. In the past couple of years, researchers are looking more at gray matter atrophy and MS, rather than simply monitoring white matter lesions. The specific areas they are focusing on are the thalamus, brain stem and third ventricle width. You might want to talk to your neuro and GP about this, and discuss ways to help your gray matter health. There are nutritional, exercise, alternative, and lifestyle strategies that have helped many. Keep learning, and all best wishes to you.
