This study shows how important it is to rule out gluten and dairy sensitivity in the face of brain or nerve impairment. Testing should be thorough and look at the different immune-reactive portions of both gluten and dairy. Even better is to find out whether you react to these foods before neurological symptoms present. You can have neurological inflammation and autoimmunity for years or decades before it becomes obvious. At that point, damage may be significant and permanent, although dietary intervention can still have a profound impact.
