As I said, the symptoms may return when under stress. Many will recover to a point that in normal situations, they are completely symptom free. Research has shown that the concussed brain will be more sensitive when under stress, be it traumatic, emotional, sensory, chemical, metabolic, or nutritional. That is why I recommend the vitamin and supplement regimen. It helps the brain tolerate stress.

The point is to live a life that attempts to reduce these stressors.
