There is a growing body of research demonstrating the direct link between gastrointestinal inflammation and central nervous system inflammation. When the gut is inflamed, reactive and not functioning well, the brain may also present the symptoms of inflammation. Instead of stimulating a pain response, inflammation within the brain often gives rise to brain fog, anxiety, depression, irritability, cognitive and memory issues, crashing fatigue, mood swings, etc. For those with Post-Concussion Syndrome, reducing gastrointestinal inflammation and immune system reactivity can reduce systemic inflammation and, in turn, alleviate symptoms of inflammation within brain. Eliminating known food allergens, determining other dietary sources of immune reactivity and creating an anti-inflammatory diet plan can reduce systemic inflammation and promote brain balance and healing.
