I found a few articles on gliosis, which appears to be an immune response to a possible head injury. What this means is that you immune system is causing inflammation and associated symptoms in your brain. It would be good to get a detailed explanation of your condition, symptoms, and treatment from the neurologist and other specialists. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9598641/#:~:text=Treatment%20with%20antioxidants%20or%20the,the%20hypothalamus%20of%20the%20brain. I have a few autoimmune diseases (I'm 70) and mostly treat them with diet, because mine are related to food intolerances (celiac, collagenous colitis, and I had a moderate TBI 33 years ago).
