my husband received massive radiation and chemotherapy wafers for a malignant brain tumor. Now, the radiation has caused massive necrosis (build-up of dead tissue) in his brain. The tumor is gone but he is suffering major memory loss,confusion, fatigue, loss of quality of life in general, etc. due to this problem. They tell us there is no treatment for it other than a blood thinner and that nobody is really researching the problem. Does anyone know of any alternatives we might have to help him? He is only 32.
