In March 2021, researchers from the Augusta Georgia Dental College of Georgia conducted a 2-week study with positive results. For the first time in history, they were able to demonstrate that CBD is beneficial in normalizing the level and function of the TREM2 and IL-33 proteins, which are vital in helping the immune systems of the brain eat off dead cells as well as other plaque that builds up in patients with Alzheimer’s. In addition, they found that CBD reduces IL-6 levels, an immune protein that has been linked to high inflammation among patients with this condition, says Dr. Babak Baban, a corresponding author of the study and an immunologist as well as an associate dean for research.
