 CBD reduces plaque and improves cognition in model of familiar Alzheimer's. A two-week course of cannabidiol, or CBD, helps normalize and restore the function of two proteins associated with reducing amyloid-beta accumulation in mouse models of familial Alzheimer's disease. CBD also reduces levels of IL-6, an immune protein associated with inflammation of Alzheimer's patients. Researchers gave CBD to a mouse model of Alzheimer's and then used behavioral tests and immunoassays to evaluate cognitive and motor performance of the mice. The researchers report that the treatment, quote, enhanced IL-33 and TREM2 expression, ameliorated the symptoms of AD and retarded cognitive decline, end quote. The behavior of the mice also improved following the treatment.
