The findings showed that “cannabinoids work both to prevent inflammation and to protect the brain,” says researcher Maria de Ceballos in a news release. That “may set the stage for [cannabinoids’] use as a therapeutic approach for [Alzheimer’s disease].”

The cannabinoids completely prevented activation of cells that trigger inflammation. These cells gather near plaque and are believed to be involved in the development of Alzheimer’s disease.
