New findings indicate that endocannabinoids aid TBI recovery: When researchers boosted 2-AG levels shortly after injury, rats displayed less anxiety and less interest in alcohol.

This is significant since alcoholism is a serious comorbidity of brain injury. The researchers link the protective effect of 2-AG to changes in glutamate transmission in the central amygdala, the part of the brain that processes traumatic and fearful memories. Other preclinical research has demonstrated that endocannabinoids can play a protective role after traumatic brain injuries, like concussion, by ameliorating glutamatergic toxicity.
