Researchers Move In on Role of Brain's Naturally Occurring Marijuana - Researchers have discovered that cannabinoid acts, at least in part, in a region of the brain that plays a key role in learning and memory. The factors responsible for cognitive decline are neuronal loss, changes in brain physiology, and increased rates of disease and injury.

MCI is characterized by a decline in memory function, as compared to patients with early Alzheimer's Disease, who tend to demonstrate impairments in multiple cognitive areas.
