(Source: Science Daily) -The mystery of exactly how consumption of extra virgin olive oil helps reduce the risk of Alzheimer's disease (AD) may lie in one component of olive oil that helps shuttle the abnormal AD proteins out of the brain.
Scientists once attributed it to the high concentration of healthful monounsaturated fats in olive oil -- consumed in large amounts in the Mediterranean diet. Newer research suggested that the actual protective agent might be a substance called oleocanthal, which has effects that protect nerve cells from the kind of damage that occurs in AD.

This highly useful study came to me via a poster on the Huffington Post.
Olive oil phenols and neuroprotection.
Abstract
Olive oil is a rich source of phenolic components which have a wide variety of beneficial health effects in vitro, in vivo, and clinically. The beneficial effects of olive oil phenols attributed to a variety of biological activities including free radical scavenging/antioxidant actions, anti-inflammatory effects, anti-carcinogenic properties, and anti-microbial activities. On the other hand, olive oil phenols have been shown to be some of neuroprotective effects against cerebral ischemia, spinal cord injury, Huntington's disease, Alzheimer's diseases, multiple sclerosis, Parkinson's disease, aging, and peripheral neuropathy. This paper summarizes current knowledge on the mechanisms of neuroprotective effects of olive oil phenols
