Extra-virgin olive oil ‘can protect brain against Alzheimer’s’

22nd June 2017

A new study has demonstrated the potential benefits that extra-virgin olive oil can deliver in protecting the brain against Alzheimer's disease.

Conducted by the Lewis Katz School of Medicine at Temple University, the research offered evidence that consuming extra-virgin olive oil protects memory and learning ability, while reducing the formation of amyloid-beta plaques and neurofibrillary tangles in the brain, which are established markers of Alzheimer's.

Olive oil was introduced into the diet of mice before symptoms of Alzheimer's disease began to emerge, with those on the olive oil-enriched diet performing significantly better on tests designed to evaluate working memory, spatial memory and learning abilities.

Studies of brain tissue from both groups of mice, meanwhile, demonstrated dramatic differences in nerve cell appearance and function.

Further research will now be conducted to see whether extra-virgin olive oil can deliver similar benefits for mice that have already developed plaques and tangles.

Dr Domenico Pratico, a professor at the departments of pharmacology and microbiology at the Lewis Katz School of Medicine at Temple University, said: "Usually when a patient sees a doctor for suspected symptoms of dementia, the disease is already present. We want to know whether olive oil added at a later time point in the diet can stop or reverse the disease."
