Extra virgin olive oil protects memory and helps prevent Alzheimer's

Prevent dementia Experts have revealed extra-virgin olive oil could help protect against dementia

Alzheimer's Research UK agrees that more tests will have to be carried out before it can be stated that olive oil could have similar benefits in people. This proves that olive oil can help your mind work better, which in turn might indicate that it could potentially prevent Alzheimer's disease.

A study published Wednesday said consuming extra-virgin olive oil could reduce the chances of suffering from Alzheimer's disease. These two are the classic hallmarks or Alzheimer's disease.

Researchers divided the rodents into two groups, one that received a diet enriched with extra-virgin olive oil and one on a regular diet without it. Due to the activation of autophagy was preserved memory and synaptic integrity, and pathologic effects in animals otherwise destined for the development of Alzheimer's disease, was significantly reduced.

"This is an exciting finding for us", said Domenico Praticò, MD, Professor in the Departments of Pharmacology and Microbiology and the Center for Translational Medicine at LKSOM and senior author of the study, in a press release.

Previous research had already linked extra virgin olive oil to numerous health benefits of the Mediterranean diet.

While recent studies have found that the phenolic compounds and antioxidant qualities of EVOO can protect against both disease-related and age-associated brain oxidation in mice, these studies only addressed one of the main characteristics of the Alzheimer's disease phenotype. Autophagy is the process by which cells break down and clear out debris and toxins that accumulate between cells.

But new research moves closer to a prevention - and potentially reversing - strategy, by studying the effects of extra-virgin olive oil on the cognitive performance and brain health of mice.

The olive oil was given to the mice when they were only six months old and before any symptoms of Alzheimer's set in. These include the working memory, spatial memory and learning skills.

"Usually when a patient sees a doctor for suspected symptoms of dementia, the disease is already present", Praticò added.

"Brain cells from mice fed diets enriched with extra- virgin olive oil had higher levels of autophagy and reduced levels of amyloid plaques and phosphorylated tau", Pratico said.

He said there has already been evidence that people who eat Mediterranean diet have lower risks of developing dementia when they grow old.

"Further studies will need to explore the reported effects of extra-virgin olive oil before we could say that it holds specific health benefits beyond those of any other component of a healthy diet".

Consumption of extra-virgin olive oil reduces the risk of dementia, inflammation of the brain and Alzheimer, according to a new study.
