Pilot Study About Extra Virgin Olive Oil "Coratina" in Mild Cognitive Impairment and Alzheimer's Disease Patients

2020-01-22 12:13:01 | BioPortfolio


Alzheimer's Disease is a neurodegenerative disease age related caused by neurofibrillary tangles misfolding and Beta-amyloid protein accumulation. In the last decade several findings showed the role of biophenols present in diary intake such as extra virgin olive oil as potential antagonist of neurodegeneration. Two population studies (The Seven Countries Study and Three-City-Study) and four clinical trials (PREDIMED, PREDIMED - NAVARRA, ACTRIN and ISRCTN) have already suggested that mediterranean diet or other diets supplemented with extra virgin olive oil could improve cerebral performance.


24 MCI or Alzheimer's Disease patients will be recruited and randomised; 12 of them will receive extra virgin olive oil "coratina" (EVOO-C); 12 of them will receive biophenol low dose olive oil (ROO). Each patient will consume a total amount of 10 mg olive oil in a year (12 months). Clinical assessement will be based on:

- neurological examination (T0, T6, T12);

- cardiological examination (T0, T12): a supra-aortic vessels and brachial artery ecocolordoppler will be performed;

- ophthalmological evaluation (T0, T12): a optic coherence tomography will be performed;

- neuropsychological assessment (T0, T12);

- nutritional assessement(T0, T3, T6, T9, T12).

Each subject will perform:

- brain MRI (T0, T12);

- Beta Amyloid Positron Emission Tomography (T0, T12) A lumbar puncture will be ruled as well (T0) and markers of neurodegeneration (Beta-amyloid 1 - 42, total tau protein, fosfo-tau, Brain Derived Neurotrophic Factor (BDNF), Neurofilament (NFL) will be quantified); Renal, hepatic and nutritional status will be assessed 3 times in 12 months (T0, T6, T12).

Medical and Biotech [MESH] Definitions

Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS. DYSKINESIAS (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. Common etiologies include CEREBROVASCULAR DISORDERS; NEURODEGENERATIVE DISEASES; and CRANIOCEREBRAL TRAUMA.

A group of severe neurodegenerative diseases characterized by intracellular accumulation of autofluorescent wax-like lipid materials (CEROID; LIPOFUSCIN) in neurons. There are several subtypes based on mutations of the various genes, time of disease onset, and severity of the neurological defects such as progressive DEMENTIA; SEIZURES; and visual failure.
