About this study

Nutrition is an important modifiable risk factor of human cognitive health. Increasing data suggests that certain nutrients or food ingredients, such as plant polyphenols, have the potential to benefit cognitive abilities even in later life. In terms of polyphenols, Hydroxytyrosol (HT) has gained health benefit claims as a potential preventative antioxidant supplementation of neurodegenerative and amyloid-associated diseases while its pharmacological mechanisms suggest protection against cognitive decline. The primary objective of this study will be to evaluate the effects of HT-rich olive juice polyphenol supplementation alongside MeDi adherence compared with placebo alongside MeDi adherence in the prevention of cognitive decline among patients with Mild Cognitive Impairment associated with AD and non-AD pathology.
