Abstract

Emerging evidence suggests that extra virgin olive oil (EVOO) polyphenols may play a role in neuroprotection against neurodegenerative diseases.

EVOO is rich in polyphenolic compounds such as hydroxytyrosol, oleuropein, tyrosol, and oleocanthal.
These compounds exhibit antioxidant, anti-inflammatory, and neuroprotective properties.
EVOO polyphenols may help reduce oxidative stress and inhibit abnormal protein aggregation.
There is potential for EVOO to regulate neuroinflammation associated with neurodegenerative diseases.
Incorporating EVOO into dietary and medical interventions could help mitigate disease progression.

Neurodegenerative diseases such as Alzheimer's, Parkinson's, ALS, and Huntington's disease pose a growing global health challenge due to their prevalence in aging populations and their devastating impact on cognitive and motor functions. Current treatments focus on symptom management, with no options available to reverse neuronal damage. Emerging evidence highlights the potential role of extra virgin olive oil (EVOO) polyphenols in neuroprotection, particularly in the context of the Mediterranean diet, which is associated with lower rates of neurodegenerative disorders. EVOO's rich polyphenolic compounds, including hydroxytyrosol, oleuropein, tyrosol, and oleocanthal, exhibit potent antioxidant, anti-inflammatory, and neuroprotective properties. These bioactive molecules have shown potential in modulating disease-specific pathways, such as reducing oxidative stress, inhibiting abnormal protein aggregation, and regulating neuroinflammation. This paper explores the therapeutic potential of olive oil polyphenols for neurodegenerative diseases, detailing their mechanisms of action across different conditions. Our findings suggest that incorporating EVOO into dietary and medical interventions could serve as a promising strategy for mitigating neurodegenerative disease progression and enhancing cognitive health.
