Curcumin and neurodegenerative diseases: a perspective

Area of Science:

• Neuroscience
• Pharmacology
• Natural Products

Background:

• Curcumin, a polyphenol from turmeric, exhibits significant antioxidant and anti-inflammatory properties.
• It modulates key targets in chronic illness pathogenesis, showing potential for neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD).

Purpose of the Study:

• To review the health benefits, pharmacodynamics, and pharmacokinetics of curcumin.
• To highlight curcumin's neuroprotective effects, particularly in experimental models of AD and PD.
• To address curcumin's bioavailability, safety, and novel formulation developments.

Main Methods:

• Review of epidemiological evidence and scientific literature on curcumin's health benefits.
• Analysis of curcumin's antioxidant, anti-inflammatory, and molecular target modulation capabilities.
• Examination of pre-clinical data on neuroprotection in AD and PD models.

Main Results:

• Curcumin demonstrates therapeutic potential for neurodegenerative conditions through antioxidant, anti-inflammatory, and anti-protein aggregation activities.
• Pre-clinical studies support curcumin's neuroprotective effects in models of AD and PD.
• Bioavailability and formulation strategies are critical for enhancing therapeutic efficacy.

Conclusions:

• Curcumin shows promise for treating neurodegenerative diseases due to its multifaceted biological activities.
• Limited bioavailability and a lack of extensive clinical studies hinder its current therapeutic application for AD and PD.
• Significant research and development are required to establish curcumin as a viable neuroprotective agent.
