Reducing Cognitive Decline with Zinc: A Study on Memory and Executive Function Improvement

Abstract Summary

Objective: This study investigates the impact of zinc supplementation on cognitive function in older adults.

Context: Zinc is essential for brain health and cognitive function. This study aims to evaluate the effects of zinc supplementation on cognitive performance in older adults.

Methods Used

Approach: The study employs a randomized, double-blind, placebo-controlled trial. Participants aged 65 and above were divided into two groups, receiving either zinc supplements or a placebo for twelve months. Cognitive function was assessed.

Data Collection: Cognitive performance was measured using standardized neuropsychological tests at baseline, six months, and twelve months. Inflammation markers were evaluated through blood tests for CRP, IL-6, and TNF-α. The differences between the zinc and placebo groups were analyzed.

Researchers' Summary of Findings

Impact on Health: The research indicates that zinc supplementation is associated with improved cognitive function, including better scores on memory and executive function tests. Participants in the zinc group also showed reduced inflammation markers.

Health Implications: Regular zinc supplementation may support cognitive health by improving cognitive performance and reducing inflammation, potentially lowering the risk of cognitive decline in older adults.
