Polyamine-enriched Diet in Elderly Individuals With Subjective Cognitive Decline (SmartAge)

April 22, 2021 updated by: Claudia Schwarz, Charite University, Berlin, Germany

Effect of Polyamine-enriched Dietary Supplementation on Cognitive Function and Biomarkers in Elderly Individuals With Subjective Cognitive Decline

The overall objective of this study is to examine the effect of polyamine supplementation on cognitive performance and further characterization of individuals with subjective cognitive decline.

Study Overview

Detailed Description

Memory abilities are known to decline during aging, a process that is accelerated in pathological conditions like mild cognitive impairment (MCI) and Alzheimer's disease (AD), all of which are a growing public-health concern with devastating social and economical effects. Polyamines supplementation and corresponding up-regulation of autophagy (i.e., cellular protein degradation pathways) may be a key target of intervention against age-related memory decline. The study will investigate whether a polyamine-enriched dietary supplementation (through capsule intake) could provide positive effects on cognitive function and biomarkers of elderly individuals (60-90 years old) with subjective cognitive decline (SCD).
