Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Subjective Cognitive Decline (SCD) Dietary Supplement: Polyamine Dietary Supplement: Placebo Phase 2

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).

Outcome Measures
Go to

Primary Outcome Measures :
  1. Change in Memory performance from neuropsychological test [ Time Frame: change from baseline after 12 month (Prior to intervention (baseline T0) and after 12 months) ]
    Comparing memory function in subjects with polyamine intake and placebo treatment assessed prior to intervention (pre) vs. 12 month post intervention


Secondary Outcome Measures :
  1. Change in Cognitive Function (from extended neuropsychological test battery) [ Time Frame: change from baseline after 12 month ]
    Comparing cognitive function in subjects with polyamine intake and placebo treatment assessed prior to intervention (pre) vs. 12 month post intervention

  2. Change in polyamine concentration [ Time Frame: change from baseline after 12 month ]
    comparing polyamine concentration derived from blood plasma assessed prior to intervention (pre) vs. 12 month post intervention

  3. Change in inflammation [ Time Frame: change from baseline after 12 month ]
    comparing inflammation markers derived from blood plasma assessed prior to intervention (pre) vs. 12 month post intervention

  4. Change in Brain imaging biomarkers [ Time Frame: change from baseline after 12 month ]
    Multimodal analysis of biomarkers, regarding structural, functional, and perfusion-related plasticity, derived from magnet resonance imaging

  5. Change in Autophagy processes [ Time Frame: change from baseline after 12 month ]
    Evaluate autophagy processes through muscle biopsy assessed prior to intervention (pre) vs. 12 month post intervention

  6. Change in Autophagy processes [ Time Frame: change from baseline after 12 month ]
    Evaluate autophagy processes through blood parameters assessed prior to intervention (pre) vs. 12 month post intervention
