Outcome Measures

Primary Outcomes (1)

  • Change in Memory performance from neuropsychological test

    Comparing memory function in subjects with polyamine intake and placebo treatment assessed prior to intervention (pre) vs. 12 month post intervention

    change from baseline after 12 month (Prior to intervention (baseline T0) and after 12 months)

Secondary Outcomes (6)

  • Change in Cognitive Function (from extended neuropsychological test battery)

    change from baseline after 12 month

  • Change in polyamine concentration

    change from baseline after 12 month

  • Change in inflammation

    change from baseline after 12 month

  • Change in Brain imaging biomarkers

    change from baseline after 12 month

  • Change in Autophagy processes
