Condition: Mild Cognitive Impairment Due to Alzheimer's Disease · Subjective Cognitive Decline (SCD) · Sponsor: University Medicine Greifswald
This clinical trial investigates the effects of spermidine supplementation on sleep quality and sleep-dependent memory consolidation in older adults with Subjective Cognitive Decline (SCD) or Mild Cognitive Impairment (MCI), two populations at increased risk of future cognitive decline and dementia. Impaired sleep has been identified as a modifiable factor contributing to cognitive decline, and interventions targeting sleep architecture could offer therapeutic potential to prevent or slow down this decline. Spermidine is a naturally occurring polyamine found in foods such as wheat germ and soybeans. It induces autophagy, a cellular degradation and recycling process essential for neuronal maintenance and function. In animal studies, spermidine has been shown to improve memory performance, reduce neuroinflammation, and support mitochondrial health. Preliminary findings from human trials in individuals with SCD or MCI suggest potential cognitive benefits of spermidine, but results are not unequivocal, and the impact on sleep has not been systematically evaluated. In this randomized, double-blind, placebo-controlled trial, 76 participants aged 55 to 70 years with SCD or MCI will receive either spermidine (6 mg/day) or a placebo for 12 weeks. Sleep will be evaluated using overnight EEG in a controlled laboratory setting, focusing on measures such as slow-wave sleep and sleep spindle activity. Memory performance will be assessed before and after the intervention using standardize…
