Citicoline supplementation enhanced verbal memory in older adults with less efficient memories. This suggests potential benefits for age-related cognitive decline and memory impairment.

Area of Science:

  • Neuroscience
  • Gerontology
  • Pharmacology

Background:

  • Age-related cognitive decline affects memory functioning in older adults.
  • Identifying interventions to support cognitive health in aging populations is crucial.

Purpose of the Study:

  • To evaluate the efficacy of citicoline in improving verbal memory in older volunteers.
  • To investigate the effects of citicoline on individuals with relatively inefficient memories.

Main Methods:

  • A randomized, double-blind, placebo-controlled study design was used.
  • Participants received either placebo or citicoline (1000 mg/d initially, then 2000 mg/d in a crossover phase).
  • Verbal memory was assessed using logical memory tests, with plasma choline levels also monitored.

Main Results:

  • Citicoline significantly improved delayed recall in subjects with inefficient memories in the initial study.
  • The higher dosage of citicoline in the crossover study demonstrated clear improvements in both immediate and delayed logical memory.

Conclusions:

  • Citicoline therapy is effective in enhancing verbal memory in older individuals experiencing memory inefficiencies.
  • Citicoline shows promise as a therapeutic agent for age-related cognitive decline and may help prevent dementia.
