Summary

This completed pilot study from Emory University tested whether a daily citicoline supplement could improve sleep quality, daytime sleepiness, and memory in 100 older adults with mild cognitive impairment (MCI). Participants took 1000 mg of citicoline for 3 months and completed sleep questionnaires, cognitive tests, and blood or spinal fluid tests to measure Alzheimer's-related biomarkers. The goal was to see if this well-tolerated supplement might help both sleep and early signs of Alzheimer's disease.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

citicoline (dietary supplement)

What this could lead to

If it works, this could point toward a simple supplement to improve sleep and slow cognitive decline in people with mild memory problems.

What could go wrong

This is a small, early pilot study with no placebo group, so results may not be reliable. The supplement may have no real effect on sleep or Alzheimer's markers.
