Alzheimer's sleep breakthrough? tiny study tests citicoline
NCT ID NCT05200208
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested whether a dietary supplement called citicoline could improve sleep and cognitive function in 20 people with Alzheimer's disease. Participants took either citicoline or a placebo for 3 months, and researchers measured sleep quality, daytime sleepiness, and thinking skills. The goal was to see if this well-tolerated supplement might ease common sleep problems in Alzheimer's and potentially boost memory and attention.

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 help Alzheimer's patients sleep better and think more clearly.
What could go wrong
This is a very small pilot study with only 20 people, so results may not apply to everyone. It's also too early to know if citicoline truly helps.
