Summary

The purpose of this research is to learn whether a dietary citicoline supplement will impact sleep and cognition. Cognitive disorders include such things as memory disorders and mild cognitive impairment. The investigators are studying persons with mild cognitive impairment (MCI). For this population, the team will assess whether citicoline also impacts biomarkers, a marker of the patient's biological state, in their body.

The investigators are interested in learning more about a dietary supplement called citicoline and how it helps sleep, cognition, and markers of Alzheimer's. Previous studies have evaluated this dietary supplement and shown that citicoline may impact cognitive decline. The investigator would like to evaluate if citicoline will also impact sleep and markers of Alzheimer's. This dietary supplement has been assessed in older adults and found to be well tolerated. Citicoline has been used safely in cognitive impairment populations at the same dosage.

Conditions

Interventions

DIETARY_SUPPLEMENT

Citicoline Supplement

Participants with MCI will receive dietary citicoline supplements. Subjective sleep measures will be measured via the Pittsburgh Sleep Quality Index (for measurement of sleep quality) and Epworth Sleepiness Scale (for measurement of sleepiness). Cognition will be measured by Rey Auditory Verbal Learning Test (RAVLT), Trail Making Test (TMT) Parts A \& B, and the Montreal Cognitive Assessment (MOCA). Participants will complete all questionnaires at baseline and at follow-up at 3 months. Participants will undergo a blood draw of approximately 20 ml at baseline and at follow-up.

OTHER

Placebo

Participants with MCI will receive a placebo supplement. Subjective sleep measures will be measured via the Pittsburgh Sleep Quality Index (for measurement of sleep quality) and Epworth Sleepiness Scale (for measurement of sleepiness). Cognition will be measured by Rey Auditory Verbal Learning Test (RAVLT), Trail Making Test (TMT) Parts A \& B, and the Montreal Cognitive Assessment (MOCA). Participants will complete all questionnaires at baseline and at follow-up at 3 months. Participants will undergo a blood draw of approximately 20 ml at baseline and at follow-up.
