Summary

Cognitive disorders include such things as memory disorders, mild cognitive impairment, and Alzheimer's disease (AD). The purpose of the study is to learn more about whether a dietary citicoline supplement will improve sleep and cognition. Sleep disturbances currently afflict approximately 25-44% of those with AD, resulting in decreased quality of life for those with AD and their caregivers and are a major driver of institutionalization.

Previous studies have tested this dietary supplement in Alzheimer's disease and shown that citicoline may improve cognitive decline. The research team would like to see if citicoline will also improve sleep. The citicoline that will be provided is made by Kyowa Hakko Pharma Chemical Company. This dietary supplement has been tested for Alzheimer's disease and found to be well tolerated. Citicoline has previously been used safely in other Alzheimer's disease populations at the same dosage.

Interventions

DIETARY_SUPPLEMENT

Citicoline supplement

Participants with AD will receive a dietary citicoline 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.

OTHER

Placebo

Participants with AD 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.
