Brief Summary

Alzheimer's disease and related dementias (ADRD), including mild cognitive impairment (MCI), are becoming among the most prevalent causes of disability, death and healthcare costs worldwide. Sleep and circadian rhythm disturbances are common among individuals with MCI as well as their spouses/ partners and may increase risk of the development of ADRD in both patients and partners. This is the first study to systematically investigate sleep as a shared health behavior within couples in which one member has MCI, and the degree to which sleep and circadian disturbances impact both partners health and well-being, including cognitive decline and risk for ADRD.

Outcome Measures

Primary Outcomes (2)

  • Digit symbol: daily score

    This is a daily measure of attention and processing speed collected via smartphone. Participants will have 5 minutes to complete the items. In this measure, participants match each symbol presented to a number. The goal of the test is to complete the most items in the time allotted.

    This study will evaluate day to day change in digit symbol performance over 10 days.

  • Memory: daily score

    In this measure, participants will have the opportunity to learn a set of 18 words (30 seconds). These words will be present later in the assessment and participants are asked to recognize whether they are on the list.

    This study will evaluate day to day change in digit symbol performance over 10 days.

Secondary Outcomes (1)

  • Cogntive function: RBANS total score

    We will evaluate change from baseline to two years
