Investigators aim to enroll approximately 40 individuals aged 18 -89 (inclusive) with either MCI or mild AD who will have Emerald deployed in their home for up to 12 weeks, spanning the time of approval of parent study screening and formal study enrollment. The Emerald device is a radio-wave sensor that uses signal processing and machine learning algorithms to track the gait, movement, respiration, and sleep of subjects without physical contact or effort by the user, i.e. it neither requires the subject to wear a sensor nor record any data. Emerald works by transmitting low-powered radio signals, 1000x less than Wi-Fi, that reflect off of the subject and return back to the device. If the user moves their arm or leg, or their chest expands and contracts from breathing, that movement changes how the signal reflects off of their body. Emerald records these reflections and processes them using algorithms that convert the radio signals into movement data, breathing rate, sleep stages (Awake, Light, Deep and REM), and key sleep parameters. The device will be deployed in the bedroom of each subject to capture behavior continuously.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '89 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Subjects will be recruited from the existing pool of study subjects for the parent study (MGB IRB protocol #2020P001652, ClinicalTrials.gov identifier NCT04430517).
