Intelligent Systems For Assessing Aging Changes: home-based, unobtrusive, and continuous assessment of aging.

Objectives: To describe a longitudinal community cohort study, Intelligent Systems for Assessing Aging Changes, that has deployed an unobtrusive home-based assessment platform in many seniors homes in the existing community.

Methods: Several types of sensors have been installed in the homes of 265 elderly persons for an average of 33 months. Metrics assessed by the sensors include total daily activity, time out of home, and walking speed.

Unobtrusive assessment of activity patterns associated with mild cognitive impairment.

Background: Timely detection of early cognitive impairment is difficult. Measures taken in the clinic reflect a single snapshot of performance that might be confounded by the increased variability typical in aging and disease. We evaluated the use of continuous, long-term, and unobtrusive in-home monitoring to assess neurologic function in healthy and cognitively impaired elders.

Patterns of dietary supplement usage in demographically diverse older people.

Objective: To analyze dietary supplement usage data from 494 older adults, aged 65 to 101 years.

Setting: Community dwellers living independently of institutionalized care.

Design: All dietary supplements, including botanicals, were recorded to aid in assessing the health status of older adults.
