On November 8th, 2017, Miami Valley's Chapter of Alzheimer's Association hosted a Science Night called "Assessing Caregiver Stress and Burnout." For more details: https://alzdayton.wordpress.com/2017/09/25/science-night-assessing-caregiver-stress-and-burnout/
Motivation and Background
Alzheimer’s disease affects more than 5 million people claiming over 500,000 Americans annually . As the sixth leading cause of death in Americans , its management is challenging. Current reactive healthcare costs more than 17% of GDP in the US [3, 4]. Alzheimer’s related healthcare costs alone are around $150 billion a year to Medicare and Medicaid . To add to the challenge, dementia is an umbrella term that encompasses various forms of the disease such as Alzheimer’s disease, vascular dementia, and Huntington’s disease, to name a few . Not only are the healthcare costs associated with dementia staggering, but the impact on the caregivers is also a critical challenge; in 2013, 15.5 million family and friends provided 17.7 billion hours of unpaid care to those with Alzheimer's and other forms of dementia – care valued at $220.2 billion . With the exponential rise of the older population due to the baby boomers, the number of people with Alzheimer’s disease (the most prevalent form of dementia) is estimated to reach around 13.8 million [1,6]. This creates the strong need for unobtrusive sensing modalities that can help monitor people with dementia and support caregivers.
Dementia: Challenges and Opportunities
With increasing adoption of mobile devices and low-cost sensors, an unprecedented amount of data is being collected . However, in the context of dementia, it is challenging to convert this huge amount of data into actionable information that can: a) help detect behavioral changes in an individual with dementia and b) provide relevant information to the clinician supporting them in treating chronic illness. In our previous work, we derived actionable information from physical and physiological data collected from children diagnosed with asthma. We have developed kHealth kit [9, 28] a semantics-enabled smart mobile application with sensors, to capture observations from machine sensors (quantitative) and people (qualitative) in the domain of asthma . We also have active clinical collaborations to investigate and evaluate the use of kHealth technology for reducing readmission of GI (gastrointestinal) and ADHF (acute decompensated heart failure) patients after their discharge from the hospital.
CAST ( Caregiver Assessment Using Smart Gaming Technology)
The aim of this study is to detect changes in behavior (agitation, depression, and apathy, see here) and activity patterns of patients with dementia by using a combination of wearable and environmental sensors using a mobile platform. Detecting these behavior changes will result in a deeper understanding of the causes of mood and behavioral changes. This will involve detecting fluctuations in sleep patterns and evaluating the effects on stress using standard clinical methods. This can help predict mood events, which in turn can help alert clinicians for early intervention. The study will revolve around 10-20 dyads, each comprising a person with dementia (PwD) and his or her main caregiver (Cg). The person with dementia and caregiver must live in the same house or apartment. Sensors will be monitoring the sleep patterns of the patient as well as activity patterns using wearable sensors like the Jawbone UP24 to track parameters like number of steps, location, gait speed as well as wearable garments such as the Sensoria socks for an additional modality to measure gait parameters including speed, cadence, step count, etc. Environmental sensors like the Sense can be used to detect the activity trends. The data can be collected via Bluetooth and processed using an Android-based smartphone. Any abnormal changes in these patterns can then be validated using physical tests like TUG (obtained from the clinician), as well as cognitive tests like the Zarit Burden Interview (obtained from the caregiver). In addition, the effects of psychoactive medications for behavioral disturbances in patients will be associated with changes in their sleep and daily movements. This can provide long-term benefit to patients with dementia to monitor cognitive behavior as well as enable early intervention using ubiquitous sensors in an affordable and non-invasive manner.
