Intracranial Arteriosclerosis

There are currently 6.7 million Americans living with dementia and, without significant breakthroughs, this figure will double to 12.7 million by 2050. There are about 46,000 long-term care (LTC) facilities in the U.S. More than half of LTC residents have some form of dementia (Alzheimer's Association, 2018). Responsive behaviors and dysfunction of the dementia care triad-i.e., the PLWD, professional Care Partner (CP), and Family Member (FM)-are inexorably linked. The emergence of responsive behaviors can lead to disruption of the triad's function. Thus, it is imperative to maintain positive relationships and a high quality of life (QoL) within the triad to reduce BPSD. Cognitive Stimulation Therapy (CST) has demonstrated improvements in QoL and relationships for PLWD. CST is a psychosocial intervention that promotes communication and engagement in PLWD via a structured program of meaningful and enjoyable theme. While clinical trials have shown improvement in cognition and QoL, the potential large-scale impact of CST has been hampered by low adherence, with less than 40% completing trials. One likely reason for the low adherence to CST is the reliance on generic and non-digital tools (e.g., paper-based agendas, tools, DVDs, and board games) in facilitating the intervention. That is, even though CST aims to be personalized, the specific interventions used in the field tend to be generic and not tailored to each PLWD's specific interests. The use of digital technology to implement CST would offer considerable advantages to expand and personalize the range of stimulation content and provide a means for monitoring responses, optimizing protocols, and promoting adherence.
The proposed Phase II study will involve the continued development and evaluation of a multi-faceted software platform called "Building Relationships using Artificial Intelligence and Nostalgia" or BRAIN. The BRAIN Platform will be the first-ever Artificial Intelligence (AI) powered CST digital therapy platform for PLWD. The platform, which has been shown to be effective in an initial Phase I clinical trial, has three main goals: to improve the quality of life of PLWD, to reduce BPSD in PLWD, and to foster positive relationships between members of the care triad. The proposed Phase II project has the following Specific Aims: 1. Create an improved Beta version of the BRAIN Platform's eight components: (1) the Admin Management Dashboard, (2) the Annotation Dashboard, (3) the Log Viewer, (4) the Content Management System (CMS), (5) the Private CMS, (6) the Control App, (7) the Home App, and (8) the Training Dashboard. 2. Fine-tune the different classes of AI algorithms-i.e., behavioral analytics, personalized content recommendation, and personalized program generation-in the BRAIN app such that they can (a) recognize and track 12 distinct behaviors and indicators of PLWD, (b) use these behavioral traits as a basis for automatically rating the relative success of each activity, and (c) automatically recommend personalized activities that are likely to be successful for individual PLWD. 3. Conduct a Cluster Randomized Trial (CRT) of the BRAIN App to examine the app's impact on engagement/affect, quality of life, and responsive behaviors. 4. Examine satisfaction and ease of use of the app for PLWD, LTC staff, and FMs.

Healthcare systems around the world, including within the United States, have long-established shortages of trained caregivers. The American Health Care Association states that "the health care system has experienced a shortage of trained caregivers for critical roles for some time." This scarcity directly impacts the 45,800 Long-Term Care (LTC) communities throughout the U.S.
Concurrent with this staff shortage, more than half of LTC residents have some form of dementia. These two issues create a serious public health concern, since dementia is associated with a variety of behavioral expressions, such as aggression, anxiety, and agitation. Behavioral expressions of dementia can be successfully managed with the use of tailored, psychosocial interventions and communication support. Unfortunately, existing staff shortages make the facilitation of such interventions challenging.
One powerful and often-overlooked approach to ameliorating staffing shortages involves the utilization of retired volunteers to facilitate interventions for persons with dementia (PWD). Based on the nearly universal love of music and a promising pilot study, the product to be developed and tested in this STTR will build upon the combined prior work of the Principal Investigators. Making Connections Thru Music (MCTM), an urgently needed product, will enable retired volunteers to facilitate an evidence-based music and discussion intervention with PWD. MCTM aims to improve engagement, enhance quality of life, and reduce behavioral expressions in PWD. The intervention will consist of two main components: (1) a comprehensive online training course for volunteers, which will provide a general overview of dementia, demonstrate effective communication strategies to use with PWD, and instruct volunteers to effectively facilitate MCTM sessions, and (2) an app containing a structured MCTM intervention protocol and toolkit, which will be the means by which volunteers facilitate MCTM. MCTM will be marketed to LTC communities.
