Alzheimer's Disease and Related Dementias

This study aims to evaluate the efficacy of community-based early detection and targeted interventions, including stem cell therapy and wearable non-invasive brain-computer interface (BCI) devices, for Mild Cognitive Impairment (MCI) in adults aged 55 years and older residing in U.S. urban and suburban communities. Primary objectives include assessing improvements in MCI detection rates, cognitive outcomes, and progression delay compared to standard care.

Dementia is the most expensive medical condition in the US and increases in prevalence with age. More than 5 million Americans have Alzheimer's disease, the most common form of dementia. Mild cognitive impairment is a transitional stage between normal cognitive aging and Alzheimer's disease or another type of dementia, and is indicative of higher risk for dementia. In addition to the obvious health and quality-of-life ramifications of dementia, there are high direct (e.g., subsidizing residential care needs) and indirect (e.g., lost productivity of family caregivers) economic costs. Implementing interventions to prevent MCI and dementia among older adults is of critical importance to health and maintained quality-of-life for millions of Americans. Recent data analyses from the Advanced Cognitive Training in Vital Elderly study (ACTIVE) indicate that a specific cognitive intervention, speed of processing training (SPT), significantly delays the incidence of cognitive impairment across 10 years. The primary contribution of the proposed research will be the determination of whether this cognitive training technique successfully delays the onset of clinically defined MCI or dementia across three years.

Older sexual and gender minority (SGM) patients are at risk for receiving inequitable end-of-life care; those with Alzheimer's disease and related dementias (ADRD) are at particularly high risk. Failure to collect and integrate sexual orientation and gender identity (SOGI) data to identify patients' informal support systems may have adverse health consequences for SGM older adults, particularly for those dependent on informal caregivers to provide in-home support and assist with activities of daily living. The goal of this K01 is develop a novel training for hospice staff in person-centered communication that includes SOGI data collection to promote authentic end-of-life care for SGM patients and their caregivers.
