Door-Through-Door Companion Rideshare Technology for Individuals With Alzheimer's Disease and Related Dementias (AD/ADRD)

The goal of this pilot randomized controlled trial is to assess the impact of D2D rideshare services with a trained companion driver on the rate of medical appointments for older adults and individuals with AD/ADRD. Participants will be assigned either door-through-door (D2D) rideshare or curb-to-curb (C2C) rideshare services. he main question it aims to answer is: Do D2D rideshare services reduce missed medical appointment rates compared to C2C rideshare services?
