This study is evaluating cognitive function in older adults that are undergoing surgery using remote assessments. Participants complete a battery of neuropsychological assessments prior to their surgery date. The battery includes smartphone adaptions of tests of thinking, memory, speech, and movement. The participant has a one-hour remote visit, where the investigators will conduct a Montreal Cognitive Assessment (MoCA) and have the participant complete the smartphone assessments. After their surgery, participants are evaluated on the delirium rating scale.
