Confirmed decline, missing history

Amara, 79, is confirmed by a home-care team to have marked decline in memory, language, and daily-task planning over the past year. No further history is available on how the decline began, whether any vascular events occurred, or any other diagnosis, and no family member could be reached for collateral history despite genuine attempts.
