Early diagnosis lowers family costs and keeps more treatment and planning options open. This checklist helps adult children act quickly after memory, thinking, or money problems appear. Mild cognitive impairment means clear memory change that does not yet block daily life.
The NIA-funded U.S. Cost of Dementia Project puts total U.S. dementia costs at $818 billion in 2026, according to the USC Schaeffer Center in its 2026 cost study.

Why does timing change the cost?
Earlier action shortens the hardest phase. NIA-supported modeling finds early anti-amyloid treatment cuts time with severe dementia by 1.2 years, from 3.7 years to about two-thirds, according to the USC Schaeffer Center in its early-treatment analysis.
That shorter severe phase is worth almost $140,000 per patient in societal benefit. Families feel this as fewer months of round-the-clock care, lost work, and paid support.
Why do families carry most of the bill?
About 80 percent of the $818 billion falls on families through unpaid care, forgone earnings, out-of-pocket costs, and lost quality of life. Unpaid care alone is $237 billion, plus $23 billion in forgone earnings by patients and care partners.
That means the health system pays only part of the total. Adult children often supply the time, income loss, travel, and home help.
Who can receive the new Alzheimer's drugs?
The FDA-approved drugs lecanemab and donanemab are only for early symptomatic Alzheimer's. Patients need mild cognitive impairment or mild dementia with confirmed amyloid.
Later-stage patients cannot receive them. A documented early diagnosis therefore decides whether these options stay open.
Why do so many early cases get missed?
Primary-care doctors detected only about 8 percent of expected mild cognitive impairment cases, according to USC researchers in their MCI detection report. About 7 million Americans remain undiagnosed even though MCI progresses to dementia at 10-15 percent yearly.
Money trouble can appear first. People who later developed dementia were more likely to miss bill payments starting 6 years before diagnosis, according to NIH researchers in their financial warning-signs report. Credit scores fell below 620 starting 2.5 years before in adults 65 and older living alone.
What should adult children do this month?
Ask for a cognitive check if memory lapses, bill trouble, or personality change persist. Bring a short log with dates, missed payments, driving concerns, and medication errors. Call the parent's primary-care office this week and ask how to share observations before the visit.
- Request MCI screening, hearing and vision checks, medication review, and amyloid testing rules
- List all accounts, autopay status, late notices, and new helpers or callers
- Ask who can join visits, handle paperwork, and provide backup care
- Set one follow-up date for test results and next decisions
