A cognitive screen is a short office test — a few minutes of recall, drawing and orientation — and a low score is a reason to schedule a full evaluation, not a reason to tour assisted living. What actually decides a care setting is the functional assessment that follows: how much help the person needs with bathing, medications, meals and money, plus a separate driving judgment and a hard look at what the options cost. The gap between those two things is where families lose money and autonomy they did not have to give up. A treatable cause can look exactly like early dementia, and new Medicare-funded dementia support can hold a household together at home longer than most families expect.

A screen score is a starting point, not a verdict
The U.S. Preventive Services Task Force reviewed cognitive screening and issued an "I" statement — meaning the evidence is insufficient to weigh the benefits and harms of screening everyone 65 and older who has no symptoms. That is the finding in the Task Force's February 2020 recommendation on cognitive impairment screening. A number on a screening form does not name a disease and does not name a care setting.
What it does is trigger an evaluation. The Alzheimer's Association's 2025 DETeCD-ADRD guideline directs clinicians through a tiered workup that produces three separate findings: whether the person has mild cognitive impairment or dementia, which cognitive-behavioral syndrome fits, and which underlying disease is the likely cause. The guideline also calls for validated instruments measuring both instrumental and basic activities of daily living. Ask the clinician which of those three questions has been answered. If the answer is "we did a screen," the evaluation has not happened yet.
Rule out the reversible causes first
Several conditions produce cognitive symptoms that resolve with treatment. The National Institute on Aging's guidance on assessing cognitive impairment in older patients lists medication side effects, metabolic and endocrine problems such as thyroid disease and B12 deficiency, delirium from an infection like a UTI, and depression among the causes to consider. This is the single strongest argument for not moving anyone quickly.
A urinary tract infection can cause sudden confusion in an older adult that reads, to family, as dementia arriving overnight. Treating the infection can return the person to baseline. A move made during that window is expensive, disorienting, and hard to undo. Practical step: bring every bottle — prescriptions, over-the-counter drugs, supplements — to the evaluation appointment, and ask specifically whether bloodwork covered thyroid function and B12, and whether depression was assessed.
Function, not the test score, points to a setting
The level of assistance a person needs with daily tasks is what distinguishes independent living, assisted living and nursing-home care. The Alzheimer's Association's companion paper on validated functional assessment instruments covers both instrumental activities — managing medications, finances, meals, transportation — and basic ones like bathing and dressing. Two people with the same screen score can need completely different arrangements.
One still pays bills on time and cooks, but forgets names; the other has stopped opening mail and is skipping doses. The second person needs help, and the help needed is specific enough to shop for. Things worth documenting before any tour: Bring that list to a discharge planner, geriatric care manager or the assisted-living intake staff. It is a far better basis for a conversation than a diagnosis label.
- Medications: taken correctly without prompting, with a pillbox, or only when someone hands them over
- Money: bills paid on time, unopened mail, unusual purchases, susceptibility to phone or mail scams
- Meals: cooking, reheating, or not eating regularly
- Bathing and dressing: independent, needs reminding, or needs hands-on help
- Nights: sleeping through, or wandering and calling
Driving is its own assessment
Mild impairment does not automatically end driving, and treating it as automatic costs people independence they could keep. The American Academy of Neurology's 2010 practice parameter gives the Clinical Dementia Rating scale — a staged rating of severity — its strongest evidence rating, Level A, for identifying drivers at increased risk, with CDR greater than 1 indicating high risk. The practice parameter also reports that between 41% and 85% of people rated CDR 0.5 to 1 passed on-road driving tests. In that mild range, the AAN points to weaker but usable signals.
A caregiver who rates the person's driving as marginal or unsafe carries Level B evidence. Crash and citation history carries Level B. Reduced mileage, avoiding highways, night or bad weather, and an impulsive or aggressive personality style are Level C. The neutral tiebreaker is an on-road evaluation, usually by a driver rehabilitation specialist. It gives the family an outside judgment and takes the decision out of the household argument.
Price the options before you commit to one
CareScout's 2025 Cost of Care Survey, with data collected from July through November 2025, put the national median for assisted living at $74,400 a year and a semi-private nursing-home room at $315 a day — $114,975 annually. Those figures come from the survey release and are medians, so local costs run above and below them. Medicare does not close that gap.
Medicare.gov states plainly that Medicare does not cover long-term or custodial care — help with activities of daily living — and does not cover room and board in assisted living. It continues to cover medical services delivered to someone living there, which is a narrower thing than families often assume when they hear "Medicare covers it." Run the arithmetic against actual assets before touring. The difference between a supported year at home and a year of assisted living is often the deciding number, not the clinical picture.
Check GUIDE before you move anyone
CMS launched the Guiding an Improved Dementia Experience model on July 1, 2024, an eight-year test of comprehensive dementia care. Under the model, participating organizations are paid to provide care navigation, a 24/7 support line, caregiver training and respite care. About 400 organizations take part, including 294 that began on July 1, 2025.
Respite and a reachable support line address the two pressures that most often force a move: the caregiver reaching exhaustion, and nobody knowing who to call at 2 a.m. Support of that kind can defer a placement rather than replace it. Ask the evaluating clinician whether the practice participates in GUIDE, or whether a nearby health system does. Make that call in the same week as the evaluation, before the family starts scheduling tours.
Frequently Asked Questions
The evaluation found mild cognitive impairment, not dementia. Does that mean assisted living?
Not by itself. The Alzheimer's Association guideline treats cognitive-functional status and functional ability as separate findings, and it is the assistance needed with medications, finances, meals and bathing that maps to a setting.
Can we require an on-road driving test?
A family cannot compel one, but a physician can refer for it, and in many states a physician or family member can report an unsafe driver to the licensing agency. The AAN notes that most people at CDR 0.5 to 1 pass such tests, so the referral often preserves driving rather than ending it.
Will Medicare pay for a memory care unit?
No. Medicare.gov states it does not cover custodial care or assisted-living room and board, though medical services delivered to a resident remain covered.
