For most adults over 65, cognitive screenings should happen annually — roughly as often as a routine physical exam. That’s the general consensus among geriatric health organizations, which recommend yearly assessments beginning at age 65 for adults without notable symptoms or risk factors. For those at higher risk — including people with a family history of dementia, cardiovascular disease, or who have noticed changes in memory or thinking — screenings every six to twelve months are more appropriate. For lower-risk individuals with strong baseline results, every one to three years may be sufficient.
To put this in practical terms: a 67-year-old woman with well-controlled blood pressure, no family history of dementia, and no subjective memory complaints might reasonably have a cognitive screening every two years. Her neighbor of the same age, whose father had Alzheimer’s and who has mentioned forgetting words during conversation, should be assessed every six to twelve months. The difference is not about fear — it’s about matching the frequency of monitoring to the level of individual risk. This article covers how those recommendations are set, what Medicare covers, what the major medical bodies actually say, and how newer tools like blood-based biomarkers are beginning to change the picture.

What Is the Recommended Frequency for Cognitive Screenings in Older Adults?
The most widely cited starting point is annual screening beginning at age 65. Geriatric health organizations frame this as a reasonable baseline for routine cognitive monitoring, covering key domains such as memory, executive function, attention, language processing, and visuospatial skills. The annual rhythm aligns with other preventive care touchpoints, which makes it easier for both clinicians and patients to build it into a regular health maintenance routine. However, “annual” is a default, not a ceiling.
For adults with identifiable risk factors — cardiovascular disease, diabetes, a first-degree relative with Alzheimer’s, or a personal history of mild cognitive impairment — the recommendation shifts toward every six to twelve months. This more frequent monitoring allows clinicians to catch changes in trajectory early, before functional decline reaches a point where intervention options are more limited. On the other end of the spectrum, adults who are younger than 70, have no known risk factors, and have a strong cognitive baseline from a previous assessment may be appropriately screened every one to three years. The takeaway is that there is no single correct answer for everyone. Age 65 is a useful threshold for beginning, but after that, frequency should be driven by the individual’s clinical picture, not by calendar alone.
What Does the USPSTF Actually Say — and Why Does It Matter?
The U.S. Preventive Services Task Force, the body that issues evidence-based recommendations for preventive care in primary care settings, has taken a notably cautious position on universal cognitive screening. The USPSTF currently states there is insufficient evidence to recommend for or against routine cognitive screening in asymptomatic older adults — meaning those who have not reported any symptoms and show no outward signs of decline. This position is also reflected in a recommendation statement published in JAMA. This does not mean the USPSTF discourages cognitive screening.
It means the evidence is not strong enough, in their assessment, to recommend universal screening as a standard practice for every asymptomatic adult the way it might be for blood pressure or cholesterol. The distinction matters because it shapes what primary care physicians do by default, and it has implications for how screenings are billed and prioritized in clinical settings. However, if a patient presents with concerns — or if a family member raises them on the patient’s behalf — the calculus changes. The USPSTF guidance advises clinicians to remain alert to early warning signs and to evaluate as appropriate when symptoms are present. In other words, the current evidence gap applies to the asymptomatic population, not to those who are already showing changes. Families should understand that an inconclusive national guideline is not a reason to delay evaluation when there are real, observable concerns.
How Medicare Covers Cognitive Assessments in Practice
One of the most practical and underused tools for annual cognitive monitoring is the Medicare Annual Wellness Visit. This visit, covered for Medicare beneficiaries, includes a cognitive assessment as part of a broader preventive health review. It creates a built-in touchpoint that many older adults and their families do not know exists or fail to use fully. The cognitive component of the Annual Wellness Visit is not a full neuropsychological evaluation. It typically involves a brief structured screening — the kind that takes five to fifteen minutes and identifies whether more in-depth testing is warranted.
Think of it as a first filter. If something flags during the visit, the physician can refer the patient for more comprehensive assessment by a neurologist, neuropsychologist, or geriatrician. For families navigating care for an aging parent, this is worth knowing because it reframes the question of access. The conversation does not have to start with a specialist referral. It can start at the primary care level, covered under an existing Medicare benefit, without additional out-of-pocket cost for most beneficiaries. If a family member has not used this benefit in the past year, that Annual Wellness Visit is a straightforward place to start.
High-Risk vs. Low-Risk Adults — How to Think About Your Own Timeline
The practical challenge with screening frequency is that “high risk” and “low risk” are not binary categories. Most older adults fall somewhere in between, with a mix of factors that may elevate risk in some areas and not others. A useful way to approach this is to consider risk in clusters: genetics, cardiovascular health, cognitive reserve, and lifestyle. Genetics includes family history of Alzheimer’s or other dementias, as well as genetic markers like APOE ε4 status, though genetic testing for dementia risk is not yet standard practice in most primary care settings. Cardiovascular health covers conditions like hypertension, atrial fibrillation, and type 2 diabetes, all of which are associated with increased dementia risk and are modifiable.
Cognitive reserve refers to factors like education level and mentally stimulating activity that may provide some protective buffer. Lifestyle includes sleep quality, physical activity, alcohol use, and social engagement. An adult with two or more cardiovascular risk factors and a parent with dementia should not wait two years between screenings, even if they feel fine. Conversely, someone in their late 60s who exercises regularly, has no significant medical history, and scored well on a screening two years ago may reasonably space assessments further apart. The tradeoff in less frequent screening is a longer window in which a change could go undetected — and for conditions that progress gradually, that window matters.
What Cognitive Screenings Actually Test — and Where They Fall Short
Standard cognitive screenings used in clinical settings assess a range of domains. Memory tasks might ask a person to recall a short word list after a delay. Executive function tasks might involve drawing a clock or alternating between letters and numbers. Language tasks assess naming, fluency, and comprehension. Visuospatial tasks examine the ability to perceive and reproduce spatial relationships. The limitation of these tools is that they are sensitive to education, cultural background, and the testing conditions themselves.
A person with a graduate degree may perform well on a brief screening even in early stages of decline, because their baseline cognitive reserve allows them to compensate. Conversely, someone with limited formal education might score lower on a standardized tool without any pathological change being present. This is a known and significant problem in cognitive screening equity, and it means a single score should never be interpreted in isolation. Repeated screening over time — using the same tools across visits — helps mitigate this problem by allowing clinicians to track change within the individual rather than comparing against a population average. A five-point decline on a standardized score over eighteen months is more informative than any single score taken without context. This is one reason why frequency matters: a baseline established early, and followed consistently, is more useful than a one-time assessment done when a family is already worried.
The Shift Toward Biomarkers and Personalized Assessment in 2025 and Beyond
The 2025 Alzheimer’s Association clinical practice guideline for specialty care reflects a meaningful shift in how cognitive evaluation is being approached. Under the DETeCD-ADRD framework — Diagnostic Evaluation, Testing, Counseling, and Disclosure for Alzheimer’s Disease and Related Dementias — there is growing emphasis on integrating blood-based biomarkers alongside traditional screening tools when indicated. These biomarkers include amyloid and tau proteins detectable through blood tests, as well as neuroimaging modalities such as MRI and PET scans.
This does not mean every older adult needs a blood biomarker panel at their annual wellness visit. It means that for those being evaluated in specialty settings — or those with a family history and early symptoms — the diagnostic picture is increasingly richer and more individualized than a brief pen-and-paper screen. The approach is designed to be personalized, accounting for genetics, comorbidities, and lifestyle. For families supporting a loved one through this process, the key implication is that early evaluation by a specialist can now offer more nuanced information than it could even five years ago.
Starting the Conversation — Why Timing and Framing Matter
One of the most consistent barriers to cognitive screening is the reluctance to initiate the conversation — among patients who fear the results, among family members who don’t want to alarm a parent, and occasionally among clinicians who feel the topic is sensitive to raise without a clear clinical trigger. The result is that screenings often happen later than they should, prompted by a crisis rather than a routine check.
The shift in framing that tends to help is treating cognitive screening the way most people treat annual bloodwork: as baseline data collection rather than a test you pass or fail. Starting that baseline early — at 65, or even at 60 for high-risk individuals — means that if and when changes occur, there is something to compare against. Waiting until concern is obvious means starting without a reference point, which makes the trajectory harder to interpret and the window for early intervention narrower.
Conclusion
For older adults without notable symptoms or risk factors, annual cognitive screenings starting at age 65 represent the most widely supported baseline. For those with elevated risk — cardiovascular disease, family history, or subjective cognitive complaints — every six to twelve months is more appropriate. The USPSTF has noted insufficient evidence for universal screening of asymptomatic adults, but this does not apply to individuals who are already showing signs of change. Medicare’s Annual Wellness Visit provides a covered, practical annual touchpoint that many families overlook.
The most important practical step is establishing a baseline early and monitoring consistently over time. As 2025 guidance from the Alzheimer’s Association underscores, cognitive evaluation is becoming more personalized and more biomarker-informed than in previous decades. The question is no longer just whether to screen, but how to match the depth and frequency of assessment to each person’s individual risk profile. Families who engage with this process proactively — rather than waiting until something goes clearly wrong — are in a meaningfully better position to act on what they learn.
Frequently Asked Questions
Can a primary care doctor perform a cognitive screening, or does it require a specialist?
A primary care physician can perform a brief cognitive screening using standardized tools and does so as part of the Medicare Annual Wellness Visit. Specialist referral to a neurologist, geriatrician, or neuropsychologist is typically recommended when screening suggests a concern or when a more comprehensive evaluation is needed.
Are cognitive screenings painful or invasive?
Standard cognitive screenings are entirely non-invasive. They involve verbal questions, simple drawing tasks, and recall exercises. Blood-based biomarker tests require a blood draw but are not part of routine primary care screening at this time.
What happens if a screening result is concerning?
A concerning result triggers further evaluation rather than a diagnosis. The next steps typically include more comprehensive neuropsychological testing, imaging, and sometimes specialist consultation. A single screening score is not sufficient for a dementia diagnosis.
Is there a cognitive screening my family member can do at home?
Some validated tools can be completed with family assistance, but home-based self-assessments are not a substitute for clinician-administered screening. They may be useful for tracking subjective changes between appointments, but the results should be shared with a physician rather than interpreted independently.
What if my parent refuses to be screened?
Refusal is common and often rooted in fear of the result. Framing the conversation around baseline data collection rather than diagnosis — and emphasizing that early detection expands options rather than closes them — can help. In some cases, bringing it up as a routine part of an annual physical, rather than a separate “memory test,” reduces resistance.
Does Medicare cover cognitive screenings beyond the Annual Wellness Visit?
The Annual Wellness Visit includes a cognitive assessment at no additional cost to beneficiaries. Additional testing beyond that visit may be covered if there is a documented clinical reason, but coverage depends on the specific tests ordered and the beneficiary’s plan.
