SAGE Test: What It Is and How It's Used

Why the SAGE Test Matters

SAGE was developed by Dr. Douglas Scharre and his team at The Ohio State University Wexner Medical Center to give people a low-barrier way to check in on cognition early. Because it needs only pen and paper and can be completed at home, in a waiting room, or in a physician's office, it removes some of the practical hurdles that keep people from raising memory concerns in the first place (Ohio State University Wexner Medical Center).

That accessibility appears to make a real difference in practice. In a 2024 study, primary care providers who used SAGE documented new cognitive conditions in 9% of patients, compared with just 1.5% among patients who did not take the test — roughly a sixfold increase in early detection (Scharre et al., Frontiers in Medicine, 2024). If you are new to this topic, our overview of cognitive testing explains how brief screens like this fit into the larger picture of brain health.

What the SAGE Test Measures

Rather than testing a single skill, SAGE samples several areas of thinking that can change when cognition is affected. Across its questions, it assesses seven domains: orientation, language, memory, executive function, abstraction, calculations, and visuospatial abilities, for a maximum score of 22 points (Scharre et al., Alzheimer's Research & Therapy, 2017).

Sampling multiple domains gives a clinician a broader snapshot than a very short screen can. For a wider view of how SAGE compares with other tools, see our guide to the types of cognitive tests. Because SAGE covers more ground than a three-minute check, it is often positioned as a middle option between the briefest screens and a full evaluation.

How the SAGE Test Is Taken and Scored

SAGE is genuinely self-administered: you read the instructions and answer the questions yourself, with no examiner reading items aloud. It requires no special equipment beyond pen and paper and comes in four interchangeable versions, which lets a clinician repeat it over time without reusing the same form (Ohio State University Wexner Medical Center).

Scoring, however, is not a do-it-yourself step. The developers deliberately do not publish a self-scoring answer key, because many questions have more than one acceptable answer — SAGE is meant to be scored by your physician. On average the test takes about 13 minutes to complete and under a minute for a trained clinician to score (Scharre et al., 2017). This division of labor is intentional: it keeps the test easy to take while keeping interpretation in qualified hands. Because it is longer than a quick screen, it can take more time than tools like the Mini-Cog, which is designed for very brief visits.

Understanding SAGE Scores

SAGE produces a single total out of 22 points, and a clinician reads that number alongside your history rather than as a simple pass or fail. In the original validation study, SAGE identified about 79% of people with cognitive impairment (sensitivity) while correctly classifying about 95% of those without it (specificity), and its scores correlated strongly with detailed neuropsychological testing (Scharre et al., 2010).

In practice, several things shape how a clinician interprets a result:

• Your history — recent changes matter more than a single number
• Daily functioning — how thinking affects everyday activities
• Other findings — mood, sleep, medications, and physical health
• Follow-up over time — one screen is a snapshot, not a trend

Because the four versions are interchangeable, SAGE can also be repeated to watch for change, which is often more informative than any one score in isolation.

Can the SAGE Test Diagnose Dementia?

No. SAGE does not diagnose any specific condition, and its results will not tell you whether you have Alzheimer's disease, a small stroke, or any other disorder (Ohio State University Wexner Medical Center). As the Alzheimer's Association explains, there is no single test that determines whether someone is living with Alzheimer's or another dementia — clinicians combine cognitive assessments with medical history, physical and neurological exams, and sometimes brain imaging or lab work (Alzheimer's Association).

When a SAGE result is lower than expected, a provider may look for treatable contributors and recommend further evaluation. SAGE is often discussed alongside clinician-administered screens such as the MoCA test and the MMSE, which are given and scored by a professional in the office.

When You Might Use SAGE

You might complete a SAGE if you or a family member has noticed memory or thinking changes, or if a clinician suggests it as a baseline to revisit later. Because you can fill it out on your own and bring it in, it can be a comfortable way to start a conversation you have been putting off. A concerning result is a prompt for more discussion, not a conclusion.

What Happens Next

After you complete SAGE, your clinician scores it and explains the result in the context of your overall health. Sometimes that means reassurance and a plan to recheck later; other times it means a referral for more detailed testing. Either way, the aim is clarity and an informed next step rather than alarm.
