How Accurate is the 12-Question Alzheimer’s Test? A Detailed Breakdown
Dementia Care
By Nurse Next Door April 30, 2025
Alzheimer’s disease is a progressive brain disorder involving impairment of memory, thinking, and behavior. Over 55 million people suffer from dementia. Among these affected individuals, 60 to 70% of cases may involve Alzheimer’s disease as the leading cause.
Early diagnosis of Alzheimer’s disease not only allows the appropriate treatment to begin on time but also prevents the disease from progressing. Among various diagnostic techniques, the SAGE test, also known as the Alzheimer’s test 12 questions, is a popular option in the US. But how accurate is it?
This article explores various aspects of the Alzheimer’s test 12 questions and this test compares to other diagnostic tools.

Understanding the 12-Question Alzheimer’s Test
The Alzheimer’s test 12 questions are essentially the Self-Administered Gerocognitive Exam (SAGE). The researcher, Douglas Scharre, with his team at the Ohio State University (OSU) Wexner Medical Center, devised this test.
The SAGE test helps detect the early signs of Alzheimer’s disease and dementia by assessing mental functions like thought, memory, and cognition. It is a little more complex than other tests like the mini-mental state examination (MMSE). It assists in detecting even mild memory or behavior dysfunction.
Format of the SAGE Test
The test initially asks about your background and health. It then proceeds with tasks like naming objects, drawing a clock, and simple problem-solving questions. Overall, it would take you around 10–15 minutes to complete the Alzheimer’s test 12 questions online.
Who Should Take the SAGE Test?
A person can attempt to answer the Alzheimer’s test 12 questions online if they feel any changes in their thinking skills or memory. Sometimes, your friends or family might notice changes in your behavior and share their concerns. The test is also used in clinical settings.
The target audience for this test is adults aged 50 and above who might be having some memory issues or other cognitive changes.
All Stages of Alzheimer’s Disease
Accuracy of the Alzheimer’s Test 12 Questions
When introduced in 2010, the test’s developer, Douglas Scharre, conducted an initial study with other researchers to evaluate the test’s effectiveness. The study demonstrated that the SAGE test demonstrated 79% sensitivity and 95% specificity in identifying patients with cognitive impairment.
According to another study conducted in 2017, the digital version of the SAGE test has 90% specificity and 71% sensitivity in detecting cognitive impairment.
The Sage Test or the Alzheimer’s test 12 questions may help detect even mild cognitive impairment. However, it can not specify if a person has dementia, Alzheimer’s disease, or any other neurological condition. Besides that, other factors like age and education level can also affect the test scores.
When compared with the Mini-Mental State Exam (MMSE), a standard exam for testing cognitive ability, the SAGE test has higher sensitivity and specificity rates.
While answering the Alzheimer’s test 12 questions online is useful, one should consider it as an initial step. Experts suggest proceeding to other clinical evaluations, like neuropsychological evaluations or imaging, afterward.
The SAGE test is accessible, easy to administer, and ideal for early self-screening at home. According to its developer, Dr. Douglas Scharre, the SAGE Test can help people realize when to seek medical help before their symptoms worsen. In short, attempting the Alzheimer’s test 12 questions online is a great initial step for screening for dementia and Alzheimer’s disease, but not a substitute for a professional evaluation.
Comparison with Other Tests
The traditional cognitive screening tools include the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA).
- MMSE is widely used in clinical practice to screen for dementia. It includes structured cognitive assessments and takes about 10 minutes. This test has a sensitivity of about 64%, so it may miss early cognitive issues.
- MoCA (Montreal Cognitive Assessment) is a more detailed test. With a sensitivity of up to 90%, it is better at spotting mild cognitive impairment.
