Pen-and-Paper Test to Spot Early Alzheimer's

The Self-Administered Gerocognitive Examination (SAGE test), which takes less than 15 minutes to complete, is a reliable tool for evaluating cognitive abilities. Findings by researchers at The Ohio State University Wexner Medical Center confirm the feasibility and efficiency of the tool for community screening of large numbers of people. The study is published in the January 2014 issue of The Journal of Neuropsychiatry and Clinical Neurosciences.

The simple pen-and-paper test checks for orientation (month + date + year); language (verbal fluency + picture naming); reasoning/computation (abstraction + calculation); visuospatial (three-dimensional construction + clock drawing); executive (problem solving) and memory abilities. Missing six or more points on the 22-point SAGE test usually warrants additional follow-up.  

According to a release from the center, memory disorders researchers visited 45 community events where they asked people to test to screen for early cognitive loss or dementia. Dr. Douglas Scharre, who developed the test with his team at Ohio State, reported that of the 1047 people who took the test, 28% were identified with cognitive impairment. Dr. Scharre is director of the Division of Cognitive Neurology and heads the Memory Disorders Research Center at Ohio State's Wexner Medical Center

The SAGE test can also be taken at home. People can then share the results with their physicians. Often physicians may not recognize subtle cognitive deficits during routine office visits.

The release quotes Dr. Scharre as saying, "What we found was that this SAGE self-administered test correlated very well with detailed cognitive testing. If we catch this cognitive change really early, then we can start potential treatments much earlier than without having this test." Dr. Scharre added that treatments for Alzheimer's and dementia are more effective when started in the earliest stage of the disease. Unfortunately, patients with Alzheimer's disease often wait three to four years after their symptoms first appear to seek treatment.

While the test does not diagnose problems like Alzheimer's, it does allow doctors to get a baseline of cognitive function in their patients so they can follow them for these problems over time. "We can give them the test periodically and, the moment we notice any changes in their cognitive abilities, we can intervene much more rapidly," Dr. Scharre said.

The SAGE test could also provide health care providers and caregivers an earlier indication of life-changing events that could lie ahead. Earlier research by Dr. Scharre found that four out of five people with mild thinking and memory issues will be detected by this test, and 95% of people without issues will have normal SAGE scores.
