With more people being diagnosed with Alzheimer’s disease, doctors say it’s critical to identify problems with memory and thinking as soon as possible. Now, a simple test could help, called the Self-Administered Gerocognitive Examination, or S.A.G.E. test. The four-page test, developed at Ohio State University, was given to people 50 and older, measuring language, reasoning, problem solving and memory. The S.A.G.E. test can be taken at home, the senior center or the doctor’s office in less than 15 minutes.
