Cognitive Self-Test (SAGE)
Free 15-minute screening. Done at home with paper and pen.
What SAGE is
The Self-Administered Gerocognitive Examination — a free, validated test from Ohio State University. Used by tens of thousands of doctors. Catches early signs of cognitive impairment that lead to dementia. NOT a diagnosis — but flags whether you should see a doctor.
When to take it
- Forgetting things more than usual.
- Family is concerned.
- Repeating yourself.
- Trouble with new technology you used to handle fine.
- Getting lost in familiar places.
- As a baseline, even if you\'re fine — having a "normal" score on file makes any future change easier to detect.
How to take it
- Go to sagetest.osu.edu and download the free PDF (4 different versions).
- Print it. You\'ll need a pen and a quiet 10-15 minutes.
- NO time pressure. Take as long as you need.
- Don\'t look up answers, don\'t use a calculator.
- When done, give the paper to your doctor at your next visit. Or you can score it yourself using the answer key — but the doctor\'s read is what matters.
Score 17+ out of 22 = normal. 15-16 = mild concern. Below 15 = should be evaluated. NOT a final answer; just a starting conversation.
Other free options
- Mini-Cog — your doctor can do it in 3 minutes. Just ask at your next visit.
- BrainTest (paid app, $30) — at-home tablet test. Mixed reviews.
- Annual wellness visit — Medicare covers a free yearly cognitive screening as part of your annual wellness check. Most patients don\'t know to ask. Ask: "Can we do a cognitive screening today?"
If results concern you
Many things mimic dementia and are FIXABLE: medications, depression, B12 deficiency, thyroid, sleep apnea, even hearing loss. See your primary doctor first. Get bloodwork. Then if needed, ask for a neurology referral.
Early intervention matters. New treatments (lecanemab, donanemab) work better the earlier they start. Don\'t put off a doctor visit out of fear.
Best dementia prevention isn't apps
Daily walks, social engagement, learning a language, treating high BP and diabetes, sleeping well, treating hearing loss. The data on these is much stronger than on brain-training apps.
