You can test your memory at home using validated screening tools that take 10 to 15 minutes, or through informal exercises that challenge different types of memory. These range from pen-and-paper tests developed at research universities to digital apps and simple self-checks you can do right now. None replace a full clinical evaluation, but they give you a meaningful starting point for understanding how well your memory is functioning.
The SAGE Test: A Validated At-Home Option
The most reliable way to screen your memory at home is the Self-Administered Gerocognitive Examination, known as the SAGE test, developed at Ohio State University. It requires nothing more than a pen and paper, takes about 10 to 15 minutes, and covers several cognitive areas including memory, problem-solving, and language. A digital version is also available online through BrainTest.com.
The test comes in four interchangeable forms, which exist so you can retake it over time without the advantage of remembering previous questions. When taking it, you should use ink (not pencil), work without help from anyone else, and keep calendars and clocks out of sight. One important detail: there’s no self-scoring key because many questions have multiple correct answers. You’ll need to bring your completed test to a doctor for scoring and interpretation. That’s a feature, not a limitation. It means the results carry clinical weight and can become part of your medical record as a baseline for comparison over time.
Quick Screening You Can Try Now
The Clock Drawing Test is one of the simplest and most widely used cognitive screens. You draw a clock face from memory, place all twelve numbers correctly, and set the hands to a specific time (usually “ten past eleven”). It sounds easy, but it requires spatial reasoning, number sequencing, and the ability to translate an abstract instruction into a visual representation. Clinicians score it on a scale that evaluates whether numbers are in the right positions, whether the clock face is circular, and whether the hands point to the correct time. Errors like clustering numbers on one side of the clock or drawing hands to the wrong position can signal cognitive changes.
Another informal test: try recalling a short list of unrelated words. Read five words aloud, do something else for five minutes, then try to recall all five. Most people with healthy memory can recall at least three out of five after a short delay. This mirrors the “registration and recall” portion of clinical memory tests, where you’re given a short word list and asked to repeat it after an interruption.
How Professionals Test Memory
If you visit a doctor with memory concerns, they’ll likely use one of two standardized assessments. The Montreal Cognitive Assessment (MoCA) is a 30-point test that evaluates memory alongside attention, language, reasoning, and spatial awareness. Scores of 25 to 30 are considered normal, 20 to 24 suggest mild impairment, and 19 or below indicates moderate impairment.
The Mini-Mental State Exam (MMSE) is another common option, also scored out of 30. It tests eight specific areas: orientation to time, orientation to place, registration, attention and calculation, recall, language, repetition, and the ability to follow complex commands. Higher scores mean better function. Both tests take under 15 minutes and are administered in a doctor’s office, not a lab or hospital.
These clinical tools measure more than raw memory. They test whether you can hold information in mind while doing something else, whether you know where and when you are, and whether you can follow multi-step instructions. That broader picture is what makes them more useful than any single memory exercise you could do alone.
Testing Working Memory Specifically
There’s a difference between long-term recall (remembering your cousin’s name) and working memory (holding a phone number in your head while you walk across the room to write it down). If you’re curious about your working memory specifically, the n-back task is the gold standard in cognitive research.
In an n-back task, you see a sequence of items, one at a time, and have to identify when the current item matches one that appeared a set number of steps earlier. In a 1-back version, you’re checking if the current item matches the one right before it. In a 2-back, you’re comparing it to the item two steps ago. As the number increases, so does the mental load, because you have to continuously update what you’re holding in mind while discarding older information. Free n-back apps and browser-based versions are widely available. Unlike static tasks such as remembering a string of digits, the n-back requires you to actively manipulate and refresh information, which is a more demanding and revealing test of working memory capacity.
Digital Tools With Research Backing
Many memory-testing apps exist, but few have been rigorously validated. The NIH Toolbox stands out as an exception. Developed by the National Institutes of Health, it offers over 50 neurobehavioral assessments through an iPad app, covering cognition, motor function, sensation, and emotion. It has been cited in more than 300 peer-reviewed publications and was updated to its current version in 2022. It’s primarily used in research and clinical settings, but it represents the benchmark that consumer apps are measured against.
If you’re using a consumer app like Lumosity, Peak, or CogniFit, keep your expectations calibrated. These can be fun and may track your performance over time, but their scores don’t translate directly to clinical diagnoses. They’re best used as a way to notice trends in your own performance rather than as a substitute for validated screening tools.
Normal Forgetfulness vs. Warning Signs
Before you test your memory, it helps to understand what “normal” looks like. The National Institute on Aging draws a clear line between age-related forgetfulness and signs of dementia. Forgetting which day it is and remembering later is normal. Losing track of the date or time of year consistently is not. Missing a monthly payment once happens to everyone. Struggling to manage monthly bills is a different pattern. Sometimes forgetting which word to use is ordinary. Having persistent trouble holding a conversation is a red flag.
The CDC identifies several specific warning signs worth taking seriously: getting lost in a familiar neighborhood, using unusual words for everyday objects, forgetting the name of a close family member or friend, forgetting old memories that were previously well-established, and being unable to complete routine tasks independently. The key distinction in almost every case is frequency and severity. Occasional lapses are part of being human. A pattern of worsening difficulty with things that used to come easily is what warrants professional evaluation.
Getting the Most Accurate Results
Your memory performance on any given day is influenced by factors that have nothing to do with your brain’s long-term health. Stress, dehydration, medication side effects, and illness can all temporarily drag down your scores. If you’re testing yourself at home, do it when you’re rested, hydrated, and in a quiet environment without distractions.
Interestingly, one night of poor sleep may not affect your scores as much as you’d expect. A study of healthy young adults found that one night of total sleep deprivation did not significantly change performance on the MoCA or trail-making tests. That said, chronic sleep deprivation over weeks or months is a different story and can meaningfully impair both memory consolidation and retrieval. The takeaway: don’t panic if you test yourself after one rough night, but don’t use a single good result to dismiss concerns if you’ve been sleeping poorly for months.
If you plan to track your memory over time, take your baseline test when you feel well, note the date, and retest at regular intervals, perhaps every six to twelve months. Use one of the alternate SAGE forms each time to avoid the practice effect. Bring all your results to your next medical appointment so your doctor can look at the trajectory rather than a single snapshot.
