The 5 word test is a simple cognitive screening tool used to detect early signs of memory impairment, particularly associated with Alzheimer’s disease. A person is asked to read and memorise five words, then recall them after a short delay. It was developed as a more sensitive alternative to the standard three-word recall used in the Mini-Mental State Examination. A score of less than 10 out of 20 points suggests a memory problem that warrants further investigation. The test takes only a few minutes and can be administered by a GP. It is only a screening tool, not a full diagnosis, as many things including stress, hearing problems, or poor sleep can affect performance.
