Certain handwriting features such as writing efficiency and coordination may shed light on the cognitive health of older adults, according to a new study from Portugal published in the Frontiers in Human Neuroscience journal.
What the Study Found
Researchers evaluated 58 adults ages 62 to 92 living in care homes — 38 with a diagnosed form of cognitive impairment and 20 without. Participants performed two types of tasks: simple pen-control tasks (drawing lines and dots) and dictation tasks (writing sentences read aloud).
There were no meaningful differences between groups on the simple tasks, as those "mainly rely on basic motor control." However, when it came to dictation — requiring language processing, working memory, and executive control — significant differences emerged. In the cognitively impaired group, movements became "more constrained, fragmented and less smoothly organized."
"The strongest message is that handwriting becomes informative when the task is cognitively demanding. Simple dots/lines are not enough; dictation better exposes cognitive-motor vulnerability."

Dr. Richardson, a family medicine physician, was quoted by HuffPost as an independent medical expert to provide clinical context on the findings:
"The study suggests that handwriting exercises, specifically writing sentences read aloud, may reveal signs of cognitive decline, possibly because the task is more mentally demanding than simply copying text. While that's an interesting finding, it's important to recognize that the study only included 58 institutionalized older adults, so it may not reflect what we'd see across the broader population and in our communities."
Dr. Richardson also offered a practical takeaway for families:
"Their family physician knows their health history and can help determine whether further evaluation is needed."
Dr. Richardson noted that if you notice a loved one struggling to write down instructions or becoming easily confused, it is worth making an appointment with a healthcare provider to review their cognitive health.
What This Means For You
The researchers caution that handwriting should be explored as a "low-cost screening and monitoring marker, not yet as a standalone diagnostic tool." Larger studies with more diverse populations are still needed.
Beyond handwriting, broader lifestyle factors remain important for cognitive health including physical activity, quality sleep, learning new skills, and staying socially connected.
