Study Finds Basic Handwriting Tasks Show Little Difference in Older Adults With or Without Cognitive Impairment

Researchers in Portugal found that dictation writing tasks revealed slower, more fragmented and less coordinated patterns among older adults with cognitive impairment compared with those without such diagnoses. The study included 58 adults between the ages of 62 and 92 living in care homes. Thirty-eight of the participants had already been diagnosed with cognitive impairment.

Participants completed writing exercises on a specialized digital tablet that recorded precise hand movements while they used an ink pen. The exercises included basic pen control, copying sentences from a flashcard, and writing sentences spoken aloud. Simple tasks such as drawing lines or copying text showed no major differences between the two groups.

In contrast, dictation tasks produced clear distinctions. Adults with cognitive impairment took longer to begin writing, paused more often and had greater difficulty organizing strokes when writing from dictation. "Dictation tasks are more sensitive because they require the brain to do multiple things at once: listen, process language, convert sounds into written form and coordinate movement," Dr.

Ana Rita Matias, the study's senior author from the University of Évora, stated in a press release. Matias said the long-term goal is to develop a tool that is easy to administer, time-efficient and affordable, allowing integration into everyday healthcare contexts without requiring specialized or expensive equipment. The study was published in Frontiers in Human Neuroscience.

It did not account for participants' use of medications. Currently, diagnosing cognitive decline often involves expensive brain scans or lengthy psychological testing. The researchers noted that larger and more diverse groups need to be tested to confirm the findings.
