Researchers at Portugal's University of Evora have identified a link beween sluggish handwriting and a heightened chance of dementia among people in their 80s. Using a digital pen and pad, the team measured how quickly participants could transcribe spoken sentences, discovering that those with mild cognitive impairment wrote noticeably slower.

58 Portuguese seniors in their 80s wrote slower during dictation tasks

In a sample of 58 adults aged around 80, the study recorded a clear speed gap between participants with mild cognitive impairment (MCI) and those without. According to the report , the MCI group took longer to complete dictatioon exercises, suggesting that writing speed reflects underlying working‑memory and executive‑function deficits.

Digital pen captures fragmented stroke patterns in cognitively impaired participants

The researchers employed a digital pen and tablet to monitor not only speed but also the continuity of each stroke. They observed that individuals with MCI produced more broken, less fluid strokes, a pattern that "could be a window into the brain," said Dr. Ana Rita Matias, assistant professor at the University of Evora.

Handwriting test proposed as low‑cost alternative to MoCA

Current early‑dementia screening relies on the Montreal Cognitive Assessment (MoCA), a standardized but resource‑intensive tool. The study’s authors argue that a simple handwriting task could serve as a cheaper, scalable monitor for cognitive decline, especially in community settings where full neuropsychological testing is impractical .

Open question: Will clinicians adopt pen‑based screening over established tests?

While the findings are promising , the article notes that larger, longitudinal trials are needed to confirm whether handwriting speed can reliably predict dementia progression. It also remains unclear how the method performs across diverse languages and cultural writing habits .

Expert caution: Handwriting is a clue, not a diagnosis

Dr. Walter van der Lans, associate professor at UCLA, emphasized that "simple, practical cognitive tests like the one used in the study could help identify people at risk of dementia," but warned that such tools should complement, not replace, comprehensive clinical evaluation.
