Handwriting speed among possible signs of cognitive decline in older people

> The study included 58 older adults, aged between 62 and 92, living in care homes. 38 participants had previously been diagnosed with a form of cognitive impairment. Participants performed two types of tasks using an inking pen on a digitizing tablet. During pen control tasks, participants were prompted to draw 10 horizontal lines within 20 seconds and make at least 10 dots on the paper during the same time frame. The handwriting speed task included noting down two sentences of varying complexity that were either shown on a card or dictated, respectively.

>Results showed that neither of the pen control tasks could distinguish cognitive status between groups. As ‘simple’ tasks, they mainly rely on basic motor control and may not be enough to reveal subtle differences that more cognitively taxing tasks can show. Copying tasks, which are more mentally demanding than pen control but less demanding than dictation, also didn’t show group differences but demonstrated a trend towards significance.

>The results of the dictation tasks, however, showed clear differences between the two participant groups. This could be due to the higher cognitive demand such tasks place on working memory and executive functions. “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,” said Matias. “Even within dictation tasks, differences can emerge. A longer, less predictable, or linguistically demanding sentence places greater strain on cognitive resources.”

>In the group with cognitive impairment, two predictors – start time and number of strokes – emerged as significant for the shorter sentence of the dictation task. For the more complex sentence three predictors – vertical size, start time, and duration – were significant. This could be due to not all handwriting features reflecting cognition in the same way.

>“Timing and stroke organization are closely linked to how the brain plans and executes actions, which depends on working memory and executive control. As these cognitive systems decline, writing becomes slower, more fragmented, and less coordinated,” explained Matias. “In contrast, other features can remain relatively preserved, especially in the early stages of cognitive decline, making them less sensitive indicators.”

How about typing speed. I haven’t actually written a full sentence on paper in over a decade. My hand writing is basically limited to signing documents, receipts, etc.

perhaps, the observation should be simply the declining rate at which ordinary tasks in general are performed by healthy individuals is an indicator of cognitive decline.

yeah when they start writing all slow and sloppy its bad, who knew?

GenZ out here wondering what handwriting is

Sheesh, don’t look at me. I’m left handed and my handwriting has always been slow and mostly legible and faster and illegible. In college all my papers were printed to avoid the whole issue.

I don’t think it is useful anymore. I VERY rarely write anything now. Not even signatures. It’s all electronic devices.
