Alzheimer's early warning may be hidden in your handwriting! Here are three signs to watch for.

A new study has been added to research aimed at early diagnosis of Alzheimer’s and dementia. Scientists said that changes in handwriting could be linked to brain functions and could provide important clues in the early stages of cognitive decline.

Handwriting Reflects Cognitive Processes

Handwriting is not just about hand and finger movements. It simultaneously requires many cognitive processes such as motor control, interpreting information, memory, and regulating movements on the page. Therefore, changes can occur in the writing process as conditions like Alzheimer’s or dementia develop.

In the study announced via EurekAlert!, the speed and complexity of handwriting of a group of older adults were examined. The study included 38 nursing home residents who had previously been diagnosed with a cognitive disorder and 20 people with no diagnosis of cognitive disorder.

Three Significant Differences Were Observed Between the Two Groups

Participants in the study were asked to complete different writing tasks using a digital pen and tablet. They both copied a sentence given to them and wrote a more complex sentence that was read aloud.

The findings obtained indicate significant differences between individuals with cognitive impairment and other participants.

The three prominent changes highlighted in the study were listed as follows:

Slower writing: Individuals with cognitive impairment required more time to complete writing tasks.

Late start to writing:These individuals waited longer before starting the task assigned to them.

Larger Letters:Participants with cognitive impairment were observed to write their letters larger than those in the other group.

Cognitive decline in the brain slows writing.

Dr. Ana Rita Matias from Evora University who oversaw the research stated that the timing and pattern of writing are closely linked to the brain's planning and execution capabilities.

Matias stated that as cognitive systems decline, writing may become slower, fragmented, and uncoordinated. According to the researcher, particularly pauses between pen movements could indicate that the brain is having greater difficulty planning the next movement.

Another study published in the National Library of Medicine also evaluated handwriting as a potential tool for the early diagnosis of Alzheimer's and dementia.

How Can Handwriting Be Checked at Home?

One of the methods that experts highlight is writing down sentences read aloud. Unlike copying a visual text, writing by dictation requires the combined use of memory, attention, and motor coordination.

Therefore, it is noted that the following changes can be observed while writing:

- Long pauses between pen strokes compared to normal

- Noticeable slowing of writing speed

- Letters and words becoming more fragmented and irregular

However, it should not be forgotten that such home-based tests cannot diagnose Alzheimer or dementia. Changes in handwriting can also arise due to aging, vision problems, joint disorders, and various neurological conditions.

If a clear and lasting change in writing skill is observed, it is recommended to consult a health professional for early assessment.
