Everyday task may help detect early dementia signs before diagnosis, study finds

A simple writing test could detect cognitive impairment in older individuals before more serious symptoms occur, scientists have discovered.

Writing is a complex, brain-heavy workout that requires the mind to process information, organize thoughts and send precise signals to the fingers all at once, according to experts.

Because writing draws on so many complex mental functions, researchers believe that small changes in how people write could provide early warning signs for cognitive impairment.
