Pen holding may indicate a risk ofAlzheimer's disease — May be the largest murderer in the UK I know from the survey.
Alzheimer's disease, the most common form of dementia, gradually loses one's memory and ability to perform daily tasks.
It can be difficult to find because it progresses over the years.
However, human behavior has some early clues that can signal an upcoming potentialdiagnosis, from bad parking to changing humor. I have.
The newly identified red flag can occur if Grandma's handwriting on the birthday card is a little wobbling.
Pen and paper tests are often used by GPs to diagnose Algerhemier, requiring a person to draw a star or clock face from memory.
The lower your ability, the more likely you are to have dementia.
Researchers at the University of Tsukuba have found other signs that may appear much earlier in pen and paper tests.
They recruited 144 people with different levels of cognitive ability, including those with dementia and those who are perfectly healthy.
Each participant measures 22 drawing features 5 I took a different drawing test.
These include pressure, pen posture, velocity, and how often a person pauses.
Next, researchers can compare these features and use computer-based programs to identify people using drawing characteristics with or without normal cognition. I checked if it was.
Some patients hadmild cognitive impairment(MCI). This is when someone has a memory loss that is a little worse than aging, but not as severe as dementia.
They can still do their daily activities.
Researchers were able to find people using MCI or Azlheimer based on their drawing style.
Due to the large variation in pen pressure, some lines were smooth and strong, while others were weak and wobbled.
Pauses are longer and slower.
The accuracy of the five tests for detecting people with Alzheimer's disease was 75.2% overall.
Professor Tetsuaki Arai, a senior author of the study, said:
"I wondered what would happen if I analyzed these characteristics when people were performing various drawing tasks.
" Three groups of all five tests The accuracy was 75.2%, almost 10% better than the test itself. ”
Alzheimer's disease is 1 in 14 people over 65 years old, over 80 years old It is estimated to affect 1 in 6 people.
This is not a normal part. It causes aging and forgetssimple things like how to tie shoelaces and tell time.
But in the worst case, patients forget their decades of partners and their children.
This disease is incurable, but there are medicines to relieve the symptoms.
Early diagnosis helps you plan for the future while you can make decisions.
