When someone has two disorders at the same time, it may increase the risk of isolation and depression.
Hearing or vision impairment is not just a sign of aging.
.
.
April 7, 2021, the American Academy of Neurology published in Neurology "The study said: Loss of hearing or vision function may put patients at greater risk of dementia and cognitive decline years later.
But the study did not find such a connection just by losing one of the senses.
This study was supported by the Korea Centers for Disease Control and Prevention.

0000000000011845" Depending on the degree of hearing or vision loss, loss of sensory function may be Daily life has an impact and it is painful.
" said the research author, Dr.
JinHyeong Jhoo, School of Medicine, Gangwon National University, Chuncheon, Korea.
"But the results of this study show that after the loss of these two functions, other effects are more worthy of attention.
"The study investigated 6,520 elderly people between the ages of 58 and 101.
Researchers used questionnaires to ask about the use of glasses or hearing aids to determine the degree of vision and hearing impairment, and rated hearing as "normal", "hearing loss, but able to communicate without hearing aids", "difficulty communicating with hearing aids" or " There is no hearing at all.
" In terms of eyesight, the eyesight is rated as "normal" or "decreased, but you can read newspapers or TV without glasses.
"
When evaluated, it was found that 932 people had normal vision and hearing, 2957 had visual or hearing impairment, and 2631 had two dysfunctions.
So what is the relationship between dementia and these two functional losses? Studies believe that suffering from two dysfunctions can cause the incidence of dementia to triple.
From the data point of view, 201 of 2631 people (with two dysfunctions) suffer from dementia, accounting for 8%.
In contrast, people with one type of disorder (2957 people) accounted for 2.
4%, and people without sensory impairment (932 people) accounted for 2.
3%.
For 6 years, the researchers used a test every two years on subjects to assess people's thinking and memory, such as word recall and recognition.
They also analyzed the relationship between one of them and dementia, and the relationship between two disorders and dementia at the same time.
In the end, a total of 245 people developed dementia.
Among the 1964 people with two types of disorders, 146 were suffering from dementia, of 2396 people with one type of disorder, 69 were suffering from dementia, and among the 737 barrier-free people, 14 were suffering from dementia.
Of the 142 people who are unsure whether they have functional impairments, 16 have already suffered from dementia.
After adjusting for factors such as gender, education, and income, the researchers found that people with two disorders are twice as likely to suffer from dementia as the functional group.
People with only one disorder are not more likely to suffer from dementia than normal people.
Judging from the scores of the thinking ability test, people with two kinds of obstacles have a faster decline.
The researchers said that as to why people with two disorders have a greater risk of dementia than people with one disorder, we are still studying.
"Usually, elderly people with only one disorder can still stay social, and they may not feel isolated or depressed.
When someone has both disorders at the same time, they may increase the risk of isolation and depression.
Previous studies have found that, This may affect cognitive ability and thinking ability.
" The researcher said.
Of course, the study has limitations.
The questionnaire for this study did not measure hearing and vision more accurately, which may affect the results of the study.
