American scientists have warned a few days ago: “Elderly people with poor hearing, with age, the possibility of suffering from Alzheimer’s disease will greatly increase.”

     This study was initiated by Frank Lin, a surgeon at Johns Hopkins University in the United States. After a 600-year survey of 36 men and women between the ages of 90 and 12, it was found that even after excluding age and other As a result of factors, people with mild hearing loss are twice as likely to suffer from dementia in the future than people with normal hearing; for those with moderate hearing loss, this number will increase to three times ; For people with severe hearing loss, it is up to five times.

     At the beginning of the investigation, all subjects underwent a hearing test, and none of them had dementia.During the study, about 9% of the subjects were suffering from various degrees of dementia.The researchers published an article in the “Archives of Neurology” that: the worse the hearing, the more severe Alzheimer’s disease is. “Does this mean that if your hearing is impaired, you will definitely get dementia? Of course not. But does it increase the chance of developing dementia? The answer is yes.”

     The reason for this phenomenon has not yet been identified, but there are three possibilities: XNUMX. Hearing loss and Alzheimer’s are caused by the same cause; XNUMX. The elderly with poor hearing are more likely to cope with the problem of mental decline. Difficulty; Third, the elderly with hearing loss will be isolated, leading to the occurrence of Alzheimer’s disease.

     Frank Lin is more inclined to the latter two possibilities, and believes that this research will have a huge impact on public health and medical expenditures.According to data from the National Institutes of Health, approximately 17% of American adults suffer from varying degrees of hearing loss.Frank Lin said that another study is underway to prove whether treating hearing loss can delay the onset of Alzheimer’s disease.
