有人估计美国成年人10—15％患有显著的耳聋病。但是到目前为止,对其发病原因知道得还很不够。据1968年的统计,将其病因归纳为:20％为传染病所致;7％由于创伤,35％列为原因不明;另外35％则“诊断含糊”(包括老年性、遗传性和噪声性等耳聋)。很久以来,人们都认为听力减退是衰老不可避免的结果。如果老年性聋只是由于衰老所致,那么,生活在同样环境中的人,为什么有人在60岁时就出现耳聋而有人80岁时听力仍旧很好? 遗传影响对成年听力减退肯定起着重要作用,但至今尚未受到重视。本文目的就是要强调成年人遗传性听力减退所占的地位,并简要地说
It is estimated that 10-15% of U.S. adults suffer from significant deafness. But so far, I do not know enough about the cause of the disease. According to the 1968 statistics, the etiology was summarized as follows: 20% were caused by infectious diseases; 7% were classified as unexplained by 35% because of trauma; and 35% were “vaguely diagnosed” (including senility, heredity and noise Other deafness). For a long time, people all think hearing loss is the inevitable result of aging. If senile deafness is due only to aging, then why do people who live in the same environment have deafness at the age of 60 while others still have good hearing at age 80? The genetic effect certainly plays an important role in adult hearing loss , But so far it has not been taken seriously. The purpose of this article is to emphasize the status of adult hereditary hearing loss, and briefly
