Hearing Problems May Speed Mental Decline
 
Hearing loss may increase the risk of problems with memory and thinking in older adults, a study suggests. The study included 1,984 people in their 70s and 80s. At the start of the study, tests showed they had normal brain function. But 1,162 of them had problems with hearing. Researchers kept track of everyone for about 6 years. They repeated the tests of hearing and brain function 3 times. More than 600 people developed memory or thinking problems. Researchers adjusted their numbers to account for other factors that can increase the risk of mental decline, such as high blood pressure or low education. People with hearing problems were still 24% more likely to develop thinking and memory problems than people with normal hearing. Researchers noted that people who don't hear well may not talk to other people as much. Lack of social contacts is known to increase the risk of mental decline. The jo urnal JAMA Internal Medicine published the study January 22. HealthDay News and USA Today wrote about it.
