Research discovers link between hearing loss and cognitive decline. Recent findings show this new association which indicates risk of dementia and other diseases.
During the study, the researchers from Brigham and Women’s Hospital and Harvard Medical School, both in Boston, MA analyzed 8 years of data from a study of more than 10,000 men. They found that hearing loss is associated with subjective cognitive decline risk. The data was retrieved from the Health Professionals Follow-Up Study (HPFS).
The team explains that subjective cognitive decline risk was 30 percent higher among men with hearing loss than those who are free from hearing loss. The risk was between 42 and 54 percent higher in men with moderate or severe hearing loss.
“Our findings show that hearing loss is associated with new onset of subjective cognitive concerns which may be indicative of early-stage changes in cognition,” lead study author Dr. Sharon Curhan, said. He works as a physician and epidemiologist.
According to the World Health Organization (WHO), around 50 million people worldwide have dementia and the number is predicted to rise to 75 million by 2030. currently, there is no cure for the disease. However, new study reveals that early diagnosis can help to increase lifespan for people with dementia.
Latest findings suggest that subjective cognitive function can cause mild cognitive impairment and predementia.
“We plan to conduct further longitudinal studies of the relation of hearing loss and cognition in women and in younger populations, which will be informative,” Dr. Sharon Curhan said.
