Noise may impact brains of adults, cause difficulty in functioning: Study


Higher levels of noise may impact the brains of older adults, making it difficult to work without help, suggested a study.


The study, which was published in the journal Alzheimer's & Dementia further suggested that it might also influence individuals' risk of developing dementia later in life.

Researchers studied 5,227 participants of the Chicago Health and Aging Project who were aged 65 years or older, of whom 30 per cent had mild cognitive impairment and 11 per cent had Alzheimer's disease. 

After the study, they found that persons living with 10 decibels more noise near their residences during the daytime had a 36 per cent higher odds of having a mild cognitive impairment and a 30 per cent higher odds of having Alzheimer's disease.

The findings suggest that within typical urban communities in the United States, higher levels of noise may impact the brains of older adults and make it harder for them to function without assistance.
