Elderly people living in noisy neighborhoods are in a higher risk of developing dementia and Alzheimer’s disease according to a new study published in the journal, “Alzheimers & Dementia”. Data from 5,227 people ages 65 years old and above who were participants of the “Chicago Health and Aging project” were assessed. Researchers found out that older people living with 10 decibels more noise in their residents had a higher chance of brain deterioration and 30% higher risk of getting Alzheimer’s disease.

The study’s senior author Sara D. Adar from University of Michigan School of Public Health said that typical urban communities in the U.S. have higher levels of noise that may impact the brain of older adults. In an earlier study from 2015, experts found that laboratory rats exposed to chronic noise have an increased production of beta-amyloid, a protein that plays an important role in Alzheimer’s disease. Noise exposure can have a serious impact on health, affecting sleep and blood pressure levels that can increase dementia risk. Researchers hope that the study would urge lawmakers to change some policies regarding noise level reduction in communities.
