Older people living in noisy communities are more likely to get diseases like dementia and Alzheimer’s according to a research published in the “Alzheimers & Dementia” journal. The scientists collected data from 5,227 participants ages 65 years old and above. They found that elderly people living with 10 decibels higher noise in their community had a 30% higher chance of getting dementia. The research team led by senior author Sara D. Adar hopes that lawmakers change policies about reducing noise levels in communities.
