FULL STORY ========================================================================== Results from a new study published in Alzheimer's & Dementia support
emerging evidence suggesting that noise may 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% had mild cognitive impairment and 11% had Alzheimer's disease. They found that persons
living with 10 decibels more noise near their residences during the
daytime had a 36% higher odds of having mild cognitive impairment and
a 30% higher odds of having Alzheimer's disease.

"These 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. This is
an important finding since millions of Americans are currently impacted
by high levels of noise in their communities," said senior author Sara
D. Adar, ScD, of the University of Michigan School of Public Health, Ann
Arbor. Professor Adar added that "although noise has not received a great
deal of attention in the United States to date, there is a public health opportunity here as there are interventions that can reduce exposures
both at the individual and population level." The study was supported
by grants from the Alzheimer's Association and the National Institute
on Aging.
