Inhabitant

Researchers at the University of Washington have found a relationship between increased levels of fine particle pollution and the risk of dementia. In a study that borrowed data from two long-running studies in the Seattle area, researchers established that high levels of particulate matter in the environment corresponded with a greater risk of dementia
