Air Pollution Exposure Linked to Memory Decline in Older Adults

Source: PsyPostA recent study provides evidence that long-term exposure to fine particulate air pollution may negatively affect specific types of memory in older adults. The research suggests that breathing polluted air over the course of more than a decade tends to harm semantic memory, which is the brain's ability to recall general knowledge and facts. These findings may help explain why there are racial disparities in dementia risk in the United States.
