Associations between ambient pollen exposure and measures of cognitive performance.

ABSTRACT:

Background

Prior research suggests pollen allergies may be associated with cognitive function, although the effect sizes and specific cognitive outcomes varied across studies. With pollen seasons starting earlier and intensifying due to climate change, understanding the effects of pollen exposure on cognition is increasingly relevant. This study investigated the relationship between ambient pollen exposure and cognitive performance in Swiss adults.

Methods

Four cognitive assessments were used to measure the daily performance of 392 participants (299 with pollen allergies) over a 10-day period during pollen season. We used generalized additive mixed models to assess the exposure-response relationship between individualized pollen exposure and cognitive performance, as well as
