Abstract
Allergic tendencies are associated with important cognitive and physiological factors, such as intelligence and mathematical abilities. Allergies are widely prevalent, especially in modern life, and the reason for its association with important cognitive variables is an intriguing scientific question. However, despite the unique characteristics of cognitive correlates of allergy, the anatomical correlates of allergy remain unknown. The aim of this study was to identify the associations between regional gray matter volume (rGMV) and allergic tendencies in young adults. In a study cohort of 1,219 healthy, educated young adults, we identified a positive correlation between total allergic tendency and rGMV in large anatomical clusters that mainly encompassed the dorsal part of the cerebral neocortex, right anterior insula, and cerebellum. Furthermore,both mean rGMV of the entire part of these clusters and total allergenic tendency showed a significant positive correlation with spatial ability. These results suggest the link among allergic tendencies, larger rGMV, and the better spatial ability in healthy, educated young adults.

Allergic tendencies are associated with important cognitive and physiological factors, such as intelligence and mathematical abilities
Consistent with our hypothesis, our novel findings showed that overall allergic tendencies were associated with a greater regional gray matter volume (rGMV) in extensive cortical areas, especially in the dorsal part of the cerebral neocortex, right anterior insula, and cerebellum
Allergic tendencies showed a positive correlation with spatial ability
Summary
Allergic tendencies are associated with important cognitive and physiological factors, such as intelligence and mathematical abilities. Both mean rGMV of the entire part of these clusters and total allergenic tendency showed a significant positive correlation with spatial ability These results suggest the link among allergic tendencies, larger rGMV, and the better spatial ability in healthy, educated young adults. Allergic tendencies (the degree to which one shows symptoms of certain types of allergies) are associated with a number of important physiological and cognitive factors. Despite the unique characteristics of cognitive correlates of allergy, and traditional theory linking spatial abilities and brain development[5], the anatomical correlates of allergy remain unknown
