Background: Bisphenol A (BPA) has been linked to attention-deficit/hyperactivity disorder (ADHD) symptoms,
but the effects on cognitive functions and functionality in adult ADHD have not been investigated. We investigated
the associations between serum BPA with cognitive functions and functionality in adult ADHD patients.
Methods: The levels of BPA were measured in 45 adult ADHD patients and 45 well-matched healty controls. The
relationship between plastic exposure and BPA was also evaluated. Stroop test and Wisconsin Card Sorting Test
were applied for neurocognitive evaluation and participants were compared in basic cognitive functions
including planning, organization, abstraction, problem solving, strategy development, set shifting, cognitive
flexibility, variants of attention, information processing speed, the ability to change perceptual setup and
response under interference. Sheehan disability scale was applied for functionality. The association of BPA with
test scores was analyzed statistically.
Results: Serum BPA levels in adult ADHD patients were found to be significantly higher than in healthy controls.
There was no relationship between plastic exposure and BPA levels. BPA levels showed a significant effect on
functionality in terms of work field. There were significant differences between the groups in terms of cognitive
functions. However, no significant correlation was found between BPA levels and cognitive functions.
Conclusions: BPA is associated with ADHD and affects functionality in the field of work, but larger-scale further
studies are needed for its effect on cognitive functions.
