Abstract: Attention deficit hyperactivity disorder (ADHD)
symptoms are normally distributed in the general population .
In clinical practice ADHD-symptoms may be divided into nonemotional
symptoms (inattention/hyperactivity) and emotional
dysregulation symptoms. Some brain regions, such as caudal
anterior cingulate cortex (cACC) and dorsolateral prefrontal cortex
(dlPFC), are involved in cognitive control of non-emotional processes,
e.g. classical executive functions . Other regions, including
lateral orbitofrontal cortex (lObfc) and rostral anterior cingulate
cortex (rACC), are involved in emotional regulation [3,4]. We
hypothesized that subclinical symptoms related to non-emotional
dysregulation would correlate negatively with cACC and dlPFC
volume as well as non-emotional impulsivity control ability.
Moreover, we hypothesized that subclinical symptoms related to
emotional dysregulation would correlate negatively with lObfc and
rACC volume and positively with tendency to discount the value
of delayed rewards.
