Abstract: | Attention-deficit hyperactivity disorder ( ADHD) is characterized by pervasive
and impairing symptoms of inattention, hyperactivity, and impulsivity, being one
of the most common neuropsychiatric disorders with childhood onset. Since the
latter part of 1990’s, it has been hypothesized that ADHD symptoms are caused by
neuropsychological dysfunction, namely executive dysfunction, specifically behavioral
dysinhibition. Dopaminergic dysregulation in dorsolateral prefrontal cortex (DLPFC)
is thought to be involved in these dysfunctions. But recent studies indicate ADHD
symptoms may also occur from serotonergic dysregulation. In this case, oppositional
defiant disorder (ODD) and conduct disorder (CD) are highly comorbid with ADHD,
and SSRI can have more effect on the symptoms than metylphenidate hydrochlorine
(MPH) or amphetamine. In the present review, the author looked into extant evidences
with regard to “impulsivity” as multifaceted construct, and concluded that, while pure
ADHD may be caused by behavioral dysinhibition ( impulsivity without emotional
urgency), ADHD with ODD or CD may be caused by impulsivity with emotional
urgency. |
