Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. Inattentiveness, overactivity, and impulsiveness are presently regarded as the main clinical symptoms. The dynamic developmental behavioral theory is based on the hypothesis that altered dopaminergic function plays a pivotal role by failing to modulate nondopaminergic (primarily glutamate and GABA) signal transmission appropriately.

Origins of altered reinforcement effects in ADHD

Theoretical and experimental analyses of these moderating factors will help to determine just how reinforcement processes are altered in ADHD, and can only help to improve treatment strategies for ADHD.

Brain functional domains inform therapeutic interventions in attention-deficit/hyperactivity disorder and pediatric bipolar disorder

The reward-related mechanisms underlying the interactions between executive function, behavior regulation and impulsivity in PBD and ADHD may be differentially compromised, and in accordance differently shape the clinical symptoms of impulsivity and goal-directed behavior.

An integrative theory of attention-deficit/ hyperactivity disorder based on the cognitive and affective neurosciences

Attention-deficit/hyperactivity disorder (ADHD) is a behavioral syndrome that arises in early childhood, often co-occurs with conduct disorder and leads, developmentally, to antisocial behavior and

Frontal Dysfunctions of Impulse Control – A Systematic Review in Borderline Personality Disorder and Attention-Deficit/Hyperactivity Disorder

Overall, patients with BPD exhibited prefrontal dysfunctions across impulse control components rather in orbitofrontal, dorsomedial, and dorsolateral prefrontal regions, whereas patients with ADHD displayed disturbed activity mainly in ventrolateral and medial prefrontal regions.

Attention deficit/hyperactivity disorder--from brain dysfunctions to behaviour.

The combined insights of the articles presented here suggest that there is no brain damage in ADHD, but hypo-efficient dopamine systems which give rise to neurochemical imbalances which cause behavioural problems: deficits in sustained attention, overactivity and impulsiveness.

Functional deficits in basal ganglia of children with attention-deficit/hyperactivity disorder shown with functional magnetic resonance imaging relaxometry

A new functional magnetic resonance imaging procedure (T2 relaxometry) was developed to indirectly assess blood volume in the striatum (caudate and putamen) of boys 6–12 years of age in steady-state conditions and found boys with attention-deficit/hyperactivity disorder had higher T2 relaxation time measures in the putamen bilaterally than healthy control subjects.

This formulation emphasizes the need for several types of research: the mapping of biological findings onto different components of disorder, the combination of genetically informative designs with direct measurement of relevant aspects of the environment, and the use of longitudinal studies to examine predictive and mediating factors separately for different aspects of outcome.

A theoretical model that links inhibition to 4 executive neuropsychological functions that appear to depend on it for their effective execution is constructed and finds it to be strongest for deficits in behavioral inhibition, working memory, regulation of motivation, and motor control in those with ADHD.
