Altered reward processing has been proposed to contribute to the symptoms of attention deficit hyperactivity disorder (ADHD). The neurobiological mechanism underlying this alteration remains unclear. We hypothesize that the transfer of dopamine release from reward to reward-predicting cues, as normally observed in animal studies, may be deficient in ADHD. Functional magnetic resonance imaging (fMRI) was used to investigate striatal responses to reward-predicting cues and reward delivery in a…

Reward modality modulates striatal responses to reward anticipation in ADHD: Effects of affiliative and food stimuli

Children with ADHD symptoms show decreased activity in ventral striatum during the anticipation of reward, irrespective of ADHD diagnosis

Evidence of biological and behavioral differences in reward sensitivity in children with ADHD symptoms, regardless of their primary diagnosis is provided and a dimensional brain-behavior model of reward sensitivity may be useful to refine treatment options dependent on reward processing.

Reward Processing Deficits During a Spatial Attention Task in Patients With ADHD: An fMRI Study

The present findings indicate that ADHD is associated with difficulty integrating reward contingency information with the orienting and regulatory phases of attention.

Attenuated Anticipation of Social and Monetary Rewards in Autism Spectrum Disorders

The results do not support current theories linking atypical social interaction in ASD to specific alterations in processing of social rewards, and point towards a generalized hypoactivity of VS in ASD during anticipation of both social and monetary rewards.

High reward expectancy during methylphenidate depresses the dopaminergic response to gain and loss

It is suggested that striatal tonic dopamine levels constitute an average reward expectation signal that modulates the phasic dopaminergic response to reward, which offers opportunities for treatment of behavioral disorders associated with abnormal reward sensitivity.

Association between uncontrolled eating and caudate responses to reward cues

The current findings provide support for heightened reward anticipation as a neural phenotype contributing to overeating in normal-weight individuals.

Disrupted reinforcement learning during post-error slowing in ADHD

This work separate error detection from magnitude related adjustment (post-error slowing) during inhibition errors in the stop signal task in typically developing and ADHD adolescents using fMRI, and predicted that ventral striatum would instead correlate with heightened amygdala responses to errors.

Reward processing in male adults with childhood ADHD—a comparison between drug-naïve and methylphenidate-treated subjects

Differences in reward processing in adulthood (independent of actual ADHD) depending on MPH treatment during childhood are examined to give evidence for more pronounced abnormal activation in reward-associated brain regions in untreated subjects with childhood ADHD and underpin the need of prospective studies on long-term effects of psychostimulant treatment.

Evaluating dopamine reward pathway in ADHD: clinical implications.

A reduction in dopamine synaptic markers associated with symptoms of inattention was shown in the dopamine reward pathway of participants with ADHD.

Mesolimbic Functional Magnetic Resonance Imaging Activations during Reward Anticipation Correlate with Reward-Related Ventral Striatal Dopamine Release

Evidence is provided that dopaminergic neurotransmission plays a quantitative role in human mesolimbic reward processing and the combined neurochemical and hemodynamic imaging approach used here opens up new perspectives for the investigation of molecular mechanisms underlying human cognition.

The Role of Ventral Frontostriatal Circuitry in Reward-Based Learning in Humans

It is shown that the nucleus accumbens, thalamus, and orbital frontal cortex are each sensitive to reward magnitude, with the Accumbens showing the greatest discrimination between reward values.

The hypothesis that children with ADHD are unusually sensitive to pre- and post-reward delays is supported.
