BACKGROUND Patients with attention-deficit/hyperactivity disorder (ADHD) show episodic memory deficits especially in complex memory tasks. We investigated the neural correlates of memory formation in ADHD and their modulation by stimulus salience. METHODS We recorded event-related functional magnetic resonance imaging during an episodic memory paradigm with neutral and emotional pictures in 12 male ADHD subjects and 12 healthy adolescents. RESULTS Emotional salience did significantly… Expand
Sleep Promotes Consolidation of Emotional Memory in Healthy Children but Not in Children with Attention-Deficit Hyperactivity Disorder
TLDR
An increased sleep-dependent emotional memory bias in healthy children compared to children with ADHD and healthy adults is observed and this data indicate a decline in sleep-related consolidation of emotional memory in healthy development. Expand
Enhanced gamma-band activity in ADHD patients lacks correlation with memory performance found in healthy children
TLDR
Analysis of evoked gamma-band responses (GBRs) during stimulus encoding revealed a strong task-related enhancement for ADHD patients in parieto-occipital areas, which is interpreted as evidence of enhanced excitation levels and unspecific activation of processing resources in ADHD patients. Expand
Electrophysiological correlates of semantic processing during encoding of neutral and emotional pictures in patients with ADHD
TLDR
Findings provide evidence that ADHD patients show deficits in translating pre-stimulus mobilization of neural resources to successful memory formation in the absence of salient stimulus material. Expand
Reduced sleep-associated consolidation of declarative memory in attention-deficit/hyperactivity disorder.
TLDR
The results suggest reduced functionality of slow oscillations in sleep-associated consolidation of declarative memory in ADHD, which is in line with previous reports on sleep-related deficits in attention-deficit/hyperactivity disorder. Expand
Sleep restores daytime deficits in procedural memory in children with attention-deficit/hyperactivity disorder.
TLDR
It is suggested that sleep in ADHD normalizes deficits in procedural memory observed during daytime, and in patients with ADHD attenuated prefrontal control enables sleep-dependent gains in motor skills by reducing the competitive interference between explicit and implicit components within a motor task.

The Status of Structural and Functional MRI in Adolescents with Attention-Deficit/Hyperactivity Disorder
Neuroimaging has been widely used to evaluate the structural and functional integrity of the brain in persons with attention-deficit/hyperactivity disorder (ADHD) across the lifespan. Despite theExpand
Magnetic Resonance Spectroscopy Studies of Attention Deficit Hyperactivity Disorder
TLDR
A speculative cortical glutamate-based cingulocentric model of ADHD is offered that seeks to explain its dynamic symptomatic phenomenology in MRS-relevant neurochemical terms and is compatible with the astroglial brain-energy deficiency hypothesis of ADHD. Expand

Hyperresponsiveness to social rewards in children and adolescents with attention-deficit/hyperactivity disorder (ADHD)
TLDR
The findings provide evidence for hyperresponsiveness to social rewards in ADHD patients, which is accompanied by limited self-awareness, and suggest that social reward procedures may be particularly useful in behavioral interventions in children with ADHD. Expand
A comprehensive investigation of memory impairment in attention deficit hyperactivity disorder and oppositional defiant disorder.
TLDR
The data suggest that verbal memory difficulties are more closely associated with ODD than ADHD symptoms and that combined ADHD+ODD represents a true comorbidity, and support a small but growing number of suggestions in the literature of impaired LTM in ADHD. Expand

Dysfunctional Attentional Networks in Children with Attention Deficit/Hyperactivity Disorder: Evidence from an Event-Related Functional Magnetic Resonance Imaging Study
TLDR
For alerting and executive attention, the data indicate a deviant mechanism of cortical control, while ADHD children may have adopted altered strategies for reorienting of attention. Expand
Alterations in the functional anatomy of working memory in adult attention deficit hyperactivity disorder.
TLDR
The use of compensatory mental and neural strategies by subjects with ADHD in response to a disrupted ability to inhibit attention to nonrelevant stimuli and the use of internalized speech to guide behavior are suggested. Expand
Event-related FMRI evidence of frontotemporal involvement in aberrant response inhibition and task switching in attention-deficit/hyperactivity disorder.
TLDR
It is suggested that underactivation in frontal regions reflects core deficits in response/task-switching abilities for the ADHD group. Expand
Functional neuroanatomy of working memory in adults with attention-deficit/hyperactivity disorder
TLDR
The findings suggest that the cerebellum is involved in the pathophysiology of at least some cognitive deficits associated with ADHD and emphasize the need for additional research aimed at elucidating the role of the Cerebellum in ADHD symptomatology. Expand
Hypofrontality in attention deficit hyperactivity disorder during higher-order motor control: a study with functional MRI.
TLDR
Functional magnetic resonance imaging was used to investigate the hypothesis that attention deficit hyperactivity disorder (ADHD) is associated with a dysfunction of prefrontal brain regions during motor response inhibition and motor timing, and hyperactive adolescents showed lower power of response.

TLDR
The schizophrenic group showed the most pronounced deficits on tests of abstraction, visual memory, and motor function in comparison with the subjects with ADHD, while the ADHD subjects had the most pronouncement of deficits on measures of attention, verbalmemory, and learning. Expand
Functional MRI in attention-deficit hyperactivity disorder: Evidence for hypofrontality
TLDR
Findings are consistent with prior findings of hypofrontality in ADHD children and implicate a compensatory network including basal ganglia, insula and cerebellum for relative lower cognitive load tasks. Expand
Implication of right frontostriatal circuitry in response inhibition and attention-deficit/hyperactivity disorder.
TLDR
The data suggest a role of the right prefrontal cortex in suppressing responses to salient, but otherwise irrelevant events while the basal ganglia appear to be involved in executing these behavioral responses. Expand
Implicit Memory Development in School-Aged Children With Attention Deficit Hyperactivity Disorder (ADHD): Conceptual Priming Deficit?
TLDR
Examination of performance on multiple measures of implicit and explicit memory in children aged 7 to 14 years with and without ADHD found that ADHD and non-ADHD groups performed similarly on tests of explicit memory and on perceptual aspects of implicit memory. Expand
Differential patterns of striatal activation in young children with and without ADHD
TLDR
It is shown that children without ADHD have increased susceptibility to interference with increasing numbers of go trials preceding a nogo trial, but children with ADHD have difficulty even with a single go trial preceding anogo trial. Expand
