Adults living with a diagnosis of ADHD or ASD: Different diagnoses, yet similar personal impacts?
(2018)The aim of this study is to provide greater insight into the phenomenon of living with ADHD and/or ASD in adulthood, as directly reported by those who experience the conditions. And, to explore how a late diagnosis, attitudes ... -
Association between dopamine transporter (DAT1)genotype, left sided inattention, and an enhanced response to methylphenidate in attention deficit hyperactivity disorder
(2005)A polymorphism of the dopamine transporter gene (DAT1, 10-repeat) is associated with attention-deficit hyperactivity disorder (ADHD) and has been linked to an enhanced response to methylphenidate (MPH). One aspect of the ... -
Attention Deficit Hyperactivity Disorder (ADHD) and 5-HT2C receptor: A slight increase in the transmission of Cys23 to ADHD cases
(1999)Recent evidence suggests that interaction with and balancebetween serotonergicand dopaminergic neurotransmissionis important in the mediation of hyperactive behaviour.Animal model studies have ®rmly implicated the genes ... -
Decreased frontal, striatal and cerebellar activation in adults with ADHD during an adaptive delay discounting task
(2015)An important characteristic of childhood attention-deficit/hyperactivity disorder (ADHD) is a bias towards small immediate versus larger delayed rewards, but it is not known if this symptom is also a feature of adult ADHD. ... -
Developing creative methods for children's voice research: Potential and pitfalls when constructing verbal and visual methods for research with children with Attention Deficit Hyperactivity Disorder
(SAGE, 2017)‘How does an elephant tell a mouse what it is like to be an elephant?’ replied one young man, when we asked, ‘What is it like to live with attention deficit hyperactivity disorder?’ His observations demonstrate how ... -
Developmental comorbidity assessment in childhood ADHD
(2003)Introduction: Childhood ADHD typically presents with comorbidites. Assessment tools for developmental screening vary greatly in length and complexitity, and parental preference has an impact on the usefulness of clinical ... -
Dissociation in performance of children with ADHD and autism on a task of sustained attention
(2007)Attention deficit hyperactivity disorder (ADHD) and autism are two neurodevelopmental disorders associated with prominent executive dysfunction, which may be underpinned by disruption within fronto-striatal and fronto-parietal ... -
Dissociation in response to methylphenidate on response variability in a group of medication naïve children with ADHD
(2008)Increased variability in reaction time (RT) has been proposed as a cardinal feature of attention deficit hyperactivity disorder (ADHD). Increased variability during sustained attention tasks may reflect inefficient ... -
Do ADHD-impulsivity and BMI have shared polygenic and neural correlates?
(2019)There is an extensive body of literature linking ADHD to overweight and obesity. Research indicates that impulsivity features of ADHD account for a degree of this overlap. The neural and polygenic correlates of this ... -
Dopa decarboxylase gene polymorphisms and attention deficit hyperactivity disorder (ADHD): no evidence for association in the Irish population
(2001)Dopa decarboxylase (DDC) is an enzyme which catalyses the decarboxylation of both dopa to dopamine and L-5 hydroxytryptophan to serotonin. Both catecholamines are major neurotransmitters of the mammalian nervous system. ... -
Evidence that genetic variation in the oxytocin receptor (OXTR) gene influences social cognition in ADHD
(2010)Some children with ADHD also have social and communication difficulties similar to those seen in children with autistic spectrum disorders and this may be due to shared genetic liability. As the oxytocin receptor (OXTR) ... -
Evidence that variation at the serotonin transporter gene influences susceptibility to attention deficit hyperactivity disorder (ADHD): analysis and pooled analysis.
(2002)Reduced central serotonergic activity has been implicated in poor impulse regulation and aggressive behaviour in animals, adults and also young children.1,2 Two recently published studies have implicated variation at a ... -
Executive Function in Routine Childhood ADHD Assessment
(2010)Aims: To determine the metacognitive deficits and behavioural and emotional regulation deficits among a group of children undergoing treatment for ADHD and to compare these with the hyperactivity/inattentive and behavioural ... -
Factors associated with acceptance of peers with mental health problems in childhood and adolescence
(2011)Background: Research suggests that children's reactions to peers with mental health problems are related to the maintenance and outcomes of these problems. However, children's perceptions of such peers, particularly those ... -
fMRI activation during response inhibition and error processing: the role of the DAT1 gene in typically developing adolescents and those diagnosed with ADHD
(2011)The DAT1 gene codes for the dopamine transporter, which clears dopamine from the synaptic cleft, and a variant of this gene has previously been associated with compromised response inhibition in both healthy and clinical ... -
Gendered Expectations on the Recognition of ADHD in Young Women and Educational Implications
(Taylor and Francis Ltd., 2022-02)Although sometimes perceived as a well-known condition, there are numerous aspects of Attention Deficit Hyperactivity Disorder (ADHD) which we do not fully understand. Given the preponderance of previous ADHD research with ... -
Methylphenidate improves some but not all measures of ATTENTION, as measured by the TEA-Ch in medication-naïve children with ADHD
(2013)The Test of Everyday Attention for Children (TEA-Ch) is a reliable neuropsychological assessment of attention control in children. Methylphenidate (MPH) is an effective treatment to improve attentional difficulties in ... -
Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology
(2017)Moment-to-moment reaction time variability on tasks of attention, often quantified by intra-individual response variability (IRV), provides a good indication of the degree to which an individual is vulnerable to lapses in ...
