Association between dopamine transporter (DAT1) genotype, left-sided inattention, and an enhanced response to methylphenidate in attention deficit hyperactivity disorder (ADHD)
ROBERTSON, IAN (2005)A polymorphism of the dopamine transporter gene (DAT1, 10-repeat) is associated with ADHD and has been linked to an enhanced response to methylphenidate (MPH). One aspect of the attention deficit in ADHD includes a subtle ... -
Association between dopamine transporter (DAT1)genotype, left sided inattention, and an enhanced response to methylphenidate in attention deficit hyperactivity disorder
GILL, MICHAEL; HAWI, ZIARIH; ROBERTSON, IAN; FITZGERALD, MICHAEL (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 ... -
Atrial fibrillation and cognitive function: a case control study
ROBERTSON, IAN (2005)Atrial fibrillation is an important and independent risk factor for cerebrovascular disease and vascular dementia. There is increasing evidence that atrial fibrillation is associated with an increased risk of asymptomatic ... -
Awareness of Deficits in Traumatic Brain Injury: A Multidimensional Approach to Assessing Metacognitive Knowledge and Online-Awareness
ROBERTSON, IAN; DOCKREE, PAUL MICHAEL (Cambridge University Press, 2007)Recent models of impaired awareness in brain injury draw a distinction between metacognitive knowledge of difficulties and online awareness of errors (emergent and anticipatory). We examined performance of 31 Traumatic Brain ... -
BOLD frequency power indexes working memory performance
ROBERTSON, IAN; BALSTERS, JOSHUA (2013)Electrophysiology studies routinely investigate the relationship between neural oscillations and task performance. However, the sluggish nature of the BOLD response means that few researchers have investigated the spectral ... -
Cerebellum and cognition: Evidence for the encoding of higher order rules
BALSTERS, JOSHUA; ROBERTSON, IAN (2013)Converging anatomical and functional evidence suggests that the cerebellum processes both motor and nonmotor information originating from the primary motor cortex and prefrontal cortex, respectively. However, it has not ... -
Change in perceived stress and 2-year change in cognitive function among older adults: The Irish Longitudinal Study on Ageing
KENNY, ROSE; FEENEY, JOANNE; ROBERTSON, IAN (Wiley, 2018)Prolonged or severe stress can adversely affect older adults' cognitive function, but population‐based studies investigating this relationship over time are rare. Previous studies have largely focused on stress either ... -
Changes in resting connectivity with age: A simultaneous electroencephalogram and functional magnetic resonance imaging investigation.
O'CONNELL, REDMOND; ROBERTSON, IAN; BOKDE, ARUN; NOLAN, HUGH (2013)Resting fluctuations in the blood oxygenation level-dependent signal have attracted considerable interest for their sensitivity to pathological brain processes. However, these analyses are susceptible to confound by nonneural ... -
Cognitive neuroscience and brain rehabilitation: a promise kept
ROBERTSON, IAN (2006) -
Cognitive rehabilitation in the elderly: A randomized trial to evaluate a new protocol.
ROBERTSON, IAN (Cambridge University Press, 2007)This study provides an introduction to, and overview of, several papers that resulted from a randomized control trial that evaluated a new cognitive rehabilitation protocol. The program was designed to improve general ... -
Cognitive rehabilitation in the elderly: Effects on strategic behavior in relation to goal management
ROBERTSON, IAN (Cambridge University Press, 2007)Executive functions are highly sensitive to the effects of aging and other conditions affecting frontal lobe function. Yet there are few validated interventions specifically designed to address executive functions, and, ... -
Cognitive rehabilitation in the elderly: overview and future directions.
ROBERTSON, IAN (Cambridge Univeristy Press, 2007)This study provides an overview of the papers emanating from the experimental trial that evaluated a new cognitive rehabilitation program in older adults who were experiencing normal cognitive decline. The main features ... -
Cognitive Rehabilitation Interventions for Neglect and Related Disorders: Moving from Bench to Bedside in Stroke Patients
ROBERTSON, IAN (MIT Press, 2006)The spatial neglect syndrome, defined by asymmetric attention and action not attributed to primary motor or sensory dysfunction and accompanied by functional disability, is a major cause of post-stroke morbidity. In ... -
Dissociation in performance of children with ADHD and autism on a task of sustained attention
JOHNSON, KATHERINE; ROBERTSON, IAN; GALLAGHER, LOUISE; GILL, MICHAEL; BELLGROVE, MARK; FITZGERALD, MICHAEL (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 performance of children with ADHD and high-functioning autism on a task of sustained attention.
GALLAGHER, LOUISE; GILL, MICHAEL; JOHNSON, KATHERINE ANNE; ROBERTSON, IAN (Elsevier, 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
JOHNSON, KATHERINE; ROBERTSON, IAN; GILL, MICHAEL; DAIBHIS, AOIFE; DALY, MICHAEL; FITZGERALD, MICHAEL (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 antisaccade deficits in schizophrenia provide evidence of a specific inhibitory function?
GARAVAN, HUGH PATRICK; ROBERTSON, IAN; CORVIN, AIDEN PETER; MORRIS, DEREK WILLIAMS; DONOHOE, GARY (JAMES) (Cambridge University Press, 2006)Background: Despite its inhibitory control requirements, antisaccade deficits have been consistently associated with working memory impairments in schizophrenia. We investigated whether variance in antisaccade per formance ... -
Donepezil Impairs Memory in Healthy Older Subjects: Behavioural, EEG and Simultaneous EEG/fMRI Biomarkers
FAGAN, ANDREW; CASSIDY, SARAH; ROBERTSON, IAN; BALSTERS, JOSHUA; O'CONNELL, REDMOND; LAWLOR, BRIAN; KILCULLEN, SOPHIA; DELMONTE, SONJA; BRENNAN, SABINA; MEANEY, JAMES; BOKDE, ARUN; BRENNAN, SABINA (2011)Rising life expectancies coupled with an increasing awareness of age-related cognitive decline have led to the unwarranted use of psychopharmaceuticals, including acetylcholinesterase inhibitors (AChEIs), by significant ... -
