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 ... -
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 ... -
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 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 ... -
Early Visual Processing Deficits in Dysbindin-Associated Schizophrenia,
GARAVAN, HUGH PATRICK; ROBERTSON, IAN (Elsevier, 2008)Background: Variation at the dysbindin gene (DTNBP1) has been associated with increased risk for schizophrenia in numerous independent samples and recently with deficits in general and domain-specific cognitive processing. ... -
The effects of a self-alert training (SAT) program in adults with ADHD
ROBERTSON, IAN; O'CONNELL, REDMOND (2015)Attention-Deficit/Hyperactivity Disorder (ADHD), a neuropsychiatric condition characterized by attention and impulsivity problems, is one of the most common behavioral disorders. The first line of treatment for ADHD is ... -
The effects of immunologic brainstem encephalopathy on cognitive function following awakening from a progressive autoimmune coma.
ROBERTSON, IAN; DOCKREE, PAUL; PENDER, NIALL (2014)We describe a unique patient who experienced a progressive autoimmune coma from age 14 to 17. The patient awoke after treatment with immunosuppressant medication. Although alertness, verbalization, and mobilization markedly ... -
The effects of visuomotor feedback training on the recovery of hemispatial neglect symptoms: assessment of a two-week and follow-up intervention
ROBERTSON, IAN (2006)In patients suffering from left unilateral neglect, their right-biased attention to the phenomenal world can be ameliorated, short-term, by making motor responses to left-right extended objects (rods) that immediately ... -
An evaluation of a working memory training scheme in older adults
ROBERTSON, IAN (2013)Working memory is a cognitive process that is particularly vulnerable to decline with age. The current study sought to evaluate the efficacy of a working memory training scheme in improving memory in a group of older adults. ...
