Altered Brain Activation During a Verbal Working Memory Task in Subjects with Amnestic Mild Cognitive Impairment.
BOKDE, ARUN; HAMPEL, HARALD (2010)In subjects with Mild Cognitive Impairment (MCI) memory disorders indicate a high risk for conversion to Alzheimer?s disease (AD). The objective of this study was to delineate the differences in brain activation between ... -
Association of Protein Phosphatase PPM1G With Alcohol Use Disorder and Brain Activity During Behavioral Control in a Genome-Wide Methylation Analysis.
BOKDE, ARUN (2015)The genetic component of alcohol use disorder is substantial, but monozygotic twin discordance indicates a role for nonheritable differences that could be mediated by epigenetics. Despite growing evidence associating ... -
Brain atrophy in primary progressive aphasia involves the cholinergic basal forebrain and Ayala's nucleus
BOKDE, ARUN (2014)Primary progressive aphasia (PPA) is characterized by left hemispheric fronto-temporal cortical atrophy. Evidence from anatomical studies suggests that the nucleus subputaminalis (NSP), a subnucleus of the cholinergic basal ... -
Brain Regions Related to Impulsivity Mediate the Effects of Early Adversity on Antisocial Behavior
BOKDE, ARUN; WHELAN, ROBERT (2017)Background Individual differences in impulsivity and early adversity are known to be strong predictors of adolescent antisocial behavior. However, the neurobiological bases of impulsivity and their relation to antisocial ... -
Cannabis use in early adolescence: Evidence of amygdala hypersensitivity to signals of threat
BOKDE, ARUN; WHELAN, ROBERT (2015)Cannabis use in adolescence may be characterized by differences in the neural basis of affective processing. In this study, we used an fMRI affective face processing task to compare a large group (n = 70) of 14-year olds ... -
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 ... -
Current Practice in the Referral of Individuals with Suspected Dementia for Neuroimaging by General Practitioners in Ireland and Wales
CIBLIS, AURELIA; BOKDE, ARUN (2016)Objectives While early diagnosis of dementia is important, the question arises whether general practitioners (GPs) should engage in direct referrals. The current study investigated current referral practices for ... -
Diagnostic power of default mode network resting state fMRI in the detection of Alzheimer's disease.
BOKDE, ARUN; HAMPEL, HARALD (2012)Functional magnetic resonance imaging (fMRI) of default mode network (DMN) brain activity during resting is recently gaining attention as a potential noninvasive biomarker to diagnose incipient Alzheimer's disease. The aim ... -
Dimensions of manic symptoms in youth: psychosocial impairment and cognitive performance in the IMAGEN sample.
BOKDE, ARUN (2014)It has been reported that mania may be associated with superior cognitive performance. In this study, we test the hypothesis that manic symptoms in youth separate along two correlated dimensions and that a symptom constellation ... -
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 ... -
Genomic architecture of human neuroanatomical diversity

Global genetic variations predict brain response to faces
BOKDE, ARUN (2014)Face expressions are a rich source of social signals. Here we estimated the proportion of phenotypic variance in the brain response to facial expressions explained by common genetic variance captured by ~500,000 single ... -
Healthy aging is associated with increased neural processing of positive valence but attenuated processing of emotional arousal: an fMRI study
KEHOE, ELIZABETH; BALSTERS, JOSHUA; BOKDE, ARUN (2013)Arousal and valence play key roles in emotional perception, with normal aging leading to changes in the neural substrates supporting valence processing. The objective of this study was to investigate normal age-related ... -
Human subcortical brain asymmetries in 15,847 people worldwide reveal effects of age and sex
WHELAN, ROBERT; GILL, MICHAEL; CORVIN, AIDEN; BOKDE, ARUN; DONOHOE, GARY (2016)The two hemispheres of the human brain differ functionally and structurally. Despite over a century of research, the extent to which brain asymmetry is influenced by sex, handedness, age, and genetic factors is still ... -
Identifying disordered eating behaviours in adolescents: how do parent and adolescent reports differ by sex and age?
WHELAN, ROBERT; BOKDE, ARUN; Bartholdy, Savani; Allen, Karina; Hodsoll, John; O'Daly, Owen G.; Campbell, Iain C.; Banaschewski, Tobias; Bromberg, Uli; Büchel, Christian; Burke Quinlan, Erin; Conrod, Patricia J.; Desrivieres, Sylvane; Flor, Herta; Frouin, Vincent; Gallinat, Jürgen; Garavan, Hugh; Heinz, Andreas; Ittermann, Bernd; Martinot, Jean-Luc; Artiges, Eric; Nees, Frauke; Papadopoulos Orfanos, Dimitri; Paus, Tomáš; Poustka, Luise; Smolka, Michael N.; Mennigen, Eva; Walter, Henrik; Schumann, Gunter; Schmidt, Ulrike (2017)This study investigated the prevalence of disordered eating cognitions and behaviours across mid-adolescence in a large European sample, and explored the extent to which prevalence ratings were affected by informant ... -
Incomplete Hippocampal Inversion: A Comprehensive MRI Study of Over 2000 Subjects.
BOKDE, ARUN; GARAVAN, HUGH; WHELAN, ROBERT (2015)The incomplete-hippocampal-inversion (IHI), also known as malrotation, is an atypical anatomical pattern of the hippocampus, which has been reported in healthy subjects in different studies. However, extensive characterization ...
