The Stroop is a classical paradigm that presumably involves the inhibition of automatic responses and is frequently used to assess the frontal lobe functions. We investigated the effect of discrete prefrontal lesions in a Stroop task. A sample of 32 patients with frontal lesions were matched with normal controls by sex, age and years of education.(More)
Two limiting factors of dopamine activity are the catechol-o-methyltransferase (COMT) and the dopamine transporter (DAT), which terminate dopamine activity by degradation and uptake, respectively. Genetic variants of COMT and DAT have been related to the enzymatic activity and protein availability, respectively. The Met allele of the COMT Val108/158 Met(More)
Metabolic Syndrome is a cluster of vascular risk factors which has been related to dementia and cognitive decline. The aim of this study was to describe the neuropsychological profile of metabolic syndrome patients. An extensive neuropsychological protocol was administered to 55 patients and 35 controls assessing memory, executive, visuoperceptual and(More)
BACKGROUND Although metabolic syndrome is associated with cardiovascular disease and stroke, limited information is available on specific brain damage in patients with this syndrome. We investigated the relationship of the syndrome with white matter (WM) alteration using a voxel-based approach with diffusion tensor imaging (DTI). METHODS We compared(More)
Similarities and differences between obesity and addiction are a prominent topic of ongoing research. We conducted an activation likelihood estimation meta-analysis on 87 studies in order to map the functional magnetic resonance imaging (fMRI) response to reward in participants with obesity, substance addiction and non-substance (or behavioural) addiction,(More)
Cognitive reserve (CR) is the brain's capacity to cope with cerebral damage to minimize clinical manifestations. The 'passive model' considers head or brain measures as anatomical substrates of CR, whereas the 'active model' emphasizes the use of brain networks effectively. Sixteen healthy subjects, 12 amnestic mild cognitive impairment (MCI) and 16 cases(More)
To examine the relationship between neuropsychological sequelae and atrophy parameters from magnetic resonance imaging (MRI) following paediatric moderate-to-severe traumatic brain injury (TBI), 19 head injured children and adolescents were studied at least 6 years after injury. Three-dimensional MRI scans were obtained. A semi-automatic computerized method(More)
The aim of this paper is to describe the patterns of functional magnetic resonance imaging activation produced by visual food stimuli in healthy participants, as well as in those with anorexia nervosa, bulimia nervosa, binge eating disorder and obesity. We conducted a systematic review of studies published in the last decade on normal and abnormal eating.(More)
In order to investigate the relationship between age at injury and long-term neuropsychological impairment, 29 children and adolescents who sustained traumatic brain injury (TBI) were studied at least 6 years post-trauma. Tests of intellectual, memory, visuospatial and frontal lobe functions were administered to patients and 29 normal matched control(More)
