Utilidad de la resonancia magnética en contraste de fase en el diagnóstico de las patologías relacionadas con trastorno en la circulación del liquido cefalorraquideo.

Description: El objetivo principal de esta tesis es estudiar la circulación del LCR y la patología relacionada con la misma mediante una técnica de neuroimagen no invasiva.

La Resonancia Magnética inicialmente permitía realizar estudios estructurales cerebrales de alta resolución, pero no estudios funci...

Advanced and convencional magnetic resonance imaging in neuropsychiatric lupus.

Description: Neuropsychiatric lupus is a major diagnostic challenge, and a main cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Magnetic resonance imaging (MRI) is, by far, the main tool for assessing the brain in this disease. Conventional and advanced MRI techniques are us...

Integrating genetic, neuropsychological and neuroimaging data to model early-onset obsessive compulsive disorder severity

Description: We propose an integrative approach that combines structural magnetic resonance imaging data (MRI), diffusion tensor imaging data (DTI), neuropsychological data, and genetic data to predict early-onset obsessive compulsive disorder (OCD) severity. From a cohort of 87 patients, 56 with complete inform...

Functional networks and structural connectivity of visuospatial and visuoperceptual working memory

Description: Neural correlates of working memory (WM) in healthy subjects have been extensively investigated using functional MRI (fMRI). However it still remains unclear how cortical areas forming part of functional WM networks are also connected by white matter fiber bundles, and whether DTI measures, used as ...

Motor and cortico-striatal-thalamic connectivity alterations in intrauterine growth restriction

Description: BACKGROUND: Intrauterine growth restriction is associated with short-and long-term neurodevelopmental problems. Structural brain changes underlying these alterations have been described with the use of different magnetic resonance-based methods that include changes in whole structural brain networks...

Altered resting-state whole-brain functional networks of neonates with intrauterine growth restriction

Description: The feasibility to use functional MRI (fMRI) during natural sleep to assess low-frequency basal brain activity fluctuations in human neonates has been demonstrated, although its potential to characterise pathologies of prenatal origin has not yet been exploited. In the present study, we used intraut...

Dynamic funcitonal reorganizations and relationships with working memory performance in healthy aging

Description: In recent years, several theories have been proposed in attempts to identify the neural mechanisms underlying successful cognitive aging. Old subjects show increased neural activity during the performance of tasks, mainly in prefrontal areas, which is interpreted as a compensatory mechanism linked t...

Birth weight and adult IQ, but not anxious-depressive psychopathology, are associated with cortical surface area: a study in twins.

Description: Background Previous research suggests that low birth weight (BW) induces reduced brain cortical sur- face area (SA) which would persist until at least early adulthood. Moreover, low BW has been linked to psychiatric disorders such as depression and psychological distress, and to altered neurocogniti...

Environmental factors inducing depression alter the cerebellar resting-state synchronization.

Description: Hosting nearly eighty percent of all human neurons, the cerebellum is functionally connected to large regions of the brain. Accumulating data suggest that some cerebellar resting-state alterations may constitute a key candidate mechanism for depressive psychopathology. While there is some evidence l...

White Matter Abnormalities Track Disease Progression in PSEN1 Autosomal Dominant Alzheimer's Disease

Description: PSEN1 mutations are the most frequent cause of autosomal dominant Alzheimer's disease (ADAD), and show nearly full penetrance. There is presently increasing interest in the study of biomarkers that track disease progression in order to test therapeutic interventions in ADAD. We used white mater (WM)...
