Abstract:

Sickle Cell Disease (SCD) is a collection of genetic haemoglobinopathies, the most common and severe being homozygous sickle cell anaemia. In the UK, it has been estimated that 1 in 2000 children are born with SCD. The disease is characterised by chronic anaemia, recurrent pain crises and vascular occlusion. Neurologically, there is a high incidence of stroke in childhood, as well as cognitive dysfunction. Newborn screening programmes and preventative treatments have allowed a much longer lifespan; however recently, neurological research has shifted to characterising subtler aspects of brain d

Los trabajos incluidos en esta tesis van sobre el tema de la correlación clínico patológica en la enfermedad neurodegenerativa y más específicamente en la afasia primaria progresiva (APP). En el primer trabajo analizamos la proporción de positividad PET-amiloide en cada variante clínica para probar la hipótesis que clasificación según los criterios diagnósticos actuales (establecidos por consenso en 2011) de afasia primaria progresiva resultaría en grupos patológicamente homogéneos. Esta clasificación resulto ser altamente predictiva del estado del biomarcador de amiloide, en particular, la v

Abstract:

The primary tauopathies are a group of neurodegenerative diseases affecting movement and cognition. In this thesis I study Progressive Supranuclear Palsy (PSP) and the Corticobasal Syndrome (CBS), two parkinsonian disorders associated with accumulation of hyperphos- phorylated and abnormally folded tau protein. I contrast these two disorders with Parkinson’s disease (PD), which is associated with the accumulation of alpha-synuclein but has a genetic association with the MAPT gene encoding tau. Understanding the tauopathies to develop effective treatments will require a better grasp of the rela

Les maladies par expansion de polyglutamines sont des maladies neurodégénératives dues à l’expansion du trinucléotide cytosine-adénine-guanine (CAG) dans les gènes correspondants codant pour une expansion d’homopolymère de glutamine dans les protéines mutées. Ce projet concerne les formes les plus courantes qui sont la maladie de Huntington (MH) et les ataxies spinocérébelleuses (SCA) types 1, 2, 3 et 7. Ce sont des maladies autosomiques dominantes, responsables de troubles graves de la motricité partageant des voies physiopathologiques communes, avec un effet notable sur la dysfonction métabo

Abstract:

The Apolipoprotein E (APOE) ε4 allele is the best-established genetic risk factor for sporadic Alzheimer's disease (AD) while the ε2 allele confers a reduced risk compared with the most common ε3 allele. Neuroimaging studies using magnetic resonance imaging (MRI) have shown that APOE genotype affects brain structure and function. The aims of the research presented in this DPhil thesis were twofold: 1) to investigate the effect of APOE genotype on brain function in healthy adults using magnetoencephalography (MEG), which is a direct measure of neuronal activity and 2) to explore interactions be

Abstract:

Introduction: Small vessel disease is the underlying cause of most spontaneous (non-traumatic) ICH. Cerebral imaging markers of small vessel disease, particularly cerebral microbleeds (CMBs) and white matter hyperintensities of presumed vascular origin (WMH) offer clinicians and researchers an opportunity to further understand the pathogenesis and risk of ICH in patients with stroke. In this thesis I present a portfolio of studies aimed to show the clinical relevance of neuroimaging biomarkers of small vessel disease in relation to intracerebral haemorrhage (ICH). Methods: I ascertained patien

Abstract:

Parkinson’s disease (PD) is the neurological disease with the fastest growing rate. 1% of the world population over 60 years have a PD diagnosis. PD presents a complex and heterogenous clinical picture during the disease course, and dementia represents the most severe condition. This thesis investigates the neurobiological mechanisms and cognitive features of PD patients with a severe clinical phenotype – developing cognitive deterioration, reaching dementia condition. The studies included in this dissertation contributed to identifying risk factors, biomarkers, cognitive features, and sources

Abstract:

Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease of the central nervous system (CNS) that is associated with progressive neurodegeneration. To better understand the dynamics of disease progression in individuals with MS, and to personalise treatment strategies, the development of quantitative in-vivo biomarkers is critical. Magnetic resonance imaging (MRI) is an essential technique that has been successfully embedded in the formal diagnostic criteria for MS since 2001. Conventional MRI techniques facilitate the demonstration of lesion dissemination in both space and tim

Au fil des ans, l'Imagerie par Résonance Magnétique (IRM) a été de plus en plus utilisée pour mieux comprendre les anomalies structurelles et fonctionnelles inhérentes à ce trouble. Les progrès récents en apprentissage automatique et l'apparition de larges bases de données ouvrent maintenant la voie vers la découverte de biomarqueurs pour le diagnostic/ pronostic assisté par ordinateur.

Abstract:

My thesis consisted of two studies. The first study was a part of a wider study; within this, we investigated the modulation of amygdala structure by the val66met BDNF (Brain Derived Neurotrophic Factor) polymorphism. Structural Magnetic Resonance Imaging (MRI) scans were obtained at 1.5 T in 87 Major Depressive Disorder (MDD) patients and 74 age, gender, and verbal IQ matched healthy controls. We used Freesurfer version 5.1.0 to examine the grey matter amygdala volume. In the second study, we investigated neuroendocrine abnormalities˗˗ Hypothalamus-Pituitary-Adrenal Axis (HPA) axis changes˗˗
