Diffusion MRI measured white matter microstructure as a biomarker of neurodegeneration in preclinical Huntington's disease

Popis výsledku v původním jazyce

ACKGROUND: Huntington's disease is a progressive neurodegenerative disease, genetically determined by CAG trinucleotide expansions in the IT15 gene. The onset of the symptoms is related to the number of CAG triplets. Because the patients are asymptomaticin the early phase of the disease, in vivo biomarkers are needed to follow up the reurodegeneration and to test putative neuroprotective approaches. One such promising biomarker is the diffusion MRI measured microstructural alteration of the white matter. METHODS: Seven presymtomatic, mutation carriers and ten age-matched healthy controls were included in the study. Diffusion parameters were compared between groups and correlated with measures describing neurodegeneration. In order to reduce the possible misregistration bias due to atrophy the analysis was restricted to the core of each fibre bundles as defined by maximal fractional anisotropy (Tract-Based Spatial Statistics). RESULTS: Decreased fractional anisotropy, along with increa
