摘要: Huntington's disease is an incurable neurodegenerative caused by inheritance of expanded cytosine-adenine-guanine (CAG) trinucleotide repeat within the Huntingtin gene. Extensive volume loss and altered diffusion metrics in basal ganglia, cortex white matter are seen when patients with (HD) undergo structural imaging, suggesting that changes ganglia-cortical connectivity occur. The aims this study were to characterise pat- terns high anatomical precision premanifest early manifest HD, identify associations between genetic or clin- ical markers HD. 3-Tesla tensor magnetic resonance images acquired from 14
