title: [Primary central nervous system degeneration in elderly patients. Characteristic imaging features].
abstract: Despite further development of new magnetic resonance imaging techniques, e.g., diffusion tensor imaging and 1H magnetic resonance spectroscopy, structural imaging will continue to play a major role in the diagnosis of primary central nervous system degeneration in ageing. Characteristic imaging patterns of multisystem atrophies and primary dementias as well as differential diagnostic features are demonstrated. While such features may have high specificity, their sensitivity is low especially in cross-sectional studies. Longitudinal studies are the optimal method to characterize the dynamic neuroanatomical correlates of the disease. However, according to disease duration and progression, neuroimaging will show increased overlapping and convergence of pathological changes in multisystem atrophy as well as in dementia.
