Cortical and Non-Cortical Myoclonus of Creutzfeldt-Jakob Disease

B, vasculitis, and syphilis was excluded by the results of biochemical screening tests. EEGs showed PSDs with the largest amplitude over the central parietal area of the right hemisphere (i.e. C4 and P4; fig. 1 a). Magnetic resonance imaging study showed restricted diffusion over the right frontal, parietal, and occipital lobes in diffusionweighted imaging (DWI) ( fig. 1 b). 99m TcTRODAT-1 reve...
