 We report the case of a 72-year-old right-handed woman who showed various stereotypies as semantic dementia progressed. At initial assessment, MRI showed focal atrophies in the anterior temporal lobes, which were more severe in the left lobe. She exhibited complicated stereotypies such as wearing clothes of the same color or using the same phrases. At a three-year follow-up, MRI showed increasing atrophy in the caudate nucleus and frontal lobes in addition to that in the temporal lobes, at the same time, she displayed simpler stereotypies for example, clapping, chewing, and ‘palilalia'. These findings suggest that the simplification of the stereotypies observed in this case was associated with basal ganglia-thalamo-cortical circuit dysfunction.
