Preservation of person‐specific knowledge in semantic memory disorder: A longitudinal investigation in two cases of dementia (pages 132-138)

The double dissociation involving person‐specific and general semantic knowledge is supported by numerous patient studies, though cases with preservation of the former are few. In this paper, we report longitudinal data from two cases. Their knowledge in both domains was preserved at the start of the investigation, but progressive deterioration was primarily observed on tests of general semantics. These data strengthen the evidence‐base for preservation of person‐specific knowledge in semantic memory disorder, and support its separate representation from object knowledge.
