Dissociation of social cognition and executive function in frontal variant frontotemporal dementia.

abstract：:This article describes an investigation into the residual writing skills of a severely dysgraphic patient (DA). We found that they were powerfully influenced by a number of lexical variables (lexicality, frequency, imageability, length and geminates). His error pattern was characterized by semantic, lexical, substitut...
