GOMEZ, Pablo G.  e  POLITIS, Daniel G.. Correlations between praxis and working memory in the frontal variant of frontotemporal dementia. Neuropsicologia Latinoamericana [online]. 2011, vol.3, n.2, pp. 23-30. ISSN 2075-9479.

It has been reported in the literature that a deficit in working memory may affect praxis performance. The aims of this study are to evaluate the presence of apraxia in patients with the frontal variant of frontotemporal dementia, to assess the occurrence of correlations between apraxia and working memory, and to look for evidence of a working memory specific for gestures. Material and methods: We administered to 23 patients diagnosed as having the frontal variant of frontotemporal dementia the praxis cognitive assessment battery and two tests of working memory. Results: We found significant correlations between the performance on praxis tests and the measures of working memory. The performance on gestural working memory was dissociated from that in visual and verbal working memory. Conclusions: These results reaffirm the importance of working memory in the production of praxis and point to the possibility of a working memory specific for gestures.
