INTRODUCTION Progressive anarthria is defined as a clinical entity with a degenerative origin consisting in progressive difficulty in articulating while grammatical, semantic and graphic aspects of language are preserved. It is included within the group of processes affecting restricted areas of the brain although its exact nosological location is not clear. We report two cases that progressed clinically towards frontotemporal dementia and corticobasal degeneration, respectively. CASE REPORTS. Case 1: a male who, at the age of 72, began with speech difficulties while comprehension and reading/writing skills were preserved. Three years later he developed apathy, bulimia, sexual indiscretions and aggressiveness, with preservation of visual memory, visual-constructional capacity and elementary writing skills. Case 2: a male who, at the age of 70, began with speech disorders, which were associated two years later to generalised slowness with Hoehn and Yahr stage II akinetic-rigid symptoms; another two years later, he developed a dystonic attitude and melokinetic apraxia in the left upper limb.
CONCLUSIONS The two cases, which were initially compatible with progressive anarthria, progressed clinically towards frontotemporal dementia and corticobasal degeneration, which are entities that are included in ‘Pick complex’. This is a concept that we believe to be useful from a clinical point of view, given the variability that exists in the histology of the entities that have been proposed as members of this syndrome group, together with the progression of the cases described in the literature and the ones we have reported in this work.
