Two cases of progressive anarthria are reported; we remarck their close but distinct relation with speech apraxia. Both of them were older female, with a progressive loss of speech, bilateral paresis of lower face, tongue and palatal muscles. They also had mild pyramidal signs and a fronto-subcortical cognitive deterioration. Brain TC and MRI were within normal limits. One of them had a possible progressive supranuclear palsy, the other one a possible corticobasal degeneration. The analysis of similar cases reports let us to conclude than there are several pathologies that can cause a progressive pseudobulbar palsy. The final diagnosis must be by postmortem examination of the brain.
