Anarthria is the specific feature for Broca’s aphasia. Alajouanine et al. have suggested that it is the result of a triple motor dysfunc-tion: paretic, dystonic and dyspraxic. Motor aphasia is seen with in-farction of the Broca’s area. Such a lesion often extends to the pre-central gyrus. Pure anarthria occures with an infarct limited to this circonvolution and clinically then seems reduced to a nearly pure dystonic form. On the other hand, Luria have described the afferent apraxic motor aphasia, which is the result of infarction of the postcentral gyrus.
