Aphemia, also called anarthria or severe apraxia of speech, is a rare disorder of speech production usually resulting from vascular lesions affecting the inferior premotor cortex of the left hemisphere. A patient presenting with aphemia as the sole manifestation of primary progressive aphasia (PPA) is reported.
A clinical case of alexia without agraphia is reported. The computerized tomography (CT) showed a left sub-cortical parieto-occipital hemorrhage. The cortical lesion probably involved the posterior part of the angular gyrus but spared the medial occipital cortex. There was no evidence of a corpus callosum lesion. The clinical findings associated with the alexia and the localisation of the haematoma could be compared to the case reported by Greenblatt as a "subangular alexia" and considered as a disconnection of the left angular gyrus from right angular gyrus and both left and right occipital areas. The semiological aspects of the present case have been found to consistently differ from the classical forms of alexia usually described. Some common features with phonological alexia have been observed.

Two cases of post-anoxic occipital blindness, one in an adult and the other in a child, are presented. A quantitative and qualitative semiological analysis was performed using tests described in a previous paper. Mechanisms underlying restitution of visual function were chronologically followed up over three years of rehabilitation. In both cases there was a noteworthy improvement in the visual function, related to the beginning of rehabilitation therapy. Five years of an almost complete cerebral blindness had preceded the improvement in case 2. Spatial construction acquisition and ontogenetic data are compared with the present data. It is suggested that there is a similar loss of activation in Broca's aphasia and cerebral visual disturbances of occipital origin.
