    Abstract:
    INTRODUCTION: Pure alexia is a syndrome characterized by the inability to read aloud in the absence of agraphia or apnasia. CLINICAL CASES: Three clinical cases showing this syndrome are presented. Case I had a left occipital lesion compatible with a subacute haematoma. He had problems with reading, visuo-spatial recognition, digital gnosia and memorizing texts. One year later there was considerable improvement in most of the sub-tests evaluated. There was still deficient colour naming right/left orientation and understanding of letters and words. Case 2 presented with a right homonymous hemianopia and slight left paresis. He had a small left occipital ischaemic infarct. One year later there was improvement on testing, with some deficit still in visual recognition, naming colours and memory. Case 3 presented with right homonymous hemianopia, slight right paresis and a left occipito-parietal expansive lesion. He had defective reading, choosing and naming of colours, right/left orientation and memory. On later evaluation, considerable improvement was seen. There was still colour agnosia, although less severe and mild 'laziness' of the right side. CONCLUSIONS: In the review of the literature, the disorder and the contributions of various authors, from Déperine in 1892 to the present day, are considered in detail.
