Alexia without agraphia associated with right occipital lesion.
A 78 year old, right handed man developed the syndrome of alexia without agraphia due to a right occipital thrombotic stroke. The cerebral dominance test strongly suggests that his right hemisphere is dominant. This is believed to be the first case of alexia without agraphia secondary to a right occipital lesion in a right handed person.
متن کاملAlexia without agraphia.
Alexia without agraphia (also called pure alexia or word blindness) was the first of the disconnection syndromes (syndromes caused by disconnection of the right from the left cerebral hemisphere through interruption of the communication pathways between them) to be described. Déjerine in 1892 reported a patient who developed this syndrome after an infarct of the left occipital lobe and splenium...

In the late 19th century, Déjérine first described this entity in a man with associated incomplete right homonymous hemianopia from a lesion of the left fusiform and lingual gyri. He subsequently deduced that the left angular gyrus stored the visual representation of words (needed for reading and writing), and that disconnecting the visual inputs of both hemispheres from the left angular gyrus ...
متن کاملAlexia Without Agraphia: A Rare Entity
Pure alexia refers to an acquired disorder associated with the damage to medial occipitotemporal gyrus in the dominant hemisphere, which is also known as visual word form area (VWFA). VWFA is involved in rapid word recognition and fluent reading. Alexia without agraphia is a disconnection syndrome that occurs when the splenium is also damaged with the occipital lobe on a dominant side. We repor...
متن کاملPure agraphia: a discrete form of aphasia.
A 62 year old, right handed man developed a pure agraphia as the result of a left temporal lobe stroke. Isolated writing disturbances persisted for seven months until he had a second cerebrovascular accident resulting in total aphasia and right hemiplegia. A CAT scan obtained four months after the first episode showed a localised dilatation of the posterior portion of the left Sylvian cistern a...
