ABSTRACT

One of the most common disconnection syndromes is undoubtedly that of alexia without agraphia. They are called disconnection syndromes because they are generated from a lesion to the corpus callosum, a structure that through its fibers connects the functions of both hemispheres to carry out integrated and complex actions. Specifically, the splenium of the corpus callosum is distal to irrigation, receiving blood supply from different vascular territories. This is why it suffers most when a hemodynamic phenomenon decreases the cerebral blood supply.
Here is a classic case that explains these phenomena.
