Alexia without agraphia

Alexia without agraphia is a form of alexia which involves an infarct to the posterior cerebral artery (which perfuses the splenium of the corpus callosum, among other things).

The resulting deficit will be "alexia without agraphia" - i.e, the patient can write but cannot read (even what they have just written).

It is also known as "Dejerine syndrome" (after Joseph Jules Dejerine, who described it in 1892 ), but it should not be confused with medial medullary syndrome, which shares the same eponym.

It can be associated with a lesion of the occipital lobe and splenium of the corpus callosum.
